Be careful and slow making sure not to break the current window sash. It is best to work on a sturdy ladder rather than on the ground and have someone stand below the sash to help keep it steady.

Once you have removed all of the old putty, you can prepare the window frame to accommodate the new pane. Take measurements of the width and height of the opening for the sash, subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to a home center or Replace window pane hardware store to get an item cut from glass that is in stock to the correct size. You can cut the glass yourself if you possess the appropriate tools.

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 shouldn't be so tight as to cause friction between the sash and frame but they should not be too loose.

Before applying the putty to the surface, you must knead it thoroughly until it becomes soft and free of lumps. Cut it into pencil-sized pieces. The first strip should be glued to the frame's corner. Work from corner to corner to ensure it's even and smooth.

Glazier's Points

The glazier’s points are small triangular metal pieces that allow glass to be secured to the frame without causing any damage to the fragile surface. It's simple to learn how to use this secret tool and you can save money on the cost of an expert installation.

After getting rid of the old putty glazier points as well as any remaining residue Clean the frame thoroughly using a utility knife. If necessary it is necessary to lightly sand the wood along the rabbet grooves to smooth out rough areas. If you sand wood cover it with painter's tape to avoid accidental damage.

Measure the empty frame's dimensions and write down accurate measurements. Take these measurements to an hardware store or home center and have the new pane cut smaller than the frame's opening. This will ensure a tight fit, and allow for expansion and contraction.

Place the new pane into the frame and press it into the frame by using your hands. Utilize the point of the chisel, or the back of the putty knife to tap the glazier's points, as illustrated in Figure 11. When you're done, they should be flush with the top edge of the pane and the shoulders that are raised of the points should be just below the rabbet's rim groove.

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

Install the new window sash after the glazing compound has dried. First, coat the wood with a heavy coat of Linseed oil. This will prevent the new putty from drying out and cracking due to the moisture it absorbs.

The glass is held in place by a small metal clip, also known as a glazier’s point and putty. This compound is also referred to as glazing compound.

Once the sash is installed then, you can apply a silicone caulk to the glass. This will ensure that it doesn'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 are hard to chisel, use the hand tool, such as a heatgun over them for a few minutes to soften them. When using a heated tool, be careful to avoid damaging the sash and its railings.

Prepare the bed for your new pane by removing the old glaze and putty. Roll a piece of glazing compound between your hands, shaping it to be about 1/2-inch thick.

Sand them to bare wooden surfaces so you can paint the frames with the same color. After sanding the wood you can apply a layer flax oil. This will help to prolong the life of the frame.
