Glass Window Repair

Professional window repairmen work high off the ground, maneuvering huge panes of glass. They work under extreme weather conditions and adhere to strict safety guidelines.

While wearing protective clothing remove all glaze putty and glazing points using a knife. A heat gun can help to soften the old putty and make it easier to remove.

Replacement

When a window pane breaks, it can be tempting to try and repair the glass rather than replace it. It is more cost-effective to replace windows and it will also help to avoid other issues in your home's efficiency. Take a look at the type of broken glass to determine whether it's a temporary fix, or if a more permanent solution is required.

To repair a broken window, you must remove the sash or frame and place it flat on the work surface. Wearing eye protection, gently wiggle the window's frame and then remove any remaining fragments. Utilize a utility blade to remove the glazing compound, as well as the glazing points that secure the window. Keep track of the components and their location 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. Before you begin ensure that the opening in the frame is properly sized for your replacement window. Measure both sides of the opening, then subtract 1/8 inch from each measurement in order to leave room for expansion and contraction of the frame and glass. Then, buy double-strength glasses cut to these exact dimensions. It is also a good idea to purchase enough new glazier's clips or glazier's points to be positioned every 6 inches around the window pane.

If the manufacturer is responsible for this, you can call them and submit an claim. Once the new glass is installed, it needs to be covered with a thin coating of the compound used by glaziers. After drying the compound and dry, you can paint it to match the rest of the frame.

If your crack is longer than an inch you can stop it from expanding by scoring an arc that is just a little beyond the crack. This trick is not foolproof however it can slow the growth of the cracked until you are able to take permanent measures.

Repair

Professional window contractors are trained to deal with a variety of glass and have the tools necessary to do an excellent job. They also know the best practices for disposing of waste, and are less likely to leave scraps behind, which could potentially hurt pets or family members. They're also accustomed to working with different types of windows and could be able to spot issues that a home owner with no experience might not see.

Before beginning the process of repairing damaged window glass, be sure to wear safety glasses and gloves. A small crack could cause glass shards to fly away and put anyone at risk within or around the home. It's important to determine what caused the crack, since this will help prevent any future issues.

Begin by creating an epoxy mixture that has two parts. They typically are composed of a 50/50 blend of resin and hardener and must be mixed quickly. After the mix has been made, apply it directly to the crack and let it dry. This should only take about a minute but it's important to do it quickly because the mixture is very dense and fast drying.

Once the epoxy is dried, you can remove any excess with a knife. You'll then need to clean the cracks in the glass. If you do not clean the area correctly, the debris could cause further damage to the glass. Once the glass is cleaned with a putty blade, use it to smooth the compound along the edges of the window and match it to the frame made of wood.

Consider using a plastic cover to make a more durable choice. You can cover the glass with masking tape or a sturdy trashbag. This will stop the crack from spreading, and will also keep water, wind and insects out.

You can come up with an interim fix when you are unable get to the window in a timely manner. Apply a small amount silicone sealant on the edges of the broken glass. It won't completely fill the gap between the frame and glass, but it will keep the break in place while you fix it.

Repainting

If your windows with glass are old, you might need to paint them. This is a low-cost alternative to replace windows and give your home a fresh appearance. Make sure that the surface is clean prior to painting. Wash the window with soap and pane water or use ruby alcohol to get rid of oil smudges and other residues which can hinder the paint from adhering. It is also recommended to wear rubber gloves when working on glass to avoid transferring your own oils onto the window's surface. Apply multiple thin coats instead of a single thick one. This will allow the paint to last longer and will keep your windows looking smooth and even.

Make sure you have the appropriate tools available in case you want to paint glass windows. You will need a sponge or brush painter's tap as well as a ruler and toothpicks. You should also have the brushes and paint you'll need to complete the project. Follow the manufacturer's directions. Be patient as it can take a while for the paint to fully dry.

It is also important to ensure that the room you're working in is ventilated when you're using solvent-based paint. This will reduce the chance of breathing in toxic chemicals and permit the paint to dry more quickly. It is also important to ensure you have a mask to protect yourself for any spray paints you use.

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 scrub away any grease or oil that might hinder the paint's adhesion. Make sure that the windows are dry prior to coating them.

If your glass windows are energy-efficient dual pane windows, then you might be in a position to file a claim with the window company or dealer that sold them to cover any repair or replacement costs. This is especially relevant if you've had several issues with broken glass or condensation even though the windows are covered by warranty.

Sealing

There are several ways to resolve the issue, whether you have an old double glazed window repairs-pane glass with a cracked seal, or if you have an insulated unit (IGU) that has experienced fogging. The most expensive option is to replace the insulated unit and frame, but it may be necessary if condensation or fog cause energy loss. Other options include replacing the IGU by a single pane, or repairing the IGU that is in place by drilling a hole through the bottom and filling it up with an anti-fogging agent.

You can also close the gap between windows and a threshold or sill using a felt strip, or vinyl v-strip. Felt is affordable and can be fixed by gluing, nailing, or stapled into place but it doesn't provide a lot of protection from moisture. Vinyl weather stripping that is v-strip is strong and simple to install however, it can be costly and is generally used for areas that are subject to high abrasion. Door sweeps can be easily nailed in place and are cheap. However, they provide only a small amount of protection between the threshold and the air.

To fix a cracked window seal first, use a putty knife to take off the old caulk. Wearing gloves and eye protection take out the glazing point -- small fasteners with sharp pointed tips that secure the glass into the frame's recess. After removing the glazing points, clean out the grooves and sand down the wood. Wipe away any sanding sludge and then seal the unfinished wooden surface with a linseed-oil-based paint or clear sealer.

Traditional glazing putty is applied using a putty knife or caulking gun. However, the knife is a better precision and precise application. It also will provide a better seal. Make sure you choose a putty made specifically for glass windows, as it will be more adhesive and long-lasting.

Apply a thin layer of putty along the inside edge of frame where it joins the glass. Slide the window into the frame, so that the scribed line on the glass lines up with the frame's edge. Apply pressure on the glass to compress the putty and glass to form a tight seal. Smooth the compound with fingers that are gloved, and wipe away any mistakenly applied caulk or spills that are not properly wiped away before it is dry.
