Several signs could indicate window seal failure. As your trusted window replacement contractor, we share the three main signs here.

1. Condensation

You may have a broken seal on your windows if you see condensation inside the window panes. Clean your window thoroughly to ensure that there is no condensation or smudges on the outside of the glass. When you’re certain that your window is completely clean on the inside and outside, check for foggy patches again. If you still see condensation at this point, it means that moisture is trapped between the panes and you have a broken seal.

2. Glass Distortion

You can also check for glass distortion to know if your window seal has failed. If your window is filled with argon or krypton gas, the gas that leaks out is not replaced with air. This can cause the middle of your window to bow. To check for glass distortion, stand outside away from the window and compare your reflection between the window you suspect has a broken seal and the other windows in your home. If your reflection appears more warped in one window than the others, you most likely have a broken seal.

3. The Ice Test

Sometimes, you may have a broken seal but no visible condensation on the window. In this case, you can use a piece of ice to check for a broken seal. Make sure you clean both sides of your window. Then, for a few seconds, rub a piece of ice on a small area of the window. Remove the ice and clean the window once more. If you can still see moisture on the window after wiping both sides, you have a broken window seal.

Wind Damage and Thermal Expansion 

Strong winds, in conjunction with thermal expansion and pumping, can cause window seal failure. Thermal expansion happens when the gas trapped between the glass panes of multi-pane windows—and other window components—expand and contract as temperatures increase and decrease respectively. This results in the cycling of pressures within the windows, also known as solar or thermal pumping. Over time, repeated thermal pumping can weaken the seal on window glass. And if your windows are exposed to gale-force winds, their sealing might even fail. 

Important note: Window seal failure can reduce your window’s performance. If the window sealing is damaged, the trapped argon or krypton gas—which is responsible for preventing heat transfer—will be able to escape, lowering your window’s overall energy efficiency. That’s why it’s highly recommended that you replace damaged windows with an energy-efficient window replacement. 

The Warning Signs of Window Seal Failure 

How can you tell if your windows’ sealing has been damaged? Here are the warning signs to keep an eye out for: 

• Foggy glass – Moisture might infiltrate the space between the panes of damaged windows, fogging up the glass. 
• Glass distortions – Window leaks can cause sections of the window pane to collapse, creating distortions in the glass.

One more thing: To make sure your window is installed properly, only reputable window installers should handle their installation.
