How to Replace Window Panes

A damaged or cracked window is an issue. This can be an opportunity to upgrade your windows to energy efficient or insulated ones and enjoy benefits such as improved comfort, increased resale value and lower utility costs.

This is a project you could tackle yourself at a fraction of the cost of hiring an expert. You'll need only the proper tools and a few minutes of your time.

Glass

Replace your single-paned windows using tempered or insulation glass to improve energy efficiency, reduce noise, and preserve the historic integrity of your home's older. A majority of homeowners with hand tools can replace a window pane. In addition to a replacement pane, the following items are required such as latex glazing putty; pliers, glazier's points and an electric heater to warm the old putty, if necessary. Wear safety goggles and gloves prior to beginning. Working with broken glass could result in serious injuries.

Begin by removing any remaining broken pieces of glass. This can be done with pliers, however, a flathead screwdriver may work in a pinch. Use a wood chisel, or putty knife to get rid of any old putty that remains around the frame and the window sash. Be careful not to break the window sash. Be careful and slow. This can be done best on an elevated ladder, not on the ground. Also, have someone below the sash ensure it is held steady.

Make sure that the window frame is ready to accommodate the new pane once you have removed the old glue. Measure the width and height of the opening for the sash and subtract 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Bring these measurements to the nearest hardware store or home center, and have a piece of stock glass cut to size. You can also cut the glass yourself if have the right tools.

After installing the new glass Apply a small amount of caulking on the edges. This will make the glass weatherproof. Then, place a glazier's tip on the frame's opposite side to secure the pane in its place. The points shouldn't be so tight that they cause friction between the frame and sash however they should not be loose.

Before applying the putty knead it thoroughly until it is smooth and free of lumps. Then, roll it into pencil-size strips. The first strip should be glued to the frame's corner. Work from corner to corner, making sure it is even and smooth.

Glazier's Points

The glazier's points are tiny triangular metal pieces that allow glass to be secured into the window frame without causing any damage to the fragile surface. It's easy to learn how to use this hidden tool, and you'll save money on the expense of a professional installation.

After the old putty and the glazier's points have been removed, thoroughly clean the frame using a utility knife to get rid of any remaining traces. Lightly sand the wood in the rabbet grooves, if necessary, to smooth out rough areas. If you do sand the wood, be sure to protect it with painter's tape to avoid accidental damage.

Write down the dimensions of the frame. These measurements can be brought to the hardware or home center store, and the new frame will be cut a bit smaller. This will ensure a snug fit and leave room for expansion and contraction.

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

Apply a thin layer of glazing compound on the edges of the glass that has been made and into the rabbet grooves, to seal and protect them. Let it dry completely and cure.

When the glazing compound is dry and the glazing compound is dry, you can install the new window sash. First, saturate the wood with a heavy coat of Linseed oil. This will prevent the new putty from drying out and cracking as it absorbs moisture. Apply this coat with a brush or the tip of your putty knife, and then use the chisel, or the back end from the putty knife to gently hammer in the new sash and glazier's point into the rabbet grooves. Repeat this process at intervals of 10 inches around the frame.

Putty

A baseball hit, a rock thrown in error, or a fallen tree could result in a broken or cracked window pane. Fortunately, the majority of windows can be repaired by simply putting a new piece in place. The glass is held into place by a small metal clip, called a glazier’s point and putty. This compound is also referred to as glazing compound. Before you install a new pane, first remove the old one and clean up the area with the help of a rag, the pull-type paint scraper or a wood chisel. Wear gloves and safety glasses while you do this work. If the window is glued to the frame, you'll need to make use of a heat gun to soften the adhesive prior to taking it off.

If you are planning to install your original sash, remove the mold that holds the old pane. Sand the sash until it's flat and ready for new caulk. Once the sash is reinstalled then, you can apply a silicone caulk over the glass. This will ensure that it doesn't leak over time or discolor.

Take out the glazing points in the rabbets. These are the grooves in the sash where the glass is located. If they're difficult to cut out, try placing an instrument like a heat gun over them to soften them before you do. When using a heating tool, be sure to not damage the sash or its railings.

Prepare a bed for your new pane after removing the old glaze points and putty. Roll a piece of glazing compound between your hands, shaping it to be around 1/2-inch thick. Press it into the rabbets where the glass will be placed. The glass should rest against the putty on both sides. If necessary you want to tap your glass lightly into the rabbet with your thumb.

If the new pane has cracked, you can apply a silicone caulk or a glass glue that is based on solvents to fill in the crack prior to pressing it into the sash. If the crack is not sealed, you will need to apply putty to keep water from getting in. After the putty has dried then clean the oily film off the glass using an abrasive and allow it to completely dry before painting. Paint after the putty has dried completely. It won't form a good seal and may leak or discolor with time.

Paint

If you've had a broken window and door replacement pane, you may be worried about the expense of a new one. The truth is, replacing a single pane glass doesn't need to be expensive if you do it on your own. In fact, even a double glazing windows replacement-pane window can be replaced at less than the cost of an expert.

If you are working on a large window, make sure it is securely fixed to the frame. Using the proper tools and techniques you can complete this task easily and fast.

When you are ready to begin, remove the old window pane. Pry out the glazing points made of metal that are attached to it. These are tiny triangles of metal which act as "nails" to hold the window in the frame. They are buried beneath a glaze putty or bead which hardens into a solid wedge which holds the wood frame in place and hides the points.

After you have removed the old pane taken away clean the surrounding frame and wood. Scrape off any paint that has been used, and sand the rabbet grooves in which the glazing points were. Sand them to bare wood surfaces, so that you can paint the frames the same shade. After sanding, apply a coat of flax oil on the wood that is not sanded down to extend the life of the frame.

The next step is to measure the dimensions of the window opening. It is necessary to take vertical and horizontal measurements of the entire opening, and also the thickness of the old pane. Subtract 1/8 inch from each measurement to ensure that you have the exact size 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.
