Care and Feeding of Brick Siding

Having brick siding installed on your house gives it a classic look. Unfortunately, a lot of people view brick as an install-it-and-forget-it option and allow that look to deteriorate over time. Brick homes require basic maintenance and care just like vinyl and wood siding do, though the specifics of maintenance may be a little bit different. It’s just like with anything: If you want the look, you have to put in the work to keep it up.Fortunately, maintaining your brick isn’t that difficult. Even better, the maintenance you do now can help prevent your brick siding needing major repairs in the future. So long as you’re willing to put forth a little effort, you should be able to keep your home looking great for years to come.

Cleaning Your Brick

The brick on your home is exposed to the elements on a 24/7 basis, and the rough surface of most bricks make them ideal for picking up dust and dirt. This can lead to damage over time, so once or twice a year you should take the time to clean your bricks. Most of the time this is as simple as spraying them down with a garden hose to remove any dirt and grime that’s built up on your home, though particularly tough spots and areas may need a scrub brush with soapy water as well. Avoid the temptation to use a power washer as the high water pressure can damage the brick.

Vegetation and Mildew Removal

While some plants such as ivy provide what some consider a dignified look, any vegetation that grows on your brick will damage it. Remove any vines, moss or other plants that you notice growing up your brick wall, making sure to wear gloves in case the plant is something that you don’t want to touch like poison ivy. You should also periodically check your brick for signs of mildew or mold, both of which can damage the brick surface as they grow. Scrub the area where you notice these growing, spraying them with a diluted solution of bleach and water to kill off any remaining remnants or spores. It’s a good idea to wet down the brick before you spray it, though, as this will prevent bleach from collecting in deeper contours of the brick and causing discoloration.

Checking for Damage

There are two types of damage you should check for at least once per year when you have a brick home. The first is impact damage, resulting from something hitting the brick and causing cracks, chips or other damage to it. This can come from a variety of sources, including things as ordinary as a lawnmower throwing a rock. The second type of damage to look for is water damage, which occurs when rain or splashing water repeatedly hits an area of the brick and starts to wear it away. Both of these can damage not only the bricks but the surrounding mortar as well. When damage is found, scrub the area to remove any loose material and keep an eye on the area to see if the damage gets worse over time. If the damage is caused by splashing water or other environmental issues, you might also adjust your landscaping or install additional drainage to redirect water and prevent further damage.

Repointing and Repair

As brick and mortar become damaged, you may need to make repairs from time to time. If the damage is just to the mortar, scrape and chisel away any damaged portions and apply new mortar to the entire area where wear and damage is present; this is typically known as repointing. If there are bricks that are damaged to the point that they need to be replaced, chisel away the mortar surrounding those bricks until they can be removed. Apply fresh mortar and new bricks to fill the damaged area.

Heating Sources Explained

There are a lot of different options available when it comes to heating your home. Some of them, you’re likely really familiar with, while others are newer options that you may not have heard of. Regardless, understanding how different heating options work is an important part of deciding how to best heat your home. Whether you’re building the home of your dreams or just remodeling your existing home, here’s some info on some of the heating options you might encounter.

Gas Heat

As the name implies, gas heat means that your system produces heat by burning a flammable gas (typically propane or natural gas). Depending on where you live, the gas either comes from a city-supplied utility line or a standalone tank that sits on your property. The heater functions by adjusting the gas passing through the heating chamber to make flames larger or smaller, controlling the amount of heat the flames release into the air that passes through the chamber. Propane heat may also come in other forms, such as gas fireplaces that serve a decorative purpose, as well as providing localized heat.

Forced Air

A forced air system is one that uses fans or other blowers to move air over a heating element and throughout the heating system’s ductwork. These are some of the more common heaters that you will encounter, as variations of forced air heating is used in most central heat and air systems and in many portable heaters.

Baseboard Radiators

There are a few different types of baseboard radiators that you might encounter. These heaters sit at or around floor level around the edges of a room, generating heat and allowing it to rise naturally throughout the room or house. Different materials are used in these heaters, with more modern varieties using pipes filled with heated oil to hold and radiate heat at a lower power cost than similar heating options like older, electric floor radiators.

Radiant Heat

An increasingly popular option for heating the home comes in the form of radiant heat flooring. A closed liquid heating system is embedded in concrete or other flooring material, heating the floor itself and allowing that heat to radiate upward naturally to provide gentle heat over a larger area without the need for high energy costs. There are a wide range of radiant heat options available, including everything from electric heating to systems that are heated from a wood stove outside of the home.

Solid Fuel Heaters

Also referred to as “pellet stoves” or “biomass heaters”, solid fuel heaters are stoves or other heating units that burn solid materials such as wood pellets or shavings instead of liquid or gas fuels. This is seen as something of a green option for homeowners who want to use wood and other materials that would otherwise be considered waste by the forestry industry. The fuel pellets or shavings are loaded into the heater and released into the burning chamber gradually, providing more control over the temperature and heat intensity than you would have with traditional wood-burning stoves.

CHP Systems

An emerging technology, “combined heat and power” or CHP heating systems are designed to be another environmentally-friendly heating option. These systems use a generator that produces power for the home or other buildings on the property, then reclaims heat energy released by the generator to heat the home. These systems are not yet available in all areas and may not be for everyone since they do provide more than just heat. For those planning for the future, however, keeping an eye on CHP systems may be a way to heat the home while simultaneously reducing dependence on external power.

The Post-Inspection Negotiation Two-Step: What You Can Expect

As with a lot of problems, the answer is a resounding “It depends.”

Gauging Severity

One big determining factor in how problems found in a home inspection are dealt with is how severe the issues are. A major problem with a property can be a deal breaker for many buyers. Depending on where you live, such a problem may even have to be addressed before the property can be sold. State-level restrictions vary, but most are rooted in making sure that sellers can’t avoid fixing potentially dangerous problems or leave them for the buyer to discover on their own. Even if a problem isn’t critical, most states require that any problems found by a home inspection be disclosed to potential buyers. This disclosure is a big deal, as it can significantly affect how much the buyers are willing to pay.

Loan Program Requirements

Beyond repair and disclosure requirements that vary from state to state, different loan programs (such as those offered by the Federal Housing Authority or Department of Housing and Urban Development) may have additional requirements when it comes to problems discovered during a home inspection. Many programs have very specific guidelines regarding the condition of the property that a buyer can purchase using those loans. If a loan program won’t allow a purchase while unsatisfactory conditions exist, the issues must either be repaired or have satisfactory arrangements made to facilitate the repair before the purchase can continue. Keep in mind that not all loan programs will make allowances for future repairs, either; in those cases, the repairs will either have to be made in full or the buyer will have to find a different lender that does not follow the same strict requirements.

