How to Repair Broken Glass Window Panes

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.
