Make sure the window frame is ready to accommodate the new pane once you have removed the old putty. Find the width and the height of the opening for the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to the nearest hardware store or home center, and find a piece glass cut to size. You can also cut the glass by yourself if you possess the right tools.

After installing the new pane After installing the new pane, apply a small amount of caulking around the edge to make it weatherproof.

Before applying the putty to the surface, you must knead it thoroughly until it becomes soft and free from lumps. Then, roll it into pencil-size strips. The first strip should be placed to the corner of the frame, moving from one corner to the next so that it is even and smooth.

Note down the exact dimensions of the frame. These measurements can be taken to a home center or hardware store, and the new pane will be cut a bit smaller. This will ensure that the pane fits snugly and allows for expansion and contraction.

Place the new pane into the frame and push it in with your hands. Utilize the chisel's point or the back of the putty knife to tap in the glazier's points as shown in Figure 11. The glazier's points should sit aligned with the top edge of your pane, and the shoulders raised should be just below that lip.

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

This will prevent the new putty from soaking up the moisture and deteriorating and cracking over time. Use a brush to apply this coat, or the point of the putty blade.

The glass is held into the position with a tiny metal clip, referred to as the glazier's point, and putty. This compound is also known as glazing compound. Before you install a new pane, first take out the old one and clean up the area with a rag and a pull-type paint scraper or the wood chisel. Wear safety glasses and gloves when working.

Take the glazing points out of the rabbets, or the grooves in the sash where the glass sits. If they are hard to cut, place an instrument such as a heatgun over them for a few minutes to soften them. When using a heat tool, make sure to not damage the sash's railings and sash.

Prepare a bed for your new pane after removing the old glaze and putty. Roll a rope made of glazing compound between your fingers, and make it about 1/2 inch thick.