Negotiating Repairs

In the event that there aren’t specific regulations at the state level or restrictions in the buyer’s loan program concerning problems with the property, it falls to the buyer and the seller to determine what repairs will be made. This is typically part of the price negotiation, as buyers are willing to pay more for a property that they don’t have to make extensive repairs to. In many cases, sellers may offer to cover the most pressing repairs and address any serious issues while the buyer assumes responsibility for any other issues found in the buyer’s home inspection disclosure. In many cases this will be agreed to in writing, either at the request of one of the parties or as a condition of the mortgage loan that the buyer is using for the purchase. By formalizing the agreement in writing, it ensures that both parties understand their responsibility and protects the seller from potential legal action regarding issues that weren’t addressed (provided that the seller completed all of the repairs that they agreed to.)

Market Strength

The strength of the housing market can have a big effect on who does the bulk of repairs on a property. If similar properties are plentiful and interest rates are low, it creates what’s referred to as a “buyer’s market”; buyers have a lot of options and can easily walk away from the purchase if they don’t get what they want. In this situation, the buyer has a lot of leverage and can usually get the seller to agree to either a lower price or a higher percentage of the repairs. When the opposite occurs and there are few choices and higher interest rates, a “seller’s market” is created. Buyers can’t walk away as easily and be guaranteed a good deal elsewhere, so sellers can often hold their ground more and get buyers to agree to higher prices or a greater percentage of repairs.

Heat Recovery Ventilation (HRV) & Air Exchange Systems

Heat Recovery Ventilation (HRV) & Air Exchange Systems There are some commonly asked questions about the installation, maintenance and operation of home ventilation systems. If you have others, please contact us and we'll be happy to answer them. Why is proper ventilation in my home so important? Controlling Moisture Levels in your home – Moisture comes from cooking, bathing and breathing. Too much moisture may not only cause condensation which can damage the structure of your home but also provides a breeding ground for mould, mildew & bacteria. Ridding your home of pollutants and Contaminants –construction materials used in new homes and furniture as well as regular household products may release toxic fumes and gases that contribute to poor indoor air quality and possible health issues.​ How is a Heat Recovery Ventilation System different from a regular air exchanger? Both Air Exchangers and HVR systems move old, stale air out of your home and draw fresh air in. The difference is that an air exchanger expels heat – as well as your money! A HRV system transfers (recovers) as much as 80% of the heat energy from the out-going air to the clean fresh air coming in. Good for the environment and for your wallet. Can a HRV system be installed in an older home? Yes. Clean Air Solutions will install a ventilation system that is custom fit for your home. How do I maintain my ventilation system once it’s installed? Regular Maintenance of your HRV system is required to keep it working properly. In fact an improperly serviced HRV may not only contaminate the incoming air​ but also reduce the transfer of heat energy from 80% to as low as 20%. How do I adjust the HRV settings? Clean Air Solutions recommends these settings for your HRV system: Spring | Mid-June Turn your wall control to a high setting (above 70) Fall | Mid-October Turn your wall control back to its regular setting (usually 45) Every 3 Months Remove & Clean Filters Clean Exterior Vents Annually Book a 10 Point Service Plan appointment with Clean Air Solutions Will a HRV work with all heating systems? Yes. It is independent of the heating system in the house. Are there health benefits to installing a HRV? According to Health Canada, 1 in 4 Canadians have reported health problems linked to poor indoor air quality. Indoor pollutants can contribute to health issues such as allergies, headaches, fatigue, asthma and other respiratory conditions. Removing contaminated air from your home and bringing in fresh air can alleviate these symptoms. Does the same air get recycled? No. There are two vents: one draws the warm stale and polluted air from the living areas of your home through the HRV system to be released outside. The second draws a continuous stream of cool fresh air in through the system to be distributed throughout your home. The ducts run side by side and only the heat energy is transferred from one to the other. How much does it cost to install a HRV system? The cost to install a HRV will vary depending on the size of the home, whether it’s newly constructed or requires retrofitting, the complexity of the installation, etc.

If you have a problem, talk to your neighbors first

Does your neighbor’s music keep you up at night? Are their kids bothering your dog? Talk to them. Having an in-person confrontation can feel scary, particularly if you need to say something you’re worried your neighbor won’t like, but talking things through face-to-face should be the first thing you try, says Diane Gottsman, national etiquette expert, author of Modern Etiquette for a Better Life, and founder of The Protocol School of Texas. “Go with a polite, non-confrontational attitude and you might be surprised how well most people respond,” she says. “Also, a plate of cookies never hurts.” If talking face-to-face doesn’t work try these 12 steps for dealing with bad neighbors. As a last resort, escalate issues to your HOA or local authorities.

Have a neighborhood safety plan

“Wildfires, earthquakes, floods, hurricanes—you never know what will happen these days and if you ever get stuck in an emergency situation your neighbors are going to be the people you turn to first,” says Julie Bowman, MPH, emergency preparedness and public health expert. This is why it’s so important to set up a safety plan with your neighbors, she says. It can be as simple as printing out a map and marking where people are who will need help―like the elderly—to as complex as a neighborhood watch program or more. What you need will vary by community but start with these tips for making your own neighborhood plan from the National Crime Prevention Council. This is what to do if your neighbor’s tree has grown into your yard.

Look for ways to help neighbors instead of seeing them as problems

Does your elderly neighbor have an unkempt yard? Does the single mom next door always leave her garbage cans out? Are the kids unruly at the bus stop? Instead of gossiping or complaining, reach out and see if you can find a way to help—for instance, mowing your neighbor’s lawn, bringing her trash cans in when you bring in yours, or offering to stand outside with the kids until the bus comes. “Often there are very simple things you can do to solve the problem and not only will you brighten someone’s day but there may come a time when you need help and you’ll want your neighbors to be there for you,” Gottsman says.

Smile and wave

Thanks to the Internet we’re interacting with people around the world more than ever but that may mean we’re also interacting much less with the people right next door to us. Fortunately, it doesn’t take much to change that, says Bonnie Tsai, founder and director of Beyond Etiquette. “A smile, a wave, a brief exchange of pleasantries, can inspire a lot of goodwill with your neighbors,” she says. It doesn’t take much and makes the neighborhood a much happier place overall.

Learn your neighbors’ names

This is Good Neighboring 101 but you’d be surprised how many people have lived next to someone for years and don’t know the first thing about them. Good neighbors will make the little extra effort to learn their neighbors’ names and a few things about their lives, like how long they’ve lived in the area, where they work, or if they have kids or pets, Tsai says. The payoff can be great. It will make you feel more connected to those around you but it can also help make your neighborhood safer—neighbors who know each other are more likely to watch out for each other. One of the best defenses against a home break-in is a neighbor who knows your schedule and notices something out of the ordinary. Check out 15 more ways you can be a good neighbor.

