Work slowly and carefully and be careful not to damage the old window sash. This should be done on a ladder, not the ground. Also, have someone below the sash keep it in place.

Once you have removed all the old putty, it is time to prepare the window frame to fit the new pane. Measure the width and height of the opening for the sash and subtract 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to the nearest hardware store or home center, and find a piece glass cut to size. You can cut the glass yourself if you have the appropriate tools.

After installing the new glass After installing the glass, apply some caulking on the edges. This will make the glass weatherproof. Then, you can install a glazier's pointing on each side of the frame to secure the pane into the right place. The points shouldn't be too tight that they create friction between the frame and sash However, they should not be loose.

Before putting the putty on, knead it thoroughly until it's soft and free of lumps. Then you can roll it into pencil-sized strips. The first strip should be placed to the corner of the frame, working from one corner to another so that it is even and smooth.

Glazier's Points

The glazier's points are tiny triangular pieces of steel that help secure glass into frames for windows without scratching or damaging the delicate surface. It's easy to understand how to use this nefarious tool and you can save money on the cost of an installation by a professional.

After getting rid of the old putty glazier points as well as any remaining residue clean the frame thoroughly using a utility knife. If necessary it is necessary to lightly sand the wood along the grooves of the rabbets to smooth rough spots. If you do sand the wood, be sure to protect it with painter's tape to avoid accidental damage.

Write down the dimensions of the frame. These measurements can be brought to an hardware or home centers store, and the new pane will be cut slightly smaller. This will ensure that the pane fits comfortably and allows for expansion and contraction.

Place the new pane in the frame and Replace window pane press it in place using your hand. Use the chisel's point or the edge of the putty blade to smudge the glazier's points, as shown in Figure 11. The glazier's points should be in line with the top edge of your pane, and the shoulders should be just below the lip.

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

Install the new window sash after the glazing compound has dried. First, coat the wood with a heavy coat of Linseed oil. This will stop the new putty from taking in the moisture and drying out and cracking over time. Apply this coat using a brush or the edge of your putty knife, and then employ the chisel or back end of the putty knife to gently hammer in the new sash and glazier's point into the grooves of the rabbet. Repeat this procedure every 10 inches along the frame's perimeter.

Putty

A baseball thrown at you or a rock that is errant or a falling branch can cause a window pane to break or crack. Fortunately, windows can be repaired by simply placing a new piece of glass in its 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 a rag, a scraper that is a pull type or a wood chisel. Wear safety glasses and gloves when working. If the window is attached to the frame, you'll need make use of a heat gun to soften the adhesive prior to prying it free.

After the sash has been re-installed, apply a new caulk made of silicone around the glass to ensure that it doesn't swell or fade in time.

Take the glazing points out of the rabbets, the grooves in the sash, where the glass sits. If they are hard to cut, place the hand tool, like a heat gun over them for a few minutes to soften them. If you're using a heated gun, be cautious not to scratch the sash or its railings by using the tool too close.

Once the old glazing points and putty have been removed, prepare a bed for the new pane. Roll a piece of glazing compound between your hands, forming it to be around 1/2-inch thick. Then, push it into the rabbets, where the glass will be. It is essential that the glass sits on the putty in all places on both sides So if you have to tap it, gently press the glass into the rabbet using your thumb.

If the new pane has a crack you can fill it with a solvent-based glue or silicone caulk prior to pressing it into the sash. If the crack is not sealed, you will need to use putty to keep the water out. After the putty has dried clean the oily film from the glass and allow it to dry completely before painting.

They are buried beneath a layer of glazing putty, which hardens into a solid, formed wedge that holds the window firmly in place and hides the points.

After you have removed the old pane taken away, clean up the surrounding frame and wood. Scrape off any paint and sand down the rabbet grooves, where the glazing points used to be. These should be sanded to the point of being bare, to allow you to paint them the same shade as the rest of the frame. After sanding the wood then apply a layer of flax oil. This will help prolong the life of the frame.

The next step is to determine the size of the window's opening. You will need to measure 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. You can bring these measurements to a hardware store or home improvement shop and have 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.
