Before starting, put on protective gloves and goggles since working with broken glass may cause injuries.

Begin by removing any remaining broken pieces of glass. It is recommended to use pliers for this however a flathead could be used equally. Then, use a wooden chisel or putty knife to remove the rest of the old putty around the frame and sash. Be careful and slow, taking care not to break the existing window sash. It is recommended to work on a stable ladder rather than on the ground, and to have someone standing below the sash in order to help hold 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, subtract 1/8 inch each from the measurements of the width and height. Take these measurements to an hardware store or home center and have a piece of stock glass cut to size. Alternately, you can cut the glass yourself if have the tools you need.

After putting the new pane in place, run a small bead of caulking along the edge to make it weatherproof. Then, you can install a glazier’s pointing on each side of the frame to secure the pane into its place. The points shouldn’t be so tight that they cause friction between the sash and frame but they should not be too loose.

Before applying the putty to the surface, replacement double glazed windows knead thoroughly until it is smooth and free from lumps. Then make it into pencil-sized strips. Apply the first strip to the frame’s corner. Work from one corner to another, making sure it is even and smooth.

Glazier’s Points

The glazier’s points are small triangular pieces of metal that allow glass to be secured into frames for windows without scratching or damaging the fragile surface. It’s easy to understand how to use this nefarious tool, and you’ll save money on the cost of an expert installation.

Once the old putty and glazier’s points are removed and the frame is thoroughly cleaned with a utility knife to remove any remaining residue. If needed you can lightly sand the wood in the rabbet grooves to smooth out rough spots. If you do sand your wood, be sure to protect it by using painter’s tape to prevent accidental damage.

Take measurements of the empty frame and write down accurate measurements. Take these dimensions to an hardware store or home center, and have the new pane cut smaller than the frame’s opening. This will ensure a secure fit and leave room for expansion and contraction.

Insert the new pane into the frame and push firmly with your hands. Then use the point of your chisel, or the back end of the putty knife to pierce the glazier’s facets, as illustrated in Figure 11. The glazier’s points should sit in line with the top edge of the pane and the raised shoulders should be just beneath that lip.

Apply a small amount of glazing compound over the edges of the glass that has been made and into the rabbet grooves, to seal and protect them. Allow this to dry and cure completely.

After the glazing compound dries and the glazing compound is dry, you can install the new window sash. First, saturate the wood with a thick coat of Linseed oil. This will prevent the new putty drying out or cracking due to the moisture it absorbs. Use a brush to apply this coat, or the point of the putty blade. Then use the chisel on the back of the tool or the back of the handle to gently hammer the new sash or glazier’s point into the grooves of the rabbet. Repeat this process in intervals of 10 inches all around the frame.


A baseball hit or a rock thrown in error, or a tree falling can result in a cracked or cracked window pane. Luckily, most windows can be replaced by simply putting a new piece of glass in its the proper place. The glass is held into position by a small metal clip, referred to as a glazier’s point and putty. This compound is also referred to as glazing compound. Before installing a new pane, first take out the old one and clean the area with an abrasive and an abrasive scraper that is a pull type or an abrasive wood chisel. Wear safety glasses and gloves when you work. If the window is secured to the frame, you’ll have to use a heat gun to soften the adhesive before taking it off.

If you are planning to install the original sash, take off the molding that holds the old pane. Sand the sash until it is flat and ready to receive new caulk. Once the sash is installed then, apply a new silicone caulk to the glass to ensure that it doesn’t swell or fade as time passes.

Take the glazing points out of the rabbets and the grooves in the sash where the glass sits. If they’re difficult to chisel, hold a hand tool like a heat gun over them for a few minutes to soften them. When using a heat tool, make sure to not damage the sash and its railings.

Once the old glaze points and putty have been removed prepare a bed for the new pane. Roll a rope with glazing compound between your fingers and make it about 1/2 inch thick. Then, you can press it into the rabbets where the glass will sit.

If the new pane has cracked, you can use a silicone caulk or a glass glue made from solvents to seal the crack before pressing it into the sash. Otherwise, you’ll need to apply putty over the crack to form an airtight seal and keep water out.

You may be concerned about replacing a broken piece of glass. In reality, replacing a single pane of glass doesn’t need to be costly even if you do it your own. In fact even windows with double panes can be replaced for a fraction of the cost of an expert.

First, if you are working on a large-sized window, make sure that it is securely fastened to the frame. With the right tools and techniques you can accomplish this task fairly easily and quick.

When you are ready to start, remove the old window pane. Take out the metal glazing points that are attached to it. These are tiny triangles of metal which act as “nails” that hold the window within the frame. They are placed under a bead or glazing putty that sets to form solid wedge that holds the frame securely in place and hides the points.

After removing the old pane, clean the frame and the wood. Scrape off any paint that has been used and sand the rabbet grooves in which the glazing points were. Sand them to bare wood surfaces, so that you can paint the frames with the same shade. After sanding, apply a coat of flax oil on the wood that is not sanded down to help extend its lifespan.

Then, you need to measure the size of the window’s opening. You’ll need to determine the horizontal and vertical dimensions of the entire opening, as well as the thickness. Subtract 1/8 inch from each measurement to ensure you get a precise size for the new pane. This will also allow for expansion and contraction of the glass during seasonal change. You can bring 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.
