Use a wood chisel, or putty knives to remove any old putty that remains around the frame and window sash. Be careful and slow, taking care not to break the current window sash. This can be done best on an elevated ladder, not on the ground. Also, ensure that someone on the ground to hold it steady.

Once you have removed all of the old putty, it is time to prepare the window frame for the new pane. Measure the width and height of the opening in the sash and subtract 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Bring these measurements to a hardware store or home center, and have a piece of stock glass cut to size. You can cut the glass yourself if you have the appropriate tools.

After installing the new glass Apply caulking around 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 that they create friction between the sash and the frame but they shouldn't be too loose.

Before applying the putty on the surface, you must knead it thoroughly until it becomes soft and free from lumps. Cut it into pencil-sized pieces. Apply the first strip in the corner of the frame, moving from one corner to the other so that it is even and smooth.

Glazier's Points

The glazier's points are small triangular metal pieces that help secure the glass to the frame without damaging the delicate surface. Understanding how to use these tiny helpers is simple and could save you money on professional installation or the cost of buying new glass.

Take the dimensions of the frame and write down accurate measurements. Bring these measurements to an hardware store or home center, and have the new pane cut smaller than the frame's opening. This will ensure that the pane fits snugly and allows for expansion and contraction.

Place the new pane in the frame and push it in using your hands. Then use the point of your chisel, or the back end of the putty knife to make a tap on the glazier's facets, as illustrated in Figure 11. When you're done taping, they should be flush with the top edge of the pane, and the raised shoulders of the points should be just below the rabbet's lip. groove.

Apply a thin layer of glazing compound on the edges of the new glass and in the rabbet grooves, to seal and protect them. Allow it to dry completely and cure.

After the glazing compound dries and the glazing compound is dry, you can install the new window sash. The first step is to coat the wood with an even layer of linseed. This will stop the new putty drying out or cracking as it absorbs moisture. Use a brush to apply this coat, or even the tip of the putty blade.

Putty

A baseball hit or a rock thrown by error or a branch falling could result in a broken or cracked window pane.

The glass is held into the position with a tiny metal clip, called the glazier's point, and putty. This compound is also referred to as glazing compound.

Once the sash is reinstalled it is possible to apply a silicone caulk to the glass. This will ensure that it won't be leaking or fade over time.

Remove the glazing points from the rabbets and the grooves in the sash where the glass is. If they're difficult to cut out, try holding the hand tool, such as a heat gun over them to soften them up first. When using a heated tool, be sure to avoid damaging the sash and its railings.

Create a bed for your new pane by 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. Place it into the rabbets, where the glass will be placed. The glass must be positioned against the putty on both sides. If necessary, lightly tap your glass into the rabbet using your thumb.

If the new pane is cracked, you can apply the silicone caulk or glass glue based on solvents to seal the crack prior to pressing it in the sash.

After you have removed the old pane removed, clean up the surrounding frame and wood. Scrape off any paint that has been used and sand down the rabbet grooves where the glazing points were placed. Sand them to bare wooden surfaces so you can paint the frames with the same shade. After sanding the wood, apply a layer of flax oil. This will help to extend its life.

The next step is to measure the dimensions of the window's 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 also allow for expansion and contraction of the glass during seasons of change. Take these measurements to a hardware or home improvement store and ask them to cut you a piece 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.

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.
