Remove any broken glass pieces remaining. This is best done using pliers, though using a flathead screwdriver can also work in a pinch. Then, use a wood chisel, or putty knife, to take the remainder of the old putty around the frame and the sash. Be careful and slow, taking care not to damage the old window sash. It is recommended to work on a sturdy ladder rather than the ground, and to place someone on the sash in order to help hold it in place.

Make sure the window frame is ready to accept the new pane once you have removed the old putty. To allow for seasonal expansion or contraction by subtracting 1/8 inch from the measurements of width and height. Bring these measurements to a hardware store or home center and get a piece of stock glass cut to size. You can cut the glass yourself if you possess the right tools.

After installing the new glass Apply caulking around the edge. This will make the glass weatherproof. Then, place a glazier's tip on each side of the frame to secure the pane in its place. The points should not be tight enough to cause friction between the frame and the sash However, they should not be loose.

Before putting the putty on, work it in a gentle manner until it's soft and free of lumps. Then, roll it into pencil-size strips. Apply the first strip to the frame's corner. Work from one corner to another and ensure that it is even and smooth.

Glazier's Points

The glazier's points are small triangular pieces of metal that help secure the glass to the frame without causing any damage to the fragile surface. It's easy to learn how to use this nefarious tool, and you'll save money on the cost of an expert installation.

After the old putty and the glazier's point are gone, thoroughly clean the frame with a utility knife to eliminate any remaining traces. Lightly sand the frame 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.

Measure the empty frame's dimensions and note down precise measurements. Bring these measurements to an hardware store or home center, and have the new pane cut smaller than the frame's opening. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Place the new pane into the frame and push it in with your hands. Utilize the chisel's point, or the back 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 the pane and the shoulders should be just below that lip.

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

Install the new window sash once the glazing compound has dried. The first step is to coat the wood with an even layer of linseed. This will stop the new putty drying out or cracking when it absorbs moisture. Apply the coating using a brush this coat, or the tip of the blade. Then use the chisel on the back of the putty tool or the back of the handle to gently smash the new sash or glazier's point into the grooves of the rabbet. Repeat this process at intervals of 10 inches all around the frame.

Putty

A baseball that is thrown or a rock that is errant or falling branch could cause a window to crack or break. Most windows can be replaced easily by simply putting in a fresh piece. The glass is held in the position with a tiny metal clip, referred to as a glazier’s point and putty. This compound is also known as glazing compound. Before installing a replacement pane, first remove the old one and clean the area using an abrasive and an abrasive scraper that is a pull type or an abrasive wood chisel. Wear safety glasses and gloves while working. If the window is secured to the frame, you'll have to use a heat gun to soften the adhesive prior to cutting it loose.

If you are planning to replace your original sash, you must remove the molding that holds the old pane. Then sand the sash to ensure it's level and ready to be re-caulked. After the sash has been installed then, you can apply a silicone caulk over the glass. This will ensure that it won't leak over time or discolor.

Remove the glazing points in the rabbets. These are the grooves in the sash where the glass is. If they're hard to chisel, use an instrument like a heat gun over them to allow them to soften before. If you're using a heat gun, be cautious not to scratch the railings or sash by placing the tool too close.

Once the old points of glazing and putty have been removed make a bed for the new pane. Roll a piece of glazing compound between your hands, shaping it into a 1/2-inch thick. Place it into the rabbets where the glass will be put. It's important that the glass is positioned against the putty on both sides If you have to, lightly tap the glass into the rabbet using your thumb.

If the new pane has a crack you can fill it with a solvent-based glass glue or silicone caulk prior to pressing it into the sash. If the crack isn't sealed, you'll require putty to keep water from getting in. After the putty has dried clean the oily film off of the glass and let it dry completely before painting. If you paint before the putty is completely dry, it won't form a solid seal and could leak or discolor over time.

They are placed beneath a layer of glazing putty, which transforms into a solid moulded wedge that holds the window firmly in place and hides the window's points.

After you have the old pane taken away Clean up the frame and wood. Scrape away any paint and sand down the rabbet grooves where the glazing points used to be. They should be sanded 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 that is not sanded down to help extend its lifespan.

Next, measure the width of the window opening. You will need to measure the vertical and horizontal dimensions of the entire opening, as well as the thickness. Subtract 1/8 inch from each measurement to ensure that you get a precise size for the new pane. This will allow for seasonal changes in the glass.

When the putty dries, replace Window pane it can be painted with the same color as the frame to prevent water and air from leaking into the frame and causing fogging.
