The procedure of replacing a window pane is relatively easy and can be completed by most homeowners who possess basic hand tools. In addition to a new pane, the following items are needed: latex glazing putty; Glazier’s points; pliers and the use of a heat gun to warm the old putty, if necessary. Before starting, wear gloves and safety glasses as working with broken glass can cause injuries.

Begin by removing any remaining broken pieces of glass. It is best to use pliers, but a flathead can be used equally. Then, use a wood chisel, or putty knife, to remove the rest of the old putty from the frame and the sash. Be careful to not damage the window sash. Take your time and work slowly. This should be done on an elevated ladder, not on the ground. Also, ensure that someone on the ground to keep it in place.

Prepare the window frame to accept the new pane once you have removed the old glue. Find the width and the height of the opening for the sash, subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to a hardware or home center store to have a piece cut of stock glass to the right size. You can cut the glass yourself if you have the right tools.

After putting in the new glass Apply a small amount of caulking around the edge. This will make the glass weatherproof. Install a glazier’s pointing on both sides of the frame. This will ensure the pane. The points shouldn’t be so tight that they cause friction between the frame and sash, but they also should not be too loose.

Before applying the putty to the surface, you must knead it thoroughly until it becomes soft and free of lumps. Make it into pencil-sized strips. The first strip should be glued to the corner of the frame. Work from one corner to another and ensure that it is even and smooth.

Glazier’s Points

The glazier’s facets are small triangular pieces that help secure glass into frames for windows without damaging or scratching the delicate surface. It’s easy to learn how to use this secret tool, and you’ll save money on the cost of an installation by a professional.

After removing the old putty, glazier points, and any other leftovers Clean the frame thoroughly with an utility knife. If necessary, lightly sand the wood along grooves of the rabbet to smooth out rough spots. If you sand wood cover it with painter’s tape to avoid accidental damage.

Write down the exact dimensions of the frame. These dimensions can be taken to a home center or hardware store and the new pane will be cut to a smaller size. This will ensure a tight fit and will allow room for expansion and contraction.

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

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

After the glazing compound dries and the glazing compound is dry, you can install the new window sash. The first step is to coat the wood with a thick coat of linseed oil. This will prevent the new putty from soaking up the moisture and deteriorating and cracking with time. Apply the coating using a brush this coat, or even the tip of the putty blade. Then, use the chisel 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. Repeat this process at intervals of 10 inches around the frame.

Putty

A hurled baseball or an unintentional rock, or a fallen branch can cause a window pane to break or crack. Luckily, most windows can be repaired by simply putting a brand new piece in the right place. The glass is held in place by a small metal clip called the glazier’s pointed and putty, which is often called glazing compound. Before installing a new pane, first get rid of the old one and clean the area using the help of a rag, the pull-type paint scraper or the wood chisel. Wear safety glasses and gloves while working. If the window is secured to the frame, you’ll need employ a heat gun in order to soften the adhesive before cutting it loose.

If you are planning to Replace window pane your original sash, you must remove the molding that supports the old pane. Then, sand the sash to ensure it’s smooth and ready to be re-caulked. After the sash has been re-installed then, apply a new silicone caulk to the glass to ensure it won’t leak or discolor over time.

Remove the glazing points from the rabbets, the grooves in the sash where the glass is. If they’re difficult to cut, place a hand tool such as a heating gun over them to soften first. If you’re using a heated gun, be cautious not to cause damage to the railings of the sash or the sash itself by placing the tool too tightly.

After 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 into a 1/2-inch thick. Then, you can press it into the rabbets, where the glass will sit. The glass should rest against the putty on both sides. If necessary gently tap your glass into the rabbet using your thumb.

If the new pane has damaged, you can use a silicone caulk or a glass glue based on solvents to fill in the crack prior to pressing it into the sash. If the crack isn’t sealed, you’ll need to use putty to keep water out. When the putty dries, clean the oily film off the glass with a rag and allow it to completely dry before painting.

When you are ready to begin, remove the old window pane. Pry out the metal glazing points that are attached to it. These are small metal triangles which act as “nails” to hold the window within the frame. They are placed under a bead or glazing putty which hardens into solid wedge that holds the frame securely in place and hides the sharp edges.

After you have the old pane taken away Clean up the frame and wood. Scrape off any old paint and sand down the rabbet grooves where the glazing points were placed. These should be sanded down to bare wood, to allow you to paint them the same color as the rest the frame. After sanding, apply a coat of flax oil on the wood’s surface to help extend its lifespan.

Next, measure the size of the window opening. You’ll need to take vertical and horizontal measurements of the entire opening as well as the thickness of the old pane. To determine the exact dimensions of the new pane, subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass. You can take these measurements to a hardware or home improvement shop and have the glass cut for you.

Now, it’s time to bed the new window replacement 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.
