These measurements can be sent to an hardware or home centers store to get cut a piece of stock glass to the right size. You can cut the glass yourself if you possess the right tools.

After installing the new pane after installing the new pane, put a tiny amount of caulking around the edge to seal it against weather. Install a glazier's pointing on both sides of the frame.

Before applying the putty, knead it thoroughly until it's soft and free of lumps. Roll it into pencil-sized strips. Apply the first strip in the corner of the frame, working from one corner to another to ensure it is even and smooth.

Glazier's Points

Write down the dimensions of the frame. Bring these measurements to a hardware store or home center and have the new pane made slightly smaller than the frame's opening. This will ensure a snug fit and leave room for expansion and contraction.

Insert the new pane into the frame and push firmly with your hands. Then, you can use the point of your chisel or back end of the putty knife to make a tap on the glazier's points as illustrated in Figure 11.

After the glazing compound dries and the glazing compound is dry, you can install the new window sash. First, you need to coat the wood with an even layer of linseed.

Remove the glazing points from the rabbets and the grooves in the sash, where the glass sits. If they're difficult to cut out, try holding an instrument like a heat gun over them to soften them first. When using a heated tool, be careful to not damage the sash and its railings.

Once the old glazing points and putty have been removed, make a bed for the new pane. Roll a piece of glazing compound between your hands, and form it to be around 1/2-inch thick. Then, press it into the rabbets in which the glass will be. The glass should rest against the putty on both sides. If necessary, lightly tap your glass into the rabbet using your thumb.

If the new pane has a crack, you can cover it with a solvent-based glass glue or silicone caulk prior to pressing it into the sash.

After taking off the old pane clean the frame and the wood. Scrape off any paint that has been used, and sand the rabbet grooves in which the glazing points were. Sand them down to clean 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 extend its life.
