Once you've removed all the old putty, it is time to prepare the window frame to fit the new pane. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of the width and height. Take these measurements to an hardware store or home center, and get a piece of stock glass cut to size. You can also cut the glass by yourself if you have the appropriate tools.

After installing the glass Apply caulking around the edge. This will make the glass weatherproof. Install a glazier's pointing on both sides of the frame. This will help secure the pane. The points should not be too tight that they create friction between the frame and sash however they should not be loose.

Before applying the putty on the surface, gently knead it until it is smooth and free of lumps. Make it into pencil-sized strips. Apply the first strip in the corner of the frame, working from one corner to the other so that it is even and smooth.

Glazier's Points

The glazier's points are tiny triangular pieces of metal which help to secure the glass to the frame without causing any damage to the fragile surface. Understanding how to use these little helpers is easy and could save you money on a professional installation or the cost of buying new glass.

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 that the pane fits comfortably and allows for expansion and contraction.

Place the new pane into the frame and push it in with your hands. Then, you can use the point of your chisel or the back of the putty knife to make a tap on the glazier's facets, as shown in Figure 11. After you're done, the points should be in line with the top edge of the pane, and the shoulders of the points should be just below the lip of the rabbet groove.

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

Install the new window sash after the glazing compound has dried. First, saturate the wood with a heavy coat of Linseed oil. This will prevent the new putty from drying out or cracking when it absorbs moisture. Apply the coating using a brush this coat, or the point of the putty blade.

Once the sash is installed and sanded, apply a fresh silicone caulk to the glass to ensure that it will not leak or change color over time.

Take out the glazing points in the rabbets. These are the grooves on the sash, which is where the glass is located. If they're hard to chisel, use a hand tool such as a heatgun over them to allow them to soften before. When using a heated tool, be careful to not scratch the sash or its railings.

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