Windows are crucial in keeping your home energy-efficient, comfortable and looking its best. That’s why watching for any signs your old window seals may have failed is important. In this blog post, we discuss the causes of window seal failure, the signs to look out for and when to consult professional home remodeling contractors.

Causes of Window Seal Failure
There are several reasons why window seals fail over time. One common cause is age or natural wear and tear. As windows age, the seals can deteriorate, eventually leading to seal failure. Poor installation is another potential cause. If your windows were not installed correctly, the seals might not have been completely secure. Lastly, exposure to extreme temperature changes can cause the sealant to expand and contract, which may weaken or break the seal over time.
Signs of Window Seal Failure
So how can you tell if your window seals have failed? Here are some signs to watch for:
- Condensation between panes: If you notice moisture or condensation between the panes of your double- or triple-pane windows, it could be an indicator that the seals have failed, allowing moist air to enter the space between the panes.
- Fogging or cloudiness on the glass: Similar to condensation, fogging or a cloudy appearance on the inside of the window panes could indicate that the seals have failed and need attention.
- Drafts near the window: If you feel a draft coming from your windows even when they are closed, it may be due to failed seals allowing outside air to enter your home.
- Distorted or warped glass: Failed seals can also cause the glass to distort or warp, as the pressure between the panes is no longer regulated properly.
The Impact of Failed Window Seals
Failed window seals can have a negative impact on your home. They can increase energy bills since the windows no longer provide proper insulation. Reduced home comfort is another consequence as drafts can make your living space feel colder or hotter than desired. Lastly, failed seals can cause damage to surrounding walls and flooring due to moisture infiltration.
Schedule a Professional Window Inspection
If you suspect your window seals have failed, it’s important to consult window replacement companies for an evaluation. Not only can they determine the extent of the problem, but they can also give you repair or replacement options, depending on the severity of the issue.
