Then, use a wood chisel, or putty knife, to remove the remaining old putty from around the frame and the sash. Work slowly and carefully, taking care not to damage the old window sash. It is a good idea to work on a stable ladder instead of the ground and have someone stand below the sash in order to help hold it steady.

After you have removed all the old putty, it is time to prepare the window frame to fit the new pane. Find the width and the height of the opening for the sash, subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to an hardware store or home center and find a piece glass cut to size. Alternatively, you can cut the glass yourself, if you have the right tools.

After putting in 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 help secure the pane. The points should not be so tight that they create friction between the sash and frame however they shouldn't be too loose.

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

Glazier's Points

The glazier's points are tiny triangular pieces of metal that allow glass to be secured to the frame without damaging the delicate surface. It's simple to learn how to use this nefarious tool and you can save money on the expense of an installation by a professional.

Lightly sand the wood in the rabbet grooves if needed to smooth rough areas. If you decide to sand wood, protect it with painter's tape to protect it from damage caused by accidental sanding.

Take measurements of the empty frame and record precise measurements. Take these dimensions to an hardware store or home center and have the new pane cut smaller than the frame's opening. This will ensure that the pane fits snugly and allows for expansion and contraction.

Insert the new pane into the frame and press it down using your hands. Utilize the chisel's point, or the edge of the putty blade to smudge the glazier's points as illustrated in Figure 11. The glazier's points should sit aligned with the top edge of the pane and the raised shoulders should be just beneath that lip.

Apply a thin bead of glazing compound over the edges of the glass that has been made and into the rabbet grooves, to seal and protect them. Allow this to dry and cure fully.

After the glazing compound dries and the glazing compound is dry, you can install the new window sash. First, coat the wood with a heavy coat of Linseed oil. This will prevent the new putty from sucking in the moisture and drying out and cracking with time.

Remove the glazing points from the rabbets and the grooves in the sash where the glass is. If they're hard to chisel, hold the hand tool, such as a heatgun over them for a few minutes to soften them.

Create the bed for your new pane after removing the old putty and glazing points. Roll a rope of glazing compound between your hands, and form it into a 1/2-inch thick. Then, push it into the rabbets, where the glass will rest. It is crucial that the glass is positioned against the putty in all places on both sides If you have to, lightly tap the glass into the rabbet using your thumb.

If the new pane has cracked, you can use a silicone caulk or glass glue made from solvents to fill in the crack prior to pressing it into the sash. If the crack is not sealed, you will require putty to keep water from getting in. After the putty has dried then clean the oily film off the glass using the help of a rag.

After you have the old pane removed clean the surrounding frame and wood. Scrape away any paint and sand down the rabbet grooves, where the glazing points used to be. Sand them down to bare wooden surfaces so you can paint the frames with the same shade. After sanding the wood then apply a layer of flax oil. This will help prolong the life of the frame.
