Take these measurements to an hardware store or home center, replace Window pane and have a piece of stock glass cut to size. You can also cut the glass yourself if have the tools you need.

After putting in the new pane After installing the new pane, apply a small amount of caulking along the edge to ensure it is weatherproof. Then, you can install a glazier's pointing on each side of the frame to hold the pane in the right place.

Measure the empty frame's dimensions and note down precise measurements. Bring these measurements to a hardware store or a home center and have the new pane cut slightly smaller than the frame's opening. This will ensure a secure fit and will allow room for expansion and contraction.

Place the new pane in the frame and push firmly with your hands. Utilize the point of the chisel or the edge of the putty blade to tap the glazier's points as illustrated in Figure 11. The glazier's point should be aligned with the top edge of your pane, and the shoulders raised should be just below the lip.

After the sash has been re-installed then, apply a new silicone caulk to the glass to ensure that it will not leak or change color as time passes.

Take the glazing points out of the rabbets, or the grooves in the sash that the glass is. If they are hard to chisel, use a hand tool such as a heating gun over them to allow them to soften before.

After taking off the old pane clean the frame and the wood. Scrape away any paint and sand down the rabbet grooves, where the glazing points used to be. Sand them down to bare wooden surfaces so you can paint the frames with the same shade. After sanding the wood, apply a layer of flax oil. This will help extend its life.

The next step is to measure the dimensions of the window opening. You will need to measure the horizontal and vertical dimensions of the entire opening as well as the thickness.
