Replacing a Cracked Window Pane

Window pane replacement can often be a straightforward home repair project; however, professional assistance can be sought if more extensive damage is present or special tools are needed to complete the job.

Materials

  • New window pane cut to size
  • Glazing compound
  • Glazier’s points
  • Putty knife
  • Caulk

Instructions

  1. Remove the damaged pane: Wear gloves and safety glasses. Use a utility knife to cut around the perimeter of the damaged pane, ensuring the blade does not score the frame. Remove the old window pane by gently prying it loose with a putty knife.
  2. Clean the frame: Remove any remaining pieces of glass or old glazing compound from the window frame using a putty knife. Wipe down the frame with a damp cloth to remove dust and debris.
  3. Apply glazing compound: Apply a bead of glazing compound around the perimeter of the window frame where the new pane will rest. Use a putty knife to smooth the compound.
  4. Set the new pane: Carefully place the new window pane into the frame and press gently to ensure it is securely seated in the glazing compound.
  5. Secure the pane: Drive glazier’s points into the frame around the perimeter of the pane to hold it in place. Use a hammer or a glazier’s point driver.
  6. Apply caulk: Apply a small bead of caulk around the perimeter of the pane where it meets the frame to seal any gaps and prevent water infiltration.
