How to Fix Window Seal Failure
9/10/2014 3:00:00 PM
Do you think your window seal has failed, but aren’t sure? The most surefire way to know that your window has experienced seal failure is if you see condensation in between the panes of glass. If you have double or triple pane windows, window seals are generally very reliable, but pressure washing, scraping, or sanding your windows, or even just time itself, can cause window seals to fail.
When this happens, what should you do and how should you fix it?
What to Do When Your Window Seal Fails
Just how serious is window seal failure? Fortunately, a broken window seal is not a serious issue in most cases. While window seal failure removes much of the energy saving features found with double or triple pane windows, it does not negatively impact the function or look of the window aside from the occasional presence of window condensation.
Have the Seal Fixed
If your window is leaking, you can sometimes have a specialist replace the seal, but keep in mind that this will not replace the insulating gas that escaped. If energy savings from every window is important to you, then you will have to replace the window. Having the seal replaced, however, is still an environmentally friendly option, as it keeps an otherwise perfectly good window out of the landfill.
Leave the Window as It Is
A broken seal does not always warrant any immediate action. If you live in a relatively mild climate without high humidity levels, then fixing the seal is really of little value to you. You may occasionally experience some moisture buildup, but you will not see any significant impact on your energy bills if a single window experiences seal failure.
Replace the Window
If you live in a climate with extreme temperatures or high humidity, replacing the window may be your best bet. Climates with high humidity levels will often leave windows with broken seals with constant condensation, ruining the aesthetic of the window and diminishing the view. In climate zones with extreme temperatures—hot or cold—you will see more benefit from replacing the window with a new one. The insulated glass will protect your home from hot and cold spots, keeping your home more comfortable and reducing energy bills. This is particularly important in small rooms with only one window. A broken window seal in these rooms can result in uncomfortable conditions when it is very hot or cold outside.
