Glass Window Repair

Professional window repairmen work from high above the ground, navigating huge panes of glass. They follow strict safety protocols and are often working in harsh weather conditions.

Wearing protective clothing, remove all glazing putty and glazing points using a utility knife. A heat gun can help soften the old putty and speed up removal.

Replacement

When a window pane breaks, it can be tempting to try and repair the glass rather than replace it. It is cheaper to replace a window, and it will also help prevent other problems in the efficiency of your home. Consider the type of glass that is broken to determine if it's a temporary fix or if a permanent solution is needed.

To fix a broken window, remove the frame or sash and place it on your work surface. Wearing eye protection, gently move the window's pane and pull out any remaining fragments. Then, use a knife to cut off the glazing compound as well as the glazing points that keep the glass in place. Keep an eye on the components and their location so they can be reinstalled.

After you've removed the frame and sash, you can begin preparing to replace the glass. Make sure you check the opening of the frame is the proper size for the replacement window. To allow for the expansion of the frame and glass and contraction take measurements in both directions across the opening and subtract 1/8 inch. Then, purchase double-strength glass cut to these exact dimensions. It is a good idea to also purchase enough glazier's clips, or points to install every 6 inches around the window pane.

Depending on the window's warranty it could be covered by the manufacturer in which case you need to contact the company to file an claim. After the new glass has been installed it is essential to cover it with a thin layer of glaziers compound. After drying the compound and dry, you can paint it to match the rest of the frame.

If your crack is longer than an inch you can stop it from expanding by slicing an arc that is just a little beyond the crack. This technique isn't 100% infallible, but it will slow the development of the crack down to a manageable level until you are able to take more permanent measures.

Repair

Professional window contractors are trained to handle a variety of glass types, and they have the tools to do the job correctly. They are able to dispose of waste in a safe manner, so they are less likely than other people to leave behind pieces of glass that could inflict harm on family members or pets. They are also familiar with working with different types of windows, and may be able to spot issues that a novice home owner might not be able to notice.

Wear safety glasses and gloves before you begin the process of repairing cracked glass. A minor crack could cause shards to fly, posing a danger to anyone living in or around the home. It is also crucial to determine the cause of the crack in the first place, so that it can help prevent future problems.

Make a two-part mix of epoxy. They are usually made up of a 50/50 mix of resin and hardener and must be mixed quickly. When the mixture is ready put it in the crack in the glass and let it dry. It should only take a couple of minutes, but you need to work quickly because the mixture is very thick and will dry quickly.

Once the epoxy is dried, you can take off any excess with a knife. After that, you'll need clean the area around the cracked glass. If you do not clean the area correctly the residue could cause further damage to the glass. After cleaning the glass using a putty knife, you can use it to smooth the compound along the edges of the window, and then match it with the frame of wood.

Consider using a plastic cover for a more durable option. A trash bag that is heavy-duty or tarp is the best option, but you can also apply masking tape to the glass. This will prevent the crack from spreading and will also keep water, wind and insects out.

You can create a temporary fix in the event that you are unable to get to the window in an efficient manner. Simply apply a small amount of the substance around the outside of the damaged pane. It won't seal the gap between the frame and the glass completely however it will keep the fracture until you are able to repair it.

Repainting

If your glass windows are old, you may consider repainting them. This is a cost-effective alternative to window replacement and it can give your home a fresh new appearance. Before painting, ensure that the surface is clean. Use rubbing alcohol or soap and water to remove oil smudges, and other residues which can prevent paint from adhering. It is also recommended to wear rubber gloves when working on glass to avoid the risk of transferring your own oils onto the glass surface. Also you should apply several thin coats of paint instead of a single thick layer. This will help the paint last longer and ensure that your windows appear even and smooth.

If you're planning on repainting your glass windows, ensure that you have the appropriate tools nearby. You'll require a sponge or brush, painter's tap as well as a ruler and toothpicks. You should have the brushes and paints you'll use in your kit. Follow the manufacturer's instructions. Be patient because it could take a while for the paint to fully dry.

You should also make sure the room you're working in is well ventilated if you're using solvent-based paint. This will reduce the risk of inhaling toxic chemicals, and the paint will dry more quickly. Wear a mask to protect yourself when using spray paints.

For older glass windows, you'll need to prepare the surface prior to painting. Make use of soap and warm water to thoroughly clean the glass window. Then, use rubbing alcohol on any grease or oil remnants that may hinder the paint's adhesion. Make sure that the windows are dry before you start coating them.

If your glass windows are energy-efficient dual pane windows, you might be in a position to make a claim with the window company or dealer that sold them to pay any repair or replacement costs. This is especially relevant if you've had several issues with cracked glass or condensation even though the windows are covered under warranty.

Sealing

Whether you have old double-pane windows with a cracked seal or newer insulated glass units (IGUs) that have experienced defogging or fog, there are many options for fixing the problem. The most costly option is to replace the insulated unit and frame, but it may be required if fog or condensation are causing energy loss. Other options include replacing the IGU by a single pane, or repairing the IGU that is in place by drilling a hole through the bottom and filling it with an anti-fogging solution.

You can also seal the gap between the window frame and the sill or threshold with a felt strip, vinyl v-strip, or a door sweep. Felt can be stapled, glued or nailed into place but does not offer much protection against moisture. Vinyl weather stripping that is v-strip is strong and easy to put in however, it is costly and is typically used for areas that are subject to high abrasion. Door sweeps are easy to nail to the floor and are affordable. However, they provide very 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 protective eyewear and gloves take care to remove the glazing points, which are tiny fasteners that hold the glass to the frame's recess with sharp and pointed edges. After taking out the glazing points, remove the grooves and sand the wood. Wipe off any sanding traces Then, seal the bare wood using a linseed oil-based paint or clear wood sealer.

Traditional glazing putty is applied using either a putty knife or a caulking gun. However, using a knife allows for a more efficient precision and precise application. It also creates a better seal. Choose a putty that is specifically designed for glass, since it is more durable and stick better.

Apply a small amount of the putty to the inside edge of the frame, where it meets the glass. Slide the window into the frame, so that the drawn line on the glass is aligned with the edge of the frame. Apply pressure to the glass in order to press the putty to form a tight seal. Smooth the compound with gloves and then remove any caulk or drips that were not applied correctly before it dries.
