Glass Window Repair

Professional window repairmen work up above the ground, navigating huge panes of glass. They follow strict safety protocols and often work under 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 make it easier to remove.

Replacement

When a window pane is broken, it may be tempting to try and repair the glass rather than replace it. It is more cost-effective to replace a window, and it can also help to avoid other issues in the efficiency of your home. It is also important to consider the type of glass that's broken to determine if it is an interim fix or if you'll need to invest in an alternative that is more durable.

To repair a broken window, remove the frame or sash and place it on the floor. Wearing eye protection, gently wiggle the window's pane and then remove any remaining fragments. Then, use a utility knife to remove the glazing compound and points that help to hold the glass in place. Be sure to keep the track of the location of these components so that they can be reinstalled later.

After removing the frame and sash you can begin preparing to replace the glass. Before you begin, make sure that the opening in the frame is sized for your replacement window. To allow for expansion and contraction of the glass and frame and contraction to both directions, measure the opening and subtract 1/8 inch. Then, purchase double-strength glass that are cut to these exact dimensions. It is recommended also to purchase enough glazier's clips or points to be installed every 6 inches around each window pane.

If the manufacturer is accountable you should contact them and submit a claim. After the new glass has been erected it is essential to cover it with a thin layer glaziers compound. After the compound has dried and dry, you can paint it to match the rest of the frame.

If the crack is greater than an inch you can stop it from expanding by scoring an arc that is just a little beyond the crack. This method isn't completely foolproof, but it could slow the growth of the crack down to a manageable amount until you can take more permanent measures.

Repair

Professional window installers are equipped with the right tools and know how to handle different kinds of glass. They also understand the best practices for disposing of waste, and are less likely to leave waste that are left behind, which could injure family members or pets. They're also familiar with different types of windows and are aware of issues that aren't apparent to the uninitiated homeowner.

Wear safety glasses and gloves prior to beginning the process of repairing cracked glass. A minor crack could cause shards of glass to fly away, posing a danger to anyone who lives in or around the home. It's also crucial to determine the cause of the crack in the first place, so that it can help prevent future issues.

Begin by creating an epoxy mix that is two-part. They typically are made up of a 50/50 mix of hardener and resin. They must be mixed quickly. When the mixture is ready put it in the glass crack and leave it to dry. It should take only some minutes, but it is important to work quickly because the mixture is thick and dries very quickly.

Once the epoxy is dried, you can remove any excess with a knife. You'll need to scrub the cracked glass. If you don't do this properly, the residue can cause further damage to the glass. Make use of a putty knife to smooth the compound around the edge of your window and then match it to the wood frame.

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

You can create a temporary fix in the event that you are unable to access the window in a timely manner. Apply a small amount of silicone sealant to the edge of the broken glass. It won't completely seal the gap between frame and glass, but it will keep the crack in place while you fix it.

Repainting

If your windows with glass are old, you might want to repaint them. This is an affordable alternative to window replacement and it can give your home a new appearance. Before painting, make sure the surface is clean. Use soap or rubbing alcohol and water to remove oil smudges, and other traces of dirt that can hinder paint from adhering. You should also wear rubber gloves when working on glass to prevent the transfer of your own oils onto the window's surface. In the end it is recommended to apply several thin coats of paint instead of a single thick layer. This will allow the paint to last longer and keep your windows looking smooth and even.

If you're planning on repainting your glass windows, be sure you have the appropriate tools at hand. You'll need a brush, sponge, painter's adhesive, toothpicks, a ruler and other tools like paper towels or a rag. You should have the paints and brushes that you'll use in your kit. Follow the manufacturer's directions. Have patience as it can take some time for the paint to fully dry.

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

For older glass windows, it is necessary to prepare the surface prior to painting. Clean the glass window thoroughly with soap and warm water, then use rubbing alcohol to clean away any grease or oil that could affect the paint's adhesion. Make sure the windows are completely dry prior to coating them.

If your glass windows are energy efficient dual pane windows, you might be eligible to make a claim with the dealer or window company that sold them to cover any upvc repair or replacement costs. This is especially true if the windows are still under warranty and have experienced multiple problems with condensation or damaged glass.

Sealing

If you have double-pane windows with a cracked seal or newer insulated glass units (IGUs) that have experienced fogging and fogging, there are a variety of options to address the issue. The most expensive option is to replace the insulated unit and frame however it could be required if fog or condensation are causing energy loss. Other options include replacing the IGU with a single-pane, or fixing it by drilling a small hole into the bottom of the unit and filling the solution with anti-fog.

You can also close the gap between a window frame and a threshold or sill by using a felt strip, or vinyl V-strip. Felt is cheap and can be fixed by gluing, nailing, or stapled into place but it doesn't provide much protection from moisture. Vinyl v-strips are easy to install and durable however, it can be costly. It is generally reserved for areas exposed to abrasions that are high. Door sweeps are easy to nail in place and are inexpensive. However, they offer little or no protection between the threshold and the air.

To repair a broken window seal using a putty knife, you need to take off the caulk. Wearing gloves and eye protection take care to remove the glazing points -- tiny fasteners that fix the glass in the frame's recess using sharp and pointed ends. After taking out the glazing points, clean the grooves and sand the wood. Wipe off any sanding debris, then seal the bare wooden surface with a linseed-oil-based paint or clear sealer.

Traditional glazing putty can be applied with the help of a putty blade or caulking gun, however a knife provides a better precision and precise application. It also provides a stronger seal. Select a putty made specifically for glass windows, since it will have higher adhesion and a longer life.

Apply a thin layer of putty on the inside of the frame where it joins the glass. Slide the window into the frame, so that the cut line on the glass aligns with the edge of the frame. Apply pressure on 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 applied correctly before it dries.
