Glass

If your single-pane windows are old broken, deteriorating or damaged replacing them with modern insulated or tempered glass can increase energy efficiency and decrease noise while also preserving the original character of older homes. The process of replacing a window pane is relatively easy and can be completed by anyone with basic hand tools. You'll also require an additional window pane, glazier's tips, pliers, and latex glazing putty. If needed you may make use of a heat gun to warm the old putty. Wear safety goggles and gloves before you begin. Working with broken glass could result in serious injuries.

Take away any broken glass pieces that remain. It is recommended to use pliers however a flathead could be useful as well. Then, use a wood chisel or putty knife to remove the rest of the old putty from the frame and sash. Be careful not to break the window sash. Work slowly and carefully. This is best done on an elevated ladder, not on the ground. Also, ensure that someone below the sash keep it in place.

Once you've removed all the old putty, prepare the window frame for the new pane. To allow for seasonal expansion or contraction and contraction, subtract 1/8 inch from the measurements of the width and height. Bring these measurements to the nearest hardware store or home center and find a piece glass cut to size. Alternately, you can cut the glass yourself, if you have the tools you need.

After putting in the new pane After installing the new pane, apply a small amount of caulking around the edges to ensure it is weatherproof. Then, place a glazier's tip on the frame's opposite side to secure the pane in its place. The points shouldn't be tight enough to cause friction between the frame and sash However, they should not be loose.

Before applying the putty on the surface, knead thoroughly until it is soft and free of lumps. Then, roll it into pencil-size strips. Apply the first strip to the frame's corner. Work from corner to corner and ensure that it is even and smooth.

Glazier's Points

The glazier's facets are tiny triangular pieces of steel that allow glass to be secured into the frame of a window 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 buying new glass.

After the old putty as well as the glazier's points have been removed Clean the frame thoroughly with a utility knife to eliminate any remaining traces. If necessary, lightly sand the wood in the grooves of the rabbets to smooth rough spots. If you do sand the wood, make sure to protect it with painter's tack to avoid accidental damage.

Write down the dimensions of the frame. Take these measurements to an hardware store or home center, and have the new pane cut smaller than the frame's opening. This will ensure a secure fit and leave room for expansion and contraction.

Place the new pane into the frame and push firmly using your hands. Use the point of the chisel or the back of the putty blade to tap the glazier's points as illustrated in Figure 11. The glazier's points should sit in line with the top edge of your pane and the shoulders raised should be just below the lip.

Apply a thin layer glazing compound on the rabbet grooves and edges of the glass. This will seal and protect the edges. Let it dry and cure completely.

When the glazing compound is dry, you're ready to install the new window sash. First, coat the wood with a thick coat of linseed oil. This will prevent the new putty from taking up the moisture and drying out and cracking with time. Apply this coat with a brush or the edge of your putty knife, and then use the chisel or the back end of the knife to gently press the new sash and glazier's points into the rabbet grooves. Repeat this process in intervals of 10 inches all around the frame.

Putty

A baseball that is thrown, an errant rock or a falling branch can cause a window to crack or break. Fortunately, windows can be replaced by simply placing a new piece of glass in its the proper place. The glass is held in place using a small metal clip called the glazier's pointed and putty, also called glazing compound. Before installing a replacement pane, first remove the old one and clean the area with a rag and the pull-type paint scraper or a wood chisel. Wear protective glasses and gloves when working. You'll need a heating gun if the window seal replacement is glued to the frame.

If you plan to reinstall the original sash in the future, take care to remove the molding pieces that are used to secure the old pane. Sand the sash until it's flat and ready to receive new caulk. After the sash has been reinstalled it is possible to apply a silicone caulk over the glass. This will ensure that it doesn't leak over time or discolor.

Remove the glazing points in the rabbets. These are the grooves in the sash, where the glass is located. If they're hard to chisel out, try placing a hand tool like a heat gun over them to soften them first. When using a heated tool, be careful to not scratch the sash and its railings.

Once the old points of glazing and putty are removed, prepare a bed for the new pane. Roll a piece of glazing compound between your hands, and form it to be around 1/2-inch thick. Press it into the rabbets where the glass will be put. It's important that the glass sits on the putty in all places on each side If you have to do so, gently tap the glass into the rabbet with your thumb.

If the new pane is cracked, you can use the silicone caulk or Replace Window pane glass glue that is based on solvents to fill in the crack before pressing it into the sash. If the crack isn't sealed, you'll need to use putty to keep water from getting in. Once the putty is dry clean the oily film off the glass and let it dry completely before painting. Paint before the putty has completely dried. It will not form a good seal and could discolor or leak over time.

Paint

You might be worried about replacing a damaged piece of glass. But the truth is that replacing one glass pane does not require a huge amount of money If you can do it yourself. Even double-paned windows can be replaced for a fraction of what it would cost a professional.

First, if you're working on a large-sized window, make sure it is securely fastened to the frame. This can be done relatively easy and fast with the right tools and techniques.

If you're ready to begin, begin by removing the old window pane by prying out the metal glazing points that are connected to it. They are basically tiny metal triangles that function as "nails" that hold the window in within the frame of wood. They are submerged beneath a layer of glazing putty that is then cured to form a solid, molded wedge that holds the window firmly in place and conceals the window's points.

After you have the old pane taken away clean 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, allowing you to paint the frames the same color. After sanding, apply a layer of flax oil to the wood's surface to help extend its lifespan.

Then, you need to measure the width of the window opening. You will need to take vertical and horizontal measurements of the entire opening, as well as the thickness of the old pane. To determine the exact size of the new pane, subtract 1/8 inch from both measurements. This will allow for seasonal changes in the glass. Bring these measurements 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.
