Glass Window Repair
Professional window repairmen can maneuver large glass panes from a height above the ground. They work in extreme conditions and follow strict safety guidelines.
While wearing protective clothing remove all glaze putty and glazing points using a 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. It is cheaper to replace a window and it can also help you prevent other problems in your home's efficiency. Consider the kind of glass damaged to determine whether it's a temporary fix, or if a permanent solution is required.
The first step to repair damaged windows is to remove the sash, or frame, and lay it flat on a work table. Wearing eye protection, gently move the window's frame and pull out any remaining shards. Then, use a knife to remove the glazing compound and glazing points that hold the glass in the position. Keep the track of the components and where they are to ensure they are reinstalled.
After you have 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 the proper size for the replacement window. Measure both ways across the opening, then subtract 1/8 inch from each measurement to allow 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 also to purchase enough glazier's clips, or points to be installed every 6 inches around each window pane.
Depending on the warranty of the window it could be covered by the manufacturer and in this case, you need to contact them to make an claim. After the new glass has been installed, it is important to cover it with a thin layer of glaziers compound. After drying the compound then you can paint it to match the rest of the frame.
If your crack is more than an inch in length, you can prevent it from spreading by slicing an arc that is just a little beyond the crack. This trick won't be infallible, but it will slow the development of the crack down to a manageable amount until you are able to take more permanent measures.
Repair
Professional window installers know how to handle a variety of glass types, and they have the tools necessary to do the job correctly. They are able to dispose of waste in a safe manner and are therefore less likely than others to leave behind a mess that could inflict harm on family pets or members of the family. They're also accustomed to working with different types of windows and may be capable of identifying issues that aren't apparent to the uninitiated homeowner.
Wear safety glasses and gloves prior to beginning the process of repairing damaged glass. A minor crack could cause shards of glass to fly away, creating a risk for anyone in or around the home. It's also important to determine what caused the crack in the first place, so that it can help prevent future problems.
Make a two-part mixture of epoxy. They usually consist of made up of a 50/50 mix of hardener and resin. They must be mixed quickly. Once the mixture is ready, apply it to the glass crack and let it dry. It should take only about a minute however it is important to work quickly since the mixture is extremely thick and quick drying.
After the epoxy has dried, you can remove any excess with a knife. Then, you'll have to clean the area around the cracked glass. If you don't do it properly, the residue can cause further damage to the glass. Make window repairs of a putty knife to smooth the compound around the window's edge and then match it to the frame made of wood.
If you want a more durable solution you can consider using a plastic cover. A trash bag that is heavy-duty or tarp is ideal, but you can also apply masking tape to the glass. This will prevent the crack from expanding, and will also block out water, wind, bugs, and debris.
You can make a temporary fix in the event that you are unable to reach the window in a timely manner. Simply place a tiny amount of the substance around the outside edge of the damaged pane. It won't completely fill the gap between glass and frame, but it will keep the broken piece in place while you repair it.
Repainting
If your windows with glass are old, you may need to paint them. This is a cost-effective alternative to replace your windows and will give your home a fresh look. Before painting, ensure that the surface is clean. Use soap or rubbing alcohol and water to remove oil smudges, and other residues which can prevent paint from adhering. Wear rubber gloves when working on glass surfaces to prevent the transfer of oils from your fingers onto the glass. Apply several thin coats instead of one thick coat. This will help the paint last longer, and will keep your windows looking smooth and even.
If you're planning on repainting your glass windows, make sure you have all the right tools in your arsenal. You'll need a sponge or brush painter's tap along with a ruler, toothpicks and a ruler. It is recommended to have the paints and brushes that you will be using in your kit. Follow the manufacturer's instructions. Be patient, as it may take a while for the paint to fully dry.
Also, ensure that the area you're working in is well ventilated, especially if you're using solvent-based paint. This will reduce the chance of breathing in harmful chemicals and allow the paint to dry quicker. It is also important to ensure you wear a mask that is protective for any spray paints that you use.
For older glass windows, you'll need to prepare the surface prior painting. Clean the glass window thoroughly with soap and warm water. You can then use rubbing alcohol to clean off any oil or grease that could hinder paint's adhesion. Make sure the windows are dry before you begin coating them.
If you have energy-efficient double-pane windows on your windows, it may be possible to file a claim for repair or replacement with the window company or dealer who sold them. This is particularly the case if you've experienced several issues with cracked glass or condensation even though the windows are covered by warranty.
Sealing
If you have double-pane windows with a damaged seal or more recent insulated glass units (IGUs) that have experienced defogging or fog, there are many options to fix the issue. It is the most expensive option to replace the IGU that is insulated as well as the frame. However, it may be necessary in cases where condensation or fog is causing energy loss. Other options include replacing the existing IGU with a single pane or fixing it by drilling a small hole through the bottom of the unit, and then filling the solution with anti-fog.
You can also close the gap between the window frame and the sill or threshold with a felt strip, vinyl v-strips, or door sweep. Felt is affordable and can be fixed by gluing, nailing, or stapled into place however it doesn't provide a lot of protection from moisture. Vinyl weather stripping that is v-strip is strong and easy to install however it can be costly and is generally reserved for areas exposed to abrasions that are high. Door sweeps are cheap and can be fixed into place however they provide virtually no barrier between the sill or threshold and air, dust, and debris.
To repair a damaged window seal, first employ a putty knife to scrape off the caulk. Wearing gloves and eye protection remove the glazing point -- tiny fasteners with sharp pointed tips that hold the glass into the frame's recess. After you have removed the glazing points, scrub the grooves and sand the wood to a smooth finish. Clean any sanding dust and then seal the unfinished wooden surface with a linseed-oil-based paint or clear sealer.
Traditional glazing putty is applied using either a putty knife or a caulking gun, however using a knife allows for a more efficient application that is more precise and creates a better seal. Choose a putty that is specifically designed for glass, as it will last longer and will adhere better.
Apply a thin layer of putty across the inside of the frame where it joins the glass. Slide the window into the frame so that the scribed line on the glass is aligned with the frame's edge. Apply pressure on the glass to press the putty and glass into an elongated seal. Smooth the compound using an ungloved finger, and wipe away any caulk that was applied incorrectly or drips that have escaped prior to drying.
