How To Repair A Window Seal

by Don Miller

Everything looked and seemed fine when you installed your new window panes but now you have started to see a cloudy film between the panes of glass. This is the first sign that the seal on the window has failed. This is a fairly common problem with double or triple pane windows but it can lead to a loss of insulation, which will end up costing you in the long run. But rest assured, there are several ways for you to repair a window seal and fix the problem.

If the problem is extreme then the easiest way to repair a window seal may be to replace the entire window and start over. This may or may not require the assistance of a professional depending on the kinds of windows that you have. But if you have a regular double pane, double-hung window then it should be pretty easy to do the installation and replacement yourself.

When you choose to repair a window seal this way the first thing you need to do is remove the window. In order to do that you need to remove the trim molding first and then unscrew the window pane from the window sill. Once you have removed the glass then you need to clean away any caulking that remains on the window frame. When you have the window frame clean then you need to put down new caulking and place the window securely back in the frame. Now you need to screw the window into place and be sure that you seal any hole in order to complete the repair. The final step is to replace the trim molding and everything should be repaired and in order.

Another option when you repair a window seal is to replace the glass. Sometimes the problem with the seal is that the glass needs to be reglazed and that will solve the clouding problems. Unfortunately this is not a solution that you can do yourself apart from taking the window panes out of the window. You will need to take the panes to a professional to have them reglazed if you choose to repair a window seal this way.

Probably the simplest way to repair a window seal is to use a specialty tool to fix the seal itself. The first thing that you must do is to puncture the seal, install a valve that will get rid of the moisture between the window panes, and then resealing all the leaks in the seal. Usually this method to repair a window seal is normally done by a professional, it is possible to do it yourself.

The final option when you repair a window seal if to simply not do anything. If you live in a mild climate that does not usually experience temperature extremes then it likely won’t have any impact on your home’s insulation. These types of windows are made for climates with extreme temperatures, if that doesn’t apply to your home then you might want to rethink your plan to repair a window seal.
