It is best to work using a sturdy ladder instead of the ground and have someone stand below the sash to help hold it steady.

Make sure the window frame is ready to accept the new pane after you have removed the old putty. Find the width and the height of the sash opening, subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be sent to a hardware or home center store to have an item cut from stock glass to the right size. Alternately, you can cut the glass yourself if have the right tools.

After putting in the new glass, apply a small amount of caulking around the edge. This will make the glass weatherproof. Then, you can install a glazier's pointing on each side of the frame to secure the pane into the right place. The points shouldn't 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, you must knead it thoroughly until it becomes soft and free from lumps. Then you can roll it into pencil-sized strips. Apply the first strip to the corner of the frame, working from one corner to another to ensure it is even and smooth.

Note down the exact dimensions of the frame. Bring these measurements to a hardware store or home center, and have the new pane cut slightly smaller than the frame's opening. This will ensure a tight fit and will allow room for expansion and contraction.

Place the new pane into the frame and push firmly using your hands. Then use the point of your chisel or the back of the putty knife to pierce the glazier's points as illustrated in Figure 11. When you're done, they should be in line with the top edge of the pane. the shoulders of the points should be below the rabbet's lip. groove.

Apply a thin bead of glazing compound on 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 completely.

Install the new window sash when the glazing compound has dried. First, you need to coat the wood with an even layer of linseed. This will stop the new putty from drying out and cracking as it absorbs moisture. Apply this coat with a brush or the edge of your putty knife, then use the chisel, or the back end from the putty knife to gently hammer the new sash and glazier's point into the rabbet grooves. Repeat this process in intervals of 10 inches around the frame.

Putty

The glass is held in place with small clips made of metal called a glazier's point, and putty, often called glazing compound.

Remove the glazing points from the rabbets, the grooves in the sash, where the glass sits. If they're hard to chisel, use the hand tool, such as a heatgun over them to soften first. When using a heated tool, be sure to not scratch the sash's railings and sash.

Create a bed for your new pane by removing the old glaze points and putty. Roll a piece of glazing compound between your hands, and form it into a 1/2-inch thick.

If the new pane has damaged, you can use a silicone caulk or a glass glue that is based on solvents to fill in the crack before pressing it in the sash. Otherwise, you'll need to apply putty over the crack to form an impervious seal to keep water out.

The next step is to determine the width of the window's opening. You will need to take vertical and horizontal measurements of the entire opening as well as the thickness of the old pane.
