Glass repair is a good beginning DIY project, if you have the right tools. The most important part of repairing broken glass is to avoid cutting yourself on the glass's sharp edges. Provided that you wear protective gloves, this process can be relatively easy even if you're a beginning DIYer. 

Gather Your Materials

You'll need the following materials to replace the broken window in your wooden frame. These materials are generally available for sale at home improvement centers and hardware stores, but you may need to special order the glass if the pane is an unusual size.

  • 5-in-1 painter's tool
  • Measuring tape
  • Replacement glass piece
  • Primer
  • Paintbrush
  • Push points
  • Glazing putty
  • Paint

Step 1: Remove the old glazing putty.

The old glass will be held in the window with a product called glazing putty. Glazing putty fits around the piece of glass and fills in the cracks between the glass and the wood. It's similar to caulk, but once it's hardened, it can be much more brittle. Use the pointed edge of the 5-in-1 tool to chip away the old glazing putty until the bare edges of the glass is exposed. 

Step 2: Pull out the old push points and remove the glass.

Use the 5-in-1 tool to pull out the old push points that are holding the glass in place. Remove the pieces of glass from the frame as the push points are removed. 

Step 3: Measure the opening in the window frame and buy replacement glass. 

Measure and record the size of the opening in the window frame. When you buy the replacement glass from the glass supplier or hardware store, order a piece of glass that is slightly smaller than the opening in the window to ensure that the glass fits inside the frame.

Step 4: Prime the bare wood on the window.

Primer will help protect the wooden window frame over time. Paint any exposed bare wood with primer to ensure that the wood is sealed off from moisture and condensation. 

Step 5: Put the new glass piece in place. 

Fit the new glass piece into the frame. Use the edge of the 5-in-1 tool to press the push points into the wood and hold the glass in place. 

Step 6: Apply new glazing putty.

Glazing putty goes on like caulk. Use the glazing putty gun to apply the glazing putty around the edge of the glass. Put on just enough glazing putty so that it covers the push points and holds the glass in place. 

Step 7: Paint the glazing putty.

Wait until the glazing putty is dry and then paint it to match the surrounding window frame and the rest of the house. 

When this is all done, the glass in your window should look as if it had never been broken at all. If you're not up for this task, contact a reputable window repair or glass repair company in your area.
