Glass

If your single-pane windows are outdated broken, deteriorating or damaged replacing them with more modern glass that is tempered or insulated will increase energy efficiency and reduce noise while maintaining the historical integrity of older homes. The process of replacing the window pane is easy and can be completed by homeowners with basic hand tools. In addition to a new pane, the following tools are required: latex glazing putty; glazier's points; pliers; and an electric heater to warm the old putty if required. Wear safety glasses and gloves prior to beginning. Working with broken glass can cause serious injuries.

Take out any broken glass pieces remaining. This is best done using a pair of pliers, however, flathead screwdrivers can be used in a pinch. After that, use a wood chisel or putty knife remove the rest of the old putty from around the frame and sash. Be careful to not scratch the window sash. Work slowly and carefully. It is best to do this on a sturdy ladder instead of the ground, and to place someone on the sash in order to help hold it in place.

Once you've removed all the old putty, it is time to prepare the window frame to accommodate the new pane. To allow for seasonal expansion or contraction by subtracting 1/8 inch 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 cut the glass yourself if you have the appropriate tools.

After installing 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 ensure the pane. The points shouldn't be too tight that they create friction between the frame and the sash However, they should not be loose.

Before applying the putty, make sure to knead it until it is soft and free of lumps. Make 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 facets are small triangular pieces that allow glass to be secured into frames for windows without scratching or damaging the delicate surface. Knowing how to use these hidden little helpers is easy and could save you money on a professional installation or the cost of purchasing new glass.

After taking off the old putty, glazier points and any residue Clean the frame thoroughly with an utility knife. Lightly sand the wood into the rabbet grooves if needed to smooth out rough areas. If you sand wood, protect it with painter’s tape to protect it from damage caused by accidental sanding.

Note down the dimensions of the frame. Take these measurements to an hardware store or home center, and have the new pane cut slightly smaller than the frame's opening. This will ensure that the pane fits snugly and allows for expansion and contraction.

Place the new pane into the frame and push firmly using your hands. Then, you can use the point of your chisel or the back of the putty knife to pierce the glazier's facets, as shown in Figure 11. When you're done taping, they should be in line with the top edge of the pane. the shoulders that are raised of the points should be below the rabbet's lip. groove.

Apply a small amount of glazing compound on the edges of the new glass and into the rabbet grooves, to seal and protect them. Let it dry completely and cure.

Install the new window sash when the glazing compound has dried. The first step is to coat the wood with a heavy coat of Linseed oil. This will stop the new putty drying out or cracking when it absorbs moisture. Use a brush to apply this coat, or the point of the blade. Then use the chisel that is on the back of the putty tool or the back of the handle to gently hammer the new sash or glazier's point into rabbet grooves. Repeat this process in intervals of 10 inches all around the frame.

Putty

A baseball thrown at you or an unintentional rock, or a falling branch can cause a window pane to break or crack. Fortunately, replace window pane windows can be repaired by simply putting a brand new piece in place. The glass is held in place with a small metal clip called a glazier's point, and putty, also called glazing compound. Before you install a new pane, first get rid of the old one and clean the area using a rag and the pull-type paint scraper or a wood chisel. Wear protective glasses and gloves while working. You'll need a heat gun in the event that the window is glued into the frame.

If you are planning to replace the original sash in the future, take care to remove any 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 it is possible to apply a silicone caulk over the glass. This will ensure that it doesn't be leaking or fade over time.

Take the glazing points out of the rabbets, the grooves in the sash, where the glass sits. If they're hard to chisel out, you can try holding the hand tool, such as a heat gun to soften them up first. When using a heated tool, be sure to not scratch the sash and its railings.

Make a bed for your new pane after removing the old putty and glazing points. Roll a piece of glazing compound between your hands, and form it into a 1/2-inch thick. Place it into the rabbets, where the glass will be put. The glass should rest against the putty on both sides. If needed you want to tap your glass lightly into the rabbet with your thumb.

If the new pane has cracked, you can apply the silicone caulk or glass glue based on solvents to seal the crack prior to pressing it into the sash. If not, you'll have to apply putty over the crack to form a tight seal and keep water out. After the putty has dried, wipe the oily film off of the glass and allow it to dry completely before you paint. If you paint before the putty is fully dry, it won't create a solid seal and could be leaking or discoloring over time.

Paint

You might be worried about replacing a damaged piece of glass. The truth is, replacing a single piece of glass doesn't have to be costly when you do it on your own. In fact windows with replacement double glazed window panes can be replaced at a fraction of the cost of a professional.

First, if you are working on a large-sized window, make sure that it is securely fastened to the frame. By using the correct tools and techniques you can make this task relatively easy and speedy.

When you are ready to begin taking down the old window pane. Pry out the metal glazing points that are attached to it. These are essentially small metal triangles which function as "nails" which hold the window in within the frame of wood. They are submerged under a bead of glazing putty, which is then cured to form a solid, moulded wedge which holds the window in place and conceals the edges.

After removal of 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 to bare wooden surfaces, allowing you to paint the frames the same color. After sanding, apply a layer of flax oil on the wood's surface to help extend its lifespan.

Next, 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. 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 seasonal change. Take these dimensions to your local hardware or home improvement store, and they will have 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.
