It is a good idea to do this on a stable ladder rather than the ground and place someone on the sash to help keep it in place.

Once you have removed all the old putty, prepare the window frame to fit the new pane. To allow for seasonal expansion or contraction, subtract 1/8 inch each from the measurements of the width and height. Bring these measurements to an 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 have the right tools.

After installing the new pane, run a small bead of caulking around the edges to ensure it is weatherproof. Install a glazier’s point on both sides of the frame. This will help secure the pane. The points shouldn't be so tight that they cause friction between the sash and the frame but they should not be too loose.

Before applying the putty, make sure to knead it until it is soft and free of lumps. Then, roll it into pencil-size strips. 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 the tiny triangular pieces of steel that allow glass to be secured into frames for windows without scratching or damaging the delicate surface.

Take measurements of the empty frame and write down accurate measurements. These measurements can be brought to the hardware or home center store and the new pane will be cut a bit smaller. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Place the new pane into the frame and push firmly using your hands. Make use of the chisel's point or the edge of the putty blade to smudge the glaziers' points as shown in Figure 11. When you're done, they should be in line with the top edge of the pane and the shoulders that are raised of the points should be just below the rabbet's lip. groove.

Apply a small amount 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 once the glazing compound has dried. The first step is to coat the wood with a thick layer of linseed. This will prevent the new putty from sucking in the moisture and deteriorating and cracking with time. Use a brush to apply this coat, or even the tip of the blade. Then, use the chisel on the back of the tool or the back of the putty handle to gently hit the new sash, or glazier's point into the rabbet grooves.

Putty

A baseball thrown at you, an errant rock or falling branch could cause a window pane to break or crack. The majority of windows can be repaired easily by putting in a new piece. The glass is held in place by small clips made of metal called a glazier's point, and putty, often called glazing compound. Before installing a new pane, first get rid of the old one and clean the area using an abrasive and the pull-type paint scraper or an abrasive wood chisel. Wear gloves and safety glasses while you do this work. If the window is glued to the frame, you'll need to employ a heat gun in order to soften the adhesive prior to taking it off.

If you plan to reinstall the original sash in the future, take care to remove the molding pieces that hold the old pane in place. Then, sand the sash to ensure it's smooth and ready for new caulk. Once the sash is re-installed then, apply a new caulk made of silicone around the glass to ensure it won't leak or discolor Replace Window Pane over time.

Take the glazing points out of the rabbets and the grooves in the sash where the glass sits. If they're difficult to work out, try placing a hand tool like a heat gun to soften them up first. If you're using a heated gun, make sure not to damage the sash or replace Window Pane its railings by using the tool too closely.

After the old glazing points and putty have been removed make a bed for the new pane. Roll a piece of glazing compound between your hands, and form it into a 1/2-inch thick. Press it into the rabbets where the glass will be placed. The glass must rest against the putty on both sides. If necessary, lightly tap your glass into the rabbet with your thumb.

If the new pane has cracked, you can apply a silicone caulk or glass glue that is based on solvents to seal the crack before pressing it in the sash. In other cases, you'll need to putty over the crack to form an impervious seal to keep water out. After the putty is dry and the film is oily, wipe it off the glass using the help of a rag.

These are small metal triangles that act as "nails" to hold the window within the frame. They are buried beneath a layer of glazing putty, which transforms into a solid molded wedge which holds the window in place and hides the edges.

After removing the old pane, clean the frame and wood. Scrape off any paint that has been used and sand down the rabbet grooves in which the glazing points were. Sand them to bare wooden surfaces, allowing you to paint the frames the same color. After the sanding process, apply a coat of flax oil to the bare wood to extend the life of the frame.

Next, measure the size of the upvc window handle replacement's opening. You'll need to determine the vertical and horizontal dimensions of the entire opening as well as the thickness. To get the exact size of the new pane, subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass.

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.

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.
