How to Replace Window Panes

A damaged or cracked window is an inconvenience. It can also be a chance to upgrade your glass to energy efficient or insulated windows and enjoy benefits such as greater comfort, a higher potential for resales, and less bills.

It’s a task you can take on yourself for less than the cost of hiring an expert. You’ll need only the appropriate tools and a few minutes of your time.


Replace your old single-paned windows with tempered or insulate glass to improve energy efficiency, cut down on noise, and maintain the historic integrity of your home’s older. The replacement windows prices of the window pane is easy and can be accomplished by anyone with basic hand tools. You will also need an additional window pane, glazier’s suggestions, pliers, and latex glazing putty. If you need to you may use a heatgun to warm the old putty. Wear safety goggles and gloves prior to beginning. Working with broken glass can cause serious injuries.

Take away any broken glass pieces that remain. It is recommended to use pliers, but a flathead can be useful as well. After that, use a wood chisel or putty knife remove the remaining old putty around the frame and sash. Be careful not to scratch the window sash. Work slowly and [Redirect-302] carefully. It is a good idea to work on a sturdy ladder rather than the ground and to have someone stand below the sash to help hold it in place.

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

After installing the new glass After installing the glass, apply caulking on the edges. This will make the glass weatherproof. Then, you can install a glazier’s pointing on the frame’s opposite side to hold the pane in the right place. The points shouldn’t be too tight that they cause friction between the frame and sash however they shouldn’t be too loose.

Before applying the putty knead it thoroughly until it is soft and free of lumps. Cut it into pencil-sized pieces. Place the first strip to the corner of the frame, moving from one corner to another so that it is smooth and even.

Glazier’s Points

The glazier’s points are the small triangular pieces that help secure glass into a window frame without scratching or damaging the delicate surface. It’s easy to understand how to use this nefarious tool, and you’ll save money on the cost of an installation by a professional.

After the old putty and the glazier’s point are gone and the frame is thoroughly cleaned using a utility knife to remove any remaining residue. Lightly sand the wood into the rabbet grooves, if necessary, to smooth out rough areas. If you sand wood cover it with painter’s tape to protect it from damage caused by accidental sanding.

Write down the exact dimensions of the frame. These measurements can be brought to the hardware or home center store and the new pane will be cut a bit smaller. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Place the new pane into the frame and press it into the frame by using your hands. Then, you can use the point of your chisel, or the back end of the putty knife to tap in the glazier’s points, as illustrated in Figure 11. The glazier’s points should be flush against the top edge of your pane, and the raised shoulders should be just beneath that lip.

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.

Install the new window sash when the glazing compound has dried. First, you need to coat the wood with a thick layer of linseed. This will prevent the new putty from soaking up moisture and deteriorating and cracking over time. Apply the coat using a brush or the edge of your putty knife, and then employ the chisel or back end of the knife to gently hammer the new sash and glazier’s points into the grooves of the rabbet. Repeat this process in intervals of 10 inches all around the frame.


A baseball thrown or a rock thrown in error, [Redirect-Java] or a tree falling can result in a cracked or cracked window pane. Luckily, most windows can be easily replaced by simply placing a new piece of glass in its place. The glass is held in the position with a tiny metal clip, called a glazier’s point and putty. This compound is also called glazing compound. Before installing a new pane, first remove the old one and clean the area using an abrasive and an abrasive scraper that is a pull type or the wood chisel. Wear safety glasses and gloves while working. You’ll need a heat gun if the window is glued into the frame.

If you are planning to install the original sash, take off the mold that holds the old pane. Sand the sash until it’s flat and ready to receive new caulk. Once the sash is re-installed, apply a new silicone caulk to the glass to ensure it won’t leak or discolor as time passes.

Remove the glazing points from the rabbets, the grooves in the sash that the glass is. If they’re hard to chisel out, you can try holding an instrument like a heat gun over them to soften them before you do. If you’re using a heat gun, be careful not to cause damage to the railings of the sash or the sash itself by placing the tool too close.

Make a bed for your new pane by removing the old glaze points and putty. Roll a rope of glazing compound between your hands, and form it to be around 1/2-inch thick. Press it into the rabbets where the glass will be placed. It’s important that the glass is positioned against the putty on each side So if you have to tap it, gently press the glass into the rabbet using your thumb.

If the new pane has a crack you can fill it with a solvent-based glass glue or silicone caulk prior to pressing it into the sash. Otherwise, you’ll need to apply putty over the crack to create a tight seal and keep water out. After the putty has dried remove the oily film from the glass and let it dry completely before painting. Paint before the putty has dried completely. It won’t make a strong seal and may leak or discolor with time.


If you’ve had a broken window pane, you might be worried about the expense of replacing it. It’s true that replacing a single pane glass doesn’t need to be expensive if you do it on your own. In fact even windows with double panes can be replaced at a fraction of the cost of an expert.

First, if you’re working on a large window, ensure that it is securely attached to the frame. By using the correct tools and techniques to complete this task easily and quick.

When you’re ready to start taking off the old window pane by prying out the glazing points made of metal that are connected to it. These are essentially small metal triangles which function as “nails” that hold the window in place within the frame of wood. They are buried beneath a bead or glazing glue that sets to form solid wedge which holds the wood frame in place and conceals the edges.

After you have removed the old pane taken away, clean up the surrounding frame and wood. Scrape away any old paint and sand down the rabbet grooves where the glazing points were. Sand them down to clean wooden surfaces so you can paint the frames the same color. After sanding the wood, apply a layer of flax oil. This will help extend its life.

The next step is to determine the width of the window’s opening. You’ll need to determine the horizontal and vertical dimensions of the entire opening as well as the thickness. To get 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 during seasonal change. You can take these measurements to a hardware or home improvement shop and get 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.
