One question I often get asked is why the seals on windows and doors break.

Here's why. Windows and doors are subjected to harsh elements like extreme temperatures, sunlight, ultraviolet rays, wind, rain, ice and snow. This means that the window glass is constantly expanding and contracting, much like an accordion. The positive and negative forces pull the window glass away from the spacer when it's cold and they crush the spacer when it's hot. We call it solar pumping.

Ultraviolet light combines with the heat and cold to gradually weaken the bonding agents that hold the window glass to the spacer. Eventually a pinhole-sized break between the window glass and spacer occurs. Humidity is pulled in through the broken seal in between the two panes of window glass, and it looks like a 'fog' that can't be wiped off.

Replacing failed window seals with new window glass restores the insulating value.
The moist air inside a failed unit isn't a good insulator, whereas a new unit with dry air is a very effective insulator and saves energy costs.

If you or people you know are in need of window or patio door repair or replacement, I encourage you to check out more videos on our web site www.windowreplacementrepair.com or give us a call at 314.966.2666.
