Glass Window Repair

Professional window repairmen work high off the ground, maneuvering massive glass panes. They follow strict safety protocols and are often working in extreme weather conditions.

Wearing protective clothing, cut off the metal glazing points and the glazing putty by using a utility knife. A heat gun can to soften and eliminate the old putty.

Replacement

When a window's pane breaks, it can be tempting to repair the glass instead of replace it. However, replacing a window is often more cost-effective, and can also assist in preventing other issues that could affect your home's energy efficiency. Take a look at the type of broken glass to determine if it's a temporary fix, or if a permanent solution is needed.

To fix a damaged window, take off the frame or sash, and lay it flat on your work surface. While wearing eye protection, gently wiggle and pull out any remaining shards within the window. Then, use a knife to cut off the glazing compound as well as the glazing points that hold the glass in the position. Keep an eye on the components and where they are to ensure they are reinstalled.

Once the frame and sash have been removed and the frame is removed, you can begin preparation to install new glass. Be sure to check that the opening of the frame is the right size for the replacement window. Measure both sides of the opening, and then subtract 1/8 inch from each measurement in order to leave room for expansion and contraction of the frame and glass. After that, you can purchase double-strength glasses cut to these exact dimensions. It is recommended to purchase enough glazier's clips or points to install every 6 inches around each window pane.

If the manufacturer is responsible you should contact them and file an claim. After the new glass has been put in place, it is important to cover it with a thin layer of glaziers compound. Once the compound is dry you can paint the frame to be a perfect match.

If your crack is longer than an inch in length you can stop it from spreading by slicing an arc that is just a little beyond the crack. This technique isn't 100% foolproof but it can slow the progression of the cracked until you can take permanent measures.

Repair

Start by making a two-part epoxy mixture. These are usually 50/50 mixture of hardener and contractor resin, and they need to be mixed quickly. Once the mixture is prepared, apply it to the crack in the glass and allow it to dry. It will take just some minutes, but you must be quick because the mixture is very thick and drys very quickly.

After the epoxy has dried, you can get rid of any excess with a putty knife. You'll then need to clean the cracks in the glass. If you do not clean the area in a proper manner the residue could cause further damage to your glass. Make use of a putty knife to smooth the compound around the edge of the window and then match it to the frame made of wood.

For a more durable solution think about using a plastic covering. You can cover the glass using masking tape or a sturdy trash bag. This will prevent the crack from spreading and will also keep water, wind and insects out.

You can come up with an interim solution if you are unable to access the window in a timely manner. Simply run a bead of the material around the outside of the broken window. It won't close the gap between the frame and the glass completely, but it will hold the broken piece in place until you can fix it.

Repainting

Repainting your old glass windows is a great idea. This is a low-cost alternative to replacing your windows and can give your house a new appearance. Before painting, make sure the surface is clean. Wash the window with soap and water or use rubbing alcohol to remove oil smudges as well as other residues that can prevent the paint from adhering. Wear rubber gloves while working on glass to avoid transferring your own oils onto the window's surface. Also, you should apply several thin coats of paint instead of one thick layer. This will make the paint last longer, and will keep your windows looking smooth and even.

If you're planning to repaint your glass windows, ensure that you have the proper tools at hand. You will need either a brush or sponge as well as a painter's tamper along with a ruler, contractor toothpicks and a ruler.

Be patient, as it may take some time for the paint to completely dry.

If you're using solvent-based paints, you must also ensure that the space where you work is adequately ventilated. This will help to reduce the risk of inhaling toxic chemicals, and the paint will dry faster. Use a mask that is protective when using spray paints.

You'll need to wash the glass window thoroughly using soap and warm water prior to you paint it. Use warm water and soap to thoroughly clean the glass window.

This is especially true if your windows are still under warranty and you've experienced numerous problems with condensation or broken glass.

Sealing

There are many ways to resolve the issue regardless of regardless of whether you have an old double-pane window that has cracks in the seal or if you have an upgraded insulated unit (IGU) that has experienced defogging. It is the most expensive option to replace both the insulation unit and the frame. However, it might be required in situations where fog or condensation is creating energy losses. Other options include replacing the IGU with just one pane, or contractor repairing the existing IGU by drilling a hole in the bottom and filling it up with an anti-fogging product.

You can also close the gap between the window frame and the sill or threshold by using a felt strip vinyl v-strip, or a door sweep. Felt can be stapled, glued, or nailed into place but is not a great protection against moisture. Vinyl v-strip weather stripping is durable and simple to install however it can be expensive and is generally reserved for areas exposed to high abrasion. Door sweeps can be easily nailed in place and are cheap. However, they provide little or no protection between the threshold and air.

To repair a damaged window seal, use a putty blade to remove the old caulk. Wearing gloves and eye protection take out the glazing point -- small fasteners with sharp pointed tips that secure the glass into the frame's recess. After removing the glazing points, clean the grooves and sand the wood. Wipe off any sanding debris, then seal the bare wood surface using a linseed oil-based paint or clear sealer.

Traditional glazing putty can be applied with either a putty knife or a caulking gun. However, the knife is a better, more precise application and creates a better seal. Select a putty specifically designed for glass windows, since it will have higher adhesion and a longer life.

Apply a small amount the putty on the inside edge of the frame where it meets the glass. Slide the window into the frame so that the scribed line on glass aligns with the frame's edge. Apply pressure to the glass to force the putty and glass into an elongated seal. Smooth the compound with a gloved hand and remove any caulk or drips that were not properly applied before it has dried.
