This should be done on a ladder, not on the ground. Also, have someone on the ground to keep it in place.

Prepare the window frame to receive the new pane when you have removed the old glue. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of width and height. These measurements can be taken to a home center or hardware store to have an item cut from glass that is in stock to the correct size. Alternatively, you can cut the glass yourself, if you have the right tools.

After installing the new pane after installing the new pane, put a tiny amount of caulking around the edge to make it weatherproof. Install a glazier's point on both sides of the frame. This will ensure the pane. The points shouldn't be tight enough to create friction between the frame and sash however they should not be loose.

Before applying the putty on the surface, you must knead it thoroughly until it becomes soft and free of lumps. Then you can roll it into pencil-sized strips. Place the first strip to the corner of the frame, moving from one corner to another so that it is smooth and even.

Glazier's Points

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

If you decide to sand the wood, ensure you protect it with painter's tack to avoid accidental damage.

Note down the exact dimensions of the frame. Take these dimensions to an hardware store or home center and have the new pane cut smaller than the frame's opening. This will ensure a snug fit and leave room for expansion and contraction.

Place the new pane into the frame and push firmly using your hands. Then, use the tip of your chisel, or the back of the putty knife to tap in the glazier's points as illustrated in Figure 11. The glazier's points should be flush against the top edge of the pane and the shoulders raised should be just beneath that lip.

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

Install the new window sash once the glazing compound has dried. First, coat the wood with a heavy coat of linseed oil. This will prevent the new putty from soaking in the moisture and deteriorating and cracking over time. Apply this coat using a brush or the edge of your putty knife, then employ the chisel or back end from the putty knife to gently press the new sash and glazier's points into the grooves of the rabbet. Repeat this process every 10 inches around the frame's perimeter.

Remove the old pane and clean the area using a rag, a pull-type scraper or wood chisel. Wear safety glasses and gloves while you do this work. If the window is attached to the frame, you'll have to use a heat gun to soften the adhesive before prying it free.

If you're planning to install the original sash, remove any pieces of molding that hold the old pane in place. Then sand the sash to ensure it's level and ready for a new caulk. After the sash has been installed it is possible to apply a silicone caulk on the glass. This will ensure that it won't be leaking or fade over time.

Take out the glazing points in the rabbets. These are the grooves on the sash where the glass is located. If they are hard to cut, place the hand tool, like a heat gun over them to soften first. If you're using a heated gun, be cautious 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 by removing the old glaze points and putty. Roll a rope with glazing compound between your fingers and make it around 1/2 inch thick.

It is essential that the glass sits on the putty in all places on both sides, so if you need to, lightly tap the glass into the rabbet using your thumb.

If the new pane has a crack you can fill it with a solvent-based glass glue or silicone caulk before pressing it into the sash.

They are submerged beneath a glaze putty or bead that sets to form a solid wedge which holds the wood frame in place and conceals the edges.

After removing the old pane, clean the frame and wood. Scrape away any paint and sand down the rabbet grooves where the glazing points used to be. These should be sanded down to the point of being bare, so that you can paint them the same shade as the rest of the frame. After the sanding process, apply a coat of flax oil to the wood that is not sanded down to extend the life of the frame.

The next step is to measure the dimensions of the window and door replacement's opening. You'll need to take vertical and horizontal measurements of the entire opening, and also the thickness of the old 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.
