How to replace window Pane Window Panes

A damaged window pane could be a nuisance. This could be an opportunity to upgrade to energy-efficient windows or insulated ones and enjoy benefits such as improved comfort, increased resale values and reduced utility bills.

It’s a project you can take on yourself for only a fraction of the cost of hiring an expert. You only need the proper tools and a few hours of your time.


If your single-pane windows are outdated broken, deteriorating or damaged replacing them with modern glass that is tempered or insulated will improve energy efficiency and reduce noise while preserving the original character of older homes. Most homeowners with basic hand tools can replace windows with ease. Alongside a replacement double glazed windows pane, the following components are needed: Replace window pane latex glazing putty; pliers, glazier’s points and an electric heater to warm the old putty if required. Before starting, wear gloves and safety goggles as working with broken glass can cause injuries.

Begin by removing any remaining broken pieces of glass. This is best accomplished with the help of pliers though using a flathead screwdriver can also work in a pinch. Then, use a wooden chisel, or putty knife, to remove the rest of the old putty around the frame and the sash. Be careful not to break the window sash. Work slowly and carefully. This is best done on a ladder, not the ground. Also, you should have someone lower to hold it steady.

Prepare the window frame 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 an hardware store or home center, and find a piece glass cut to size. Alternatively, you can cut the glass yourself if have the appropriate tools.

After installing the glass Apply a small amount of caulking on the edges. This will make the glass weatherproof. Install a glazier’s point on both sides of the frame. This will secure the pane. The points shouldn’t 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. Then make it into pencil-sized strips. The first strip should be glued to the corner of the frame. Work from one corner to another to ensure it’s even and smooth.

Glazier’s Points

The glazier’s points are tiny triangular pieces of steel which help to secure glass into a window frame without scratching or damaging the delicate surface. It’s easy to understand how to use this hidden tool and you can save money on the expense of an expert installation.

After taking off the old putty, glazier points and any leftovers, replace window pane clean the frame thoroughly with an utility knife. If needed it is necessary to lightly sand the wood in the rabbet grooves to smooth out rough spots. If you sand wood, protect it with painter’s tape to prevent accidental damage.

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

Place the new window in the frame and push it in place with your hand. Then, use the tip of your chisel, or the back end of the putty knife to pierce the glazier’s facets, as shown in Figure 11. The glazier’s points should sit aligned with the top edge of your pane, and the raised shoulders should be just below the lip.

Apply a small amount of glazing compound on 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 fully.

Install the new window sash once the glazing compound has dried. First, coat the wood with an even layer of linseed. This will prevent the newly-created putty drying out or cracking due to the moisture it absorbs. Apply the coat using a brush or the tip of your putty knife, then employ the chisel or back end from the putty knife to gently press the new sash and glazier’s tips into the rabbet grooves. Repeat this process at intervals of 10 inches all around the frame.


A baseball thrown or a rock thrown in error, or a tree falling could result in a broken or cracked window. Fortunately, windows can be easily replaced by simply putting a brand new piece in place. The glass is held in the position with a tiny metal clip, referred to as 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 using an abrasive and an abrasive scraper that is a pull type or the wood chisel. Wear protective glasses and gloves while working. You’ll require a heat gun when the window is fixed into the frame.

If you’re planning to install the original sash in the future, take care to remove the molding pieces that are used to secure the old pane. Then, sand the sash to ensure it’s level and ready for new caulk. Once the sash is installed and sanded, apply a fresh silicone caulk to the glass to ensure it doesn’t swell or fade over time.

Remove the glazing points from the rabbets and the grooves in the sash that the glass sits. If they’re hard to chisel, use the hand tool, such as a heating gun over them for a few minutes to soften them. If you’re using a heat gun, be cautious not to scratch the railings of the sash or the sash itself by holding the tool too close.

Once the old glaze points and putty have been removed prepare a bed for the new pane. Roll a rope made of glazing compound between your fingers and then make it about 1/2 inch thick. Then, press it into the rabbets where the glass will be. It is essential that the glass rests against the putty on each side 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 pressing it into the sash. Otherwise, you’ll need to apply putty on the crack to create an airtight seal and keep water out. After the putty has dried, clean the oily film off the glass using an abrasive and allow it to dry completely prior to painting. Paint after the putty has dried completely. It won’t form a good seal and could leak or discolor with time.


If you’ve suffered a break in a window pane, you might be worried about the cost of replacing it. In reality, replacing a single pane of glass doesn’t need to be expensive if you do it on your own. In fact even windows with double panes can be replaced for a fraction of the cost of an expert.

If you are working with a large glass window first, ensure that it is securely attached to the frame. With the right tools and techniques you can complete this task easily and fast.

When you are ready to start taking down the old window pane. Pry out the glazing points made of metal that are attached to it. These are tiny metal triangles which act as “nails”, holding the window in place. They are placed under a glaze putty or bead that hardens to solid wedge that holds the frame in place and hides the sharp edges.

After taking off the old pane clean the frame and wood. Scrape off any old paint, and sand the rabbet grooves where the glazing points were. These should be sanded down to bare wood, so that you can paint them the same shade as the rest of the frame. After the sanding process, apply a coat of flax oil to the bare wood to prolong its life.

Then, you need to measure the size of the window opening. You’ll need 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 you have the exact size for the new pane. This will allow for seasonal changes in the glass. Take these dimensions to a 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. 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.
