This can be done best on an elevated ladder, not on the ground. Also, have someone on the ground to ensure it is held steady.

Once you have removed all the old putty, it is time to prepare the window frame to fit the new pane. 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 hardware or home center store to have cut a piece of glass that is in stock to the correct size. You can also cut the glass yourself if have the appropriate tools.

After installing the new pane After installing the new pane, apply a small amount of caulking around the edge to ensure it is weatherproof. Install a glazier's pointing on both sides of the frame. This will ensure the pane. The points shouldn't be tight enough to create 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 make it into pencil-sized strips. Place the first strip to the corner of the frame, working from one corner to the other to ensure it is even and smooth.

Glazier's Points

The glazier's points are the tiny triangular pieces of steel which help to secure glass into frames for windows without scratching or damaging the fragile surface.

Lightly sand the wood in the rabbet grooves, if necessary, to smooth out rough areas. If you do sand your wood, Replace Window Pane make sure to protect it with painter's tack to avoid accidental damage.

Take the dimensions of the frame and note down precise measurements. Take these measurements to a hardware store or home center and request that the new pane cut 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 place using your hand. Then use the point of your chisel or back end of the putty knife to make a tap on the glazier's facets, as illustrated in Figure 11. The glazier's point should be in line with the top edge of the pane and the raised shoulders should be just below the lip.

Apply a thin layer of glazing compound on the edges of the new glass and in the rabbet grooves to seal and protect them. Allow it to dry completely and cure.

After the glazing compound dries it's time to put in the new window sash. The first step is to coat the wood with a heavy coat of Linseed oil. This will prevent the new putty from sucking in the moisture and drying out and cracking with time. Apply the coat using a brush or the edge of your putty knife, and then employ the chisel or back end of the putty knife to gently press the new sash and glazier's point into the rabbet grooves.

Putty

After the sash has been installed it is possible to apply a silicone caulk over the glass. This will ensure that it won't get soiled or discolor over time.

Remove the glazing points from the rabbets and the grooves in the sash that the glass is. If they're difficult to cut out, you can try holding the hand tool, such as a heat gun over them to soften them before you do. When using a heat tool, be careful to avoid damaging the sash's railings and sash.

Once 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, shaping it into a 1/2-inch thick. Place it into the rabbets, where the glass will be placed.

They are placed under a bead of glazing putty, which is then cured to form a solid, formed wedge that holds the window firmly in place and hides the window's points.

Once you have the old pane removed clean the surrounding frame and wood. Scrape away any paint and sand down the rabbet grooves where the glazing points used to be. They should be sanded to the point of being bare, to allow you to paint them the same color as the rest of the frame. After sanding the wood, apply a layer of flax oil. This will help to extend its life.

Then, take measurements of the dimensions of the window's opening. It is necessary to take vertical and horizontal measurements of the entire opening, and also the thickness of the old pane. To determine the exact dimensions of the new pane, subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass. Bring these measurements to your local hardware or home improvement store and ask them to cut you a piece cut for you.

Now, it's time to bed the new window pane.

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.
