This can be done best on a ladder, not the ground. Also, have someone lower to keep it in place.
Prepare the window frame to receive the new pane once you have removed the old putty. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of width and height. Take these measurements to a hardware store or home center and have a piece of stock glass cut to size. You can also cut the glass yourself if you have the right tools.
After putting the new pane in place, run a small bead of caulking along the edge to ensure it is weatherproof. Then install a glazier's point on each side of the frame to hold the pane in its place. The points should not be so tight that they cause friction between the frame and sash however they should not be loose.
Before putting the putty on, knead it thoroughly until it is soft and free of lumps. Then make it into pencil-sized strips. Apply the first strip to the corner of the frame. Work from corner to corner and ensure that it is even and smooth.
Glazier's Points
The glazier's points are small triangular pieces of metal which help to secure the glass to the frame without damaging the delicate surface. It's simple to learn how to use this hidden tool, and you'll save money on the cost of a professional installation.
After the old putty as well as glazier's points are removed and the frame is thoroughly cleaned using a utility knife to get rid of any remaining residue. Lightly sand the wood in the rabbet grooves if needed to smooth rough areas. If you decide to sand wood, protect it with painter's tape to prevent accidental damage.
Write down the exact dimensions of the frame. These dimensions can be taken to an hardware or home centers store, and the new pane will be cut to a smaller size. 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 place by using your hands. Utilize the chisel's point or the back of the putty knife to tap in the glazier's points, as illustrated 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 thin layer glazing compound on the rabbet grooves as well as the edges of the new glass. This will seal and protect the edges. Let it dry and cure completely.
Once the glazing compound has dried and the glazing compound is dry, you can install the new replacement window pane sash. The first step is to coat the wood with an even layer of linseed. This will prevent the newly-created putty drying out or cracking due to the moisture it absorbs. Apply this coat with a brush or the tip of your knife, then employ the chisel or back end of the putty knife to gently hammer in the new sash and glazier's tips into the grooves of the rabbet. Repeat this process every 10 inches around the perimeter of the frame.
Putty
A hurled baseball, an errant rock or a falling branch can cause a window pane to crack or break. Most windows glasses replacement can be replaced by putting in a new piece. The glass is held in place using 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 with the rag, a pull-type scraper or wood chisel. Wear protective glasses and gloves while working. If the window is glued to the frame, you'll need make use of a heat gun to soften the adhesive prior to prying it free.
If you're planning to install your original sash, remove the molding that holds the old pane. Then, sand the sash to ensure it's level and ready for new caulk. After the sash has been put back in place then, you can apply a silicone caulk on 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 that the glass sits. If they're hard to chisel out, try placing a hand tool like a heat gun over them to soften them up first. If you're using a heat gun, be cautious not to damage the railings of the sash or the sash itself by using the tool too close.
Once the old glaze points and putty are removed, prepare a bed for the new pane. Roll a rope with glazing compound between your fingers, and make it around 1/2 inch thick. Then, you can press it into the rabbets, where the glass will sit. It's important that the glass sits on the putty in all places on both sides If you have to, lightly tap the glass into the rabbet using your thumb.
If the new pane is cracked, you can apply a silicone caulk or a glass glue based on solvents to fill in the crack before pressing it into the sash. If the crack is not sealed, you will need to use putty to keep water out. After the putty has dried remove the oily film off of the glass and allow it to dry completely before you paint.

If you're ready to begin with the removal of the old window pane by prying out the glazing points of metal that are attached to it. These are tiny triangles of metal which act as "nails", holding the window in place. They are placed under a bead or glazing putty that sets to form an unbreakable wedge which holds the wood frame securely in place and hides the points.
After removing the old pane, clean the frame and the wood. Scrape off any old paint and sand down the rabbet grooves that the glazing points were. These should be sanded down to the point of being bare, to allow you to paint them the same shade as the rest of the frame. After sanding, apply a coat of flax oil on the wood's surface to prolong its life.
Then, take measurements of the dimensions of the Window double glazing replacement opening. You'll need to take vertical and horizontal measurements of the entire opening as well as the thickness of the old pane.

Now, it's time to bed the new window pane.

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.
