It is best to work on a sturdy ladder rather than on the ground, and to have someone standing below the sash to help keep it in place.

After you've removed all the old putty, you can prepare the window frame to accommodate the new pane. Find the width and the height of the opening in the sash, subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Bring these measurements to the nearest hardware store or home center and find a piece glass cut to size. Alternatively, you can cut the glass yourself if have the tools you need.

After putting the new pane in place, run a small bead of caulking along the edge to ensure it is weatherproof. Then, place a glazier's tip on the frame's opposite side to hold the pane in the right place. The points shouldn't be so tight that they cause friction between the sash and frame but they shouldn't be loose.

Before applying the putty to the surface, knead thoroughly until it becomes soft and free from lumps. Make it into pencil-sized strips. The first strip should be placed to the corner of the frame, working from one corner to the next so that it is smooth and even.

Glazier's Points

Place the new window in the frame and press it into the frame with your hand. 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, they should be flush with the top edge of the pane, and the shoulders of the points should be just below the rabbet's rim groove.

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

Once the glazing compound has dried, you're ready to install the new window sash. First, coat the wood with a thick coat of linseed oil.

After the sash has been re-installed, apply a new silicone caulk to the glass to ensure it will not leak or change color as time passes.

Take the glazing points out of the rabbets and the grooves in the sash that the glass sits. If they're difficult to work out, try holding the hand tool, such as a heat gun to soften them up first. If you're using a heat gun, be careful not to cause damage to the sash or its railings by using the tool too tightly.

Once the old points of glazing and putty have been removed make a bed for the new pane. Roll a rope with glazing compound between your fingers and make it around 1/2 inch thick.

They are placed under a bead or glazing putty that sets to form solid wedge that holds the wood frame in place and conceals the edges.

After taking off the old pane clean the frame and the wood. Scrape away any old paint and sand down the rabbet grooves, where the glazing points were. They should be sanded to the point of being bare, so that you can paint them the same shade as the rest of the frame. After the sanding process, apply a coat of flax oil on the wood that is not sanded down to extend the life of the frame.

The next step is to measure the dimensions of the window opening. You'll need to take horizontal and vertical 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 store or home improvement shop and have the glass cut for you.

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