Glass

If your single-pane windows are outdated, deteriorating or broken replacing them with more modern insulated or tempered glass can increase energy efficiency and reduce noise while preserving the historic integrity of older homes. The majority of homeowners with basic hand tools can Replace window pane a window pane. You will also require an extra window pane, glazier's tips, pliers, and latex glaze putty. If necessary you may make use of a heat gun to warm the old putty. Wear safety glasses and gloves before you begin. Working with broken glass could cause serious injuries.

Remove any broken glass pieces remaining. It is best to use pliers however, a flathead may be used equally. Then, use a wooden chisel or putty knife remove the remaining old putty around the frame and sash. Take your time and work slowly, taking care not to break the existing window sash. This should be done on an elevated ladder, not on the ground. Also, ensure that someone lower to keep it in place.

Once you've removed all the old putty, you can prepare the window frame for the new pane. Find the width and the height of the opening in the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to a hardware or home center store to get an item cut from glass that is in stock to the correct size. Alternatively, you can cut the glass yourself if you have the right tools.

After installing the new pane, run a small bead of caulking along the edge to ensure it is weatherproof. Then, place a glazier's tip on the frame's opposite side to secure the pane into place. 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 to the surface, gently knead it until it is smooth and free from lumps. Then, roll it into pencil-size strips. The first strip should be placed to the corner of the frame, moving from one corner to the other so that it is smooth and even.

Glazier's Points

The glazier's points are small triangular pieces which help to secure glass into frames for windows without damaging or scratching the delicate surface. Understanding how to use these hidden tiny pieces of help is simple and could save you money on a professional installation or the cost of purchasing new glass.

After the old putty and the glazier's points have been removed, thoroughly clean the frame using a utility knife to eliminate any remaining traces. Lightly sand the wood in the rabbet grooves to smooth rough areas. If you do sand the wood, ensure you protect it with painter's tack to avoid accidental damage.

Note down the dimensions of the frame. These dimensions can be taken to an hardware or home centers store, and the new pane will be cut to a smaller size. This will ensure a tight fit, and allow for expansion and contraction.

Place the new window in the frame and press it into the frame by using your hands. Then use the point of your chisel or Replace window pane back end of the putty knife to pierce the glazier's points, as shown in Figure 11. When you're done, they should be flush with the top edge of the pane, and the shoulders that are raised of the points should be just below the rabbet's rim groove.

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

Install the new window replacement panes 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 drying out or cracking when it absorbs moisture. Apply this coat using a brush or the edge of your putty knife, and then use the chisel, or the back end of the knife to gently hammer the new sash and glazier's point into the rabbet grooves. Repeat this procedure every 10 inches along the perimeter of the frame.

Putty

A baseball hit or a rock thrown by error or a branch falling could result in a broken or cracked window pane. Most windows can be repaired easily by simply putting in a fresh piece. The glass is held in place using a small metal clip called a glazier's point, and putty, often called glazing compound. Remove the old pane and clean the area with an abrasive, pull-type scraper, or a wood chisel. Wear protective glasses and gloves while working. You'll need a heat gun if the window is glued into the frame.

If you are planning to replace the original sash in the future, take care to remove any pieces of molding that are used to secure the old pane. Sand the sash until it's flat and ready to receive new caulk. Once the sash is put back in place, you can apply a silicone caulk to the glass. This will ensure that it won't get soiled or discolor over time.

Take the glazing points out of the rabbets, the grooves in the sash that the glass is. If they're difficult to cut out, try holding the hand tool, such as a heat gun to soften them before you do. If you're using a heating gun, be cautious not to scratch the railings or sash by using the tool too close.

Create a bed for your new pane by removing the old glaze points and putty. Roll a rope 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 is positioned against the putty on each side, so if you need to tap it, gently press the glass into the rabbet with your thumb.

If the new pane has cracked, you can use the silicone caulk or glass glue based on solvents to seal the crack prior to pressing it into the sash. If the crack isn't sealed, you will require putty to keep water out. Once the putty is dry, wipe the oily film off the glass and allow it to dry completely before you paint. If you paint before the putty has completely dry, it won't form a strong seal and may leak or discolor in time.

Paint

You may be concerned about replacing a damaged piece of glass. But the truth is that replacing a single glass pane doesn't have to break the bank if you do it yourself. Even a double-paned window could be replaced for a fraction of the price it will cost a professional.

First, if you're working on a large window, make sure that it is securely fastened to the frame. With the right tools and techniques you can make this task relatively easy and quick.

Once you're ready to begin taking off the old window by prying out the metal glazing points that are connected to it. These are tiny metal triangles that act as "nails", holding the window in the frame. They are submerged beneath a glaze putty or bead that hardens to a solid wedge that holds the wood frame in place and conceals the edges.

After taking off the old pane clean the frame and the wood. Scrape off any old paint, and sand the rabbet grooves where the glazing points were placed. These should be sanded down to bare wood so that you can paint them the same color as the rest of the frame. After sanding the wood, apply a layer of flax oil. This will help prolong the life of the frame.

Next, measure the width of the window opening. You will need to measure the vertical and horizontal 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 seasonal change. You can bring these measurements to a hardware store or home improvement shop and have the glass cut for you.

Now, it's time to bed the new window pane. To do this, replace Window pane 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.