Give your neighbors the benefit of the doubt

Do the teens next door have crazy hair and tattoos? Does the neighbor across the way practice a “weird” religion? Does the guy next door drive a big white van? Instead of assuming your neighbors are hoodlums, terrorists, or serial killers, give them the benefit of the doubt, Gottsman says. This doesn’t mean ignoring when people do bad things or putting yourself in unsafe situations, it simply means seeing people as people first and looking for other possible explanations for their behavior besides negative ones. You don’t have to be their best friend but you should treat them with respect and kindness, no matter what, Tsai says.

Don’t fight with your neighbors on social media

Keyboard warriors are everywhere these days, using neighborhood apps and social media groups to share their indignation over everything from politics to teenagers trick-or-treating to dog poop. While this might garner you a lot of support, it doesn’t do much, if anything, to solve the problem and just marks you as a complainer, Gottsman says. “Hiding behind a keyboard is a very passive-aggressive way to deal with problems you may have with your neighbors,” she says. If you have a problem with a particular neighbor, talk to them offline and certainly don’t call people out by name on social media, she says. If your issue is more widespread—say a dangerous intersection by a bus stop—you’ll get better results calling the school, the bus company, the HOA, or the police directly. Besides, engaging on social media in a negative way could make you one of these real-life nightmare neighbors.

We often reserve our best manners for people we’re trying to impress, like a boss or potential partner, and let them slide when we’re at home. While it’s fine to be more casual with your neighbors than your coworkers, you should always be polite, Tsai says. This means saying “please” and “thank you” or “excuse me” and other niceties. Even if you find them annoying or rude, set a good example. Civilization is built on people being civilized to each other! Do you know these 10 things your neighbors won’t tell you?

Stay positive about your community online

Neighborhood apps, Facebook groups, and community message boards have replaced the backyard fence of older days, becoming the main way neighbors share information. These can be a great tool, as long as you remember your manners online as well. “The whole point of these groups is to build community and camaraderie so keep your posts and comments positive and productive,” Gottsman says. “Before posting something, ask yourself, ‘What is the benefit of this?’ and ‘How would I feel reading this?’” And if someone is mean to you online? “Take the high road and simply reply, ‘Let’s discuss this in person,’” she says. Can you guess the things your neighbor wants you to STOP doing?

Do your best to follow community rules

Many fights between neighbors start over a disagreement about the rules and how someone is or isn’t following them. Most of these can be avoided by simply doing your best to abide by the standards set by your neighborhood, Gottsman says. Whether that’s taking down holiday decorations by the end of January or not playing music outdoors after 10 or keeping your garbage cans out of sight, these were things your neighbors have decided are important so you should make a good faith effort to follow them, even if they seem silly to you. If you live in an area with an HOA, these rules were likely spelled out in your signed contract. Otherwise, you might have to dig a little deeper to figure out what the expected norms are in your neighborhood.

Crawl Space Care: Insulation, Ventilation, Encapsulation, Oh My!

Updated on July 31st, 2019
Crawl spaces are often out of sight and, consequently, out of mind, making them easy to neglect. But don’t “space out” on your crawl space! Without proper care, your crawl space is susceptible to moisture, heat loss, pests, and a host of other complications. These common problems can damage your home’s foundation, cause sky-high energy bills, and introduce toxins to the air you breathe. With as much as 40 percent of the air in your home originating from your crawl space, learning to care for this area plays a big role in your health and the long-term health of your home.
crawl space

What is a Crawl Space?

A crawl space is a small space, ranging from one to three feet in height, that resides between the bottom floor of your home and the ground. A crawl space provides extra room for electrical wiring, plumbing components, and HVAC equipment. As the height of the crawl space is limited, getting into the area must be done by crawling, either on the stomach or the hands and knees (hence the name). For those searching for homes, or who own homes in close proximity to water or swampy areas, like Florida, exploring crawl spaces can be a necessary part of a home inspection.

What’s the Difference Between Crawl Space vs. Basement?

Crawl spaces are typically used in damp climates, where the ground is regularly too wet for basement construction. Supporting the home off of the ground keeps it away from moisture that could cause damage. In coastal areas where the soil is sandy, a crawl space can alleviate potential basement problems, like excessive water buildup that could put pressure on basement walls. Crawl spaces are also sometimes preferred in construction when a basement is too costly. Installing a crawl space is cheaper than installing a basement. crawl space A basement is a popular type of foundation that can add space and functionality to a home. Basements are often used as storage space, living areas, or both. A basement combines elements of a slab and crawl space. The floor in a basement is very similar to a slab, and the support system used under the basement floor is the same as what is used in a crawl space. Although basements can be a great addition to a home, they cannot be built in areas with high moisture levels or unsettled soil. They also happen to be the most expensive type of foundation to build.

Crawl Space Solutions for Common Problems

Problem: Moisture

Homes with poor ventilation are more susceptible to crawl space issues than others. Without regular evaluation, you may not know there is a problem until it’s too late. Signs of excessive moisture throughout the home are often readily noticeable, but signs of moisture in your crawl space may be harder to detect. Unfortunately, moisture in a crawl space can be just as problematic, causing complications such as mildew, dust mites, mold, and wood rot. When there is nowhere left for moisture to go within a crawl space, it can then travel into your insulation, flooring, and walls to create even larger problems. Crawl spaces with exposed dirt most commonly have trouble with an excess of moisture.

Solution: Vapor Barrier

A vapor barrier is one of the best ways to protect your home against the encroachment of moisture. Essentially a large plastic sheet placed over the base of a crawl space, vapor barriers are intended to fully cover any exposed dirt. While this doesn’t completely eliminate moisture, it does slow the process significantly. At 50 to 70 cents per square foot, sheet plastic is a cost-effective barrier for moisture in your crawl space. A vapor barrier can be a DIY project if you’re willing to get down and dirty, but the labor that goes into covering the entire ground area can be challenging to accomplish on your own. You’ll need a friend to help you pass the rolls of sheet plastic back and forth through the crawl space, or if this sounds too labor-intensive, a professional contractor may be the way to go. man in crawl space

Solution: Encapsulation

If a vapor barrier alone isn’t enough to tame moisture and ventilation problems, encapsulation can be a great alternative. The first step in this process involves a vapor barrier coupled with sealing tape and coverage of walls and ceiling areas. A complete encapsulation includes drain tile, a sump pit and pump, concrete, insulation, and a dehumidifier to properly condition the air. While placing a vapor barrier can be done independently, encapsulation is best handled by a professional. The installation process takes expertise, and installing a dehumidifier is best left to a trained technician. Hiring a contractor for this work costs about $5,500 on average.

