Wear safety goggles and gloves before you begin. Working with broken glass could result in serious injuries.
Begin by removing any remaining broken pieces of glass. This is best accomplished with a pair of pliers, though using flathead screwdrivers can be effective in a pinch. Then, use a wood chisel or putty knife remove the remaining old putty from around the frame and the sash. Be careful to not scratch the window replacement companies — go here, sash. Take your time and work slowly. It is a good idea to do this on a sturdy ladder rather than on the ground and place someone on the sash in order to help hold it in place.
Make sure that the window frame is ready to accommodate the new pane after you have removed the old putty. To allow for seasonal expansion or contraction and window replacement companies contraction, subtract 1/8 inch from the measurements of the width and height. Take these measurements to a hardware store or home center and get a piece of stock glass cut to size. You can also cut the glass yourself if you have the right tools.
After installing the new glass, apply a small amount of caulking on the edges. This will make the glass weatherproof. Then, you can install a glazier’s pointing on each side of the frame to hold the pane in place. The points shouldn’t be so tight that they create friction between the sash and the frame but they should not be too loose.
Before applying the putty to the surface, you must knead it thoroughly until it becomes soft and free from lumps. Cut it into pencil-sized pieces. The first strip should be placed in the corner of the frame, moving from one corner to another so that it is smooth and even.
Glazier’s Points
The glazier’s facets are small triangular pieces that allow glass to be secured into a window frame without damaging or scratching the delicate surface. It’s simple to learn how to use this nefarious tool, and you’ll save money on the expense of a professional installation.
Once the old putty and the glazier’s points have been removed Clean the frame thoroughly using a utility knife to get rid of any remaining residue. If necessary you can lightly sand the wood along rabbet grooves to smooth out rough areas. If you sand wood protect it with painter’s tape to protect it from damage caused by accidental sanding.
Measure the empty frame’s dimensions and write down accurate measurements. Take these dimensions to an hardware store or home center and have the new pane cut slightly smaller than the frame’s opening. This will ensure that the pane fits perfectly and allows for expansion and contraction.
Place the new pane into the frame and push it in with your hands. Make use of the point of the chisel or the back of the putty blade to tap in the glaziers’ points as illustrated in Figure 11. The glazier’s points should sit flush against the top edge of your pane and the shoulders should be just beneath that lip.
Apply a thin layer of glazing compound on the edges of the new glass and into the rabbet grooves, to seal and protect them. Allow it to dry and cure completely.
Install the new window sash after the glazing compound has dried. The first step is to coat the wood with an even layer of linseed. This will prevent the new putty from taking up moisture and drying out and cracking with time. Apply this coat using a brush or the tip of your putty knife, and then use the chisel or the back end from the putty knife to gently hammer in the new sash and glazier’s point into the grooves of the rabbet. Repeat this procedure every 10 inches around the frame’s perimeter.
Putty
A baseball thrown or a rock thrown in error or a branch falling can cause a broken or cracked window pane. Most windows can be replaced easily by putting in a new piece. The glass is held in place by a small metal clip, referred to as a glazier’s point and putty. This compound is also called glazing compound. Before installing a new pane, first get rid of the old one and clean up the area with the help of a rag, the pull-type paint scraper or the wood chisel. Wear gloves and safety glasses when you work. You’ll need a heat gun when the window is fixed to the frame.
If you’re planning to install the original sash, gently remove any molding pieces that are used to secure the old pane. Sand the sash until it is flat and ready for new caulk. Once the sash is reinstalled then, you can apply a silicone caulk on the glass. This will ensure that it doesn’t get soiled or discolor over time.
Remove the glazing points from the rabbets. These are the grooves in the sash, where the glass is. If they are hard to chisel, use an instrument such as a heatgun over them to allow them to soften before. If you’re using a heated gun, be careful not to cause damage to the railings of the sash or the sash itself by placing the tool too close.
After the old points of glazing and putty are removed, prepare a bed for the new pane. Roll a rope of glazing compound between your hands, forming it to be around 1/2-inch thick. Press it into the rabbets, where the glass will be put. The glass must be positioned against the putty on both sides. If necessary gently tap your glass into the rabbet with your thumb.
If the new pane is damaged, you can use a silicone caulk or a glass glue made from solvents to cover the crack before pressing it in the sash. In other cases, window replacement companies you’ll need to putty over the crack to form an impervious seal to keep water out. Once the putty is dry, wipe the oily film from the glass and let it dry completely before you paint. Paint before the putty has dried completely.

Paint
If you’ve suffered a break in a window pane, then you may be worried about the cost of replacing it. The truth is, replacing a single piece of glass doesn’t need to be costly even if you do it your own. In fact windows with double panes can be replaced at a fraction of the cost of an expert.
If you’re working with large glass windows first, ensure that it is securely fixed to the frame. By using the correct tools and techniques, you can accomplish this task fairly easily and fast.
When you are ready to begin with the removal of the window pane. Take out the metal glazing points attached to it. These are essentially small metal triangles which function as «nails» which hold the window in place within the frame of wood. They are buried beneath a glaze putty or bead that sets to form a solid wedge that holds the frame in place and hides the sharp edges.
After you have removed the old pane removed Clean up the frame and wood. Scrape off any paint that has been used and sand the rabbet grooves that the glazing points were placed. Sand them to bare wood surfaces, so that you can paint the frames the same color. After sanding, apply a layer of flax oil to the wood that is not sanded down to prolong its life.
The next step is to determine the width of the window’s opening. You will need to measure the vertical and horizontal dimensions of the entire opening, as well as the thickness. To get the exact size of the new pane, subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass. Take these dimensions to a hardware or home improvement store and have the glass cut for you.
Now, it’s time to bed the new window pane. To do this, place the pane inside the frame and move it around until a 1/16 inch of putty remains between the edge of the glass and the sash on all four sides. Use a putty knife to smear the putty evenly, making sure that there isn’t an excessive amount of excess putty in the corners and along the edges. When the putty dries, it can be painted with the same color as the frame to prevent water and air from leaking into the frame and causing fogging.
