Make use of a wood chisel or putty knives to remove any remaining old putty around the frame and window sash. Work slowly and carefully and be careful not to break the existing window sash. It is recommended to work on a stable ladder rather than the ground and to place someone on the sash to help keep it steady.

Prepare the window frame to receive the new pane after you have removed the old glue. To allow for seasonal expansion or contraction, subtract 1/8 inch each from the measurements of the width and height. Bring these measurements to the nearest hardware store or home center, and find a piece glass cut to size. You can cut the glass yourself if you have the right tools.

After putting in the new glass, apply some caulking on the edges. 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 the frame but they should not be too loose.

Before applying the putty on the surface, gently knead it until it is smooth and free of lumps. Make it into pencil-sized strips. The first strip should be placed in the corner of the frame, working from one corner to the other to ensure it is smooth and even.

Glazier's Points

The glazier's points are tiny triangular metal pieces that allow glass to be secured to the frame without causing damage to the delicate surface. It's easy to learn how to use this nefarious tool and you can save money on the cost of an installation by a professional.

Insert the new pane into the frame and push firmly with your hands. Make use of the point of the chisel, or the edge of the putty blade to tap the glazier's points, as shown in Figure 11. The glazier's points should be flush against the top edge of your pane and the raised shoulders should be just beneath that lip.

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

Install the new window sash once the glazing compound has dried. First, you need to coat the wood with an even layer of linseed. This will stop the new putty from taking up the moisture and drying out and cracking with time. Apply this coat with a brush or the edge of your putty knife, then use the chisel or the back end of the putty knife to gently press the new sash and glazier's tips into the rabbet grooves. Repeat this process every 10 inches around the frame's perimeter.

Putty

A baseball thrown or a rock thrown in error, or a tree falling can cause a broken or cracked window pane. Fortunately, the majority of windows can be repaired by simply putting a brand new piece in place. The glass is held in place using tiny metal clips known as a glazier's point, and putty, often called glazing compound. Remove the old pane and clean the area with an abrasive, pull-type scraper, or a wood chisel. Wear safety glasses and gloves while working. If the window is attached to the frame, you'll need employ a heat gun in order to soften the adhesive before taking it off.

If you plan to reinstall the original sash, remove any pieces of molding that are used to secure the old pane. Sand the sash until it is flat and ready to receive new caulk. Once the sash is re-installed and sanded, apply a fresh silicone caulk around the glass to ensure it won't leak or discolor in time.

Remove the glazing points from the rabbets. These are the grooves in the sash where the glass is located. If they're hard to chisel out, try placing an instrument like a heat gun to soften them before you do. When using a heat tool, be sure to not damage the sash and its railings.

Make a bed for your new pane after you have removed the old putty and glazing points. Roll a rope with glazing compound between your fingers and then make it about 1/2 inch thick. Then, you can press it into the rabbets where the glass will be. It is essential that the glass sits on the putty on each side So if you have to tap it, gently press the glass into the rabbet using your thumb.

If the new pane has cracked, you can use a silicone caulk or glass glue that is based on solvents to seal the crack before pressing it into the sash. If the crack is not sealed, you'll require putty to keep water out. When the putty dries, clean the oily film off the glass with the help of a rag. Allow it to completely dry before painting. If you paint before the putty is fully dry, it won't create a solid seal and could discolor or leak in time.

Paint

They are buried beneath a bead or glazing putty that hardens to solid wedge that holds the wood frame firmly in position and conceals the edges.

After removing the old pane, clean the frame and wood. Scrape away any old paint and sand down the rabbet grooves, where the glazing points were. These should be sanded down to bare wood to allow you to paint them the same shade as the rest of the frame. After sanding the wood you can apply a layer flax oil. This will help to prolong the life of the frame.

The next step is to measure the dimensions of the window double glazing replacement opening. It is necessary to measure 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. You can take these measurements to a hardware store or home improvement store and have 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.
