How to Repair Soundproof Windows

If your soundproof windows are new, they probably won't need repairs for several years. Older windows can suffer from wear and tear, however, and any window can have an unfortunate meeting with a baseball. Here are a few handy tips on repairing soundproof windows that may help you with your other windows as well.

Replacing Cracked Glass in Soundproof Windows

Removing the broken glass from the frame is the first step. For extra-large soundproof windows, it's recommended that you remove the window frame itself and set it down on a flat surface before attempting removal. Don't forget to wear protective work gloves so you don't catch your skin on an edge. Next, remove the old putty and the glazier's points and get ready to apply a very thin putty layer as primer. With older frames, you need a coating of linseed oil before you put the putty on.

Insert the new soundproof window glass carefully and secure it with new glazier's points. Next, roll your putty into pencil-thick strips and apply it around the perimeter of the new glass, smoothing it out with a putty knife or glazing tool. Sandpaper can help with rough spots once the putty dries.

Unsticking Uncooperative Soundproof Windows

If your soundproof windows have been accidentally sealed with paint, break the paint seal with a paint scraper or putty knife. Should the window still stick after the exterior seal is broken, there may be paint on the tracks. Slip a thin block of scrap wood against the window sash and gently tap it with a hammer to work the window away from the frame. Make sure to clean, sand, and lubricate the tracks once you get the window open. If your soundproof windows stay stuck after all this, it may be humidity, uneven house settling, or poor window construction. At this point, it's best to call a carpenter.
