Make use of a wood chisel or putty knife to get rid of any remaining old putty around the frame and the window sash. Work slowly and carefully, taking care not to break the current window sash. It is recommended to do this using a sturdy ladder rather than on the ground and place someone on the sash to help keep it in place.

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

After putting the new pane in place after installing the new pane, put a tiny amount of caulking around the edges to ensure it is weatherproof. Then, you can install a glazier's pointing on each side of the frame to hold the pane in the right place. The points shouldn't be tight enough to create friction between the frame and sash, but they should also not be loose.

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

Glazier's Points

The glazier's facets are tiny triangular pieces of steel that help secure glass into a window frame without scratching or damaging the delicate surface. It's easy to understand how to use this hidden tool, and you'll save money on the cost of a professional installation.

Once the old putty and the glazier's point are gone, thoroughly clean the frame using a utility knife to remove any remaining traces. If needed it is necessary to lightly sand the wood in the grooves of the rabbets to smooth out rough spots. If you sand wood, protect it with painter’s tape to prevent accidental damage.

Note down the exact dimensions of the frame. These measurements can be brought to the hardware or home center store, and the new frame will be cut slightly smaller. This will ensure a secure fit and will allow room for expansion and contraction.

Place the new window in the frame and push it in place with your hand. Then, you can use the point of your chisel or back end 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 shoulders should be just below that lip.

Apply a thin layer of glazing compound on the rabbet grooves as well as the edges of the new glass. This will protect and seal the edges. Allow it to dry and cure fully.

Install the new window sash when the glazing compound has dried. First, saturate the wood with a heavy coat of linseed oil. This will stop the new putty from sucking up the moisture and deteriorating and cracking over time. Use a brush to apply this coat, or even the tip of the putty blade. Then, use the chisel that is on the back of the putty tool or the back of the putty handle to gently hit the new sash, or glazier's point into the rabbet grooves. Repeat this procedure every 10 inches around the perimeter of the frame.

Putty

A baseball thrown or a rock thrown in error or a branch falling could result in a broken or cracked window. Fortunately, windows can be replaced by simply placing a new piece of glass in its the right place. The glass is held into place by a small metal clip, referred to as the glazier's point, and putty. This compound is also referred to as glazing compound. Remove the old pane and clean the area with an abrasive, scraper that is a pull type or a wood chisel. Wear gloves and safety glasses when you work. You'll require a heat gun when the window is fixed into the frame.

If you're planning to install the original sash, take off the molding that supports the old pane. Sand the sash until it's flat and ready to receive new caulk. After the sash has been installed, you can apply a silicone caulk to the glass. This will ensure that it won't get soiled 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 out, replace window Pane try holding a hand tool like a heat gun over them to soften them before you do. If you're using a heat gun, make sure not to scratch the railings of the sash or the sash itself by placing the tool too close.

Create a bed for your new pane by removing the old putty and glazing points. Roll a rope of glazing compound between your fingers and make it about 1/2 inch thick. Then, push it into the rabbets in which the glass will sit. The glass must rest against the putty on both sides. If you need to you want to tap your glass lightly into the rabbet using your thumb.

If the new pane is cracked, you can cover 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 need to apply putty to keep water from getting in. After the putty is dry and the film is oily, wipe it off the glass using the help of a rag. Allow it to dry completely prior to painting. Paint after the putty has completely dried. It won't make a strong seal and may be leaking or discoloring over time.

Paint

If you've experienced a broken window pane, then you may be worried about the cost of a new one.

Once you're ready to begin, begin by removing the old window by prying out the glazing points made of metal that are connected to it. These are tiny triangles of metal that act as "nails", holding the window within the frame. They are buried under a bead of glazing putty, which hardens into a solid, moulded wedge that secures the window in place and hides the edges.

After removal of the old pane clean the frame and wood. Scrape off any paint that has been used, and sand the rabbet grooves that the glazing points were. Sand them to bare wooden surfaces, allowing you to paint the frames with the same shade. After sanding the wood, apply a layer of flax oil. This will help to prolong the life of the frame.

Then, you need to measure the size 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. 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.
