Utilize a wood chisel or putty knives to remove any old putty remaining around the frame and window sash. Be careful not to damage the window sash. Be careful and slow. This should be done on a ladder, not the ground. Also, have someone below the sash keep it in place.

Prepare the window frame to accommodate the new pane after you have removed the old glue. Find the width and the height of the opening in the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to a home center or hardware store to get an item cut from glass stock to the proper size. Alternately, you can cut the glass yourself if have the appropriate tools.

After putting the new pane in place After installing the new pane, apply a small amount of caulking around the edge to ensure it is weatherproof. Then, you can install a glazier's pointing on each side of the frame to secure the pane in place. The points shouldn't be tight enough to cause friction between the frame and sash however they should not be loose.

Before applying the putty on the surface, gently knead it until it becomes soft and free from lumps. Then you can roll it into pencil-sized strips. The first strip should be glued to the corner of the frame. Work from one corner to another, making sure it is even and smooth.

Glazier's Points

The glazier’s points are small triangular metal pieces which help to secure the glass into the window frame without causing damage to the delicate surface. Knowing how to use these little helpers is easy and could save you money on professional installation or the cost of buying new glass.

Note down the exact dimensions of the frame. Take these dimensions 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 secure fit, and allow for expansion and contraction.

Place the new pane in the frame and push it in with your hands. Then, you can use the point of your chisel or back end of the putty knife to tap in the glazier's points, as shown in Figure 11. When you're done, they should be level with the top edge of the pane, and the shoulders that are raised of the points should be below the rabbet's lip. groove.

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

After the glazing compound dries, you're ready to install the new window sash. First, coat the wood with a thick coat of Linseed oil. This will stop the new putty from drying out or cracking due to the moisture it absorbs. Apply this coat using a brush or the tip of your knife, then use the chisel, or the back end from the putty knife to gently press the new sash and glazier's points into the rabbet grooves. Repeat this process in intervals of 10 inches around the frame.

Remove the glazing points from the rabbets, 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. When using a heat tool, be sure to not damage the sash or its railings.

Make the bed for your new pane after removing the old glaze points and putty. Roll a piece of glazing compound between your hands, and form it into a 1/2-inch thick. Then, you can press it into the rabbets where the glass will be. The glass should rest against the putty on both sides. If you need to you want to tap your glass lightly into the rabbet with your thumb.

If the new pane has damaged, you can use a silicone caulk or a glass glue that is based on solvents to fill in the crack before pressing it into the sash. Otherwise, you'll need to putty over the crack to form an impervious seal to keep water out.

After you have removed the old pane taken away, clean up the surrounding frame and replace window Pane wood. Scrape off any old paint, and sand the rabbet grooves in which the glazing points were placed. Sand them down to clean wooden surfaces so you can paint the frames with the same shade. After sanding, apply a coat of flax oil to the bare wood to extend the life of the frame.

Next, measure the width of the window opening. It is necessary to measure the vertical and horizontal dimensions of the entire opening as well as the thickness. To get the exact size of the new pane subtract 1/8 inch from both measurements. This will also allow for expansion and contraction of the glass during seasons of change. Take these measurements to the hardware or home improvement store, and Replace window pane 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.
