Then, use a wooden chisel or putty knife to remove the remaining old putty around the frame and the sash. Be careful to not break the window sash. Take your time and work slowly. It is recommended to work using a sturdy ladder instead of the ground and to place someone on the sash to help keep it in place.
Make sure that the window frame is ready to accommodate the new pane after you have removed the old glue. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of 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 by yourself if you possess the appropriate tools.
After installing the glass, apply a small amount of caulking to the edge. This will make the glass weatherproof. Then install a glazier’s point on the frame’s opposite side to secure the pane into its place. The points should not be so tight that they create friction between the frame and the sash however they should not be loose.
Before applying the putty on the surface, you must knead it thoroughly until it is soft and free from lumps. Then, roll it into pencil-size strips. The first strip should be glued to the frame’s corner. Work from one corner to another and ensure that it is even and smooth.
Glazier’s Points
The glazier’s points are tiny triangular metal pieces that help secure the glass to the frame without causing damage to the delicate surface. It’s simple to learn how to use this hidden tool, and you’ll save money on the cost of a professional installation.
After 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.

Note down the exact dimensions of the frame. Take these measurements to a hardware store or home center and request that the new pane made slightly smaller than the frame’s opening. This will ensure a secure fit and leave room for expansion and contraction.
Place the new window in the frame and press it in place by using your hands. Make use of the chisel’s point, or the edge of the putty blade to smudge the glazier’s points, as shown in Figure 11. After you’re done, the points should be level with the top edge of the pane and the shoulders of the points should be just below the rabbet’s lip. groove.
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 this to dry and cure fully.
Once the glazing compound has dried, you’re ready to install the new window sash. First, you need to coat the wood with an even layer of linseed. This will keep the new putty from soaking up moisture and drying out and cracking over time. Apply this coat using a brush or the tip of your knife, then employ the chisel or back end from the putty knife to gently hammer in the new sash and glazier’s tips into the grooves of the rabbet. Repeat this process in intervals of 10 inches all around the frame.
Putty
A baseball that is thrown, an errant rock or a falling branch can cause a window to crack or break. Luckily, most windows can be easily replaced by simply putting a new piece of glass in its the right place. The glass is held in place by a small metal clip called a glazier’s point, and putty, which is often called glazing compound. Before installing a new pane, first take out the old one and clean up the area with an abrasive and an abrasive scraper that is a pull type or an abrasive wood chisel. Wear safety glasses and gloves while you do this work. You’ll need a heat gun if the window is glued to the frame.
If you are planning to replace the original sash, take off the molding that supports the old pane. Sand the sash until it’s flat and ready for new caulk. Once the sash is reinstalled, you can apply a silicone caulk on the glass. This will ensure that it doesn’t be leaking or fade over time.
Take the glazing points out of the rabbets, the grooves in the sash that the glass is. If they’re difficult to chisel, hold the hand tool, such as a heating gun over them to allow them to soften before. If you’re using a heating gun, make sure not to scratch the sash or its railings by holding the tool too close.
After the old glazing points and putty have been removed, make a bed for the new pane. Roll a rope of glazing compound between your hands, and form it to be around 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, so if you need to tap it, gently press the glass into the rabbet with your thumb.
If the new pane is cracked then you can seal it with a solvent-based glass glue or silicone caulk prior to pressing it into the sash. If the crack isn’t sealed, you’ll need to use putty to keep the water out. Once the putty is dry clean the oily film from the glass and let it dry completely before you paint. Paint after the putty is completely dry. It will not make a strong seal and could be leaking or discoloring over time.

When you are ready to begin with the removal of the window pane. Remove the glazing points made of metal that are attached to it. These are tiny triangles of metal which act as “nails”, holding the window in place. They are submerged beneath a layer of glazing putty that is then cured to form a solid, molded wedge that secures the window in place and conceals the points.
After taking off the old pane clean the frame and the wood. Scrape away any paint and sand down the rabbet grooves where the glazing points were. These should be sanded down to the point of being bare, so that you can paint them the same color as the rest of the frame. After the sanding process, apply a coat of flax oil to the wood’s surface to help extend its lifespan.
The next step is to measure the dimensions of the window’s opening. You’ll need to determine the horizontal and vertical 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 also allow for expansion and contraction of the glass during seasons of change. You can take these measurements to a hardware store or replace window pane home improvement shop and get 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.
