It is a good idea to do this using a sturdy ladder rather than the ground, and to have someone standing below the sash in order to help hold it steady.

Make sure the window frame is ready to accept the new pane after you have removed the old putty. Measure the width and 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 cut the glass 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 edges to ensure it is weatherproof. Install a glazier’s pointing on both sides of the frame. This will ensure the pane. The points should not be too tight that they cause friction between the frame and the sash however they should not be loose.

Before applying the putty on the surface, gently knead it until it becomes soft and free from lumps. Make it into pencil-sized strips. The first strip should be glued to the corner of the frame. Work from one corner to the next, making sure it is even and smooth.

Glazier’s Points

Take the dimensions of the frame and note down precise measurements. These measurements can be brought to an hardware or home centers 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.

Insert the new pane into the frame and push it in using your hands. Utilize the chisel’s point or the edge of the putty blade to tap in the glazier’s points, as illustrated in Figure 11. The glazier’s points should sit aligned with the top edge of your pane, and the shoulders should be just below the lip.

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

After the glazing compound dries and the glazing compound is dry, you can install the new window sash. The first step is to coat the wood with a thick coat of Linseed oil. This will stop the new putty from sucking up moisture and deteriorating and cracking with time. Apply this coat using a brush or the edge of your putty knife, and then use the chisel or the back end of the putty knife to gently press the new sash and glazier’s tips into the grooves of the rabbet.

Putty

A baseball hit, a rock thrown in error, or a tree falling can result in a cracked or cracked window. Luckily, most windows can be repaired by simply putting a brand new piece in the right place. The glass is held in place with small clips made of metal called a glazier’s point, and putty, also called glazing compound. Remove the old pane and clean the area with a rag, a pull-type scraper or wood chisel. Wear protective glasses and gloves while you do this work.

If they’re difficult to chisel, use an instrument such as a heating gun over them for a few minutes to soften them. If you’re using a heat gun, be cautious not to damage the sash or its railings by holding the tool too closely.

After the old glaze points and putty have been removed make a bed for the new pane. Roll a rope made of glazing compound between your fingers, and make it about 1/2 inch thick. Then, press it into the rabbets in which the glass will be. The glass must be positioned against the putty on both sides. If you need to, lightly tap your glass into the rabbet using your thumb.

If the new pane has cracked, you can use a silicone caulk or glass glue that is based on solvents to fill in the crack prior to pressing it into the sash. If the crack isn’t sealed, you’ll need to apply putty to keep water from getting in. When the putty dries then clean the oily film off the glass with the help of a rag.
