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

After you have removed all of the old putty, prepare the window frame to fit the new pane. To allow for seasonal expansion or contraction, subtract 1/8 inch each from the measurements of width and height. These measurements can be taken to a home center or hardware store to get cut a piece of glass that is in stock to the correct size. You can cut the glass yourself if you possess the appropriate tools.

After putting in the new pane after installing the new pane, put a tiny amount of caulking around the edge to ensure it is weatherproof. Then install a glazier’s point on the frame’s opposite side to secure the pane into its place. The points shouldn’t be too tight that they cause friction between the frame and the sash however they should not be loose.

Before applying the putty to the surface, knead thoroughly until it is smooth and free of lumps. Then make it into pencil-sized strips. The first strip should be glued to the frame’s corner. Work from one corner to another to ensure it’s even and smooth.

Measure the empty frame’s dimensions and write down accurate measurements. These dimensions can be taken to a home center or hardware store, and the new pane will be cut slightly smaller. This will ensure a tight fit and leave room for expansion and contraction.

Place the new pane into the frame and push it into place firmly with your hand. Utilize the point of the chisel, or the back of the putty blade to tap the glazier’s points as shown in Figure 11. When you’re done, they should be flush with the top edge of the pane and the shoulders that are raised of the points should be just below the lip of the rabbet groove.

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

Install the new window sash after the glazing compound has dried. First, saturate the wood with a thick coat of Linseed oil. This will stop the new putty from soaking up the moisture and deteriorating and cracking over time. Apply the coating using a brush this coat, or the tip of the putty blade. Then, use the chisel that is on the back of the tool or the back of the handle to gently hammer the new sash or glazier’s point into the grooves of the rabbet.

A baseball that is thrown or a rock that is errant or falling branch could cause a window pane to break or crack. The majority of windows can be repaired easily by simply putting in a fresh piece. The glass is held into the position with a tiny metal clip, also known as a glazier’s point and putty. This compound is also referred to as glazing compound. Remove the old pane and clean the area using a rag, a pull-type scraper, or a wood chisel. Wear safety glasses and gloves while doing this work. If the window is secured to the frame, you’ll have to use a heat gun to soften the adhesive before cutting it loose.

After the sash has been installed then, you can apply a silicone caulk to the glass. This will ensure that it doesn’t get soiled or discolor over time.

Remove the glazing points from the rabbets and the grooves in the sash, where the glass sits. If they’re hard to chisel, use a hand tool such as a heatgun over them to soften first. If you’re using a heating gun, be careful not to scratch the railings or sash by using the tool too tightly.

Make a bed for your new pane after removing the old glaze and putty. Roll a rope made of glazing compound between your fingers, and make it about 1/2 inch thick. Press it into the rabbets, where the glass will be placed. The glass must be positioned against the putty on both sides.

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

After you have the old pane removed, clean up the surrounding frame and wood. Scrape off any old paint, and sand the rabbet grooves in which the glazing points were. Sand them to bare 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 to extend its life.

The next step is to determine the width of the window’s opening. It is necessary to measure the horizontal and vertical dimensions of the entire opening, as well as the thickness.
