If the putty is hard to remove, you can employ a heat gun in order to soften it. Keep the heat gun about an inch from the glass and move it forwards and backwards to spread the warmth. Place two sheets of aluminum foil on the adjacent panes to keep them from cracking because of the heat. After removing the old glass, use a damp cloth and wipe the inside of the window sash to remove any dust or dirt. It is now time to install a new piece glass.

If the rabbets have become too rough to smooth with the putty knife then lightly sand them, and then apply an exterior primer. This will stop the new glazing from absorbing moisture from wood, shortening its lifespan. After the frame has been cleaned and prepared, rub a handfull of putty until it is soft and malleable. Apply a thin layer of it using the putty blade to the inside corners of the rabbets to create a bed on which the glass can rest. Repeat the process on the other edges of the rabbets. When the putty is dry and the putty is removed, you can remove any remaining glazing points from the grooves within the sash. Before you attempt to remove them, wear a pair of safety goggles to protect yourself from glass shards. Heat guns on low settings can be used to gently heat the metal, allowing it to loosen so that you can remove it using pliers. After the glass and frame are in place, test it by sliding it into its place. Adjust the glass as necessary before securing it using spring clips or metal triangulars.

Cover surrounding windows and moldings with aluminum foil in order to protect them from heat. You can also apply an exterior primer to keep the putty from absorbing its natural oils. Also, clean the grooves in the sash. Knead a small amount putty until it's warm and flexible, then press it into the rabbets where the glass will go. It's not important to be neat at this stage.
