If the putty is hard to get rid of, you can use a heat gun to soften it. Hold the heat gun an inch away from the glass, and move it forwards and backwards to spread the warmth. Put doubled sheets of aluminum foil on the adjacent panes to prevent them from cracking due to the heat.

If the nails that were used originally did not penetrate the molding, you can put in new wire nails to fill in the holes left by the previous ones. By drilling the holes prior to drilling, you can stop the nails from splitting through the molding. You can make holes using tiny bits from the hardware store that is well stocked. How to cut a new Pane Of Glass Before purchasing a new piece of glass, ensure that the spacing around the frame and the edges of the window are equal.

This will stop the new glazing from drawing moisture from the wood, shortening its lifespan. After the frame has been cleaned and prepared, rub the putty until it is soft and malleable. Use the putty knife to apply a thin layer to the inside corner of the rabbets. This creates a narrow bed for the glass to rest on. Repeat the process for the remaining exposed edges. Remove any remaining metal pieces from the grooves of the sash after the putty has dried. Before attempting to remove them, wear goggles with safety features to shield yourself from glass shattering. A heat gun on an low setting can help you gently warm up and loosen the metal, so you can bend it out of the frame using pliers. Once the glass and frame are ready, test-fit it by sliding it into its place. Adjust the glass as necessary before you secure it with spring clips or metal triangulars. Make sure the gap between the frame and the glass is uniform on all sides. Test the movement of the window sash and make sure the new pane does not hinder the closing or opening.

This will also allow for seasonal expansion and contracting of the wood frame. Bring your measurements to a hardware store or home center, and let them cut a piece glass for you. Alternately, you can cut the glass yourself if you happen to have a huge sheet of stock glass handy. After removing the glass pane, clean the window sash grooves. Remove any glazing points that were used to support the previous pane. A pull-type paint scraper or a chisel will work to accomplish this job. If the grooves have an abundance of putty that has been hardened, you can gradually soften it with a heat gun. Cover the windows and moldings around them with aluminum foil in order to protect them from heat. Scrape and sand the rabbets in which the glass is placed, then brush an exterior primer over them to help prevent the putty from drawing out its natural oils and shortening its life. You should also clean the sash to remove any dirt and dust from the grooves. Place a small amount of it into the rabbets where the glass will be placed. At this stage, cleanliness is not a factor. Make sure to press the new pane into the rabbets, and then move it using your fingers. If there are any holes in the frame of wood around the glass, fill them with silicone caulk before installing the new glass. If the frame is equipped with other mechanisms for fastening, like L-channels, you can use a hammer to pry them out from the sash grooves. Remove any shards that may have become loose during the removal of the frame. To prevent pests and water from entering your home Apply a clear silicone caulk on the frame's bottom edge where it meets floor.
