Bring these measurements to the nearest hardware store or home center and get a piece of stock glass cut to size. Alternatively, you can cut the glass yourself if have the right tools.

After putting the new pane in place, run a small bead of caulking around the edges to make it weatherproof. Install a glazier's pointing on both sides of the frame. This will ensure the pane.

Before applying the putty, make sure to knead it until it's soft and free of lumps. Then, roll it into pencil-size strips. The first strip should be placed to the corner of the frame, working from one corner to the other to ensure it is even and smooth.

Glazier's Points

Take the glazing points out of the rabbets, or the grooves in the sash where the glass sits. If they're hard to chisel out, try placing the hand tool, such as a heat gun to soften them first. When using a heated tool, be sure to not scratch the sash and its railings.

These are essentially small metal triangles which function as "nails" that hold the window in place within the frame of wood. They are buried under a bead of glazing putty, which transforms into a solid molded wedge which holds the window in place and hides the points.

After removing 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 to bare wood surfaces, so that you can paint the frames the same shade. After sanding the wood then apply a layer of flax oil. This will help prolong the life of the frame.
