Broken Glass
Broken glass isn't just unattractive, it can also let valuable heat and sunlight escape from your home. Fortunately, it's often possible to repair a broken window pane without the need for a complete replacement.
Start by putting on protective gloves and safety glasses. You can also apply duct tape or painter's tape to make an "X" on the glass you plan to remove. This will prevent any shattered glass from falling onto you while you work.
If you have a small crack in the glass of your window you can cover it with tape to keep out rain, wind and insects. If the crack is superficial, a single strip of tape is enough. However, if the weather is likely to get worse before you can replace the window, you might want to use a heavy-duty plastic cover like the trash bag or tarp.
For cracks that aren't as shallow try using a tough adhesive designed specifically for windows, like Loctite Super Glue Glass. This high-tech glue is made to bond to glass and dries clear to give a perfect finish. Apply it to the crack and let it dry completely before applying a new layer.
Glass windows can also develop stress cracks. They're typically caused by dramatic temperature fluctuations, and can spread quickly across the entire glass window if they aren't fixed. To stop stress cracks from occurring make a small arc with glass cutters close to the crack. This prevents the crack from spreading and can slow it down by a day or so.
Measure the frame of the broken window to determine the size of the new pane. It should be slightly smaller than the opening to allow for expansion and contraction and to compensate for any imperfections in the frame or glass. After you've cut your glass to size apply glaziers' compounds around the edges of both the frame and the glass. After the compound has dried then paint it over it to match the rest of the window frame.

After the frame has been cleaned and the rabbet has been prepared It's now time to prepare the replacement pane. Order a piece of double strength glass that is one inch smaller in both directions. You'll also need to purchase glass points, which are steel triangles which help to hold the glass in place.
With the window sash removed and the pry-bar flat, use it to gently pry the sash off of the moulding of wood. You may need to scrape old glazing off using a utility blade or chisel. Then make use of the heat gun to warm up any putty that isn't able to come off. This will make it easier to remove.
Once the frame has been free of the molding then carefully press the new glass into its place. Fill in the gaps with either a glazier's tipped or a knife. After the putty dries paint it to match the frame. Paint it slightly over the edge of the compound and onto the glass to completely seal it.
