Broken window panes are an issue that is serious, but they can usually be repaired. It is best to contact an expert if a single pane of glass has been broken into large shards, or if there is gaps between the panes. However, small cracks and missing pieces can be repaired by following these guidelines.
Wear heavy work gloves whenever you handle any type of glass. This is especially important when the glass is old. Before you attempt to remove the glass pane, apply newspaper to the frame's interior and place it behind the sash to catch any fragments that may fall. Additionally, you should cover the floor around the window with newspaper to prevent scratches. After you have secured the window with tape and taped it, take the sash off with a tool like long-nosed pliers. Then, move the glass shards out into a container (to later be disposed). Remove any nails or clips from the frame using pliers.
After the glass has been removed, you can start to repair the frame. Scrape off the old putty, paints, or varnish and the old glazier points. The use of heat guns to soften the putty, or the grooves that were glazier points. Once all the old putty is removed, re-smooth and sand the surface of the frame before applying the new glazing compound, ensuring it is snugly seated within the gap to prevent leaks.
The glass can be slid on and then firmly pressed in place. If the glass comes with gaskets, simply slide it on and press it in the frame. Paint the new compound to match the other windows in the room.
