According to a window replacement expert, checking for failed window seals is a task you should take seriously. Window seals are designed to keep out the elements while also keeping warm air inside during cold weather. When these seals fail, it compromises the integrity of your home’s energy efficiency and can lead to more serious issues such as water damage and mold growth.
Reasons Why Window Seals May Fail
There are several reasons why window seals may fail.
Poor Installation. Poor installation often occurs when a contractor has cut corners while installing new windows. In some cases, contractors may not properly secure the sealant around each side of the frame correctly resulting in gaps that air can escape through.
Age. With time, seals can become brittle due to UV exposure. This weakens their adhesive qualities leading them to crumble or fall out of place when enough pressure is applied to them.
High Heat or Cold. Extreme heat or cold could cause expansion and contraction in materials used for making sealants or even the frames themselves which can cause sealants to fall apart.
How To Tell If Your Window Seals Have Failed
Not sure if the seals on your windows have failed? Here’s what to do:
Look for Drafts. One way to tell if your window seals have failed is by looking for drafts around the edges of each window frame. Often you will feel a wisp of cool/warm air coming through depending on the season outside even after the window has been firmly closed shut.
Check for Moisture. You should check for moisture buildup around corner points between frames. This could signify an underlying problem with its current state like a broken sealant.
Inspect Glass. You also want to inspect the glass itself to see whether any fogginess has developed around the edges that would suggest moisture penetration somewhere. This means the sealing hasn’t worked correctly, allowing outside elements to get indoors easily.
How To Repair Your Window Seals
If the issue is not too severe, a simple cleaning and re-caulking job could suffice. This involves using a putty knife to remove the old sealant from the area before applying a new one. It’s important to make sure surfaces are cleaned properly beforehand in order for a fresh bond to form securely without any further issues arising afterward.
If the issue is more serious and the sealant has failed completely, it may be necessary to replace the windows altogether.
