It is best to do this using a sturdy ladder rather than the ground, and to have someone standing below the sash in order to help hold it steady.

Make sure that the window frame is ready to accept the new pane after you have removed the old glue. Take measurements of the width and height of the sash opening, subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to a hardware store or home center and have a piece of stock glass cut to size. You can cut the glass yourself if you possess the right tools.

After putting the new pane in place After installing the new pane, apply a small amount of caulking around the edge to seal it against weather. Install a glazier’s point on both sides of the frame. This will ensure the pane. The points shouldn't 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, knead thoroughly until it becomes soft and free of lumps. Make it into pencil-sized strips. The first strip should be glued to the frame's corner. Work from corner to corner and ensure that it is even and smooth.

Glazier's Points

If you do sand your wood, be sure to protect it with painter's tack to avoid accidental damage.

Take measurements of the empty frame and write down accurate measurements. Take these measurements to a hardware store or a home center and have the new pane made slightly smaller than the frame's opening. This will ensure a snug fit and leave room for expansion and contraction.

Place the new pane into the frame and press it in place by using your hands. Use the point of the chisel or the edge of the putty blade to smudge the glaziers' points as shown in Figure 11. After you're done, the points should be in line with the top edge of the pane, and the shoulders that are raised of the points should be just below the rabbet's lip. groove.

Apply a small amount 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.

Install the new window sash when the glazing compound has dried. The first step is to coat the wood with an even layer of linseed. This will stop the new putty drying out or cracking when it absorbs moisture. Use a brush to apply this coat, or the point of the putty blade.

Putty

A baseball thrown at you or a rock that is errant or a falling branch can cause a window pane to break or crack. Luckily, most windows can be repaired by simply placing a new piece in the proper place. The glass is held in the position with a tiny metal clip, also known as a glazier’s point and putty.

These are tiny metal triangles that function as "nails", holding the window within the frame. They are submerged beneath a bead or glazing glue which hardens into solid wedge which holds the wood frame firmly in position and hides the sharp edges.

After taking off the old pane clean the frame and wood. Scrape away any old paint and sand down the rabbet grooves, Replace Window pane where the glazing points were. They should be sanded to bare wood, so that you can paint them the same shade as the rest of the frame. After sanding the wood you can apply a layer flax oil.

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.
