How to Replace Window Panes
A cracked window pane is an inconvenience. This can be an opportunity to upgrade to energy-efficient windows or insulated ones to enjoy benefits like increased comfort, higher resale value and lower utility costs.
You can do it yourself for a less than what it would cost to employ an expert. It requires the right equipment and an hour or two of your time.
Glass
Replace your single-paned windows with tempered or insulation glass to improve energy efficiency, reduce noise, and preserve the historic integrity of your older home. Most homeowners with basic hand tools can replace windows with ease. You will also need an additional window pane, glazier's tips, pliers, and latex glaze putty. If you need to you may make use of a heat gun to warm the old putty. Before beginning, wear gloves and safety glasses as working with broken glass can cause injuries.
Remove any broken glass pieces remaining. This is best done using pliers, but a flathead screwdriver can also be used in the pinch. After that, use a wood chisel or putty knife to remove the remaining old putty from around the frame and the sash. Work slowly and carefully and be careful not to damage the old window sash. It is recommended to work using a sturdy ladder rather than on the ground and to place someone on the sash to help hold it in place.
Once you have removed all the old putty, you can prepare the window frame for the new pane. To allow for seasonal expansion or contraction, subtract 1/8 inch each from the measurements of width and height. Take these measurements to the nearest hardware store or home center, and get a piece of stock glass cut to size. You can also cut the glass yourself if you have the right tools.
After installing the new glass Apply some caulking on the edges. This will make the glass weatherproof. Then, place a glazier's tip on the frame's opposite side to hold the pane in place. The points should not be tight enough to create friction between the frame and sash however they should not be loose.
Before applying the putty, knead it thoroughly until it's soft and free of lumps. Then, roll it into pencil-size strips. Apply the first strip to the corner of the frame. Work from one corner to the next, making sure it is even and smooth.
Glazier's Points
The glazier’s points are small triangular metal pieces which help to secure the glass into the window frame without damaging the delicate surface. Knowing how to use these hidden tiny pieces of help is simple and could save you money on a professional installation or the cost of new glass.
Once the old putty and glazier's points are removed, thoroughly clean the frame with a knife to eliminate any remaining traces. If necessary, lightly sand the wood in the grooves of the rabbet to smooth out rough areas. If you sand wood protect it with painter's tape to prevent accidental damage.
Note down the exact dimensions of the frame. These measurements can be brought to a home center or hardware store, and the new frame will be cut slightly smaller. This will ensure that the pane fits snugly and allows for expansion and contraction.
Insert the new pane into the frame and push firmly with your hands. Use the point of the chisel or the edge of the putty blade to tap in the glazier's points, as shown in Figure 11. The glazier's points should sit flush against the top edge of the pane and the shoulders should be just below the lip.
Apply a thin layer of glazing compound on the edges of the new glass and in the rabbet grooves, to seal and protect them. Allow it to dry completely and cure.
Install the new window sash after the glazing compound has dried. The first step is to coat the wood with a thick coat of linseed oil. This will prevent the new putty from sucking 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 tool or the back of the handle to gently hammer the new sash or glazier's point into the grooves of the rabbet. Repeat this process every 10 inches around the perimeter of the frame.
Putty
A baseball hit or a rock thrown in error or a branch falling can result in a cracked or cracked window pane. Most windows can be replaced by putting in a new piece. The glass is held in place by small clips made of metal called a glazier's point, and putty, which is often called glazing compound. Before you install a new pane, first get rid of the old one and clean the area using an abrasive and the pull-type paint scraper or the wood chisel. Wear gloves and safety glasses while doing this work. If the window is glued to the frame, you'll need to use a heat gun to soften the adhesive before cutting it loose.
If you are planning to replace upvc window handle the original sash in the future, take care to remove any molding pieces that secure the old pane. Then, sand the sash to ensure it's level and ready for new caulk. After the sash has been put back in place then, you can apply a silicone caulk over the glass. This will ensure that it won't be leaking or fade over time.
Take out the glazing points in the rabbets. These are the grooves on the sash, which is where the glass is. If they are hard to chisel, hold a hand tool such as a heatgun over them for a few minutes to soften them. When using a heating tool, be sure to not scratch the sash or its railings.
Prepare the bed for your new pane after you have removed the old putty and glazing points. Roll a piece of glazing compound between your hands, and form it to be around 1/2-inch thick. Then, you can press it into the rabbets where the glass will sit. The glass must be positioned against the putty on both sides. If necessary, lightly tap your glass into the rabbet with your thumb.
If the new pane is cracked, you can apply the silicone caulk or glass glue based on solvents to cover the crack prior to pressing it into the sash. If the crack is not sealed, you will need to apply putty to keep the water out. After the putty has dried remove the oily film off of the glass and allow it to dry completely before you paint. If you paint before the putty has completely dry, it won't create a strong seal and may leak or discolor in time.

You might be worried about replacing a broken piece of glass. In reality, replacing a single pane glass doesn't need to be costly if you do it on your own. In fact even windows with double panes can be replaced at only a fraction of the cost of a professional.
If you're working with a large glass window first, ensure that it is securely attached to the frame. Using the proper tools and techniques, you can complete this task easily and fast.
Once you're ready to begin, begin by removing the old window pane by removing the glazing points made of metal that are attached to it. These are small metal triangles that function as "nails" to hold the window in place. They are buried beneath a bead or glazing glue that hardens to an unbreakable wedge that holds the wood frame in place and hides the points.
After you have the old pane removed, clean up the surrounding frame and wood. Scrape off any paint and sand down the rabbet grooves, where the glazing points were. Sand them to bare wooden surfaces so you can paint the frames with the same color. After sanding, apply a layer of flax oil on the wood's surface to prolong its life.
Then, you need to measure the width of the window 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 allow for seasonal changes in the glass. You can bring these measurements to a hardware store or Window.replacement near me home improvement shop 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.
