A damaged window pane can be a nuisance. It could be a chance to upgrade your windows to energy efficient or insulated ones and enjoy advantages like improved comfort, increased resale value and reduced utility costs.
This is a project you could take on yourself for only a fraction of the cost of hiring an expert. It requires the right equipment and an hour or two of your time.
Glass
Replace your old single-paned windows with tempered or insulated glass to increase the efficiency of your energy, reduce noise, and protect the original character of your old home. The procedure of replacing the window pane is easy and can be accomplished by anyone with basic hand tools. You will also require an extra window pane, glazier's tips, pliers, and latex glazing putty. If needed you can use a heatgun to warm the old putty. Wear safety goggles and gloves prior to beginning. Working with broken glass can cause serious injuries.
Begin by removing any remaining broken pieces of glass. It is recommended to use pliers however,
replace window Pane a flathead may be useful equally. After that, use a wood chisel or putty knife remove the rest of the old putty from the frame and sash. Take your time and work slowly and be careful not to break the current window sash. It is recommended to do this on a stable ladder instead of the ground and to have someone standing below the sash in order to help hold it in place.
Once you've removed all the old putty, prepare the window frame for the new pane. Measure the width and height of the opening in the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Bring these measurements to a hardware store or home center, and have a piece of stock glass cut to size. Alternately, you can cut the glass yourself if you have the appropriate tools.
After installing the new glass After installing the glass, apply a small amount of caulking to the edge. This will make the glass weatherproof. Install a glazier's point on both sides of the frame. This will help secure the pane. The points shouldn't be so tight that they cause friction between the sash and the frame however they shouldn't be too loose.
Before applying the putty, work it in a gentle manner until it's soft and free of lumps. Cut it into pencil-sized pieces. Apply the first strip to the frame's corner. Work from corner to corner to ensure it's even and smooth.
Glazier's Points
The glazier's points are tiny triangular pieces of steel that help secure glass into frames for windows without scratching or damaging the fragile surface. It's easy to understand how to use this secret tool and you can save money on the cost of an installation by a professional.
After the old putty and glazier's points are removed Clean the frame thoroughly with a knife to eliminate any remaining residue. If necessary you can lightly sand the wood along rabbet grooves to smooth out rough spots. If you sand wood cover it with painter's tape to protect it from damage caused by accidental sanding.
Note down the dimensions of the frame. These dimensions can be taken to an hardware or home centers store, and the new frame will be cut to a smaller size. This will ensure a tight fit and will allow room for expansion and contraction.
Place the new pane into the frame and push firmly using your hands. Make use of the chisel's point or the back of the putty knife to tap the glazier's points as shown in Figure 11. The glazier's points should sit flush against the top edge of your pane, and the shoulders should be just below the lip.
Apply a thin layer glazing compound on the rabbet grooves and edges of the new glass. This will protect and seal the edges. Allow it to dry and cure fully.
When the glazing compound is dry, you're ready to install the new window sash. First, coat the wood with an even layer of linseed. This will prevent the new putty from soaking in the moisture and drying out and cracking with time. Apply this coat using a brush or the tip of your knife, and then employ the chisel or back end from the putty knife to gently hammer in the new sash and glazier's points into the grooves of the rabbet. Repeat this procedure every 10 inches along the perimeter of the frame.
Putty
A baseball thrown, a rock thrown in error, or a tree falling can cause a broken or cracked window. Most windows can be repaired easily by putting in a new piece. The glass is held in place with tiny metal clips known as a glazier's point, and putty, also called glazing compound. Before installing a new pane, first get rid of the old one and clean up the area with an abrasive and an abrasive scraper that is a pull type or the wood chisel. Wear safety glasses and gloves when working. You'll need a heat gun if the window is glued into the frame.
If you're planning to install the original sash in the future, take care to remove any molding pieces that secure the old pane. Sand the sash until it is flat and ready to receive new caulk. After the sash has been re-installed, apply a new caulk made of silicone around the glass to ensure that it doesn't swell or fade over time.
Take the glazing points out of the rabbets and the grooves in the sash that the glass is. If they're difficult to chisel, hold the hand tool, such as a heatgun over them to allow them to soften before. If you're using a heated gun, make sure not to damage the railings of the sash or the sash itself by using the tool too close.
Once the old glaze points and putty have been removed, make a bed for the new pane. Roll a rope made of glazing compound between your fingers and make it around 1/2 inch thick. Press it into the rabbets, where the glass will be placed. The glass must be positioned against the putty on both sides. If you need to you want to tap your glass lightly into the rabbet with your thumb.
If the new pane has a crack then you can seal it with a solvent-based glue or silicone caulk prior pressing it into the sash. If the crack is not sealed, you'll need to use putty to keep water out. Once the putty is dry remove the oily film off the glass and allow it to dry completely before painting. If you paint before the putty has completely dry, it won't form a solid seal and could discolor or leak in time.
Paint
You may be concerned about replacing a broken piece of glass. But the truth is that replacing a single glass pane doesn't require a huge amount of money when you do it yourself. Even a
double glazing replacement window-paned window can be replaced for a fraction of the price it will cost for a professional.
If you're working with a large glass window, first make sure it is securely attached to the frame. By using the correct tools and techniques to make this task relatively easy and fast.
Once you're ready to begin, begin by removing the old window pane by prying out the glazing points made of metal that are attached to it. These are tiny metal triangles that act as "nails", holding the window in place. They are submerged beneath a layer of glazing putty, which transforms into a solid moulded wedge which holds the window in place and conceals the edges.
After removing the old pane, clean the frame and wood. Scrape off any paint and sand down the rabbet grooves, where the glazing points were. Sand them down to bare wooden surfaces so you can paint the frames the same shade. After sanding, apply a coat of flax oil to the wood's surface to extend the life of the frame.
Then, take measurements of the dimensions of the window opening. You'll need to determine the horizontal and vertical dimensions of the entire opening, as well as the thickness. To determine the exact dimensions of the new pane, subtract 1/8 inch from both measurements. This will also allow for expansion and contraction of the glass during seasons of changes.
