Glass Window Repair

Professional window repairmen are able to move large glass panes from a height above the ground. They follow strict safety protocols and often work under harsh weather conditions.

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 accelerate the removal process.

Replacement

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

The first step in repairing a broken window is to remove the sash, or frame and lay it flat on a work table. Wearing eye protection, gently wiggle the window's frame and then remove any remaining fragments. Use a utility blade to cut off the glazing compound, and the glazing points that secure the window. Keep track of the components and their location to ensure they are reinstalled.

After the frame and sash are removed and the frame is removed, you can begin preparation to install new glass. Be sure to check that the opening of the frame is the proper size for the replacement window. Take measurements both ways across the opening, then subtract 1/8 inch from each measurement to allow the expansion and contraction of the frame and glass. Afterwards, purchase double glazed window repairs-strength glass cut to these exact dimensions. It is a good idea also to purchase enough glazier's clips, or points to place them every 6 inches around the window pane.

Based on the window's warranty, this may 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 must be covered with a thin coating of glazier's compound. Once the compound is dry it is possible to paint the frame to match.

If you have a crack that extends more than an inch, cutting an arc of the edge of a blade just over the crack can help to prevent it from spreading any further. This trick is not foolproof however it can slow the development of the crack until you are able to take permanent measures.

Repair

A minor crack could cause shards of glass to fly away, which could pose a risk to anyone living in or around the home. It's important to determine the cause of the crack, since this will help prevent any future problems.

Begin by creating an epoxy mix that is two-part. They are typically 50/50 mix of hardener and resin, and must be mixed quickly. After the mixture is prepared then apply it directly to the crack and let it dry. It should only take about a few minutes, but you need to be quick as the mixture is extremely thick and will dry quickly.

After the epoxy has dried, you can take off any excess with a putty knife. You'll need to clean the cracks in the glass. If you do not clean the area correctly the debris could cause further damage to your glass. After cleaning the glass using a putty knife, you can use it to smooth the compound along the edge of the window and to match it to the frame of wood.

For a more durable solution you can consider using a plastic covering. 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 wind, water and insects out.

You can create a temporary fix when you are unable access the window in a timely manner. Simply place a tiny amount of the stuff around the outside edge of the damaged pane. It won't completely seal the gap between the glass and the frame completely but it will hold the break in place until you are able to fix it.

Repainting

If your windows with glass are old, you might need to paint them. This is a low-cost alternative to replacing your windows and can give your home a fresh look. Before painting, make sure the surface is clean. Use soap or rubbing alcohol and water to get rid of oil smudges and other residues which can prevent paint from adhering. Wear rubber gloves when working on glass to prevent the transfer of your own oils onto the glass surface. Apply multiple thin coats instead of just one large coat. This will help the paint last longer and will keep your windows looking even and smooth.

If you're planning on repainting your glass windows, ensure that you have the proper tools nearby. You'll require a brush or sponge, painter's adhesive, toothpicks, a ruler as well as a few other tools such as a rag or paper towel. You should have the brushes and paints you'll use in your kit. Make sure you adhere to the manufacturer's guidelines and be prepared with plenty of patience as it can take awhile for the paint to dry.

It is also important to ensure that the room you're working in is well ventilated, especially if you're using solvent-based paint. This will decrease the risk 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 before painting. Clean the glass window thoroughly using soap and warm water. Then, use rubbing alcohol to clean off any grease or oil that could hinder paint's adhesion. Be sure that the windows are dry before you begin painting 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 window company or dealer that sold them. This is especially true if your windows are still under warranty and you've experienced multiple problems with condensation or broken glass.

Sealing

There are many ways to address the issue, whether you have an old double-pane glass with a cracked seal, or if you have an insulated unit (IGU) that has experienced fogging. It is the most expensive option to replace the insulated unit as well as the frame. However, it might be required in situations where condensation or fog is causing energy losses. Other alternatives include replacing the current IGU with a single-pane, or repairing it by drilling a small hole into the bottom of the unit and then filling the solution with anti-fog.

You can also close the gap between windows and a sill or threshold with a felt strip or vinyl v-strip. Felt is affordable and near can be fixed by gluing, nailing or stapled in place however it doesn't offer much protection against moisture. Vinyl v-strips are simple to install and durable however it can be expensive. It is typically used in areas that are exposed to abrasions that are high. Door sweeps can be easily nailed in place and are inexpensive. However, they provide very little or no protection between the threshold and the air.

To fix a cracked window seal first, you must employ a putty knife to take off the old caulk. Wearing gloves and eye protection, carefully pry out the glazing points -- small fasteners that pin the glass in the frame's recess using sharp, pointed ends. After getting rid of the glazing points remove the grooves, then sand the wood. Wipe off any sanding debris then seal the wood surface using 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 will provide a better seal. Choose a putty that is specifically designed for glass windows, since it will be more adhesive and durability.

Apply a small amount the putty on the inside edge of the frame where it touches the glass. Slide the window into the frame so 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 into an elongated seal. Smooth the compound using fingers that are gloved and then wipe off any caulk that was applied incorrectly or spills that are not properly wiped away before it is dry.
