Make sure that the window frame is ready to accommodate the new pane when 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 an hardware store or home center, and find a piece glass cut to size. Alternately, you can cut the glass yourself if have the tools you need.

After putting in the new glass, apply caulking on the edges. This will make the glass weatherproof. Then, place a glazier's tip on each side of the frame to secure the pane in its place. The points should not be so tight that they create friction between the sash and frame, but they also should not be too loose.

Before applying the putty, work it in a gentle manner until it is soft and free of lumps. Then you can roll it into pencil-sized strips. The first strip should be placed in the corner of the frame, working from one corner to the next so that it is even and smooth.

Glazier's Points

The glazier's points are tiny triangular pieces of steel that help secure the glass into the window frame without causing any damage to the fragile surface.

If you sand wood, cover it with painter's tape to protect it from damage caused by accidental sanding.

Measure the empty frame's dimensions and write down accurate measurements. These dimensions can be taken to an hardware or home centers store, and the new frame will be cut to a smaller size. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Place the new pane into the frame and press it down with your hands. Then use the point of your chisel or back of the putty knife to tap in the glazier's points as shown in Figure 11. The glazier's point should be flush against the top edge of your pane and the shoulders should be just below that lip.

Apply a thin bead of glazing compound over the edges of the new glass and into the rabbet grooves, to seal and protect them. Allow it to dry and cure fully.

Install the new window sash once 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 from soaking up moisture and deteriorating and cracking over time.

Remove the old pane and clean the area using the rag, a pull-type scraper, or a wood chisel. Wear protective glasses and gloves while working. If the window is secured to the frame, you'll need to employ a heat gun in order to soften the adhesive before prying it free.

If you plan to reinstall the original sash in the future, take care to remove the molding pieces that are used to secure the old pane. Then, sand the sash to make sure it's flat and ready to be re-caulked. After the sash has been installed it is possible to apply a silicone caulk to the glass. This will ensure that it won't get soiled or discolor over time.

Take the glazing points out of the rabbets, or the grooves in the sash, where the glass is. If they're hard to chisel out, try holding a hand tool like a heat gun over them to soften them first. If you're using a heated gun, make sure not to cause damage to the railings of the sash or the sash itself by holding the tool too close.

Create the bed for your new pane after removing the old glaze and putty. Roll a rope of glazing compound between your hands, forming it to be about 1/2-inch thick. Then, push it into the rabbets, where the glass will rest. It is crucial that the glass is positioned against the putty on each side, so if you need to do so, gently tap the glass into the rabbet with your thumb.

If the new pane has a crack then you can seal it with a solvent-based glass glue or silicone caulk prior to pressing it into the sash. If the crack isn't sealed, you'll require putty to keep water out. When the putty dries then clean the oily film off the glass using a rag and allow it to dry completely before painting. Paint before the putty has dried completely. It won't create a solid seal and may be leaking or discoloring over time.

After removing 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. These should be sanded down to bare wood to allow you to paint them the same color as the rest the frame. After the sanding process, apply a coat of flax oil to the wood's surface to extend the life of the frame.

Next, measure the dimensions of the window's opening. You will need to measure the horizontal and vertical dimensions of the entire opening as well as the thickness. Subtract 1/8 inch from each measurement to ensure that you get the exact measurement for the new pane. This will also allow for expansion and contraction of the glass during seasons of changes. You can bring these measurements to a hardware or home improvement shop and get the glass cut for you.

Now, it's time to bed the new window pane. To do this, place the pane inside the frame and move it around until a 1/16 inch of putty remains between the edge of the glass and the sash on all four sides. Use a putty knife to smear the putty evenly, making sure that there isn't an excessive amount of excess putty in the corners and along the edges. 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.
