Studies conducted by the Environmental Protection Agency have shown that a home can lose 10%-15% of its winter efficiency through its windows. In order to get ready for the coming cold, consumers should take the time to determine if their windows are in top shape for the coming chill. Here are some ideas for how to get started.
Know what you have. Perhaps the most basic step is to find out what type of material makes up your current windows. Wood and vinyl windows expand and contract with the changing seasons and you should anticipate some drafting within 7-10 years of installation. This includes windows made from composite materials that combine wood and vinyl. Since age is a main factor in the deterioration of your windows, identify through your homeowners records when the windows were installed.
Perform a draft test. Take a close look at your windows and see if any cracking or holes are visible. Sometimes compromised windows can be hard to detect. A licensed contractor can perform a blower test for you to confirm any drafting. Beware of contractors who provide this service for free—they are more likely to provide you with biased information in the hopes of replacing your windows.
You can also perform a basic draft test on your own by holding a tissue or lit candle to the window frame on a windy day. If the tissue moves or if the candle flickers, you have drafting.
Consider replacing. While there are a couple of quick fixes you can use to patch up drafty spots on a window, if you want to save money long term, you should consider looking into replacement windows. Find a contractor that can speak to you honestly about all of the different window materials available. Ideally, they should provide options for several materials. Beware of a contractor who sells only one type of material or won’t discuss the benefits of other materials. Each type of has its benefits and drawbacks. Make sure you are well informed in your purchase.
