Glass
If your single-pane windows are outdated broken, deteriorating or damaged replacing them with more modern glass that is tempered or insulated will increase energy efficiency and decrease noise while also preserving the historic integrity of older homes. The process of replacing the window pane is easy and can be completed by homeowners with basic hand tools. In addition to a replacement pane, the following components are needed for the replacement process: latex glazing putty pliers, glazier's points and an electric heater to warm the old putty, if needed. Wear safety goggles and gloves prior to beginning. Working with broken glass could result in serious injuries.
Begin by removing any remaining broken pieces of glass. This is best accomplished with pliers, however, a flathead screwdriver can also be effective in the pinch. Make use of a wood chisel or putty knives, to take away any old putty that remains around the frame and window sash. Be careful not to break the window sash. Work slowly and carefully. This should be done on an elevated ladder, not on the ground. Also, ensure that someone on the ground to hold it steady.
Prepare the window frame to receive the new pane once you have removed the old putty. Take measurements of the width and height of the opening in the sash and subtract 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be sent to a home center or hardware store to have cut a piece of stock glass to the right size. Alternately, you can cut the glass yourself, if you have the tools you need.
After putting in the new pane, run a small bead of caulking along the edge to ensure it is weatherproof. Then, you can install a glazier's pointing on each side of the frame to secure the pane in the right place. The points shouldn't be so tight that they cause friction between the frame and sash However, they should not be loose.
Before applying the putty make sure to knead it until it is soft and free of lumps. Then you can roll it into pencil-sized strips. Apply the first strip to the frame's corner. Work from corner to corner and ensure that it is even and smooth.
Glazier's Points
The glazier's points are small triangular metal pieces that allow glass to be secured to the frame without causing damage to the delicate surface. It's easy to understand how to use this hidden tool, and you'll save money on the cost of an installation by a professional.
After taking off the old putty, glazier points, and any other residue, clean the frame thoroughly using a utility knife. If needed it is necessary to lightly sand the wood in the grooves of the rabbet to smooth rough spots. If you decide to sand wood, protect it with painter's tape to avoid accidental damage.
Note down the dimensions of the frame. Take these dimensions to a hardware store or home center, and have the new pane made slightly smaller than the frame's opening. This will ensure that the pane fits snugly and allows for expansion and contraction.
Place the new pane in the frame and push it in with your hands. Make use of the point of the chisel or the back of the putty knife to tap in the glazier's points, as illustrated in Figure 11. When you're done taping, they should be in line with the top edge of the pane and the shoulders of the points should be below the lip of the rabbet groove.
Apply a thin layer of glazing compound over the edges of the glass that has been made and into the rabbet grooves, to seal and

After the glazing compound dries, you're ready to install the new window sash. First, you need to coat the wood with an even layer of linseed. This will stop the new putty from soaking up the moisture and deteriorating and cracking with time. Apply this coat with a brush or the edge of your putty knife, then use the chisel, or the back end of the knife to gently press the new sash and glazier's point into the grooves of the rabbet. Repeat this process at intervals of 10 inches around the frame.
Putty
A baseball thrown at you, an errant rock or falling branch could cause a window pane to break or crack. Luckily, most windows can be replaced by simply putting a brand new piece in place. The glass is held in place using tiny metal clips known as a glazier's point and putty, which is often called glazing compound. Remove the old pane and clean the area using an abrasive, pull-type scraper or wood chisel. Wear gloves and safety glasses when you work. You'll need a heating gun if the window is glued into the frame.
If you are planning to
replace window Pane your original sash, you must remove the mold that holds the old pane. Sand the sash until it's flat and ready to receive new caulk. After the sash has been re-installed, apply a new silicone caulk to the glass to ensure it doesn't swell or fade as time passes.
Remove the glazing points from the rabbets, or the grooves in the sash, where the glass is. If they are hard to chisel, use an instrument like a heat gun over them to allow them to soften before. When using a heating tool, be careful to avoid damaging the sash's railings and sash.
Create a bed for your new pane after removing the old glaze and putty. Roll a piece of glazing compound between your hands, shaping it into a 1/2-inch thick. Place it into the rabbets, where the glass will be placed. It is essential that the glass rests against the putty on each side If you have to tap it, gently press the glass into the rabbet using your thumb.
If the new pane is cracked, you can cover it with a solvent-based glue or silicone caulk prior to pressing it into the sash. If the crack isn't sealed, you will need to use putty to keep the water out. When the putty dries then clean the oily film off the glass using the help of a rag. Allow it to completely dry before painting. If you paint before the putty is fully dry, it won't create a solid seal and could be leaking or discoloring in time.
Paint
You might be worried about replacing a damaged piece of glass. It's true that replacing a single pane of glass doesn't have to be costly if you do it on your own. In fact even windows with double panes can be replaced for a fraction of the cost of an expert.
First, if you're working on a large window, ensure that it is securely fastened to the frame. Using the proper tools and techniques to accomplish this task fairly easily and fast.
Once you're ready to begin with the removal of the old window by removing the metal glazing points that are attached to it. These are essentially small metal triangles that function as "nails" that keep the window in place within the frame of wood. They are placed under a bead or glazing glue which hardens into solid wedge that holds the wood frame firmly in position and hides the sharp edges.
After you have the old pane taken away Clean up the frame and wood. Scrape off any paint and sand down the rabbet grooves where the glazing points were. Sand them down to clean wooden surfaces, allowing you to paint the frames with the same shade. After sanding, apply a coat of flax oil on the wood that is not sanded down to prolong its life.
Next, measure the size of the window opening. You will need to measure the vertical and horizontal dimensions of the entire opening as well as the thickness. Subtract 1/8 inch from each measurement to ensure you have the exact size for the new pane.
