Make use of a wood chisel or putty knives, to take away any old putty remaining around the frame and the window sash window replacement. Be careful not to scratch the window sash. Be careful and slow. It is recommended to do this on a stable ladder rather than on the ground, and to have someone standing below the sash to help keep it in place.

Once you have removed all the old putty, it is time to prepare the window frame for the new pane. To allow for seasonal expansion or contraction by subtracting 1/8 inch from the measurements of width and height. Take these measurements to an hardware store or home center and find a piece glass cut to size. You can cut the glass yourself if you possess the appropriate tools.

After installing the new pane, run a small bead of caulking around the edge to make it weatherproof. Then install a glazier's point on each side of the frame to secure the pane into the right place. The points shouldn't be too tight as to cause friction between the frame and sash but they shouldn't be too loose.

Before applying the putty, make sure to knead it until it's soft and free of lumps. Then, roll it into pencil-size strips. The first strip should be placed to the corner of the frame, moving from one corner to the other so that it is smooth and even.

Glazier's Points

The glazier’s points are small triangular pieces of metal that help secure the glass to the frame without causing damage to the delicate surface. Knowing how to use these hidden tiny pieces of help is simple and can save you money on a professional installation or the cost of buying new glass.

Note down the exact dimensions of the frame. These measurements can be taken to the hardware or home center store, and the new pane will be cut a bit smaller. This will ensure a secure fit and leave room for expansion and contraction.

Insert the new pane into the frame and push it in with your hands. Then, use the tip of your chisel, or the back of the putty knife to tap in the glazier's points, as shown 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 rabbet's lip. 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 protect them. Let it dry completely and cure.

Once the glazing compound has dried, you're ready to install the new window sash. The first step is to coat the wood with a heavy coat of linseed oil. This will stop the new putty from taking up the moisture and drying out and cracking with time. Apply the coat using a brush or the tip of your putty knife, and then employ the chisel or back end of the knife to gently press the new sash and glazier's point into the grooves of the rabbet. Repeat this procedure every 10 inches along the perimeter of the frame.

Putty

A baseball that is thrown, an errant rock or falling branch could cause a window pane to crack or break. Fortunately, windows can be easily replaced by simply putting a new piece in the proper place. The glass is held in place using small clips made of metal called a glazier's point and putty, which is often called glazing compound. Remove the old pane and clean the area using a rag, a pull-type scraper, or a wood chisel. Wear protective glasses and gloves while working. You'll require a heat gun when the window is fixed into the frame.

If you're planning to install 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. Once the sash is re-installed then, apply a new silicone caulk to the glass to ensure it won't leak or discolor in time.

Remove the glazing points in the rabbets. These are the grooves in the sash where the glass is located. If they're hard to chisel out, you can try holding the hand tool, such as a heat gun over them to soften them first. When using a heat tool, make sure to not damage the sash's railings and sash.

After the old points of glazing and putty have been removed prepare a bed for the new pane. Roll a rope made of glazing compound between your fingers, and make it about 1/2 inch thick. Place it into the rabbets, where the glass will be placed. It's important that the glass rests against the putty in all places on each side So if you have to tap it, gently press the glass into the rabbet with your thumb.

If the new pane is cracked, you can apply the silicone caulk or glass glue based on solvents to cover the crack before pressing it into the sash. In other cases, Replace Window Pane you'll need to putty over the crack to create a tight seal and keep water out. When the putty dries, clean the oily film off the glass with an abrasive and allow it to dry completely before painting.

When you are ready to start taking down the old window pane. Take out the glazing points made of metal that are attached to it. They are basically tiny 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 putty that sets to form solid wedge that holds the frame in place and hides the points.

After taking off the old pane clean the frame and Replace window pane the wood. Scrape off any old paint and sand the rabbet grooves in which the glazing points were placed. These should be sanded to bare wood to allow you to paint them the same color as the rest the frame. After the sanding process, apply a coat of flax oil to the wood that is not sanded down to help extend its lifespan.

Then, take measurements of the dimensions of the window's 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 that you have the exact size for the new pane. This will also allow for expansion and contraction of the glass in times of seasonal change. Bring these measurements to a hardware or home improvement store, and they will have cut the glass 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.

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.