Problem: Energy Loss

A crawl space isn’t a livable part of the home, but insulation is still important to keep the heat in. Crawl spaces can be a major source of energy loss. If you find yourself running your furnace all winter long, driving up high energy bills, yet still feel cold on the ground floor of your home, your crawl space could be the issue. If your crawl space isn’t properly insulated from the cold, you could be wasting energy and driving up your utility bills. Cracked Foundation

Solution: Insulation

Insulating your crawl space depends on the general climate in the area. In warm or dry areas, insulation can be limited to just the area between the floor joists. However, in subfreezing temperatures, insulating the walls and sealing off the crawl space is most effective. A professional can evaluate the state of your crawl space, make a recommendation, and handle the insulation process.

Problem: Pests

Rodents and insects can be a problem anywhere in your home, and a crawl space is no exception. Crawl spaces can easily become a dwelling for pests if they are not properly maintained. Since most homeowners do not spend much time in their crawl space, it may be harder to determine if there is a pest problem. Pests such as mice, rats, termites, carpenter ants, spiders and more have the ability to damage insulation, crawl through vapor barriers, dig into wood, and even tunnel into your main living spaces.

Solution: Pest Control

Proper crawl space maintenance, including encapsulation, can keep your property safe from pests. When all entrances and exits are sealed, the possibility of rodents and insects gaining entry to your home is almost impossible. If you do see signs of pests, partnering with an exterminator can treat problems at the source.

Crawl Space Inspection Checklist

A crawl space inspection is typically included in a standard home inspection when buying or selling a house. This is an area where issues tend to arise and can throw a wrench in the home sale. Both home sellers and buyers should be aware of the state of the crawl space in order to mitigate any potential problems prior to the sale. Here are the red flags that professionals look for during a crawl space inspection:
  • Electrical wiring issues
  • Plumbing issues
  • Moisture (standing water, damp insulation or warped building materials)
  • Pests (bugs, termites, rats, mice)
  • Mold and mildew
  • Ventilation issues
  • Cracks in the foundation
As a seller, you may want to have your crawl space inspected prior to listing it on the market. That way you are aware of any issues and can have them fixed before the sale, or adjust the sale price accordingly. As a homeowner, maintaining your crawl space is critical to the health and longevity of your home. That means doing an annual inspection and attending to problems as they arise, as well as taking preventative measures to keep your house healthy. If crawling under your home doesn’t seem like fun, you can always partner with the pros and hire someone to ensure your crawl space is in good hands. With these tips and fixes, you can be sure this “foundational” part of your home is properly maintained for years to come.

Moisture in basements: causes and solutions

Moisture in basements: causes and solutions

By John Carmody; Brent Anderson; and Richard Stone, Extension educator University of Minnesota
This page briefly describes moisture sources, moisture movement mechanisms and typical basement moisture problems. Then, a step-by-step process for addressing each problem is presented along with several detailed approaches to solving the problem.
Moisture problems in basement, rainwater, groundwater, interior moisture.

A problem that can damage your health and home

Moisture problems in existing basements are very common, but often are not understood or properly treated. In a basement that is seldom used and separate from the living spaces above, this may not present a great problem. However, most basements in Minnesota are connected to the rest of the house through ductwork or other openings. In addition, basements are increasingly used as finished living and bedroom spaces. In these cases, moisture problems are not only annoying and uncomfortable, but can lead to significant health problems. Molds and mildew can grow in damp carpets and beneath wall coverings. Finishing a basement without first dealing with the moisture problems can result in making health conditions worse and lead to significant damage as well. Basement water problems are solvable, but there is a cost to doing it right.

Understanding the problem

To correct basement moisture problems, it's necessary to understand where the water is coming from and what mechanisms permit it to enter the basement. There are just three sources of moisture:
  1. Liquid water from rain or ground-water.
  2. Interior moisture sources such as humidifiers, unvented clothes dryers, bathrooms and cooking, as well as the moisture in concrete after construction.
  3. Exterior humid air that enters the basement and condenses on cooler surfaces.
Moisture is transferred from the outside of the building to the basement interior by four mechanisms:
  1. Liquid water flow.
  2. Capillary suction.
  3. Vapor diffusion.
  4. Air movement.
Sometimes problems are traced to poor construction with cracking, settling foundations. In many cases, however, houses and basements can be structurally sound but are often not properly built to handle water drainage. Failure to slope the ground surface away from the foundation or lack of a good gutter and downspout system is common. Missing or nonfunctioning subsurface drainage systems are also found relatively frequently. These problems can all be addressed and corrected if a systematic approach is used. This page briefly describes moisture sources, moisture movement mechanisms and typical basement moisture problems. Then, a step-by-step process for addressing each problem is presented along with several detailed approaches to solving the problem.

Symptoms

  • Water trickling out of walls.
  • Standing water on floor.
  • Saturated base of concrete block walls; a ring of dampness.
  • Damp, humid air.
  • Condensation on cold walls and floor in summer.
  • Odor, mold and mildew.
  • Deterioration of carpet or wood.
  • Rot and decay of wood headers, joists, sill plates and columns.
  • Staining and blistering of wall covering.
  • Efflorescence, spalling of concrete or masonry.

Basement moisture sources

Rain and groundwater entering basement.
Rain and groundwater

Rain and groundwater

In a 1-inch rain, 1,250 gallons of water fall on the roof of a 2,000-square-foot house. Without proper grading, gutters and downspouts, some of this water flows into the basement. The below-grade water table can also rise due to flooding or seasonal site conditions. This is why drain tile systems are recommended around basement walls even in sandy or gravel soils.
     
Interior moisture sources in basement.
Interior moisture sources

Interior moisture sources

Moisture is generated inside of basements from people and their activities. Common sources are humidifiers, unvented clothes dryers, showering and cooking. When basements are finished, these activities increase. Another source that can be thought of as internal is the moisture contained in new concrete after construction. In a typical house, this can amount to 0.2 gallons per square foot of wall, and 0.1 gallons per square foot of floor. It may take many months or even years for a new house to come into equilibrium with its environment.
Ventilation with humid outside air.

Ventilation with humid outside air

In the summertime, basement windows may be opened for fresh air. If the outside air is warm and humid, it will condense on the cool basement wall and floor surfaces. Many homeowners see this moisture and believe they are experiencing basement wall leakage, when in fact the accumulated moisture is from condensation.

Moisture movement mechanisms

Moisture movement mechanisms - capillary suction.
Capillary suction

Capillary suction

Capillary suction moves moisture through porous materials. The water can be drawn upward through small pores in the concrete footing and slab and laterally through walls. This effect creates the ring of dampness seen at the base of many basement walls. This is very common at cold joints. Water can rise by capillary draw significantly as shown below: Soil type and amount of capillary rise:
  • Gravel - Less than a few inches.
  • Sand - 1 to 8 feet.
  • Silt - 12 to 16 feet.
  • Clay - 12 to 20 feet.
Moisture movement mechanisms - Air leakage through walls and floor.
Air leakage through walls and floor

Air leakage through walls and floor

In most houses, a stack effect is created because warm air rises. This induces a negative pressure on the basement and draws moist air in through any cracks or openings in the foundation including open sump pits. For this reason, sumps should have an airtight cover. With a concrete block foundation, moist air is drawn through the block cores, especially if they are left open at the top course.  
 
