Remove any broken glass pieces remaining. This is best done using pliers, but a flathead screwdriver may be used in a pinch. Utilize a wood chisel or putty knife to get rid of any remaining old putty around the frame and window sash. Be careful and slow, taking care not to break the current window sash. This should be done on a ladder, not on the ground. Also, have someone on the ground to keep it in place.

Once you have removed all the old putty, it is time to prepare the window frame to accommodate the new pane. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of the width and height. Take these measurements to the nearest hardware store or home center and get a piece of stock glass cut to size. Alternately, you can cut the glass yourself, if you have the appropriate tools.

After installing the new glass After installing the glass, apply some caulking around the edge. This will make the glass weatherproof. Then install a glazier's point on the frame's opposite side to secure the pane in the right place. The points shouldn't be so tight that they create friction between the frame and sash, but they should also not be loose.

Before applying the putty to the surface, knead thoroughly until it becomes soft and free from lumps. Cut it into pencil-sized pieces. The first strip should be placed in the corner of the frame, working from one corner to the next to ensure it is even and smooth.

Glazier's Points

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

After the old putty and the glazier's point are gone, thoroughly clean the frame with a utility knife to get rid of any remaining residue. If necessary you can lightly sand the wood along the grooves of the rabbet to smooth out rough areas. If you do sand your wood, ensure you protect it with painter's tape to avoid accidental damage.

Take the dimensions of the frame and write down accurate measurements. Take these measurements to an hardware store or home center and have the new pane cut smaller than the frame's opening. This will ensure a snug fit and leave room for expansion and contraction.

Place the new pane in the frame and push it in using your hands. Then, you can use the point of your chisel or the back end of the putty knife to tap in the glazier's points as illustrated in Figure 11. After you're done, the points should be in line with the top edge of the pane. 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 edges of the glass. This will protect and seal the edges. Allow this to dry and cure completely.

When the glazing compound is dry and the glazing compound is dry, you can install the new window sash. The first step is to coat the wood with a heavy coat of linseed oil. This will keep the new putty from taking up the moisture and deteriorating and cracking with time. Apply the coating using a brush this coat, or the point of the blade. Then, use the chisel that is 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 rabbet grooves. Repeat this process every 10 inches around the perimeter of the frame.

Putty

A baseball thrown or a rock thrown by error, or a fallen tree can result in a cracked or cracked window. The majority of windows can be replaced by installing a new piece. The glass is held into the position with a tiny metal clip, called a glazier’s point and putty. This compound is also referred to as glazing compound. Before installing a replacement pane, first get rid of the old one and clean up the area using a rag and the pull-type paint scraper or the wood chisel. Wear protective glasses and gloves while working. You'll need a heat gun in the event that the window is glued to the frame.

If you plan to reinstall the original sash in the future, take care to remove any molding pieces that are used to secure the old pane. Sand the sash until it is flat and ready for new caulk. After the sash has been put back in place then, you can apply a silicone caulk on the glass. This will ensure that it doesn't be leaking or fade over time.

Remove the glazing points from the rabbets and the grooves in the sash that the glass sits. If they're hard to chisel out, try placing an instrument like a heat gun to soften them first.

Prepare the bed for your new pane after removing the old putty and glazing points. Roll a piece of glazing compound between your hands, and form it to be about 1/2-inch thick. Place it into the rabbets, where the glass will be put. It is crucial that the glass rests against the putty in all places on both sides If you have to, lightly tap the 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 cover the crack prior to pressing it in the sash. In other cases, you'll need to apply putty on the crack to form an airtight seal and keep water out. When the putty dries and the film is oily, wipe it off the glass using an abrasive and allow it to completely dry before painting.

After removing the old pane, clean the frame and the wood. Scrape off any paint and sand down the rabbet grooves where the glazing points were. Sand them down to bare wooden surfaces so you can paint the frames with the same shade. After sanding the wood then apply a layer of flax oil. This will help to extend its life.

Then, take measurements of the dimensions 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 allow for seasonal changes in the glass.

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.
