It is recommended to work on a stable ladder rather than the ground and have someone stand below the sash in order to help hold it steady.

After you have removed all the old putty, you can prepare the window frame to fit the new pane. Measure the width and height of the sash opening, subtracting 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 a piece cut of glass that is in stock to the correct size. You can cut the glass yourself if you possess the appropriate tools.

After installing the new pane, run a small bead of caulking along the edge to seal it against weather. Install a glazier’s point on both sides of the frame. This will help secure the pane. The points should not be so tight that they cause friction between the frame and sash however they shouldn't be too loose.

Before applying the putty to the surface, knead thoroughly until it is soft and free of lumps. Cut it into pencil-sized pieces. Apply the first strip to the frame's corner. Work from one corner to the next and ensure that it is even and smooth.

Glazier's Points

Write down the dimensions of the frame. Take these dimensions to a hardware store or home center and have the new pane cut smaller than the frame's opening. This will ensure a tight fit and leave room for expansion and contraction.

Place the new pane in the frame and press it into the frame by using your hands. Utilize the point of the chisel, or the back of the putty blade to tap the glazier's points as illustrated in Figure 11. When you're done taping, they should be flush with the top edge of the pane, and the shoulders that are raised of the points should be below the rabbet's rim groove.

Apply a thin layer glazing compound on the rabbet grooves and the edges of new glass. This will protect and seal the edges. Let it dry completely and cure.

Install the new window sash once 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 drying out or cracking due to the moisture it absorbs. Apply the coat using a brush or the tip of your putty knife, then use the chisel, or the back end of the putty knife to gently hammer the new sash and glazier's point into the grooves of the rabbet. Repeat this process in intervals of 10 inches all around the frame.

Putty

A baseball hit or a rock thrown in error, or a tree falling can cause a broken or cracked window pane. Fortunately, the majority of windows can be easily replaced by simply putting a brand new piece of glass in its the right place. The glass is held into the position with a tiny metal clip, called the glazier's point, and putty. This compound is also referred to as glazing compound.

After the sash has been put back in place it is possible to apply a silicone caulk to the glass. This will ensure that it doesn't get soiled or discolor over time.

Remove the glazing points in the rabbets. These are the grooves in the sash where the glass is. If they're difficult to cut out, try placing the hand tool, such as a heat gun to soften them before you do. When using a heat tool, be sure to avoid damaging the sash's railings and sash.

Make a bed for your new pane after removing the old putty and glazing points. Roll a piece of glazing compound between your hands, and form it to be about 1/2-inch thick. Place it into the rabbets where the glass will be placed. It is essential that the glass sits on the putty in all places on both sides If you have to, lightly tap the glass into the rabbet with your thumb.

When you are ready to begin with the removal of the window pane. Take out the metal glazing points that are attached to it. These are tiny metal triangles which act as "nails", holding the window in place. They are placed under a glaze putty or bead that sets to form solid wedge that holds the wood frame in place and hides the sharp edges.

After taking off the old pane clean the frame and wood. Scrape away any paint and sand down the rabbet grooves, where the glazing points were. Sand them down to bare wood surfaces, so that you can paint the frames the same shade. After sanding, apply a coat of flax oil to the wood that is not sanded down to help extend its lifespan.

Next, measure the size of the window opening. You'll need to take vertical and horizontal measurements of the entire opening as well as 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. You can take these measurements to a hardware or home improvement shop 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.