 
Moisture movement mechanisms - Vapor diffusion through foundation walls.
Vapor diffusion through foundation walls

Vapor diffusion through foundation walls

Vapor diffusion is the movement of moisture in the vapor state through a material. It's dependent on the permeability of the material and the driving force of vapor pressure differential. In a basement, vapor can diffuse from the wetter ground through concrete walls and floors toward the dryer basement interior. Vapor retarders such as foundation waterproofing and polyethylene slow down this process.

Typical causes of basement moisture problems

Causes of moisture problems - inadequate grading.
Inadequate grading

Inadequate grading

PROBLEM: If the ground around a foundation is level or slopes toward the house, water is directed into the basement. The soil next to the house is often backfilled without proper compaction and later settles. This is especially true under stoops where water can collect next to the basement wall. SOLUTION: Place earth around the house so that it slopes away from the foundation wall a minimum of 1 inch per foot for at least 6 feet.  
 
Defective or missing gutters and downspouts contribute to basement moisture.
Defective or missing gutters and downspouts

Defective or missing gutters and downspouts

PROBLEM: Missing gutters and downspouts cause rainwater to be directed toward the foundation perimeter. A downspout without an extender or splashblock is worse than no downspout at all. It is depositing the huge volume of rainwater from the roof in a single concentrated location near the basement. SOLUTION: Place a minimum of one downspout per 50 linear feet of roof eave. Extensions should discharge water at least 4 feet beyond the wall. Sloped concrete sidewalks around basements are very effective in directing rain runoff.  
Improperly designed window wells cause water to flow toward basement.
Improperly designed window wells

Improperly designed window wells

PROBLEM: Window wells are like a drain right next to the basement wall. Often they are improperly built so that any water is directed toward, rather than away from the foundation. SOLUTION: Window wells should be filled from the footing to the window sill with 3/8- to 3/4-inch coarse aggregate. A supplemental drain tile extension should extend from the footing to the base of the window well.  
   
Ineffective drain tile and sump pit

Ineffective drain tile and sump pit

PROBLEM: Many existing houses simply have no subsurface drainage system. This comes from a time when basements were not used as habitable space. In other cases, the systems don't work for a variety of reasons, such as collapse of the pipe, clogging of the pipe with silt and/or tree roots or a broken connection to the sump. The sump pit usually contains a pump designed to lift the water to the ground surface outside the foundation wall. This pump can fail.  
 
SOLUTION: See approaches 2 through 5 that follow.
Improper drainage with underslab ducts
Improper drainage with underslab ducts

Improper drainage with underslab ducts

PROBLEM: If heating ducts are installed beneath a basement floor slab, the drainage system may be inappropriately left at a level higher than the duct. In effect, the duct becomes the drainage system. With standing water within the heating duct, there are potentially serious health consequences from mold contamination. SOLUTION: Heating ducts placed beneath the basement floor must be insulated, watertight and sloped to collection points for drainage and cleaning. A drain tile and coarse aggregate can be placed under the ductwork.
Structural cracks let water in basement.
Structural cracks

Structural cracks

PROBLEM: Concrete and concrete block foundations usually develop some cracks. They can be severe if floor joists are not properly connected to the foundation wall, thus permitting the wall to move. Also, soil settling causes cracking. Places where walls meet rigid structures like the fireplace often crack as well. Usually, drainage removes the water from cracks, but repair may be necessary. SOLUTION: Proper footing design and proper connection between the foundation wall and the structure above are required (e.g. anchor bolts or straps at the sill plate and floor joists nailed to the sill plate).

An overview of solutions to basement moisture problems

The best way to approach any building problem is to first do the things that are easy and low cost. Then proceed in a logical order doing the next least costly technique with the most positive likely result. With moisture problems, the best approach is almost always to remove or control the source of the moisture, not to try to stop it at the last line of defense.
  1. First, the simplest and least costly techniques are to remove excessive internal moisture sources in the basement (humidifiers, cooking) and ventilate other sources (clothes dryer, bathroom).
  2. Second, if condensation in the summer is the problem, do not ventilate the basement directly with warm, humid air. Ventilation through an air conditioning system or with a dessicant-type heat exchanger is recommended.

Dehumidification is not a permanent solution

Dehumidification can be used as a means of reducing the symptoms of humidity and odor in a basement, but it is not a permanent or complete solution. In fact, if a dehumidifier is used in a basement with moisture problems, it may cause greater damage. By drying out the basement air, moisture is drawn into the basement more rapidly causing efflorescence and spalling of concrete and further damage to interior finishes.

Interior membrane or coating is a temporary solution

It is appealing to solve a basement moisture problem with a membrane or coating on the inside. It's less expensive than a drainage system and seems to work for a time in some cases. The water is still there, however, and eventually these systems deteriorate or simply move the water to another pathway into the basement.

Recommended approach

Evaluate gutters, downspouts and surface grading: The recommended approach after removing interior moisture sources is to evaluate the gutters, downspouts and surface grading around the house. These should be corrected first and may solve the problem. Interior or exterior drainage system: Then, if a moisture problem persists, proceed with an interior or exterior drainage system. All of these techniques are described below. If your goal is to finish a basement that has water problems, it is recommended to first deal with the water problem. Sub-slab depressurization system: An active sub-slab depressurization system including a washed-rock layer below the slab is recommended. This draws moist air from beneath the slab and may help to reduce the amount of moisture vapor that enters the home through openings in the slab. It also assists in controlling radon and other soil gases. Sumps and other open connections to the soil outside the foundation and below the slab should be blocked and sealed. More information on soil gas management can be found in "Building Radon Out," a booklet available in electronic format (PDF) from the Environmental Protection Agency.

Step by step process

  1. Control interior moisture sources.
  2. If summertime, don't ventilate with outside air.
  3. Correct grading, gutter and downspout system.
  4. Provide an interior or exterior drainage system.

Notes

  • A dehumidifier can help reduce the symptoms of humidity and odor, but doesn't solve the problem.
  • A membrane or coating on the interior without providing drainage generally won't solve the problem in the long term.
  • Walls must be dry before insulating. Slabs must be warm and dry before carpeting.

THE DIFFERENCE BETWEEN AIR BARRIERS AND VAPOUR BARRIERS

THE DIFFERENCE BETWEEN AIR BARRIERS AND VAPOUR BARRIERS

Can a house be too airtight? No it cannot. The difference between air barriers and vapour barriers is often confused. Also confused, is which one is more important.

