Sliding windows are the most common and cost-effective option, as their sashes slide along metal tracks on the top and bottom of the window frame. But if the windows are not functioning properly, the tracks can cause more extensive problems. In these cases, the best way to fix your window is to hire a professional to fix the issue.
The first step in window repair is to measure the size of the broken window pane. Most home improvement stores will cut the glass to the correct size for your windows. If you don't know how to measure your window, you can cut a large sheet of glass to fit your window. The new glass should be 1/16" shorter on all sides. When setting the new pane in place, test it first to make sure it fits properly. If the damaged window has a silicone gasket, you will need double-sided foam tape or silicone.
