In addition to a replacement glass for windows pane, the following items are required such as latex glazing putty; Glazier's points; pliers and an electric heater to warm the old putty, if necessary. Wear safety goggles and gloves prior to starting. Working with broken glass could cause serious injuries.

Take out any broken glass pieces remaining. It is recommended to use pliers for this however a flathead could be useful as well. Then, use a wooden chisel or putty knife remove the rest of the old putty from around the frame and the sash. Be careful not to damage the window sash window replacement. Be careful and slow. It is best to do this on a stable ladder rather than the ground and have someone standing below the sash in order to help hold it steady.

Make sure that the window frame is ready to accept the new pane after you have removed the old glue. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of the width and height. Bring these measurements to the nearest hardware store or home center and find a piece glass cut to size. You can also cut the glass yourself, if you have the appropriate tools.

After installing the new glass After installing the glass, apply caulking on the edges. This will make the glass weatherproof. Install a glazier’s point on both sides of the frame. This will ensure the pane. The points shouldn't be too tight that they create friction between the sash and the frame however they should not be too loose.

Before applying the putty to the surface, you must knead it thoroughly until it is soft and free from lumps. Then you can roll it into pencil-sized strips. Apply the first strip in the corner of the frame, moving from one corner to the next so that it is smooth and even.

Glazier's Points

The glazier's points are tiny triangular pieces of steel that allow glass to be secured into the frame of a window without scratching or damaging the fragile surface. Knowing how to use these tiny pieces of help is simple and can save you money on a professional installation or the cost of buying new glass.

After getting rid of the old putty glazier points as well as any remaining leftovers Clean the frame thoroughly with an utility knife. Lightly sand the frame in the rabbet grooves, if necessary, to smooth rough areas. If you do sand your wood, make sure to protect it by using painter's tape to prevent 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 that the pane fits perfectly and allows for expansion and contraction.

Place the new pane in the frame and push it in with your hands. Then, you can use the point of your chisel or back of the putty knife to tap in the glazier's points, as shown in Figure 11. When you're done, they should be in line with the top edge of the pane. the shoulders of the points should be just below the rabbet's rim groove.

Apply a thin bead 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 from drying out and cracking when it absorbs moisture. Apply the coating using a brush this coat, or even the tip of the blade. Then use the chisel on the back of the putty tool or the back of the putty handle to gently smash the new sash or glazier's point into the rabbet grooves. Repeat this procedure every 10 inches around the frame's perimeter.

Putty

A baseball that is thrown, an errant rock or a falling branch can cause a window to crack or break. Most windows can be replaced by installing 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 you install a new pane, first get rid of the old one and clean up the area with the help of a rag, the pull-type paint scraper or a wood chisel. Wear protective glasses and gloves while working. You'll need a heating gun when the window is fixed into the frame.

If you're planning to replace the original sash, take off the molding that supports the old pane. Sand the sash until it is flat and ready to receive new caulk. Once the sash is put back in place it is possible to apply a silicone caulk on the glass. This will ensure that it doesn't be leaking or fade over time.

Remove the glazing points from the rabbets, or the grooves in the sash where the glass is. If they are hard to cut, place the hand tool, such as a heating gun over them to soften first. When using a heating tool, make sure to avoid damaging the sash or its railings.

Make the bed for your new pane by removing the old putty and glazing points. Roll a rope of glazing compound between your hands, shaping it into a 1/2-inch thick. Place it into the rabbets, Replace window pane where the glass will be put. It is essential that the glass is positioned against the putty on both sides If you have to tap it, gently press the glass into the rabbet using your thumb.

If the new pane is cracked then you can seal it with a solvent-based glass glue or silicone caulk prior to pressing it into the sash. If the crack is not sealed, you will require putty to keep the water out. Once the putty is dry remove the oily film off of the glass and allow it to dry completely before you paint. Paint after the putty is completely dry. It won't form a good seal and could discolor or leak over time.

Paint

You might be worried about replacing a broken piece of glass. It's true that replacing a single piece of glass doesn't need to be costly if you do it on your own. In fact, even a double-pane window can be replaced at less than the cost of a professional.

First, if you are working on a large-sized window, make sure it is securely fixed to the frame. This is relatively easy and fast with the proper tools and techniques.

When you are ready to begin, remove the old window pane. Take out the metal glazing points that are attached to it. These are small metal triangles that act as "nails", holding the window in place. They are placed under a bead of glazing putty that transforms into a solid molded wedge that secures the window in place and hides the window's points.

After taking off the old pane clean the frame and wood. Scrape off any paint that has been used, and sand the rabbet grooves in which the glazing points were. These should be sanded to bare wood to allow you to paint them the same color as the rest the frame. After sanding the wood, apply a layer of flax oil. This will help prolong the life of the frame.

Then, you need to measure the size of the window's opening. It is necessary 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 allow for seasonal changes in the glass. You can take these measurements to a hardware or home improvement shop 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.
