How to Replace a Windowpane in a Wooden Window Frame
- 1). Put on safety glasses and work gloves before you begin the replacement process. It's also a good idea to place a tarp on the inside floor and outside ground to catch debris, such as broken glass that may fall out.
- 2). Walk to the outside of the window and place a ladder near it, if needed, so you can access it easily. Examine the perimeter of the glass where a thin layer of putty exists. Plug in a heat gun and hold it 1 inch away from the putty for five to 10 seconds. Continue working your way around the perimeter of the window glass.
- 3). Scrape the softened putty off of the entire perimeter using a painter's tool.
- 4). Push the glass pane out from the inside of the home so that it falls to the outside. If the pane is badly cracked, tap it with a hammer from the inside to force the pieces out of the frame. If needed, work any remaining shards loose with a pair of needle nose pliers.
- 5). Look into the bottom edge of the glass to see if there are small metal points. If so, grasp them with the needle nose pliers and pull them out.
- 6). Scrape the window frame with a paint scraper to remove all paint. Then sand the frame with a fine-grit sandpaper until no more paint remains.
- 7). Paint primer onto all areas of the wooden frame using a paint brush and allow it to dry completely.
- 8). Insert the new piece of glass into the wooden frame. Open a tub of glazing compound and scoop up 1/8 cup in your bare hands. Knead it until the putty is warm and roll it into a 1/4 inch strand before pressing it into the area where the frame meets the glass. Place a new metal glazier's point at the center of each side of the glass and press it into the wood frame using a putty knife.
- 9). Scoop out more putty and roll it into a 3/4 inch diameter strand. Press it into the perimeter edge of the window the glass just as before.

Hold a putty knife at a 45-degree angle and run it all the way around the perimeter of the glass to smooth the glazing putty and scrape off the excess.
