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.

While wearing protective clothing remove all glazing putty and metal glazing points with a utility knife. A heat gun can help soften the old glue and speed up removal.

Replacement

When a window's pane breaks, it could be tempting to repair the glass instead of replace it. It is more cost-effective to replace a window, and it will also help 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 long-term solution is needed.

To fix a broken window repairs, you must remove the frame or sash, and lay it flat on your work surface. Wearing eye protection, gently move around and pull out any shards that remain in the window pane. Then, use a utility knife to peel off the glazing compound as well as the glazing points that help to hold the glass in the position. Keep track of the components and where they are so that they can be put back in place.

After you've removed the frame and sash you can start preparing to replace the glass. Make sure that the opening of the frame is the proper size for the 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, buy double-strength glass cut to these exact measurements. It is recommended to also purchase enough glazier's clips, or points to place them every 6 inches around the window pane.

Depending on the warranty of the window it could be covered by the manufacturer, in which case you need to contact them to make an claim. After the new glass has been installed, it must be sprayed with a thin layer of glazier's compound. Once the compound is dry, you can paint the frame to be a perfect match.

If the crack is greater than an inch in length you can stop it from expanding by slicing an arc that is just a little beyond the crack. This technique isn't 100% foolproof however it can slow the development of the crack until you are able to take permanent measures.

Repair

Professional window installers have the proper tools and know how to work with different types of glass. They also understand the best ways to dispose of garbage, which means they're less likely to leave waste behind, which could potentially hurt pets or family members. They're also accustomed to working with various types of windows and could be able spot problems that a home owner with no experience might not be able to notice.

Before you begin the process of repairing damaged window glass, make sure that you wear safety goggles and gloves. A small crack can cause shards to fly off, posing a danger to anyone who lives in or around the home. It's also crucial to determine what caused the crack in the first place, since it could help avoid future problems.

Start by making an epoxy mixture that has two parts. They typically are a 50/50 mixture of resin and hardener and must be mixed quickly. Once the mixture is prepared, apply it to the glass crack and let it dry. It should only take some minutes, but you must be quick because the mixture is thick and dries quickly.

Once the epoxy has dried, you can remove excess epoxy with a putty blade. You'll need to scrub the cracked glass. If you don't clean the area properly, the leftovers could cause further damage to the glass. Use a putty blade smooth the compound around the edge of the window and then match it to the wood frame.

Think about using a plastic lid to make a more durable choice. A heavy-duty trash bag or tarp is ideal, however you can also apply masking tape to the glass. This will stop the crack from spreading, and will also keep wind, water and insects out.

If you're not able to reach the window fast enough then you can apply silicone sealant to create a temporary repair. Apply a small amount silicone sealant to the edge of the broken glass. It won't completely seal the gap between frame and glass but it will help keep the break in place while you repair it.

Repainting

If your glass windows are old, you might consider repainting them. This is a cost-effective alternative to replacing your windows and can provide your home with a new look. Make sure that the surface is clean before painting. Clean the window using water and soap or ruby alcohol to eliminate oil smudges and other traces that can prevent the paint from adhering. You should also wear rubber gloves when working on glass to avoid the risk of transferring your own oils onto the window's surface. Also it is recommended to apply several thin coats of paint instead of a single thick layer. This will make the paint last longer and ensure that your windows appear smooth and even.

If you're planning to paint your glass windows, be sure you have the appropriate tools at hand. You'll require a sponge or brush, painter's tap along with a ruler, toothpicks and a ruler. You'll need the paints and brushes that you'll use on hand. Follow the manufacturer's instructions. Be patient, as it may take some time for the paint to completely dry.

If you are using solvent-based paints, you must also ensure that the room where you work is well ventilated. This will decrease the risk of breathing in toxic chemicals and permit the paint to dry quicker. Use a protective mask when using spray paints.

For older glass windows, you'll need to prepare the surface prior painting. Clean the glass thoroughly with soap and warm water. Then, use rubbing alcohol to clean off any oil or grease that could affect the adhesion of the paint. Make sure the windows are completely dry before you begin coating them.

If your glass windows are energy-efficient dual pane windows, you might be in a position to file a claim with the dealer or window company who sold them to cover any repair or replacement costs. This is particularly the case if you've experienced numerous issues with broken glass or condensation and the windows are covered by warranty.

Sealing

There are several ways to fix the problem regardless of whether you have an old double-pane window that has cracks in the seal, or if you own a newer insulation unit (IGU) that has experienced defogging. It is the most expensive option to replace the insulation unit and the frame. However, it may be required in situations where fog or condensation is creating energy losses. Other options include replacing the IGU with a single pane or repair it by drilling a small hole in the bottom of the unit and then filling the solution with anti-fog.

You can also fill in the gap between the window frame and the threshold or sill by with a felt strip or vinyl V-strip. Felt can be stapled, glued, or nailed into place but is not a great protection against moisture. Vinyl weather stripping that is v-strip is strong and simple to install however, it can be expensive and is typically used for areas that are subject to high abrasion. Door sweeps are cheap and can be nailed to the floor however they provide virtually no barrier between the sill or threshold and dust, air, and other debris.

To fix a damaged window seal, use a putty blade to take off the caulk. Wearing protective eyewear and gloves, carefully pry out the glazing points -- tiny fasteners that pin the glass in the frame's recess, with sharp, pointed ends. After removing the glazing points, clean the grooves, then sand the wood. Wipe away any sanding sludge then seal the wooden surface with a linseed-oil-based paint or clear sealer.

A putty or caulking knife can be used to apply the traditional glazing putty. However, the use of a knife allows for a more precise application, and a more secure seal. Select a putty made specifically for glass, since it is more durable and will adhere better.

Apply a small amount of the putty on the inside edge of the frame, where it meets the glass. Slide the window into the frame in a way that the scribed line on the glass aligns with the edge of the frame. Apply pressure on the glass to force the putty and glass to form a tight seal. Smooth the compound with an ungloved finger and then wipe off any mistakenly applied caulk or wooden spills that are not properly wiped away before it is dry.
