Glass Window Repair

Professional window repairmen can maneuver large panes of tempered glass from a height higher than the ground. They follow strict safety protocols and frequently work in extreme weather conditions.

The first step to repair damaged windows is to take off the sash, also known as the frame and place it flat on a work table. Wearing eye protection, gently move the window pane and remove any remaining fragments. Utilize a utility knife to cut off the glazing compound, and the glazing points that hold the window in place. Keep track of the components and their locations so they can be reinstalled.

After you've removed the frame and sash you can begin to prepare to replace the glass. Be sure to check that the opening of the frame is of the correct size for the replacement window. Measure both ways across the opening, then subtract 1/8 inch from each measurement to give room for expansion and contraction of the frame and glass. After that, you can purchase double-strength glasses cut to these exact measurements. It is recommended to purchase enough glazier's clips or points to install every 6 inches around the window pane.

Based on the window's warranty the window may be covered by the manufacturer in which case you need to contact them to file a claim. Once the new glass has been installed, it needs to be sprayed with a thin layer of glazier's compound. After drying the compound and dry, you can paint it to match the frame of the window.

If you have a crack that extends more than an inch, cutting an arc of a razor blade just beyond the crack will help stop it from spreading further. This technique isn't 100% foolproof but it can slow the growth of the cracked until you are able to take permanent measures.

It is also crucial to figure out what caused the crack in the first place, so that it could help avoid future issues.

Start by making an epoxy mixture that has two parts. They typically are composed of a 50/50 blend of hardener and resin. They must be mixed quickly. When the mixture is prepared, apply it to the crack in the glass and let it dry. It will take just about a minute but it's important to do it quickly because the mixture is extremely thick and quick drying.

After the epoxy has dried, you can get rid of any excess with a knife. After that, you'll need clean the area around the broken glass. If you do not clean the area properly, the debris could cause further damage to the glass. Use a putty blade smooth the compound around the edge of your window and match it with the wood frame.

You could consider using a plastic cover for a more durable option. A trash bag that is heavy-duty or tarp is ideal, however you can also use masking tape to cover the glass. This will stop the crack from spreading and will also keep water, wind and bugs out.

If you're not able to reach the window in a timely manner then you can apply silicone sealant to create temporary repairs. Apply a small amount of silicone sealant to the edges of the broken glass. It won't completely seal the gap between frame and glass however it will keep the broken piece in place while you fix it.

Repainting

If your glass windows are old, you may need to paint them. This is an affordable alternative to replacing windows and can give your home a fresh new look. Before painting, ensure that the surface is clean. Clean the window using water and soap or rubbing alcohol to remove oil smudges and other residues which can hinder the paint from adhering. Wear rubber gloves when working on glass surfaces to avoid transferring oils from your hands onto the surface. In the end it is recommended to apply several thin coats of paint instead of a single thick layer. This will help the paint last longer and keep your windows looking smooth and even.

If you're planning on repainting your glass windows, be sure you have the proper tools in your arsenal. You'll need a brush, sponge, painter's tape a ruler, toothpicks, and a few other tools like paper towels or a rag. It is recommended to have the paints and brushes that you'll use in your kit. Follow the manufacturer's instructions. Be patient, as it may take some time for the paint to fully dry.

It is also important to ensure that the space you're working is ventilated when you're using solvent-based paint. This will help to reduce the chance of inhaling toxic chemicals, and also the paint will dry more quickly. Use a mask that is protective when using spray paints.

For older glass windows, you'll need to prepare the surface prior to painting. Clean the glass window thoroughly using soap and warm water. You can then use rubbing alcohol to scrub away any grease or oil that could affect the adhesion of the paint. Make sure the windows are completely dry before you start coating them.

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

Sealing

Whether you have old double-pane windows with damaged seal or more recent insulated glass units (IGUs) that have experienced defogging or fog, there are many options for fixing the problem. The most expensive 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 existing IGU with a single-pane or repair it by drilling a small hole into the bottom of the unit, and then filling the solution with anti-fog.

You can also seal up the gap between windows and a threshold or sill using a felt strip, or vinyl v-strip. Felt can be stapled, glued, or nailed into place but does not offer much protection against moisture. Vinyl v-strip is easy to put up and is durable however, it can be costly. It is usually reserved for areas exposed to abrasions that are high. Door sweeps are easy to nail in place and are cheap. However, they provide very little or no protection between the threshold and air.

To repair a broken window seal using a putty knife, you need to take off the caulk. Wearing gloves and eye protection remove the glazing point, which are small fasteners with sharp pointed tips that secure the glass to the recess of the frame. After taking out the glazing points, remove the grooves and sand down the wood. Clean any sanding dust, then seal the bare wood surface using a linseed oil-based paint or clear sealer.

A putty or caulking knife can be used to apply the traditional glazing putty. However, using a knife will give an easier application and a stronger seal. Choose a putty that is specifically designed for glass windows, as it will be more adhesive and a longer life.

Apply a thin layer of putty along the inside edge of frame where it meets with the glass. Slide the window into the frame, so that the drawn line on the glass is aligned with the frame's edge. Apply pressure on the glass to compress the putty into a tight seal. Smooth the compound with gloves and get rid of any caulk or drips that were not properly applied before it dries.
