Most homeowners with basic hand tools can repair a window pane. Alongside a replacement pane, the following tools are required such as latex glazing putty; pliers, glazier's points and a heat gun for warming the old putty, if necessary. Before beginning, wear protective gloves and goggles since working with broken glass could cause injuries.

Begin by removing any remaining broken pieces of glass. It is best to use pliers however, a flathead may work as well. Utilize a wood chisel or putty knives to remove any old putty that remains around the frame and window sash. Work slowly and carefully making sure not to break the existing window sash. It is recommended to do this using a sturdy ladder rather than the ground, and to have someone standing below the sash to help keep it steady.

Prepare the window frame to accommodate the new pane after you have removed the old putty. Take measurements of the width and height of the sash opening, subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to a hardware or home center store to get cut a piece of glass that is in stock to the correct size. Alternatively, you can cut the glass yourself if have the right tools.

After putting in the new pane, run a small bead of caulking around the edges to seal it against weather. Install a glazier’s point on both sides of the frame. This will secure the pane. The points shouldn't be tight enough to create friction between the frame and sash However, they should not be loose.

Before applying the putty work it in a gentle manner until it is soft and free of lumps. Roll it into pencil-sized strips. Place the first strip in the corner of the frame, working from one corner to the other so that it is smooth and even.

Glazier's Points

The glazier's points are small triangular metal pieces that allow glass to be secured into the window frame without causing damage to the delicate surface. Knowing how to use these hidden tiny pieces of help is simple and could save you money on a professional installation or the cost of new glass.

After the old putty and the glazier's point are gone Clean the frame thoroughly with a utility knife to remove any remaining residue. Lightly sand the wood in the rabbet grooves to smooth out rough areas. If you decide to sand wood, protect it with painter’s tape to prevent accidental damage.

Measure the empty frame's dimensions and record precise measurements. Bring these measurements to a hardware store or a home center and request that the new pane cut slightly smaller than the frame's opening. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Place the new pane into the frame and push it in with your hands. Utilize the point of the chisel or the back of the putty knife to smudge the glazier's points, as shown in Figure 11. When you're done, they should be level with the top edge of the pane and the shoulders that are raised of the points should be just below the lip of the rabbet groove.

Apply a thin layer glazing compound on the rabbet grooves as well as the edges of new glass. This will protect and seal the edges. Allow it to dry completely and cure.

Once the glazing compound has dried, you're ready to install the new window sash. First, saturate the wood with a thick coat of Linseed oil. This will stop the new putty from taking in the moisture and deteriorating and cracking with time. Use a brush to apply this coat, or the tip of the blade. Then use the chisel that is 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 process in intervals of 10 inches around the frame.

Putty

A baseball thrown at you or an unintentional rock, or a falling branch can cause a window to crack or break. Luckily, most windows can be replaced by simply putting a brand new piece of glass in its place. The glass is held into place by a small metal clip, referred to as a glazier's point and putty. This compound is also known as glazing compound. Before you install a new pane, first remove the old one and clean the area with a rag and a pull-type paint scraper or the wood chisel. Wear gloves and safety glasses while doing this work. You'll need a heat gun if the window is glued to the frame.

If you're planning to install your original sash, you must remove the molding that supports the old pane. Then you can sand the sash down to make sure it's flat and ready to be re-caulked. After the sash has been installed it is possible to apply a silicone caulk to 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 sits. If they're hard to chisel, hold the hand tool, such as a heatgun over them to soften first. If you're using a heating gun, be cautious not to cause damage to the railings of the sash or the sash itself by holding the tool too closely.

Prepare the bed for your new pane after removing the old glaze points and putty. Roll a rope of glazing compound between your hands, Double Glazed Windows Replacement and form it to be around 1/2-inch thick. Place it into the rabbets where the glass will be put. It is essential that the glass sits on the putty in all places on both sides If you have to tap it, gently press the glass into the rabbet using your thumb.

If the new pane has damaged, you can use a silicone caulk or a glass glue made from solvents to seal the crack prior to pressing it into the sash. If the crack is not sealed, you'll need to use putty to keep water from getting in. After the putty has dried remove the oily film from the glass and let it dry completely before you paint. If you paint before the putty has completely dry, it won't form an effective seal and could be leaking or discoloring in time.

Paint

If you've had a broken window pane, you might be concerned about the expense of a new one. But the truth is that replacing a single glass pane doesn't have to break the bank If you can do it yourself.

If you're working with a large glass window first ensure it is securely attached to the frame. This job can be made relatively simple and quick with the appropriate tools and techniques.

When you are ready to begin, remove the old window pane. Take out the glazing points made of metal that are attached to it. These are tiny triangles of metal that act as "nails" that hold the window in the frame. They are placed under a bead or glazing putty that sets to form an unbreakable wedge which holds the wood frame in place and hides the points.

After taking off 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. They should be sanded to the point of being bare, so that you can paint them the same shade as the rest of the frame. After the sanding process, apply a coat of flax oil to the wood's surface to prolong its life.

Then, take measurements of the dimensions of the window opening. You will need to measure the vertical and horizontal dimensions of the entire opening as well as the thickness. To determine 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 in times of seasonal change. You can take 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.
