Then, use a wood chisel, or putty knife, to take the remainder of the old putty around the frame and sash. Be careful to not damage the window sash. Be careful and slow. It is recommended to work using a sturdy ladder rather than on the ground and place someone on the sash to help hold it steady.

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, subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to a hardware store or home center and get a piece of stock glass cut to size. You can cut the glass yourself if you possess the right tools.

After putting in the new pane After installing the new pane, apply a small amount of caulking along the edge to seal it against weather. Install a glazier's pointing on both sides of the frame. This will ensure the pane. The points should not be tight enough to create friction between the frame and sash however they should not be loose.

Before putting the putty on, work it in a gentle manner until it is smooth and free of lumps. Then, roll it into pencil-size strips. Apply the first strip to the corner of the frame. Work from corner to corner, making sure it is even and smooth.

Glazier's Points

Note down the dimensions of the frame. Take these dimensions to a hardware store or a home center, and have the new pane cut smaller than the frame's opening. This will ensure that the pane fits comfortably and allows for expansion and contraction.

Insert the new pane into the frame and press it down using your hands. Utilize the chisel's point, or the back of the putty knife to tap in the glazier's points as illustrated in Figure 11. The glazier's points should sit flush against the top edge of the pane and the shoulders should be just beneath that lip.

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 Replacement Double Glazed Window cure fully.

Install the new window sash once the glazing compound has dried. First, coat the wood with a thick layer of linseed.

Repeat this process in intervals of 10 inches around the frame.

Putty

A baseball thrown or a rock thrown by error, or a tree falling could result in a broken or cracked window pane. Fortunately, windows can be repaired by simply putting a brand new piece in the proper place. The glass is held into place by a small metal clip, also known 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 pull-type scraper, or a wood chisel. Wear gloves and safety glasses while you do this work. You'll need a heat gun if the window is glued to the frame.

If you are planning to replace the original sash, remove the molding pieces that secure the old pane. Then, sand the sash to make sure it's flat and ready for new caulk. Once the sash is re-installed, apply a new silicone caulk to the glass to ensure that it doesn't swell or fade over time.

Take the glazing points out of the rabbets, the grooves in the sash that the glass is. If they are hard to chisel, hold the hand tool, like a heat gun over them for a few minutes to soften them. When using a heating tool, make sure to not damage the sash's railings and sash.

After the old points of glazing and putty are removed, make a bed for the new pane. Roll a piece of glazing compound between your hands, forming it into a 1/2-inch thick. Then, press it into the rabbets where the glass will sit. The glass must rest against the putty on both sides. If necessary gently tap your glass into the rabbet using your thumb.

If the new pane has cracked, you can apply a silicone caulk or glass glue based on solvents to seal the crack prior to pressing it in the sash. If the crack is not sealed, you will require putty to keep water out. When the putty dries then clean the oily film off the glass using a rag and Replacement double glazed window allow it to dry completely prior to painting.

These are small metal triangles which act as "nails" that hold the window in place. They are buried beneath a layer of glazing putty that transforms into a solid formed wedge that secures the window in place and conceals the window's points.

After removal of the old pane clean the frame and the wood. Scrape off any paint that has been used, and sand the rabbet grooves where the glazing points were placed. Sand them to bare wooden surfaces so you can paint the frames with the same color. After sanding, apply a layer of flax oil on the bare wood to extend the life of the frame.

The next step is to measure the dimensions of the window opening. It is necessary to measure the horizontal and vertical 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 also allow for expansion and contraction of the glass during seasonal changes. You can take these measurements to a hardware store 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.
