Is Your Sealed Window Failing?

Notice how your body starts to break down a little as you get older? Suddenly the elements effect you a lot more then when you were a teenager? The sealing on your windows behaves in a similar way and becomes less effective with time and wear and tear. Here are a few reasons why your sealed windows might be failing you.


With fine wine as the exception, most things tend to break down the older they get. If you’ve noticed your windows are feeling drafty or even letting in some rain water, take a second and think when was the last time they were repaired or replaced? Your window sealing will work best for you if you take care of it and don’t let it grow too old.


Although a window seal’s primary job is to keep out the elements, sometimes overexposure to hard elements can cause the seal to crack. Excessive heavy rain can create a lift in the seal and further rain damage could result in the seal being broken completely. It’s important to notice any leaks and repair them as soon as possible.


Window seals are made tough to prevent deterioration, but sometimes mold is still a concern. Constantly damp environments are breeding grounds for mold. To increase the longevity of your window seal, try to pat down the wet window seals whenever possible, although it’s a difficult task to undertake. Be mindful of mold on your seals because they lower the effectiveness of the seal and might be cause for a repair.


Since the window seal is the barrier between the outdoors to the indoors it bears the brunt of the harsh temperatures. If there is a drastic increase or decrease in temperature, depending on the material, the seal could swell or shrink possibly causing it to become ineffective at its job. Be sure to check if a quick repair is necessary if you feel a draft.


When your windows are installed you may be given a maintenance check list inclusive of proper cleaning products to use on the seal. If the window seals are not maintained properly then it’s only a matter of time before they start to show signs of wear and tear.

Window seals will not last forever and eventually they will start to fail. Rather than breaking the bank to buy replacement windows, contact M&T Glass and have one of our trained professionals to fix the window and make it as good as new.
