A cracked window pane is a nuisance. This could be an opportunity to upgrade your windows to energy efficient or insulated ones and enjoy advantages like improved comfort, increased resale values and lower utility costs.

You can do it yourself for a fraction of what it would cost to employ an expert. You'll only require the proper tools and a few minutes of your time.

Glass

Replace your old single-paned windows with tempered insulated glass to increase energy efficiency, cut down on noise, and maintain the historic integrity of your older home. The majority of homeowners with basic hand tools can repair a window pane. Alongside a replacement window glass pane, the following tools are required such as latex glazing putty; Glazier's points; pliers and the use of a heat gun to warm the old putty if required. Wear safety goggles and gloves before you begin. Working with broken glass could cause serious injuries.

Remove any broken glass pieces that remain. This is best done using pliers, however, flathead screwdrivers can be effective in the pinch. Utilize a wood chisel or putty knives, to take away any remaining old putty around the frame and the window sash. Be careful to not damage the window sash. Work slowly and carefully. It is a good idea to work on a stable ladder instead of the ground and to have someone standing below the sash to help hold it in place.

After you've removed all the old putty, prepare the window frame to fit the new pane. Find the width and the height of the sash opening, 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. Alternately, you can cut the glass yourself if you have the tools you need.

After putting the new pane in place After installing the new pane, apply a small amount of caulking along the edge to ensure it is weatherproof. Install a glazier's point on both sides of the frame. This will ensure the pane. The points should not be so tight that they cause friction between the frame and sash, but they should also not be loose.

Before putting the putty on, work it in a gentle manner until it is soft and free of lumps. Roll it into pencil-sized strips. Place the first strip to the corner of the frame, moving from one corner to the next to ensure it is even and smooth.

Glazier's Points

The glazier's points are small triangular pieces of metal that allow glass to be secured into a window frame without scratching or damaging the delicate surface. Understanding how to use these hidden tiny pieces of help is simple and can save you money on professional installation or the cost of buying new glass.

After removing the old putty, glazier points and any remnants, clean the frame thoroughly with an utility knife. Lightly sand the wood in the rabbet grooves to smooth rough areas. If you sand wood, protect it with painter’s tape to prevent accidental damage.

Take measurements of the empty frame and write down accurate measurements. These measurements can be taken to a home center or hardware store and the new pane will be cut a bit smaller. This will ensure a tight fit and leave room for expansion and contraction.

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

Apply a thin layer glazing compound to the rabbet grooves and edges of the glass. This will protect and seal the edges. Allow it to dry and cure fully.

Install the new window sash once 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 taking in the moisture and drying out and cracking with time. Apply this coat with a brush or the tip of your knife, then employ the chisel or back end of the putty knife to gently hammer in the new sash and glazier's point into the rabbet grooves. Repeat this process in intervals of 10 inches all around the frame.

Putty

A baseball that is thrown or an unintentional rock, or a fallen branch can cause a window to crack or break. Most windows can be replaced by putting in a new piece. The glass is held in place by tiny metal clips known as a glazier's point and putty, also called glazing compound. Remove the old pane and clean the area using a rag, a pull-type scraper, or a wood chisel. Wear gloves and safety glasses when working. If the window is secured to the frame, you'll have to make use of a heat gun to soften the adhesive before cutting it loose.

If you're planning to replace your original sash, you must remove the molding that supports the old pane. Sand the sash until it's flat and ready to receive new caulk. Once the sash is re-installed and sanded, apply a fresh silicone caulk around the glass to ensure that it won't leak or discolor in time.

Remove the glazing points in the rabbets. These are the grooves in the sash where the glass is. If they're difficult to work out, try holding a hand tool like a heat gun to soften them first. When using a heat tool, make sure to avoid damaging the sash and its railings.

Once the old glaze points and putty are removed, prepare a bed for the new pane. Roll a piece of glazing compound between your hands, shaping it to be about 1/2-inch thick. Then, push it into the rabbets in which the glass will rest. The glass must rest against the putty on both sides. If needed you want to tap your glass lightly into the rabbet using your thumb.

If the new pane is cracked, you can cover it with a solvent-based glue or silicone caulk before pressing it into the sash. If not, you'll have to apply putty over the crack to create a tight seal and keep water out. After the putty is dry, clean the oily film off the glass with the help of a rag. Allow it to completely dry before painting. Paint before the putty has completely dried. It won't make a strong seal and could discolor or leak over time.

Paint

You may be concerned about replacing a broken pane of glass. But the truth is that replacing a single glass pane doesn't have to break the bank If you can do it yourself. Even a double-paned window could be replaced for a fraction of what it costs a professional.

First, if you're working on a large-sized window, make sure it is securely fastened to the frame. This can be made relatively simple and fast using the appropriate tools and techniques.

Once you're ready to begin with the removal of the old window pane by removing the metal glazing points that are connected to it. They are basically tiny metal triangles that function as "nails" that hold the window in place in the wood frame. They are buried beneath a bead or glazing putty that sets to form a solid wedge that holds the frame firmly in position and conceals the edges.

After 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 where the glazing points were. Sand them down to bare wooden surfaces, allowing you to paint the frames the same shade. After sanding, replace Window pane apply a coat of flax oil to the wood that is not sanded down to prolong its life.

Next, measure the dimensions of the window's opening. You will need to take horizontal and vertical measurements of the entire opening, and also the thickness of the old pane. Subtract 1/8 inch from each measurement to ensure you get the exact measurement for the new pane. This will also allow for expansion and contraction of the glass during seasons of changes. You can bring 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.
