Home Window Repair How To Repair A Broken Window Without Replacing The Frame

Dec 27

Home windows are an essential part of many homes, providing natural light and airflow. However, older and poorly maintained windows are vulnerable to deterioration and can be subject to damage caused by weather, insects and other factors. Fortunately, it is possible to home window repair without replacing the entire window frame. This project requires a little bit of work, but it can be accomplished by a do-it-yourselfer. Before starting, ensure that you have thick cut-proof gloves and safety glasses to protect yourself from glass shards.

To begin repairing a broken window, start by taping off any cracks or areas where the glass has shattered. This prevents the broken glass from shattering into smaller pieces and helps hold the glass in place as you work to remove it. Once the area is taped off, it's time to remove the old glass pane. Put on your gloves and safety glasses and use a utility knife to carefully break the glazing off the frame. Then you can remove the rest of the glass by prying it out with a flat pry bar. Once you have removed the glass, remove the old window putty and metal glazing points. A heat gun can help loosen the putty, and a pull-type paint scraper or a hammer can be used to break up the glazing. Once the old glazing is gone, make sure the grooves are smooth and ready for a new glass pane by using a file or a dremel tool. Then apply a silicone caulk to the grooves and press your new glass pane in.

When you're finished, you should have a nice new replacement window that is secure within the frame and that operates smoothly. If you have problems opening or closing the sash, try lubricating the track the sash travels on with beeswax or candle wax. For more serious problems, consider consulting a professional for advice and help.

Depending on the severity of the damage, you may need to replace the wood around the window frame. In most cases, if the area of rot is small, epoxy wood filler can be used to repair it. However, if the rot is deep or extensive, it will require a more thorough repair.

If the upper or lower sash is stuck in one position, it's often because the sash weights have broken or are out of balance. This is an easy fix for most do-it-yourselfers, requiring only a trip to the hardware store for sash weights or springs. The sash can also become stuck due to paint bridging the sash and frame together, or from being bent by a heavy wind or snowfall. In either case, a simple fix is to buy a rot-free drip cap at a home center and nail it into place over the existing hole in the frame. This should keep the rain out for good.
