5 Common Signs of Window Seal Failure

Windows play a significant role in your home’s energy efficiency. They help keep your living space cool in summer and warm in winter. A common issue that can compromise their energy-saving capabilities is seal failure. 

A leading installer of windows and patio doors shares five common signs of failed window seals. 

1. Drafts

Windows with failed seals will allow outdoor air to enter your living space, which can cause discomfort. To confirm the presence of drafts, dampen one of your hands and hold it up near the window. If you feel cold air touching your skin, you could be dealing with window seal failure. 

2. Condensation Between Panes

Condensation on windows isn’t necessarily something you should worry about. It occurs due to a significant difference between indoor and outdoor temperatures. The fogging should naturally go away on its own. If it doesn’t, you might be facing a more serious issue. If you can’t wipe the condensation off the window glass, it can indicate seal failure. 

3. Water Damage 

Do your windows have dark stains or streaks? Do the areas around them have peeling or bubbling paint? These are the results of excessive exposure to moisture. If you see debris stuck inside the glass, it means grime entered through the compromised seals. Have affected windows replaced immediately to avoid further damage to your home. At Renewal by Andersen® of Central Pennsylvania, we install high-quality replacement windows and hinged French doors. 

4. Distortion

Multipane windows usually have an inert gas between their panes. When their seals fail, the gas will escape, which can cause the glass to bow in the middle. To determine if your window has distorted glass, stand a few feet away from it and check your reflection. If the image you see looks warped, seal failure has occurred. 

5. Increased Energy Costs

Have your energy costs been increasing lately? Your windows could be to blame for this issue. Damaged seals will allow warm outdoor air into your home, overworking your HVAC system.
