Take these measurements to an hardware store or home center and get a piece of stock glass cut to size. You can cut the glass yourself if you possess the right tools.

After installing the new glass, apply some caulking to the edge. This will make the glass weatherproof. Install a glazier's point on both sides of the frame. This will ensure the pane. The points shouldn't be too tight that they cause friction between the frame and the sash, but they should also not be loose.

Before putting the putty on, knead it thoroughly until it's soft and free of lumps. Then you can roll it into pencil-sized strips. Place the first strip in the corner of the frame, moving from one corner to another so that it is even and smooth.

Glazier's Points

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

Once the old putty and the glazier's points have been removed Clean the frame thoroughly with a utility knife to remove any remaining residue. If needed, lightly sand the wood along grooves of the rabbet to smooth rough areas. If you decide to sand the wood, make sure to protect it with painter's tack to avoid accidental damage.

Write down the dimensions of the frame. These dimensions can be taken to a home center or hardware store, and the new pane will be cut a bit smaller. This will ensure that the pane fits snugly and allows for expansion and contraction.

Place the new pane in the frame and push it into place firmly with your hand. Make use of the point of the chisel, or the back of the putty blade to tap in the glazier's points, as illustrated in Figure 11. When you're done, they should be level with the top edge of the pane. the shoulders that are raised of the points should be just below the rabbet's rim groove.

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

Install the new window sash once the glazing compound has dried. First, coat the wood with a heavy coat of linseed oil. This will stop the new putty from sucking up moisture and deteriorating and cracking with time. Apply this coat with a brush or the edge of your putty knife, and then use the chisel, or the back end of the knife to gently hammer in the new sash and glazier's point into the grooves of the rabbet.

Once the sash is re-installed then, apply a new caulk made of silicone around the glass to ensure it will not leak or change color over time.

Remove the glazing points from the rabbets. These are the grooves on the sash where the glass is located. If they're difficult to chisel, hold an instrument like a heat gun over them to allow them to soften before. If you're using a heating gun, be careful not to cause damage to the railings of the sash or the sash itself by holding the tool too closely.
