Then, use a wooden chisel, or putty knife, to remove the rest of the old putty from around the frame and the sash. Work slowly and carefully making sure not to damage the old window sash. It is recommended to work on a stable ladder instead of the ground, and to have someone stand below the sash in order to help hold it in place.

After you have removed all the old putty, you can prepare the window frame for the new pane. To allow for seasonal expansion or contraction by subtracting 1/8 inch from the measurements of the width and height. Bring these measurements to a hardware store or home center and find a piece glass cut to size. You can also cut the glass yourself if have the tools you need.

After installing the new glass, apply some caulking to the edge. This will make the glass weatherproof. Then install a glazier's point on each side of the frame to secure the pane into its place. The points should not be so tight as to cause friction between the sash and the frame, but they also should not be too loose.

Before applying the putty on the surface, knead thoroughly until it is soft and free from lumps. Cut it into pencil-sized pieces. Apply the first strip to the corner of the frame. Work from one corner to another to ensure it's even and smooth.

Glazier's Points

Install the new window sash once the glazing compound has dried. First, coat the wood with an even layer of linseed. This will prevent the newly-created putty drying out or cracking as it absorbs moisture. Apply the coating using a brush this coat, or even the tip of the putty blade.

Putty

A baseball that is thrown or a rock that is errant or falling branch could cause a window pane to break or crack. Fortunately, the majority of windows can be easily replaced by simply placing a new piece of glass in its the proper place. The glass is held in place using tiny metal clips known as a glazier's point, and putty, also called glazing compound.

If you're using a heating gun, be cautious not to cause damage to the railings or sash by using the tool too close.

Once the old glaze points and putty have been removed, prepare a bed for the new pane. Roll a piece of glazing compound between your hands, forming it to be around 1/2-inch thick. Press it into the rabbets, where the glass will be put. The glass should rest against the putty on both sides. If needed gently tap your glass into the rabbet with your thumb.

If the new pane has cracked, you can apply a silicone caulk or glass glue made from solvents to fill in the crack prior to pressing it into the sash. If not, you'll have to apply putty on the crack to form an airtight seal and keep water out. After the putty has dried and the film is oily, Replace window Pane wipe it off the glass with an abrasive and allow it to dry completely before painting. Paint before the putty is completely dry.

After you have removed the old pane removed clean the surrounding frame and wood. Scrape off any paint that has been used, and sand the rabbet grooves that the glazing points were placed. Sand them down to bare wood surfaces, so that you can paint the frames with the same shade. After sanding, apply a coat of flax oil on the wood that is not sanded down to help extend its lifespan.

Then, take measurements of the dimensions of the window's opening. You will need to measure the vertical and horizontal dimensions of the entire opening as well as the thickness.
