Bring these measurements to a hardware store or home center and have a piece of stock glass cut to size. You can also cut the glass by yourself if you have the appropriate tools.

After putting in the new pane, run a small bead of caulking around the edges to ensure it is weatherproof. Install a glazier’s point on both sides of the frame. This will help secure the pane. The points should not be so tight as to cause friction between the sash and frame, but they also should not be too loose.

Before applying the putty, make sure to knead it until it is smooth and free of lumps. Then, roll it into pencil-size strips. Apply the first strip in the corner of the frame, moving from one corner to the other to ensure it is even and smooth.

Glazier's Points

The glazier’s points are small triangular pieces of steel that help secure the glass into the window frame without causing damage to the delicate surface. Learning how to use these hidden little helpers is easy and can save you money on a professional installation or the cost of buying new glass.

Place the new window in the frame and [Redirect-302] push it into the frame with your hand. Then use the point of your chisel, or the back end of the putty knife to pierce the glazier's points as shown in Figure 11. When you're done, they should be level with the top edge of the pane, and the raised shoulders of the points should be just below the rabbet's lip. groove.

Apply a thin bead of glazing compound on the edges of the new glass and into the rabbet grooves to seal and protect them. Let it dry completely and cure.

Install the new window sash after the glazing compound has dried. The first step is to coat the wood with a heavy coat of Linseed oil. This will stop the new putty from taking in the moisture and deteriorating and cracking over time. Apply the coating using a brush this coat, or the point of the blade. Then use the chisel that is on the back of the tool or the back of the putty handle to gently hammer the new sash or glazier's tip into the grooves of the rabbet.

Putty

A baseball that is thrown or an unintentional rock, or a falling branch can cause a window to break or crack.

This compound is also known as glazing compound. Before installing a new pane, first get rid of the old one and clean up the area using an abrasive and a pull-type paint scraper or a wood chisel.

After the sash has been installed, you can apply a silicone caulk over the glass. This will ensure that it won't be leaking or fade over time.

Take the glazing points out of the rabbets, the grooves in the sash, where the glass sits. If they're difficult to cut, place a hand tool such as a heating gun over them for a few minutes to soften them. If you're using a heating gun, be cautious not to scratch the railings of the sash or the sash itself by holding the tool too closely.

After 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.

After you have removed the old pane taken away, clean up the surrounding frame and wood. Scrape off any paint and sand down the rabbet grooves where the glazing points used to be.
