Make use of a wood chisel or putty knife to get rid of any remaining old putty around the frame and the window sash. Be careful and slow making sure not to break the existing window sash. It is a good idea to do this using a sturdy ladder instead of the ground and to have someone stand below the sash in order to help hold it steady.

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

After installing the new glass After installing the glass, apply some caulking on the edges. This will make the glass weatherproof. Install a glazier's point on both sides of the frame. This will ensure the pane. The points should not be so tight that they cause friction between the frame and the sash, but they should also not be loose.

Before applying the putty to the surface, gently knead it until it is soft and free from lumps. Cut it into pencil-sized pieces. The first strip should be glued to the corner of the frame. Work from corner to corner and ensure that it is even and smooth.

Glazier's Points

If you decide to sand wood, cover it with painter's tape to protect it from damage caused by accidental sanding.

Write down the dimensions of the frame. These measurements can be taken to a home center or hardware store, and the new pane will be cut to a smaller size. This will ensure a secure fit and leave room for expansion and contraction.

Place the new pane in the frame and push it in using your hands. Then use the point of your chisel or back end of the putty knife to tap in the glazier's points, as shown in Figure 11. After you're done, the points should be level with the top edge of the pane and the shoulders that are raised of the points should be below the lip of the rabbet groove.

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.

Install the new window sash once the glazing compound has dried. The first step is to coat the wood with a thick layer of linseed. This will prevent the newly-created putty from drying out or cracking when it absorbs moisture. Use a brush to apply this coat, or the tip of the putty blade. Then, use the chisel that is on the back of the tool or the back of the putty handle to gently smash the new sash or glazier's point into the rabbet grooves.

Putty

After the sash has been reinstalled it is possible to apply a silicone caulk over the glass. This will ensure that it doesn't leak over time or discolor.

Take the glazing points out of the rabbets and the grooves in the sash where the glass sits. If they're difficult to work out, try placing a hand tool like a heat gun over them to soften them before you do. If you're using a heated gun, make sure not to cause damage to the railings or sash by holding the tool too tightly.

Make the bed for your new pane after you have removed the old glaze points and putty. Roll a piece of glazing compound between your hands, shaping it to be around 1/2-inch thick. Then, you can press it into the rabbets, where the glass will be. It is essential that the glass rests against the putty in all places on each side If you have to, lightly tap the glass into the rabbet using your thumb.

If the new pane is cracked, you can use a silicone caulk or a glass glue made from solvents to fill in the crack before pressing it into the sash.

These should be sanded down to bare wood, so that you can paint them the same color as the rest of the frame. After sanding the wood, apply a layer of flax oil. This will help extend its life.

Next, measure the dimensions of the window opening. It is necessary to measure the vertical and horizontal dimensions of the entire opening as well as the thickness. Subtract 1/8 inch from each measurement to ensure you get the exact measurement for the new pane. This will also allow for expansion and contraction of the glass in times of seasonal changes.