The difference between air barriers and vapour barriers

The job of a vapor barrier is to prevent vapor diffusion, and the job of an air barrier is to stop air leakage through differences in air pressure. A wall system should have one vapor barrier, but can have many air barriers. A vapor barrier can act as a very effective air barrier, but an air barrier does not (and should not) always stop vapor from difusing. A wool sweater for example, is a good choice of insulation and will keep you warm when there is no air movement, but will allow the wind to howl right through it. A wool sweater with a raincoat will keep you warm but hold moisture inside and soak your insulation. A wool sweater with a windbreaker will keep you warm, stop the wind from stealing your heat, yet allow moisture to difuse through it. So think of a windbreaker as an air barrier, and a raincoat as a vapor barrier. That is about as far as I can stretch the human to house analogy, hope it helps.
Since warm air expands, there is more space between its molecules compared to cold air. Water vapour is found in that space. When warm air cools as it passes through your walls, it contracts and squeezes out the moisture, leaving you with condensation. In order to prevent condensation from forming, a vapour barrier should be placed on the warm side of your insulation to stop warm, moist air from condensing on a cold surface inside your wall. In cold climates like Canada, for most of the year the vapour barrier should be on the inside of the insulation. In hot climates like the southern U.S. for example, vapor barrier should be installed on the outside of the insulation, especially where there's air-conditioning involved to prevent condensation and mold. In both cases, the vapour barrier is tasked with preventing warm, humid air from shedding its moisture as it meets a cool surface, no matter which direction it is travelling. The most important thing to realize is that there is no fixed rule regarding vapour barriers. Building practices should always be determined by the climate in which you are building.

How water vapour travels:

There are two main ways moisture will pass through your walls that you should be concerned about — air leakage and vapour diffusion. These are two completely different things, with two completely separate solutions. Vapour diffusion is the process of moisture passing through breathable building materials, like drywall and insulation. Vapour barriers are there to prevent that from happening. Air leakage is due to air pressure differences between indoors and out, which forces air through any holes in your air barrier.

Where the problem arises:

The dewpoint in a wall is the point where the drop in temperature causes air to contract, and water vapour turns to liquid. Since the warmer the air is the more moisture it can hold, where the dewpoint will be in your wall is determined by the difference in temperature from indoor to out, and the amount of moisture in the air (RH - Relative Humidity). The job of both air barriers and vapour barriers is to prevent moisture from forming at that critical point, they just do it in completely different ways.

Vapour barriers

The rule for vapour barrier installation in cold climates is to have it on the interior with at least 2/3rds of your insulation on the outside of the vapour barrier. Air barriers on the other hand can come in the form of house wrap (WRBs), tightly sealed sheathing, insulation that slows airflow, and well-sealed gypsum board (drywall). To explain this further, Gypsum board (drywall) is vapour permeable, but stops air flow. This means water vapour can diffuse through it, but air cannot pass through it. So if you were to have a home with no windows and no vapour barrier but simply a sealed gypsum board box all around, you would have an airtight seal with no moisture carried through by air transport. The key factor here, is that the amount of vapour molecules that will pass through that gypsum board box is insignificant compared to the moisture that will pass through if you cut just one small hole in it and had an air pressure difference.
The difference between air barriers and vapor barriers
The need for a proper air seals in homes is grossly underestimated, and too much faith and focus is put on the vapour barrier. According to the U.S. Department of Energy, "air movement accounts for more than 98% of all water vapor movement in building cavities.” If you think of how a polyethylene vapour barrier is installed, it will be cut, stapled and taped, then have nails and screws put through it to install strapping and drywall, along with breaches due to electrical wires and boxes. In most cases, the vapour barrier will be perforated thousands of times during the building process. But a perforated vapour barrier would actually not be a problem if you have a tight air seal. Like that gypsum board box, the amount of water vapour that can pass through a ripped and torn vapour barrier is insignificant as long as the air seal is intact.

Can a house be too airtight? No it cannot.

Unfortunately, air barriers are really not given the attention they should be in regards to the building envelope. In large residential developments, air barriers are often not even on the radar. Crews come and go, and in the interest of mass production, some standard practices can be detrimental to the performance of the final wall system. A proper air barrier is one of the most important elements of a successful building enclosure, and one of the most overlooked. Given the amount of heat loss due to air transmission and the potential moisture damage from air leaks, air barriers should be getting a lot more attention than they are.

Carbon Monoxide Safety: How to Protect Your Home, Identify Issues, and Respond to Emergencies

 

Carbon monoxide is a tasteless, odorless, invisible gas that occurs naturally through combustion, or, the process of burning. Low exposure to carbon monoxide can cause symptoms similar to the flu. In high doses, exposure to carbon monoxide can be lethal.

Many people who are exposed to carbon monoxide are exposed indoors in their own home. Any appliance that burns fuel indoors could be a potential source for carbon monoxide including gas stoves, clothes dryers, water heaters, furnaces, grills, generators, car engines and fireplaces. Anyone can be affected by carbon monoxide poisoning, but some people are more likely to get sick than others. The elderly, infants, people with heart problems, people with breathing problems and people with anemia are all more likely to experience ill effects from exposure to carbon monoxide. Carbon monoxide has been called the silent killer, because it is completely undetectable by human senses. People who experience carbon monoxide poisoning often have no idea what is happening to them. There are many ways that you can protect yourself and other people in your home from carbon monoxide exposure.

Dangers of Carbon Monoxide

Carbon monoxide is invisible and difficult to detect. Awareness about carbon monoxide poisoning can save lives. Carbon monoxide often enters the home via an appliance that is malfunctioning or an engine that has been left running. People who are exposed to carbon monoxide will experience varying symptoms. Knowing what to look for can help you avoid exposure, and take action when a problem occurs.

Warning Signs in the Home

Carbon Monoxide Building up in Home Although carbon monoxide is itself impossible to smell, hear or see, some warning signs can still be detected. Condensation on the windows, for example, could be an indication of a problem. This occurs because carbon monoxide and water vapor are both byproducts of inefficient combustion. When water vapor appears suddenly and inexplicably in the home, carbon monoxide may be present as well. In some cases, the appliance that is burning fuel inefficiently may produce a hot or stuffy smell. Appliances that leak carbon monoxide may also develop a sooty stain. A pilot light that goes out frequently could be an indication of a problem, as is slow burning fuel. In the case of a fireplace, soot may fall down from the chimney into the firebox. You might also notice lack of an upward draft.

Symptoms of Carbon Monoxide Poisoning

In mild cases, symptoms of carbon monoxide poisoning can seem very flu-like. The severity of the symptoms will depend on the person and also on the level of exposure. Symptoms of mild exposure include:
  • Nausea
  • Dizziness
  • Stomach pain
  • Disorientation
  • Exhaustion
  • Burning eyes
  • Difficulty breathing
Carbon monoxide poisoning is different from flu because of the lack of fever. People start feeling better soon after leaving the area of exposure. Severe cases of poisoning can cause more serious problems. Memory loss, loss of vision and even loss of consciousness are all symptoms of exposure. A feeling of vertigo, chest pains, seizures and a total loss of coordination can all happen. Some victims may even think they're having a heart attack. In the most serious cases, the result may be brain damage, coma or even death.

