Make sure the window frame is ready to receive the new pane once you have removed the old putty. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of the width and height. These measurements can be sent to a home center or hardware store to get an item cut from stock glass to the right size. You can also cut the glass yourself, if you have the right tools.

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

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

Glazier's Points

Write down the dimensions of the frame. Take these measurements to an hardware store or home center, and have the new pane made slightly smaller than the frame's opening. This will ensure that the pane fits comfortably and allows for expansion and contraction.

Insert the new pane into the frame and push it in using your hands. Then use the point of your chisel, or the back of the putty knife to make a tap on the glazier's points, as shown in Figure 11. After you're done, the points should be level with the top edge of the pane and the shoulders of the points should be just below the rabbet's lip. groove.

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

When the glazing compound is dry it's time to put in the new window sash. First, coat the wood with a thick layer of linseed. This will stop the new putty from drying out or cracking due to the moisture it absorbs. Use a brush to apply this coat, or the point of the putty blade. Then use the chisel that is on the back of the putty tool or the back of the handle to gently hit the new sash, or glazier's point into the grooves of the rabbet.

Putty

Once the sash is installed, you can apply a silicone caulk over the glass. This will ensure that it won't be leaking or fade over time.

Take the glazing points out of the rabbets and the grooves in the sash, where the glass is. If they're difficult to cut, place a hand tool such as a heatgun over them to allow them to soften before.

These are essentially small metal triangles which function as "nails" that keep the window in within the frame of wood. They are placed under a bead or glazing glue that hardens to solid wedge that holds the frame securely in place and conceals the edges.

After you have removed the old pane taken away, clean up the surrounding frame and wood. Scrape away any old paint and sand down the rabbet grooves where the glazing points were. These 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 then apply a layer of flax oil. This will help to prolong the life of the frame.

Then, take measurements of the dimensions of the window opening. You'll need to determine the vertical and horizontal dimensions of the entire opening, as well as the thickness. To determine the exact size of the new pane, subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass. Bring these measurements to the hardware or home improvement store, and they will have a piece cut for you.

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

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.
