It is recommended to do this on a sturdy ladder rather than on the ground and to place someone on the sash in order to help hold it steady.

Once you have removed all of the old putty, prepare the window frame to accommodate the new pane. Find the width and the height of the opening in the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to an hardware or home centers store to have a piece cut of glass stock to the proper size. Alternatively, you can cut the glass yourself if you have the tools you need.

After putting in the new pane, run a small bead of caulking around the edges to make it weatherproof. Then, place a glazier's tip on the frame's opposite side to secure the pane in its place. The points should not be too tight that they create friction between the frame and the sash however they should not be loose.

Before applying the putty to the surface, you must knead it thoroughly until it is soft and free from lumps. Then make it into pencil-sized strips. The first strip should be glued to the frame's corner. Work from one corner to the next 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 glass into frames for windows without scratching or damaging the delicate surface. It's simple to learn how to use this secret tool, and you'll save money on the cost of a professional installation.

After taking off the old putty, glazier points as well as any remaining residue clean the frame thoroughly using a utility knife. If needed you can lightly sand the wood in the grooves of the rabbet to smooth rough areas. If you sand wood protect it with painter's tape to avoid accidental damage.

Take the dimensions of the frame and note down precise measurements. 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 a tight fit and leave room for expansion and contraction.

Place the new window in the frame and press it into the frame using your hand. Then, you can use the point of your chisel or the back end of the putty knife to pierce the glazier's facets, as illustrated in Figure 11. When you're done, they should be in line with the top edge of the pane, and the raised shoulders of the points should be just below the lip of the rabbet groove.

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

Install the new window sash after the glazing compound has dried. First, coat the wood with a thick coat of Linseed oil. This will stop the new putty from drying out and cracking when it absorbs moisture. Apply the coating using a brush this coat, or even the tip of the blade. Then, use the chisel that is on the back of the putty tool or the back of the handle to gently hammer the new sash or glazier's point into the rabbet grooves. Repeat this procedure every 10 inches along the perimeter of the frame.

Putty

A baseball thrown at you, an errant rock or falling branch could cause a window pane to break or crack. The majority of windows can be repaired easily by installing a new piece. The glass is held in place using a small metal clip called the glazier's pointed and putty, which is often called glazing compound. Remove the old pane and clean the area using a rag, a pull-type scraper or wood chisel. Wear gloves and safety glasses while you do this work. If the window handles replacement is secured to the frame, you'll have to make use of a heat gun to soften the adhesive before taking it off.

If you're planning to Replace Window Pane the original sash, take off the mold that holds the old pane. Then sand the sash to ensure it's smooth and ready to be re-caulked. After the sash has been reinstalled it is possible to apply a silicone caulk over the glass. This will ensure that it doesn't be leaking or fade over time.

Take the glazing points out of the rabbets, or the grooves in the sash, where the glass sits. If they're difficult to chisel, use the hand tool, such as a heating gun over them to soften first. When using a heated tool, be sure to avoid damaging the sash and its railings.

Once the old points of glazing and putty have been removed prepare a bed for the new pane. Roll a rope of glazing compound between your hands, shaping it to be about 1/2-inch thick. Then, press it into the rabbets, where the glass will sit. It's important that the glass sits on the putty on both sides If you have to tap it, gently press the glass into the rabbet with your thumb.

If the new pane is cracked, you can use the silicone caulk or glass glue based on solvents to seal the crack prior to pressing it in the sash. In other cases, you'll need to apply putty over the crack to form a tight seal and keep water out.

They are buried beneath a glaze putty or bead that hardens to a solid wedge that holds the wood frame securely in place and conceals the edges.

After you have removed the old pane removed clean the surrounding 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 bare wood, to allow you to paint them the same color as the rest the frame. After the sanding process, apply a coat of flax oil on the wood's surface to extend the life of the frame.

Next, measure the size of the window opening. You'll need to determine the horizontal and vertical dimensions of the entire opening as well as the thickness. Subtract 1/8 inch from each measurement to ensure that you have the exact size for the new pane. This will also allow for expansion and contraction of the glass during seasons of changes. You can take 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.
