It’s a project you can tackle yourself at a fraction of the cost of hiring an expert. You’ll only require the appropriate tools and a few hours of your time.

Glass

If your single pane windows are old damaged, cracked or deteriorating replacing them with modern glass that is tempered or insulated can improve energy efficiency and reduce noise while preserving the historic integrity of older homes. Most homeowners with basic hand tools can repair a window pane. You will also need a replacement double glazed window window pane, glazier’s tips pliers, and latex glaze putty. If you need to, you can use a heatgun to warm the old putty. Before starting, wear protective gloves and goggles since working with broken glass could cause injuries.

Begin by removing any broken pieces of glass. It is recommended to use pliers however, a flathead may be useful equally. 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 scratch the window sash. Work slowly and carefully. This should be done on a ladder, not on the ground. Also, ensure that someone on the ground to hold it steady.

After you’ve removed all the old putty, you can prepare the window frame to accommodate the new pane. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of the width and height. Take these measurements to an hardware store or home center and find a piece glass cut to size. You can also cut the glass by yourself if you have the right tools.

After installing the new glass After installing the glass, apply some caulking to the edge. This will make the glass 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 create friction between the frame and sash, but they also should not be too loose.

Before applying the putty to the surface, Replace Window Pane knead thoroughly until it becomes soft and free from lumps. Make it into pencil-sized strips. Apply the first strip to the corner of the frame, working from one corner to the next so that it is even and smooth.

Glazier’s Points

The glazier’s points are tiny triangular pieces of steel that allow glass to be secured into the replace window pane frame without causing damage to the delicate surface. It’s easy to learn how to use this nefarious tool, and you’ll save money on the expense of a professional installation.

Once the old putty and the glazier’s points have been removed, thoroughly clean the frame with a utility knife to eliminate any remaining traces. If needed, lightly sand the wood in the grooves of the rabbets to smooth out rough areas. If you do sand the wood, make sure to protect it with painter’s tape to avoid accidental damage.

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

Place the new window in the frame and push it in place by using your hands. Use the point of the chisel or the back of the putty blade to tap the glazier’s points as shown in Figure 11. When you’re done taping, they should be flush with the top edge of the pane, and the shoulders of the points should be just below the rabbet’s rim 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. Allow this to dry and cure completely.

Once the glazing compound has dried 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 stop the new putty drying out or cracking due to the moisture it absorbs. Use a brush to apply this coat, or the tip of the putty 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. Repeat this procedure every 10 inches along the perimeter of the frame.

Putty

A baseball thrown, a rock thrown in error or a branch falling can cause a broken or cracked window pane. Most windows can be replaced easily by putting in a new piece. The glass is held into position by a small metal clip, also known as the glazier’s point, and putty. This compound is also called glazing compound. Before installing a new pane, first remove the old one and clean up the area using an abrasive and a pull-type paint scraper or the wood chisel. Wear safety glasses and gloves while you do this work. You’ll need a heating gun if the window is glued to the frame.

If you’re planning to install the original sash, remove any pieces of molding that hold the old pane in place. Sand the sash until it is flat and ready to receive new caulk. After the sash has been put back in place, you can apply a silicone caulk on the glass. This will ensure that it won’t leak over time or discolor.

Take the glazing points out of the rabbets, the grooves in the sash, where the glass is. If they’re difficult to chisel, hold an instrument such as a heatgun over them for a few minutes to soften them. When using a heat tool, be sure to avoid damaging the sash and its railings.

Once the old points of glazing 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. Place it into the rabbets where the glass will be placed. The glass must be positioned against the putty on both sides. If necessary, lightly tap your glass into the rabbet using your thumb.

If the new pane has cracked, you can use a silicone caulk or glass glue that is 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 the water out. Once the putty is dry, wipe the oily film off the glass and allow it to dry completely before you paint. Paint after the putty has dried completely. It will not create a solid seal and could discolor or leak over time.

Paint

If you’ve had a broken window pane, you may be concerned about the expense of replacing it. It’s true that replacing a single pane glass doesn’t need to be expensive if you do it on your own. In fact, even a double-pane window can be replaced for a fraction of the cost of a professional.

If you are working with a large glass window, first make sure it is securely fixed to the frame. This job can be made relatively simple and quick with the right tools and techniques.

When you are ready to begin taking down the old window pane. Remove the glazing points made of metal that are attached to it. These are tiny triangles of metal which act as “nails” that hold the window within the frame. They are submerged beneath a glaze putty or bead that sets to form a solid wedge that holds the wood frame firmly in position and conceals the edges.

After removal of the old pane clean the frame and the wood. Scrape away any old paint and sand down the rabbet grooves where the glazing points were. They should be sanded to the point of being bare, so that you can paint them the same color as the rest the frame. After sanding, apply a layer of flax oil on the wood’s surface to extend the life of the frame.

Then, you need to measure the size of the window 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 that you get the exact measurement 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 store 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.
