Replacing broken glass in a single-pane window with a wood frame is neither difficult nor time consuming. Wear heavy gloves and safety glasses or goggles.
Difficulty: Easy
Time Required: 1-2 hours

Here's How:

  1. Working from the outside, carefully remove all pieces of loose glass. With a putty knife, chip away at the dried glazing compound around the edges of the pane. If the compound won’t budge, try heating it with a hair dryer or heat gun. Alternatively, cover it with some linseed oil and let the oil soak in for at least an hour. If the putty knife doesn’t seem strong enough, try a small chisel.

  2. Pry out the small metal glazier’s points holding the glass against the frame. Remove all dried putty and paint from the frame, then brush it clean. Paint any bare wood with primer.

  3. Measure the width and height of the opening very carefully. Subtract 1/8 inch from each dimension. Measure the thickness of the glass, then head to the glass store for a replacement pane.

  4. Once the primer has dried, make a thin rope (about 1/4-inch thick) of glazing compound and press it into place around the frame.

  5. Set the replacement glass into the frame. Press carefully around the edges. Secure the glass with new glazing points. Push them into the wood with a putty knife, spaced about every 4 to 6 inches. Be careful not to apply pressure to the glass while doing this.

  6. Apply more glazing compound around the edges, then smooth it with a putty knife held at a 35-degree angle.

  7. Let the putty dry for at least a week, then prime and paint it to match the rest of the window frame.
