Remove any broken glass pieces remaining. This can be done with pliers, but a flathead screwdriver may work in a pinch. Use a wood chisel, or putty knife to get rid of any remaining old putty around the frame and window sash. Work slowly and carefully making sure not to break the existing window sash. This is best done on an elevated ladder, not on the ground. Also, have someone below the sash keep it in place.

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

After installing the new glass Apply some 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 too tight that they cause friction between the frame and sash but they shouldn't be too loose.

Before putting the putty on, make sure to knead it until it is smooth and free of lumps. Then you can roll it into pencil-sized strips. Apply the first strip to the corner of the frame. Work from one corner to another to ensure it's even and smooth.

Glazier's Points

The glazier's points are small triangular pieces that allow glass to be secured into the frame of a window without scratching or damaging the fragile surface. It's simple to learn how to use this nefarious tool, and you'll be able to save money on the cost of a professional installation.

After the old putty as well as glazier's points are removed and the frame is thoroughly cleaned using a utility knife to remove any remaining traces. If needed, lightly sand the wood along grooves of the rabbet to smooth out rough spots. If you do sand your wood, make sure to protect it with painter's tack to avoid accidental damage.

Measure the empty frame's dimensions and record precise measurements. Take these measurements to a hardware store or home center and request that the new pane cut slightly smaller than the frame's opening. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Insert the new pane into the frame and push it in with your hands. Then, use the tip of your chisel, or the back of the putty knife to pierce the glazier's points, as illustrated in Figure 11. The glazier's point should be flush against the top edge of the pane and the raised shoulders should be just below that lip.

Apply a thin bead of glazing compound on the edges of the glass that has been made and into the rabbet grooves to seal and protect them. Let it dry and cure fully.

Install the new window sash when the glazing compound has dried. The first step is to coat the wood with a thick layer of linseed. This will keep the new putty from sucking up the moisture and drying out and cracking with time. Use a brush to apply 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 putty handle to gently smash the new sash or glazier's tip into the rabbet grooves. Repeat this process in intervals of 10 inches all around the frame.

Putty

A baseball thrown at you, an errant rock or a fallen branch can cause a window to crack or break. Most windows can be replaced easily by installing a new piece. The glass is held in place with small clips made of metal called a glazier's point and putty, upvc replacement window handles often called glazing compound. Before installing a replacement pane, first get rid of the old one and clean the area with a rag and a pull-type paint scraper or the wood chisel. Wear safety glasses and gloves while working.

After the sash has been reinstalled then, you can apply a silicone caulk on the glass. This will ensure that it doesn't be leaking or fade over time.

Take out the glazing points in the rabbets. These are the grooves on the sash, which is where the glass is.

If the new pane has a crack you can fill it with a solvent-based glass glue or silicone caulk prior pressing it into the sash. Otherwise, you'll need to apply putty over the crack to create a tight seal and keep water out.

Paint

If you've had a broken window pane, you may be worried about the cost of a new one. It's true that replacing a single pane of glass doesn't have to be expensive if you do it on your own.

Once you're ready to begin, begin by removing the old window by prying out the glazing points made of metal that are attached to it. These are tiny metal triangles that function as "nails", holding the window in the frame. They are buried beneath a bead or glazing putty that hardens to an unbreakable wedge that holds the wood frame securely in place and hides the points.

After removal of the old pane clean the frame and the wood. Scrape off any old paint and sand down the rabbet grooves where the glazing points were. These should be sanded to bare wood, to allow you to paint them the same shade as the rest of the frame. After sanding, apply a coat of flax oil on the bare wood to prolong its life.

Next, measure the size of the window's opening. It is necessary to take vertical and horizontal measurements of the entire opening, and also 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 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.
