Mike Holmes: Assess your windows now, before we get deep into the winter seasonReed Herman
But one other important function is their ability to keep your home from leaking its treated, comfortable air into the outdoors. Some windows will be much better at this than others. Whenever you’re planning upgrades for your home, I always say to focus on your building envelope first. By working on the outside FIRST, you’re taking steps to protect what’s inside your home – and make it more energy efficient, too.
This is good time of year to assess your windows, before we get deep into the winter season, and your HVAC has to kick in to overdrive. Here are some of the signs you’re ready for some new windows.
They’re difficult to operate
It shouldn’t take all your strength just to open and close your windows to let some air in. If they don’t work like they used to, such as not opening smoothly, or getting stuck in the track, you’re likely ready for new windows.
For true accessibility, windows should only require one hand to operate. Casement and awning windows that open and close with a crank are easiest to use for any homeowner, and you don’t risk accidentally slamming the windows shut. All windows should also come with good locks for added security.
They start to ‘cry’
When the temperature outdoors stats to dip and your heat kicks in, do your windows develop condensation? Don’t whip out the tissues just yet – but if this is a recurring problem, it could be indicative of bad windows. Don’t rip out the windows just yet because there are a few potential causes of weeping windows.
Condensation on windows can be caused by a lack of ventilation in the house. If a house is very well sealed, and lacks mechanical ventilation such as an HRV or ERV, or even a bathroom ceiling fan, humidity levels can get too high. Cooking, showering and doing laundry all add humidity to the home. Ideally, relative humidity in the home should be kept between 35% and 45%.
First, turn down your humidifier by about 10 percent and see if you still get that buildup. Take a look at the seal around your windows, and replace old, worn, or missing caulking as necessary. It could solve the issue completely.
If the condensation appears between panes of the window, odds are the airtight seal meant to stop heat transfer is broken, and it’s time to replace them with new windows. If you’re totally stumped over the cause – a home inspector can help you find the source of your moisture issues.
They have visible damage
Your windows are constantly exposed to whatever Mother Nature can throw at it. Freezing rain, ice, sleet, high winds, and even UV rays can start to affect the health of your windows. Look out for things like cracks in the window glass, or visible signs of water damage. Even the best windows and frames can eventually submit to the elements. Check your frames for instances of warping, mould and rot. If they’re starting to show major signs of damage, it’s time for new windows.
Don’t underestimate the importance of curb appeal when it comes to selling your home in the future. Not only does adding new windows add monetary value to your home by making it more energy efficient (not to mention cheaper to heat) – good looking windows can also wow potential buyers, making your home sell that much more quickly.
They’re just plain old
Finally, old windows just don’t do the job the newer, more energy efficient models do. If your windows are seriously old, you might be looking at single pane units instead of double or triple paned glass.
These single paned windows don’t offer any insulation or soundproofing, and are totally energy inefficient. That means your HVAC system is going to have to work that much harder to keep your home at a comfortable temperature. And you’ll be seeing that effort on your monthly energy bills. Think of all that extra money and energy you’re throwing down the drain with inefficient units. Investing in new windows will offer serious long-term savings on your energy bills.