What to Do When You Suspect Carbon Monoxide Poisoning

What is Carbon Monoxide Poisoning Victims often cannot think clearly once poisoning has set in, which makes self-diagnosis challenging. One of the tell-tale signs is that pets and other people in the house will experience symptoms of poisoning at the same time. In the event of exposure, getting fresh air should be the first priority. Once outside, contact emergency services. Tell the authorities your assumed diagnosis so they can test you for exposure. Do not go back into your house until the air inside has cleared and the environment is safe. If you believe that your exposure is due to a problem with a gas-powered appliance, have your gas company inspect your house and gas line. If someone you love is exposed to carbon monoxide poisoning, call 9-1-1. Be aware that a rescue attempt in a carbon-monoxide rich environment could lead to a dangerous or even fatal level of exposure. Ask emergency responders for next steps before attempting to rescue a loved one yourself.

Carbon Monoxide Detectors

Because symptoms of carbon monoxide poisoning can look like so many other ailments, and because carbon monoxide is basically impossible to detect, carbon monoxide detectors are an essential part of protecting yourself and those in your home from poisoning. Many people have at least one carbon monoxide detector in their home. Here's what you need to know to stay safe.

How Does a Carbon Monoxide Detector Work?

Carbon Monoxide Detector Example A simple reaction causes the alarm to sound. Carbon monoxide detectors come with sensors that measure the parts per million (PPM) of the carbon monoxide (CO) in the atmosphere. If the machine detects high amounts of carbon monoxide in the air, the alarm sounds. The higher the concentration, the faster the alarm will sound. 9 PPM is common in homes, but levels of 10 PPM and over can cause health stress for some higher-risk individuals. A normal healthy adult may be at risk at around 36 PPM and up. Carbon monoxide detectors also come with an LED light that indicates the unit is functioning. You'll be able to tell your carbon monoxide detector is functioning by watching the alarm for the light to flash, or by pushing the test button. If pushing the test button does not cause the alarm to sound, then the batteries may be dead or the unit may need to be replaced. Most detectors need to be replaced every 5 to 7 years. Check your specific unit for an expiration date or a date of manufacture, then replace the unit when the time comes.

How Many Carbon Monoxide Alarms Should I Have? In What Location?

You almost can't have too many carbon monoxide detectors. The Consumer Product Safety Commission recommends putting carbon monoxide detectors in a number of places in your home. Put them outside your bedrooms, in your hallway, in your kitchen, near your furnace and on every floor of your house. If you have an enclosed attached garage, put a detector just inside or near the door to your garage. If you're hard of hearing, make sure carbon monoxide detectors are dispersed so you will hear them from where ever they go off. Here is another resource of general DO's and DONT'S when it comes to carbon monoxide detector placement.

What Type of Carbon Monoxide Detectors Should You Install?

Carbon Monoxide Detector on Ceiling There are multiple types of carbon monoxide detectors. You can choose the type that's right for you, your budget and your household.
  • Battery operated. These are basic carbon monoxide detectors that can be installed easily with a simple screw.
  • Hardwired. Hardwired carbon monoxide detectors are connected to a home's electrical grid; they rely on battery backup when the power goes out.
  • Digital. Digital carbon monoxide detectors show the level of carbon monoxide in the home so homeowners can monitor the level of CO in the air.
  • Smart. Smart carbon monoxide detectors can be connected to a home's wireless network, so levels of CO can be monitored even from a distance.
Many modern homes come with carbon monoxide detectors hard wired into the walls. If your home does not have hardwired detectors, battery operated carbon monoxide detectors will work just as well.

Maintenance

Once the carbon monoxide detectors have been put up, test them monthly and replace their batteries annually. Be sure to check the expiration dates or dates of manufacture when you replace the batteries, to ensure that the detectors are replaced when the time is right. Like smoke detectors, carbon monoxide detectors will chirp when their batteries start to go dead. When the unit detects carbon monoxide, the alarm will sound. No amount of replacing the battery will stop the unit from beeping if there is carbon monoxide in the air. Don't assume that there's a false alarm if the unit goes off.

What to Do When the Carbon Monoxide Detector Goes Off

When a carbon monoxide detector goes off in your home, leave the house calmly. Take everyone in your house outside with you, and if possible, bring your cell phone as well. Once outside, check everyone for signs of possible carbon monoxide poisoning. Contact the authorities to alert them to the problem, and if people from your household are showing signs of a health problem, tell the authorities while you're on the phone. Hopefully emergency personnel will come evaluate your home for possible carbon monoxide leaks. If the authorities are not coming, contact an appliance repair person, plumber, HVAC contractor or someone from the gas company to check on the problem for you. If the carbon monoxide detector goes off and the proper help is unable to find sources of carbon monoxide in your home, the problem may have dissipated or you may have had a false alarm. The following tips will help you avoid false alarms in the future:
  • Relocate your carbon monoxide detectors to an area 10 feet away from sources of humidity and 20 feet away from fossil fuel burning appliances.
  • Replace the batteries in your carbon monoxide detectors to ensure they are functioning properly.
  • Replace the units altogether if you have reason to believe that they're no longer working.

Preventing Carbon Monoxide Poisoning at Home

Sometimes it is not a fuel-burning appliance that causes the problem, but the person operating the appliance. It's very important to use best practices when operating your home's appliances, fixtures and heat sources. Be aware of the things you could do that would potentially put you at risk for carbon monoxide poisoning. The more you know about carbon monoxide and how it is produced, the better.

