How to Replace the Glass in a Door

Broken glass in a door is not only unattractive to look at, but it can be dangerous if it falls out when someone uses the door. Fixing broken glass in a door seems more complicated than it is. The project should take less than two hours.

Replace the Glass in a Door

Measure the frame of the broken window. Measure from the outside edge of the frame. Subtract about 1/8 inch from the length and width measurements to account for expansion.

Have a glass store cut your new glass to size. Consider replacing all broken glass with safety glass.

Remove the wooden stops that hold the glass in the door using the stiff putty knife as a prying tool.

Gently remove the broken glass pane.

Use the stiff putty knife to scrape off the old glazing compound.

Using a caulk gun, run a bead of new glazing compound around the inside of the window frame. You will run the glazing compound bead just like you would run a caulk bead.

Press the new window glass into the window frame, sticking it into the bead of window glazing.

Use a few of the glazing points to hold the window in place. One or two glazing points per window edge will be plenty. Tap them in with a hammer.

Replace the wooden stops, nailing them in with a hammer and wire brads

Use a hammer and a nail set to countersink the wire brads.

Things You Will Need

  • New glass pane
  • Stiff-blade putty knife
  • Window glazing
  • Glazing points
  • Wire brads
  • Nail set
  • Hammer
  • Tape measure


  • The wooden stops are strips of wood running around the perimeter of the window. Hold the glass as you remove the last stop to prevent the glass from falling. Glazing compound looks like caulk and comes in the same kind of tube as caulk.
