You can do it yourself for a less than what it would cost to employ an expert. You only need the right tools and a few hours of your time.

Glass

If your single-pane windows are outdated damaged, cracked or deteriorating replacing them with modern glass that is tempered or insulated will improve energy efficiency and reduce noise while preserving the original character of older homes. The majority of homeowners with basic hand tools can repair the window pane. Alongside a replacement pane, the following items are required: latex glazing putty; pliers, glazier's points and a heat gun for warming the old putty, if necessary. Before starting, wear gloves and safety glasses as working with broken glass could cause injuries.

Take out any broken glass pieces that remain. It is recommended to use pliers, but a flathead can work equally. Utilize a wood chisel or putty knife to get rid of any old putty remaining around the frame and window sash. Be careful and slow making sure not to damage the old window sash. This should be done on a ladder, not the ground. Also, ensure that someone on the ground to hold it steady.

Prepare the window frame to receive the new pane once you have removed the old glue. Measure the width and height of the opening for the sash and subtract 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to the nearest hardware store or home center, and have a piece of stock glass cut to size. You can cut the glass yourself if you possess the appropriate tools.

After putting in the new pane after installing the new pane, put a tiny amount of caulking along the edge to ensure it is weatherproof. Then, place a glazier's tip on each side of the frame to hold the pane in its place. The points shouldn't be so tight that they create friction between the frame and sash but they shouldn't be too loose.

Before applying the putty on the surface, you must knead it thoroughly until it is soft and free of lumps. Then, roll it into pencil-size strips. Place the first strip in the corner of the frame, moving from one corner to another to ensure it is even and smooth.

Glazier's Points

The glazier's points are tiny triangular pieces of steel that help secure glass into a window frame without scratching or damaging the fragile surface. It's simple to learn how to use this hidden tool and you can save money on the cost of a professional installation.

After taking off the old putty, glazier points, and any other residue clean the frame thoroughly using an utility knife. If needed you can lightly sand the wood along the grooves of the rabbet to smooth rough spots. If you do sand the wood, ensure you protect it with painter's tape to avoid accidental damage.

Take measurements of the empty frame and note down precise measurements. These measurements can be taken to the hardware or home center store, and the new frame will be cut to a smaller size. This will ensure that the pane fits perfectly and allows for expansion and contraction.

Place the new pane into the frame and push it in place with your hand. Then use the point of your chisel or the back end of the putty knife to make a tap on the glazier's points as shown in Figure 11. After you're done, the points should be in line with the top edge of the pane. the raised shoulders of the points should be just below the rabbet's rim groove.

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

After the glazing compound dries it's time to put in the new window sash. First, coat the wood with an even layer of linseed. This will stop the new putty from taking up moisture and drying out and cracking over time. Apply the coat using a brush or Replace Window Pane the tip of your knife, then use the chisel, or the back end of the putty knife to gently press the new sash and glazier's points into the rabbet grooves. Repeat this process every 10 inches around the perimeter of the frame.

Putty

A baseball hit, a rock thrown in error, or a fallen tree can result in a cracked or cracked window pane. The majority of windows can be replaced easily by putting in a new piece. The glass is held in place by a small metal clip called a glazier's point, and putty, also called glazing compound. Before installing a new pane, first get rid of the old one and clean the area using the help of a rag, the pull-type paint scraper or a wood chisel. Wear protective glasses and gloves while doing this work. If the window is glued to the frame, you'll need to employ a heat gun in order to soften the adhesive prior to cutting it loose.

If you're planning to reinstall your original sash, remove the mold that holds the old pane. Sand the sash until it is 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 leak over time or discolor.

Remove the glazing points from the rabbets. These are the grooves in the sash, where the glass is located. If they're difficult to work out, you can try holding an instrument like a heat gun to soften them up first. When using a heat tool, make sure to not scratch the sash's railings and sash.

Prepare the bed for your new pane by removing the old putty and glazing points. Roll a rope of glazing compound between your hands, forming it into a 1/2-inch thick. Place it into the rabbets, where the glass will be placed. It is crucial that the glass sits on the putty on each side, so if you need to tap it, gently press the glass into the rabbet using your thumb.

If the new pane is cracked, you can use the silicone caulk or glass glue made from solvents to cover the crack before pressing it into the sash. If the crack is not sealed, you'll need to apply putty to keep the water out. After the putty has dried and the film is oily, wipe it off the glass using an abrasive and allow it to dry completely prior to painting. If you paint before the putty has completely dry, it will not form a strong seal and may be leaking or discoloring over time.

Paint

If you've suffered a break in a window pane, then you may be worried about the expense of replacing it. The truth is, replacing a single pane of glass doesn't have to be costly when you do it on your own. In fact windows with double glazed window replacement panes can be replaced for only a fraction of the cost of a professional.

If you are working on a large-sized window, make sure that it is securely fastened to the frame. This can be done relatively easy and quick with the proper tools and techniques.

When you are ready to begin with the removal of the window pane. Take out the glazing points made of metal that are attached to it. They are basically tiny metal triangles that act as "nails" that keep the window in within the frame of wood. They are submerged beneath a bead or glazing putty that hardens to solid wedge that holds the wood frame firmly in position and conceals the edges.

After removal of the old pane clean the frame and the wood. Scrape away any paint and sand down the rabbet grooves, where the glazing points were. Sand them down to bare wooden surfaces, allowing you to paint the frames with the same color. After the sanding process, apply a coat of flax oil on the wood that is not sanded down to extend the life of the frame.

Then, you need to 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 seasons of change. Take these measurements to your local hardware or home improvement store, and they will have 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 Replace Window pane air from leaking into the frame and causing fogging.
