Once the old glass is removed, clean the inside of the window sash using a damp cloth to clean off any dirt or dust. Now you can install a new glass pane.

Many hardware stores will cut a piece of glass for you if they have the measurements. Warm up a few tablespoons of putty, then roll it into a 3/4-inch rope. Place the putty along the edge of the rabbet and rest the blade of your putty knife at a 45-degree angle against the frame rabbet. To cut a section from the pane, move the knife in a straight and straight line along the edge of glass. Repeat the process with the remaining edges of the glass, and then scrape off the excess putty. Take the broken Pane A damaged pane of glass in a French-style door is not just an eye-sore, but it can also be a safety risk.

If the original nails didn't penetrate the molding, you can put new wire nails into the holes left by the old nails. By drilling the holes prior to drilling, you can prevent the nails from splitting through the molding. You can drill the holes with very thin bits from a hardware store that is well stocked. Cut a New Pane of Glass Double-check the spacing around the frame of the window as well as the edges before ordering a replacement pane. You may need to adjust spring clips or the metal triangulars to hold it in place if you find gaps. You should also make sure that the new pane you purchase is the right size for the opening. If it's too large it could cause leaks or other issues. The first step is to prepare the work surface. Using a putty knife, scrape away the old compound on both sides of the frame to expose the wood. If the rabbets are too rough to smooth with a putty knife gently sand them and brush on an exterior primer. This will stop the new glazing from absorbing moisture from the wood and reduce its life. After the frame is clean and prepped, warm a handful of putty by kneading it until it's soft and malleable. Use the putty knife apply a thin layer to the inside corners of the rabbets. This creates a narrow bed for the glass to rest upon. Repeat the process for the remaining exposed edges. Remove any remaining metal points from the grooves of the sash after the putty has dried. Before attempting to remove them, wear goggles that are safe to shield yourself from glass shards. The low setting of heat guns can be used to gently heat the metal and loosen it so you can take it off using pliers. Place the glass on the table to test fit. Adjust the glass as needed before securing it with spring clips or triangulars made of metal. Ensure that the gap between the frame and the glass is even and uniform across all sides. You can also test the sash's movement to make sure that the new pane won't interfere with closing or opening the window. If you encounter any issues with the installation, consult an expert who specializes in restoration to help you repair and preserve your historic home. Install the Pane of Glass Before you install the new glass pane, you should test-fit it to make sure it is snugly fitted. Take measurements of the width and height of the window opening by measuring to the outside edge of the L channels. Subtract 1/8 of an inch from each measurement to determine the size of glass you require. Slightly undersizing the pane will make it easier to install and will allow for seasonal expansion and contraction of the wood frame. Take your measurements to an hardware store or home center, and let them cut a piece of glass for you. You can cut the glass yourself, if you have a large piece available. After removing the old glass pane, clean the window sash grooves. Remove any glazing points that were used to support the previous pane. This can be done using a scraper that is a type of pull, or a chipper. If the grooves have lots of putty that is hardened you can soften it using a heat gun. Cover the windows and moldings around them with aluminum foil in order to shield them from heat. Scrape and sand the rabbets on which the glass is placed, then brush an exterior primer over them to help prevent the putty from drawing out its natural oils and reducing its lifespan. It is also recommended to clean the sash to get rid of dust and dirt from the grooves. Knead a small amount of putty until it is warm and flexible Then press it into the rabbets where the glass will go. Neatness isn't important at this point. Place the new pane in the rabbets. Then, move it around and apply even pressure using your fingers to ensure that it's placed in the right place. Fill any holes in the frame with silicone caulk. Then install the new glass. If the frame has other fastening mechanisms, like L-channels for example, employ a hammer for prying them out from the sash grooves. Get rid of any shards that might have become loose during the removal of the frame. To keep pests and water from entering the house, apply a clear silicone caulk on the bottom edge of frame where it meets floor.
