This can be done best on an elevated ladder, not on the ground. Also, ensure that someone lower to hold it steady.

Once you've removed all the old putty, prepare the window frame for the new pane. Take measurements of the width and height of the opening in the sash, subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to the nearest hardware store or home center, and have a piece of stock glass cut to size. You can also cut the glass by yourself if you have the right tools.

After putting in the new glass Apply some caulking around the edge. This will make the glass weatherproof. Install a glazier’s point on both sides of the frame. This will help secure the pane. The points shouldn't be too tight that they cause friction between the frame and the sash however they should not be loose.

Before putting the putty on, knead it thoroughly until it's soft and free of lumps. Then, roll it into pencil-size strips. Apply the first strip in the corner of the frame, moving from one corner to the next so that it is even and smooth.

Glazier's Points

The glazier’s points are small triangular metal pieces which help to secure the glass to the frame without causing damage to the delicate surface. It's simple to learn how to use this hidden tool, and you'll be able to save money on the expense of an installation by a professional.

After taking off the old putty, glazier points as well as any remaining leftovers, clean the frame thoroughly using a utility knife. Lightly sand the wood in the rabbet grooves, if necessary, to smooth out rough areas. If you sand wood protect it with painter’s tape to prevent accidental damage.

Note down the dimensions of the frame. Bring these measurements to a hardware store or home center, and glass Replacement windows have the new pane cut slightly smaller than the frame's opening. This will ensure that the pane fits comfortably and allows for expansion and contraction.

Place the new pane into the frame and press it down using your hands. Use the point of the chisel or the back of the putty blade to tap the glazier's points as illustrated in Figure 11. When you're done taping, they should be flush with the top edge of the pane and the shoulders of the points should be below the lip of the rabbet groove.

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

Install the new window sash when the glazing compound has dried. First, saturate the wood with a thick coat of Linseed oil. This will prevent the newly-created putty drying out or cracking due to the moisture it absorbs. Use a brush to apply this coat, Glass replacement windows or the tip of the putty blade. Then, use the chisel that is on the back of the putty tool or the back of the putty handle to gently hit the new sash, or glazier's tip into the rabbet grooves.

Putty

A baseball hit or a rock thrown in error, or a fallen tree can result in a cracked or cracked window pane. The majority of windows can be replaced easily by installing a new piece. The glass is held in place with a small metal clip called a glazier's point, and putty, which is often called glazing compound. Remove the old pane and clean the area using the rag, a pull-type scraper, or a wood chisel. Wear safety glasses and gloves while you do this work. If the window is glued to the frame, you'll have to use a heat gun to soften the adhesive before taking it off.

If you plan to reinstall the original sash, remove any molding pieces that are used to secure the old pane. Sand the sash until it's flat and ready to receive new caulk. Once the sash is re-installed then, apply a new silicone caulk around the glass to ensure that it will not leak or change color in time.

Take the glazing points out of the rabbets and the grooves in the sash where the glass sits. If they're difficult to work out, try holding a hand tool like a heat gun to soften them first. When using a heat tool, be sure to not scratch the sash's railings and sash.

After the old glaze points and putty have been removed, prepare a bed for the new pane. Roll a piece of glazing compound between your hands, and form it to be around 1/2-inch thick. Then, push it into the rabbets in which the glass will sit. The glass must rest against the putty on both sides. If necessary gently tap your glass into the rabbet using your thumb.

If the new pane has a crack, you can cover 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 need to apply putty to keep water out. When the putty dries, clean the oily film off the glass with a rag and allow it to dry completely prior to painting.

These are tiny metal triangles which act as "nails", holding the window in the frame. They are placed under a bead of glazing putty, which is then cured to form a solid, formed wedge that holds the window firmly in place and conceals the points.

After removing the old pane, clean the frame and wood. Scrape off any old paint and sand down the rabbet grooves in which the glazing points were placed. Sand them down to clean wooden surfaces so you can paint the frames the same shade. After sanding the wood you can apply a layer flax oil. This will help extend its life.

The next step is to determine the size of the window opening. It is necessary to measure the horizontal and vertical 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 allow for seasonal changes in the glass. You can bring these measurements to a hardware store 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.
