How to Repair Broken Glass Window Panes

By: Danny Lipford

When replacing a broken or cracked glass window pane in your home, be sure to wear protective gloves. Here’s how to go about it:

  1. Use a utility knife, scraper, chisel, or 5-in-1 painter’s tool to remove the old glazing and metal fasteners around the broken pane.
  2. Carefully remove the broken pieces of glass.
  3. Measure the opening for the glass, and subtract 1/8” from the height and width for an easy fit.
  4. Cut the glass using a straight edge and glass cutter, or have it cut for you at a home center or hardware store.
  5. Clean and prime the bare wood around the window and allow to dry.
  6. Set the glass pane in the opening.
  7. Hold the glass in place with push or glazier’s points pressed into the frame on each side of the frame.
  8. Fill the opening between glass and frame with glazing putty.
  9. Allow the putty to dry before priming and painting over it.

    The video is nice, very informative. To ensure easy and safe removal of the broken glass pane, tape off the remaining glass with painter’s tape.

    Of all times to wear safety glasses this would be the one.

    Thanks for the tips. My son and his friends just put a hole in my back window playing with their remote control planes. I was thinking of doing it myself but I do not know if I am quite handy enough. I think you explained it simply enough but I still doubt by ability to fix it myself. Especially if I have to cut the glass. I will have someone come out and take a look at it.

    Thanks for the video, and for giving step-by-step instructions! If one of my window panes broke, I’d definitely let a local hardware or specialty store cut the new glass. However, your tips to remove the glass and to take off 1/8″ while measuring should come in handy, since I should be able to do that myself. Thanks again.

    I’ve replaces a single pane of glass in my old windows using glazing compounds, etc. After watching a video or two, I did not find it too difficult, just tedious from lack of experience. When we recently needed to replace a pane on our old front door, I hired a professional as I had not worked with wood stops before. Now that I’ve seen that procedure first-hand, I would suggest that the wood stops and the glass be removed from the side of the door on the inside of the house. It would eliminate/minimize any minor scrapes on the exterior of the door, eliminate the need for repainting the exterior. At least in my case, the interior is covered with a lace curtain, making any potential scrapes less noticeable than on the front of the door. Just an observation.
