A damaged window pane could be a nuisance. This can be an opportunity to upgrade your windows to energy efficient or insulated ones, and reap benefits like increased comfort, increased resale values and lower utility costs.
You can do it yourself at a fraction of what it would cost to employ an expert. You'll only require the appropriate tools and a few minutes of your time.
Glass
Replace your old single-paned windows with tempered or insulation glass to improve energy efficiency, cut down on noise, and protect the historic integrity of your older home. Most homeowners with basic hand tools can replace windows with ease. You'll also require an additional window pane, glazier's tips, pliers, and latex glazing putty. If necessary, you can use a heating gun to warm the old putty. Before starting, put on gloves and safety glasses as working with broken glass could cause injuries.
Take away any broken glass pieces that remain. This is best done using pliers, though using a flathead screwdriver may be effective in the pinch. Utilize a wood chisel or putty knives to remove any old putty remaining around the frame and window sash. Work slowly and carefully making sure not to break the existing window sash. It is best to work using a sturdy ladder rather than the ground and have someone standing below the sash to help keep it steady.
Make sure that the window frame is ready to accept the new pane after you have removed the old putty. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of width and height. Take these measurements to a hardware store or home center, and find a piece glass cut to size. You can also cut the glass yourself if have the tools you need.
After putting in the new glass After installing the glass, apply some caulking to the edge. 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 create friction between the frame and sash, but they also shouldn't be loose.
Before applying the putty make sure to knead it until it is smooth and free of lumps. Then, roll it into pencil-size strips. Apply the first strip to the frame's corner. Work from one corner to another and ensure that it is even and smooth.
Glazier's Points
The glazier's points are the tiny triangular pieces of steel which help to secure glass into the frame of a window without scratching or damaging the fragile surface. Knowing how to use these tiny helpers is simple and could save you money on professional installation or the cost of buying new glass.
After the old putty and the glazier's point are gone, thoroughly clean the frame with a knife to eliminate any remaining residue. Lightly sand the wood into the rabbet grooves to smooth rough areas. If you decide to sand wood, protect it with painter's tape to avoid accidental damage.
Measure the empty frame's dimensions and record precise measurements. These measurements can be brought to a home center or hardware store, and the new pane will be cut slightly smaller. This will ensure that the pane fits perfectly and allows for expansion and contraction.
Place the new pane in the frame and push it in place by using your hands. Then, you can use the point of your chisel or back end of the putty knife to pierce the glazier's points as shown in Figure 11. The glazier's point should be aligned with the top edge of your pane, and the shoulders should be just below the lip.
Apply a thin layer of glazing compound to the rabbet grooves as well as the edges of the new glass. This will seal and protect the edges. Allow it to dry and cure fully.
Install the new window
sash window replacement after the glazing compound has dried. First, coat the wood with a thick layer of linseed. This will prevent the new putty drying out or cracking due to the moisture it absorbs. Use a brush to apply this coat, or
Replace Window Pane even the tip of the putty blade. Then use the chisel on the back of the putty tool or the back of the handle to gently hammer the new sash or glazier's point into the rabbet grooves. Repeat this procedure every 10 inches along the frame's perimeter.
Putty
A baseball thrown at you or an unintentional rock, or falling branch could cause a window pane to break or crack. Fortunately, the majority of windows can be repaired by simply placing a new piece of glass in its place. The glass is held in position by a small metal clip, referred to as the glazier's point, and putty. This compound is also known as glazing compound. Remove the old pane and clean the area with the rag, a pull-type scraper, or a wood chisel. Wear gloves and safety glasses while working. You'll need a heat gun when the window is fixed into the frame.
If you are planning to replace the original sash, remove the molding pieces that secure the old pane. Then sand the sash to make sure it's flat and ready for new caulk. Once the sash is installed and sanded, apply a fresh caulk made of silicone around the glass to ensure that it won't leak or discolor over time.
Remove the glazing points from the rabbets, or the grooves in the sash where the glass is. If they're hard to chisel out, try placing the hand tool, such as a heat gun to soften them up first. If you're using a heat gun, be careful not to scratch the sash or its railings by holding the tool too close.
Make a bed for your new pane after you have removed the old glaze points and putty. Roll a piece of glazing compound between your hands, shaping it to be around 1/2-inch thick. Then, you can press it into the rabbets in which the glass will sit. It's important that the glass sits on the putty in all places on each side So if you have to tap it, gently press the glass into the rabbet with your thumb.
If the new pane is cracked then you can seal it with a solvent-based glass glue or silicone caulk prior to pressing it into the sash. In other cases, you'll need to putty over the crack to create an impervious seal to keep water out. After the putty has dried clean the oily film off of the glass and allow it to dry completely before you paint. If you paint before the putty is completely dry, it will not form a solid seal and could leak or discolor in time.
Paint
If you've suffered a break in a window pane, you may be worried about the cost of replacing it. But the truth is that replacing one glass pane does not need to cost a fortune If you can do it yourself. Even a double-paned window can be replaced for a fraction of the price it would cost an expert.
If you are working with large glass windows first ensure it is securely fixed to the frame. This job can be done relatively easy and fast using the appropriate tools and techniques.
When you are ready to start taking down the old window pane. Take out the glazing points made of metal that are attached to it. These are essentially small metal triangles which function as "nails" that keep the window in place in the wood frame. They are buried beneath a glaze putty or bead which hardens into a solid wedge that holds the frame securely in place and conceals the edges.
Once you have the old pane taken away, clean up the surrounding frame and wood. Scrape off any paint that has been used and sand the rabbet grooves that the glazing points were placed. These should be sanded to the point of being bare, so that you can paint them the same shade as the rest of the frame. After sanding, apply a coat of flax oil on the wood's surface to help extend its lifespan.
Then, take measurements of the dimensions of the window opening. You'll need to determine the vertical and horizontal 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.
