As the cold air sets in during the fall season, it’s important to look ahead to the coming winter months, and make sure that your home is prepared. Common culprits of heat loss include windows and doors, so knowing when your windows may be underperforming is a helpful tool to keep energy costs down when the heater kicks on.

If you want to test how your windows are doing, the easiest way is to run your hand along the edges of your windows on a cold day. If you notice cold air running through the window, it might be a sign that the window or the seal around the frame isn’t performing well. Another helpful indicator is condensation within the glass panes of the window, which signifies that the insulating seal of the window isn’t up to standard. An important factor to note is that a cold window doesn’t necessarily mean that the window needs to be replaced, and the most crucial signs are cold drafts of air and condensation within the glass panes.