Things That Cause Carbon Monoxide Buildup

Sources of Carbon Monoxide in Home An array of things can cause carbon monoxide to buildup inside the house. Appliances must burn fuel efficiently or they could produce excessive amounts of carbon monoxide. You can protect yourself by inspecting your home's appliances for indications of a problem and by keeping your appliances in good condition. Gas-Burning Furnace Gas-burning furnaces use combustion to produce heat that keeps your home warm. Inspect your furnace on an annual basis and watch for signs of inefficiency. Take note of the following problems:
  • Yellow flames
  • Soot around the combustion chamber
  • Blocked vents
If your furnace displays any of these symptoms, contact an HVAC professional immediately for a check up and tune up. Gas-Burning Stove Like the furnace, a gas-burning stove should produce blue flames and little or no soot. Using the vent in your kitchen can help keep carbon monoxide levels low when cooking. If there is no vent, or if the vent is not functioning, have that fixed. Avoid setting oversized pots on the flame, and avoid placing foil on the bottom of the oven. Fireplace or Wood-Burning Stove An upward draft in your chimney is required to keep a fire burning efficiently in your home. Pay attention to poor upward draft (your home will become smokey). And only burn seasoned firewood. Have your gas and wood burning appliances inspected on a regular basis, and have your chimney inspected and cleaned yearly. Get a tune up for any fuel-burning appliances that start to behave strangely, produce odd odors, make strange sounds or function less efficiently. Water Heaters Gas burning water heaters are a source of carbon monoxide just like any furnace or stove. Gas burning water heaters rely on a pilot light to produce combustion that heats water in the tank. Gas burning water heaters that are burning inefficiently may produce soot or a yellow-brown byproduct that indicates poor combustion. If you can see the pilot light, look for yellow flames instead of blue. Have your water heater inspected if you notice signs of a problem. Engines Engines of all types produce carbon monoxide. Car engines, generators, power tools and lawn mowers are all common sources of carbon monoxide in the home. Poisoning by carbon monoxide sometimes happens when car owners accidentally leave their cars running. This is becoming more common as a greater number of car owners now use keyless fobs to operate their vehicle. This is an easy mistake to make because modern cars tend to be very quiet, and no key is required to shut off the car. If you're buying a modern car, you can protect yourself from this problem by purchasing a vehicle that has an alarm that will alert you if you leave the car running. Other ways to protect yourself from engine-related carbon monoxide include:
  • Avoid turning on lawn mowers and power tools indoors.
  • Never run a generator indoors; place generators outside at least 20 feet from windows and entryways.

Best Practices and What Not to Do

A lot of homeowners and renters make mistakes that lead to carbon monoxide poisoning because they simply don't know any better. If you own a home or rent an apartment with appliances that burn fuel, or if you keep gasoline on hand in your home, familiarize yourself with these best practices. Gasoline As gasoline evaporates, it produces a number of vapors, including carbon monoxide. You can protect yourself and members of your household by keeping gasoline in an air-tight container away from sources of combustion.
  • Use a gasoline container with a child-proof lid to store gasoline.
  • Keep gasoline away from heat sources and sources of combustion.
  • Never use gasoline to light a fire.
  • Never store gasoline without a lid.
  • If possible, keep gasoline in a detached structure like a shed.
Other Sources of Carbon Monoxide Poisoning In addition to the common sources mentioned above, there are other ways that can cause the build up of carbon monoxide in the home. Fumes from certain paint thinners and other harsh chemicals may contain carbon monoxide. If you're taking on any home improvement projects that involve harsh chemicals, follow all manufacturer instructions that require use in a well-ventilated space. Grills can be a source of carbon monoxide poisoning. Never operate a charcoal or gas grill indoors, even in a garage with the door open. Operate grills outdoors, away from windows in areas where ventilation is good. Even a blocked chimney or a partially closed flue could cause your home to fill with carbon monoxide quickly. Check the flue before lighting a fire in your chimney or wood-burning stove, especially when lighting for the first time at the start of winter or after a long period of time. Never use your fireplace if your chimney is partially blocked by an obstruction. Finally, camping stoves can also be a source of carbon monoxide. Never use a camping stove indoors in a space that is not well ventilated.

Stay Educated, Stay Aware

Changing Battery in Carbon Monoxide Detector Under the right conditions, carbon monoxide poisoning can happen anywhere, in any home. Being aware of the potential danger can help you protect yourself, your loved ones and the people & pets in your household. If you and others in your household become mysteriously ill all at the same time, stop to ask yourself why. Keep carbon monoxide detectors on every floor of your house and in strategic locations. Replace batteries annually, check the expiration dates and replace as needed. If your carbon monoxide detector does go off, don't assume that it's a mistake. Get your family out of the house and work with the authorities to ensure that your house is safe. Many government agencies provide information about carbon monoxide poisoning. When the time comes to buy new carbon monoxide detectors, consider replacing old standard detectors with smart or digital devices, which provide more information about the conditions inside your house. If you have questions about the effects of carbon monoxide poisoning, talk to your doctor. If you're worried about the condition of your appliances, talk to your appliance repair person or contractor. Following these tips could save your life and the life of the people you love.

What Do I Need to Know About Mold?

There are few things that homeowners dread more than mold in the house. You’ve likely heard horror stories about people living with mold infestations that made them seriously ill. Is this just hype, or is there a real danger to having mold in your home? More importantly, what can you do if you find mold growing somewhere in the house?

What Is Mold?

Mold is a broad group of fungi, with thousands of species and subspecies around the world that typically prefer dark and damp habitats. Often fuzzy in appearance (though occasionally slimy or cottony), molds spread across materials and break them down to get the nutrients the mold needs to survive and thrive. Instead of seeds, molds release single-celled spores that in many cases are too small to see with the naked eye; these spores float through the air to land on a variety of surfaces, beginning growth once they find themselves in a suitable habitat. Though molds are made up of a number of individual stalks fibers, a connected clump of mold is considered to be a single living entity.

Types of Mold

There are several common types of mold that you might see around the house. While some of these may not be inherently dangerous, any mold can trigger reactions in anyone with an allergy or sensitivity. The five most common of these molds are:
  • Aspergillus: One of the most common indoor molds, it often appears green, blue-green or gray but can also appear white or even yellow.
  • Cladosporium: A black or green mold that has an appearance like ground pepper, it commonly grows on smooth surfaces like toilets and painted walls but can also grow in fabrics and rugs.
  • Ulocladium: A black mold that grows in wet areas, especially in cracks and corners; it is most common in homes with water damage and active leaks.
  • Aureobasidium: Varying in color from pink to brown or black, this mold most commonly grows behind wallpaper, on painted surfaces and on wood.
  • Stachybortrys: The infamous “black mold”, it features a slimy dark green or black color and thrives in areas that are damp and maintain high humidity for weeks.

Is Mold Actually Dangerous?

While many molds are allergens, most will not cause severe reactions unless you have a mold sensitivity or have other health problems that make you more prone to infection. However, some molds (such as black mold) actually are toxic and can make you very sick if you’re around them for too long. Symptoms of a mold allergy or toxic mold exposure can include a chronic cough, skin rashes, fatigue, difficulty focusing and even pain or infection in your sinuses, eyes and ears.

Mold Testing and Removal

If you suspect that you have mold problems, there are home tests available to help you identify the type of mold in your home. These should only be a first step, however, as they often aren’t enough to definitively show you the scope of your mold problem. Call in an expert to confirm the results of your test or take a scraping of the mold and have it analyzed. Be sure to wear a dust mask or other breathing protection if you aren’t sure what type of mold you’re dealing with until the problem is taken care of. For many mold infestations, getting rid of leaks or other sources of humidity is a great way to slow or even stop mold growth. Mold can cause serious damage over time, however, so you may need professional mold removal and repair services if you can’t get the problem under control early. Is your home in need of some serious mold removal? HomeKeepr can help you find a mold remediator to get the mold out quickly and at a price you can afford. Because we utilize references instead of reviews, you’ll be able to rest assured that the expert you choose can really get the job done.
