The procedure of replacing the window pane is easy and can be accomplished by homeowners with basic hand tools. You will also require a upvc replacement window handles window pane, glazier's tips pliers, and latex glazing putty. If necessary you can use a heatgun to warm the old putty. Wear safety glasses and gloves prior to beginning. Working with broken glass can cause serious injuries.

Begin by removing any broken pieces of glass. It is recommended to use pliers however, a flathead may work equally. After that, use a wood chisel or replace Window pane putty knife to remove the rest of the old putty from around the frame and the sash. Take your time and work slowly making sure not to break the existing window sash. It is best to work using a sturdy ladder rather than the ground and to place someone on the sash to help hold it in place.

Make sure the window frame is ready to receive 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. Bring these measurements to the nearest 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 appropriate tools.

After installing the new pane after installing the new pane, put a tiny amount of caulking around the edges to ensure it is weatherproof. Then, you can install a glazier's pointing on the frame's opposite side to secure the pane into place. The points should not be so tight that they cause friction between the frame and sash, but they should also not be loose.

Before applying the putty, make sure to knead it until it is smooth and free of lumps. Make it into pencil-sized strips. Apply the first strip to the frame's corner. Work from one corner to the next to ensure it's even and smooth.

Glazier's Points

The glazier's points are tiny triangular pieces of steel that help secure the glass to the frame without causing any damage to the fragile surface. Understanding how to use these tiny helpers is simple and can save you money on a professional installation or the cost of new glass.

After the old putty as well as the glazier's point are gone Clean the frame thoroughly with a knife to get rid of any remaining traces. Lightly sand the wood in the rabbet grooves if needed to smooth out rough areas. If you do sand the wood, ensure you protect it with painter's tape to avoid accidental damage.

Take the dimensions of the frame and record precise measurements. Bring these measurements to a hardware store or a home center and have the new pane cut smaller than the frame's opening. This will ensure a secure fit and will allow room for expansion and contraction.

Place the new pane into the frame and press it down with your hands. Use the chisel's point or the edge of the putty blade to tap in the glazier's points, as illustrated in Figure 11. When you're done taping, they should be flush with the top edge of the pane, and the raised shoulders of the points should be below the rabbet's lip. groove.

Apply a thin layer of glazing compound to the rabbet grooves and edges of the 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, coat the wood with a thick layer of linseed. This will stop the new putty from taking up the moisture and deteriorating and cracking over 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 putty tool or the back of the handle to gently hit the new sash, or glazier's point into grooves of the rabbet. Repeat this process in intervals of 10 inches around the frame.

Putty

A baseball thrown, a rock thrown in error or a branch falling can result in a cracked or cracked window pane. Most windows can be replaced easily by simply putting in a fresh piece. The glass is held in position by a small metal clip, referred to as a glazier’s point and putty. This compound is also called glazing compound. Before you install a new pane, first remove the old one and clean the area using a rag and an abrasive scraper that is a pull type or an abrasive wood chisel. Wear protective glasses and gloves while working. You'll need a heat gun in the event that the window is glued to the frame.

If you plan to reinstall the original sash in the future, take care to remove the molding pieces that hold the old pane in place. Then sand the sash to ensure it's level and ready to be re-caulked. After the sash has been put back in place then, you can apply a silicone caulk to the glass. This will ensure that it won't get soiled or discolor over time.

Take the glazing points out of the rabbets, the grooves in the sash where the glass is. If they're hard to chisel, hold an instrument such as a heatgun over them to soften first. When using a heating tool, be careful to not damage the sash's railings and sash.

After the old glazing points and putty have been removed prepare a bed for the new pane. Roll a rope of glazing compound between your fingers, and make it around 1/2 inch thick. Then, press it into the rabbets where the glass will sit. It is crucial that the glass sits on the putty on each side If you have to, lightly tap the glass into the rabbet using your thumb.

If the new pane is damaged, you can use a silicone caulk or a glass glue that is based on solvents to cover the crack prior to pressing it in 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 then clean the oily film off the glass using a rag and allow it to completely dry before painting. Paint after the putty has completely dried. It won't form a good seal and may be leaking or discoloring over time.

Paint

You may be concerned about replacing a broken piece of glass. However, replacing one glass pane does not have to break the bank when you do it yourself. In fact windows with double panes can be replaced at a fraction of the cost of a professional.

If you are working with a large glass window first, ensure that it is securely attached to the frame. This task is relatively easy and fast with the proper tools and techniques.

When you are ready to start with the removal of the window pane. Pry out the metal glazing points that are attached to it. These are tiny triangles of metal that function as "nails" to hold the window in place. They are placed under a glaze putty or bead that hardens to an unbreakable wedge which holds the wood frame in place and conceals the edges.

After you have removed the old pane removed Clean up the frame and wood. Scrape off any paint that has been used, and sand the rabbet grooves where the glazing points were. Sand them down to bare wooden surfaces, allowing you to paint the frames with the same color. After sanding the wood then apply a layer of flax oil. This will help to prolong the life of the frame.

Then, you need to measure the width of the window opening. You will need to take horizontal and vertical measurements of the entire opening, as well as the thickness of the old pane. 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. Take these measurements to the hardware or home improvement store and ask them to cut you 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.
