Take measurements of the width and height of the opening in the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to a hardware or home center store to have cut a piece of glass stock to the proper size. Alternately, you can cut the glass yourself if have the tools you need.

After installing the glass After installing the glass, apply a small amount of caulking on the edges. This will make the glass weatherproof. Install a glazier’s point on both sides of the frame.

Before applying the putty to the surface, you must knead it thoroughly until it is soft and free from lumps. Then you can roll it into pencil-sized strips. The first strip should be placed to the corner of the frame, working from one corner to the other to ensure it is smooth and even.

Glazier's Points

Place the new pane in the frame and push it in place with your hand. Then use the point of your chisel or back end of the putty knife to make a tap on the glazier's facets, as illustrated in Figure 11. The glazier's point should be in line with the top edge of the pane and the raised shoulders should be just below that lip.

Apply a thin layer of glazing compound on the rabbet grooves as well as the edges of new glass. This will seal and protect the edges. Let it dry completely and cure.

Once the glazing compound has dried 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.

After removing the old pane, clean the frame and wood. Scrape off any paint and sand down the rabbet grooves where the glazing points used to be. They should be sanded to bare wood, to allow you to paint them the same shade as the rest of the frame. After sanding, apply a layer of flax oil to the bare wood to help extend its lifespan.

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