Glass Window Repair

Professional window repairmen work from high above the ground, moving huge panes of glass. They adhere to strict safety guidelines and frequently work in extreme weather conditions.

Wearing protective clothing, remove the metal glazing points and the glazing putty by using a utility knife. A heat gun can help soften the old putty and accelerate the removal process.

Replacement

When a window pane is broken, it may be tempting to repair the glass instead of replace it. It is cheaper to replace a window, and it will also help avoid other issues that could affect your home's efficiency. Take a look at the kind of glass damaged to determine if it's a temporary fix, or if a more permanent solution is required.

To fix a damaged window, you must remove the frame or sash, and lay it flat on the floor. Wearing eye protection, gently move the window's pane and pull out any remaining fragments. Use a utility blade to scrape off the glazing compound, as well as the glazing points that secure the window. Keep an eye on the components and their locations to ensure that they can be replaced later.

Once the frame and sash are removed, you can begin preparing to install new glass. Make sure you check the opening of the frame is the proper size for your replacement upvc window repairs. Measure both sides of the opening, and then subtract 1/8 inch from each measurement to give space for expansion and contraction of the frame and glass. After that, you can purchase double-strength glasses cut to these exact measurements. It is a good idea to purchase enough glazier's clips, or points to be installed 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 must contact them to make a claim. Once the new glass is installed, it should be bedded in with a thin layer of glazier's compound. After the compound has dried you can paint the frame to match.

If you have a crack that extends more than an inch, scoring an arc of a razor blade just beyond the crack could help prevent it from spreading any further. This technique isn't 100% completely foolproof, but it could slow the growth of the crack to a manageable level until you can take more permanent measures.

Repair

Professional window installers have the right tools and know how to handle various types of glass. They know how to dispose of waste safely and are therefore less likely than other contractors to leave behind pieces of glass that could harm family pets or family members. They are also experienced in working with various 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 prior to beginning the process of repairing cracked glass. A small crack can cause shards to fly, which could pose a risk to anyone who lives in or around the home. It's important to determine what caused the crack, so that you will help prevent any future problems.

Create a two-part mixture of epoxy. They are typically a 50/50 mix of resin and hardener, and they need to be mixed quickly. Once the mixture is prepared apply it to the crack in the glass and leave it to dry. It will take just a couple of minutes, but you need to work quickly because the mixture is thick and dries very quickly.

After the epoxy has dried, you can remove excess epoxy using a putty blade. You'll need to scrub the cracked glass. If you do not clean the area properly the residue could cause further damage to your glass. Make use of a putty knife to smooth the compound around the window's edge and match it to the wood frame.

Think about using a plastic lid for a more robust option. You can cover the glass with masking tape or a heavy-duty trashbag. This will prevent the crack from expanding and will also keep out water, wind bugs, debris, and water.

If you're unable to reach the window in a timely manner then you can apply silicone sealant to make a temporary repair. Apply a small amount of silicone sealant to the edges of the broken glass. It won't seal the gap between the frame and glass completely but it will hold the broken piece in place until you can repair it.

Repainting

Repainting old glass windows is a good idea. This is an affordable alternative to window replacement and it can give your home a new appearance. Make sure that the surface is clean before painting. Use soap or rubbing alcohol and water to wash away oil smudges, as well as 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. Finally, 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 smooth and even.

Make sure you have the right tools in your arsenal if you plan to repaint glass windows. You'll require a brush or sponge, painter's adhesive, a ruler, toothpicks, as well as a few other tools like a rag or paper towel. You'll need the paints and brushes that you'll use in your kit. Follow the manufacturer's directions. Be patient as it can take a while for the paint to completely dry.

It is also important to ensure that the area you're working in is well ventilated, especially if you're using solvent-based paint. This will lower the risk of breathing in toxic chemicals and permit the paint to dry faster. Use a mask that is protective when using spray paints.

You'll need to wash the glass window thoroughly using soap and warm water before you paint it. Clean the glass thoroughly with soap and warm water, then use rubbing alcohol to clean away any grease or oil that could affect the adhesion of the paint. Make sure that the windows are completely dry prior to coating them.

If you have energy-efficient double pane windows on your windows, it may be possible to make an insurance claim for repair or replacement with the company that makes the windows or dealer who sold the windows. This is particularly true if the windows are still under warranty and have experienced numerous problems with condensation or damaged glass.

Sealing

If you have double-pane windows that have 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 necessary if condensation or fog are causing energy loss. Other alternatives include replacing the current IGU with a single-pane, or repair it by drilling a small hole through the bottom of the unit and filling the solution with anti-fog.

You can also seal the gap between the window frame and the sill or threshold by using a felt strip, vinyl v-strips, or door sweep. Felt can be stapled, glued, or placed in place, but does not offer much protection against moisture. Vinyl v-strip weather stripping is durable and simple to install however it is costly and is usually used for areas that are subject to high abrasion. Door sweeps are cheap and can be nailed into place, but they create very little or no protection between the threshold or sill and dust, air and other debris.

To repair a damaged window seal first, you must use a putty knife to scrape off the caulk. Wearing eye protection and gloves remove the glazing point -- tiny fasteners with sharp pointed tips that secure the glass into the recess of the frame. After you have removed the glazing points, scrub the grooves and sand the wood smooth. Wipe away any sanding residue, then seal the bare wood with a linseed oil-based paint or clear wood sealer.

Traditional glazing putty can be applied with either a putty knife or a caulking gun, but using a knife allows for a more efficient precision and precise application. It also provides a stronger seal. Choose a putty specifically for glass as it will be more durable and stick better.

Apply a thin layer of glue across the inside of the frame where it meets with the glass. Slide the window into the frame so that the cut line on the glass lines up with the frame's edge. Apply pressure on the glass to press the putty and create a tight seal. Smooth the compound with a gloved finger, and wipe away any caulk that is applied incorrectly or drips that have escaped before it is dry.
