The replacement of the window pane is easy and can be completed by most homeowners who possess basic hand tools. In addition to a replacement pane, the following components are needed: latex glazing putty; glazier's points; pliers; and an electric heater to warm the old putty if required. Before beginning, wear protective gloves and goggles since working with broken glass could cause injuries.

Begin by removing any broken pieces of glass. This can be done with a pair of pliers, though using flathead screwdrivers can be used in a pinch. Then, use a wooden chisel or putty knife to remove the rest of the old putty around the frame and sash. Take your time and work slowly making sure not to break the existing window sash. It is best to do this on a sturdy ladder rather than the ground, and to have someone stand below the sash in order to help hold it in place.

Prepare the window frame to accept the new pane once you have removed the old putty. Find the width and the height of the opening for the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to the nearest hardware store or home center, and find a piece glass cut to size. Alternately, you can cut the glass yourself, if you have the right tools.

After putting in the new glass, apply caulking to the edge. This will make the glass weatherproof. Install a glazier's point on both sides of the frame. This will ensure the pane. The points should not be too tight that they create friction between the frame and the sash, but they should also not be loose.

Before applying the putty to the surface, gently knead it until it is smooth and free of lumps. Then, roll it into pencil-size strips. Apply the first strip in the corner of the frame, moving from one corner to the next to ensure it is even and smooth.

Glazier's Points

The glazier's points are tiny triangular pieces of steel which help to secure the glass into the window frame without causing damage to the delicate surface. Learning how to use these hidden tiny helpers is simple and could save you money on a professional installation or the cost of new glass.

Once the old putty and replace window pane glazier's points are removed Clean the frame thoroughly using a utility knife to get rid of any remaining residue. If needed, lightly sand the wood along the rabbet grooves to smooth out rough spots. If you do sand the wood, be sure to protect it with painter's tape to avoid accidental damage.

Write down the exact dimensions of the frame. Take these measurements to an hardware store or 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.

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

Apply a small amount of glazing compound over the edges of the new glass and in the rabbet grooves to seal and protect them. Allow it to dry and cure completely.

When the glazing compound is dry, you're ready to install the new window seal replacement sash. The first step is to coat the wood with an even layer of linseed. This will prevent the newly-created putty from drying out or cracking as it absorbs moisture. Apply the coat using a brush or the tip of your knife, then use the chisel, or the back end of the putty knife to gently hammer the new sash and glazier's point into the grooves of the rabbet. Repeat this process every 10 inches around the frame's perimeter.

Putty

A baseball thrown or a rock thrown by error, or a tree falling can cause a broken or cracked window. Luckily, most windows can be repaired by simply placing a new piece in the right place. The glass is held in place by a small metal clip, referred to as the glazier's point, and putty. This compound is also called glazing compound. Before installing a replacement pane, first remove the old one and clean up the area with the help of a rag, an abrasive scraper that is a pull type or the wood chisel. Wear gloves and safety glasses while you do this work. You'll require a heat gun when the window is fixed to the frame.

Take out the glazing points in the rabbets. These are the grooves in the sash, which is where the glass is. If they are hard to chisel, hold the hand tool, such as a heatgun over them to soften first. If you're using a heat gun, be careful not to scratch the railings or sash by holding the tool too tightly.

Create a bed for your new pane after you have removed the old glaze and putty. Roll a rope of glazing compound between your fingers and then make it about 1/2 inch thick. Then, press it into the rabbets in which the glass will be. The glass must rest against the putty on both sides. If needed you want to tap your glass lightly into the rabbet with your thumb.

If the new pane has a crack then you can seal it with a solvent-based glue or silicone caulk before pressing it into the sash.

When you are ready to begin with the removal of the window pane. Take out the metal glazing points attached to it. They are basically tiny metal triangles which function as "nails" that keep the window in place in the wood frame. They are submerged beneath a layer of glazing putty, which hardens into a solid, formed wedge that secures the window in place and conceals the edges.

After you have removed the old pane taken away clean the surrounding frame and wood. Scrape off any paint and sand down the rabbet grooves where the glazing points used to be. Sand them to bare wooden surfaces, allowing you to paint the frames the same shade. After the sanding process, apply a coat of flax oil on the bare wood to help extend its lifespan.

The next step is to measure the dimensions of the window opening. You'll need to take horizontal and vertical measurements of the entire opening, as well as the thickness of the old pane. Subtract 1/8 inch from each measurement to ensure that you get the exact measurement for the new pane. This will also allow for Replace window Pane expansion and contraction of the glass during seasonal change. Take these dimensions to the hardware or home improvement store and ask them to cut you cut the glass for you.

Now, it's time to bed the new window pane.

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.
