To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of the width and height. Take these measurements to a hardware store or home center, and find a piece glass cut to size. You can also cut the glass yourself, if you have the tools you need.

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 cause friction between the frame and sash, but they should also not be loose.

Before putting the putty on, make sure to knead it until it's soft and free of lumps. Then, roll it into pencil-size strips. Apply the first strip to the frame's corner. Work from one corner to another, making sure it is even and smooth.

Note down the dimensions of the frame. These measurements can be brought 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 window in the frame and push it into the frame using your hand. Utilize the chisel's point, or the back of the putty knife to tap the glazier's points as illustrated in Figure 11. The glazier's point should be flush against the top edge of your pane, and the shoulders raised should be just below the lip.

These are basically small metal triangles that act as "nails" that keep the window in place in the wood frame. They are placed under a bead of glazing putty, which is then cured to form a solid, formed wedge which holds the window in place and conceals the points.

After taking off the old pane clean the frame and wood. Scrape off any paint that has been used, and sand the rabbet grooves in which the glazing points were. These should be sanded to bare wood, so that you can paint them the same color as the rest the frame. After sanding the wood, apply a layer of flax oil. This will help extend its life.

The next step is to measure the dimensions of the window opening. You will need to take vertical and horizontal measurements of the entire opening and also the thickness of the old pane.
