Glass Window Repair

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

Wearing protective clothing, cut off the metal glazing points and all glazing putty using an utility knife. A heat gun may help soften the old glue and make it easier to remove.

Replacement

When a window's pane breaks, it could be tempting to try and repair the glass instead of replace it. It is cheaper to replace a window and it can also help you to avoid other issues in the efficiency of your home. Take a look at the type of glass that is broken to determine if it's a temporary fix, or if a more permanent solution is needed.

To fix a damaged window, take off the frame or sash, and place it on the work surface. While wearing eye protection, carefully move the frame and remove any remaining shards in the window pane. Utilize a utility blade to scrape off the glazing compound, and the glazing points that hold the window in place. Keep an eye on the components and their location so they can be reinstalled.

Once the frame and sash are removed, you can begin preparing to install the new glass repair. Be sure to check that the opening of the frame is the right size for your replacement window. To allow for the expansion of the frame and glass and contraction, measure both directions across the opening and subtract 1/8 inch. Then, buy double-strength glass cut to these precise dimensions. It is also recommended to purchase enough new glazier's clips or glazier's points to be positioned every 6 inches around the window pane.

Based on the window's warranty, this may be covered by the manufacturer in which case you must contact the company to file a claim. After the new glass has been installed, it should be bedded in with a thin coating of glazier's compound. After the compound has dried it is possible to paint the frame to match.

If you have a crack that is more than an inch, scoring the crack with the edge of a blade just over the crack can help to stop it from spreading further. This method isn't foolproof, but it will slow down the progression of the cracked until you are able to take permanent measures.

Repair

Professional window installers know how to deal with a variety of glass types, and they have the tools needed to complete a proper job. They are able to dispose of waste properly, so they are less likely than others to leave behind scraps that could harm family members or pets. They're also familiar with various types of windows, and they may be aware of issues that aren't obvious to a homeowner who isn't experienced.

Wear safety goggles and gloves prior to beginning repair work on cracked glass. Even a small break can cause shards to fly off, which could pose a risk to anyone in or around the home. It is important to determine what caused the crack, so that you will help prevent any future problems.

Begin by creating a two-part epoxy mixture. They are typically a 50/50 mix of resin and hardener, and they must be quickly mixed. Once the mixture is done, apply it to the glass crack and allow it to dry. It should only take some minutes, but you need to be quick because the mixture is very thick and dries quickly.

After the epoxy has dried, you can remove any excess using a putty knife. You'll need to clean the cracks in the glass. If you do not clean the area properly the debris could cause further damage to the glass. After cleaning the glass with a putty blade, use it to smooth the compound along the edge of the window repair near, and then align it with the frame of wood.

To make a more durable option, consider using a plastic cover. A heavy-duty trash bag or tarp is the best option, company but you can also apply masking tape to the glass. This will prevent the crack from spreading, and will also keep wind, water and bugs out.

You can make a temporary fix when you are unable access the window in an efficient manner. Simply apply a small amount of the substance around the outside edge of the damaged pane. It won't completely fill the gap between the frame and glass, but it will keep the break in place while you repair it.

Repainting

If your glass windows are old, you may need to paint them. This is a low-cost alternative to replacing your windows and will provide your home with a new appearance. Before painting, ensure that the surface is clean. Use soap or rubbing alcohol and water to wash away oil smudges and other residues that could prevent paint from adhering. Wear rubber gloves when working on glass surfaces to prevent the transfer of oils from your hands onto the glass. In the end it is recommended to apply several thin coats of paint instead of a single thick layer. This will make the paint last longer and make your windows appear smooth and even.

If you're planning to paint your glass windows, make sure you have all the right tools nearby. You'll need a brush, sponge, painter's adhesive, a ruler, toothpicks, and other tools, such as a rag or paper towel. It is also recommended to have the paint and brushes you'll need to complete the project. Follow the manufacturer's instructions. Have patience as it can take some time for the paint to fully dry.

If you are using solvent-based paint, also ensure that the space where you work is well-ventilated. This will help to reduce the risk of breathing toxic chemicals, and also the paint will dry faster. 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 to painting. Clean the glass window thoroughly using soap and warm water. You can then apply rubbing alcohol to wash off any grease or oil that could hinder paint's adhesion. Make sure the windows are completely dry before you start coating them.

If you have energy-efficient double pane windows on your windows, it might be possible to file an insurance claim for repair or replacement with the window company or the dealer who sold the windows. This is especially true if you have experienced multiple problems with condensation or broken glass while the windows are still covered by warranty.

Sealing

There are a variety of options to address the issue, regardless of whether you have an older double-pane glass with cracks in the seal, or if you own an insulation unit (IGU) that has experienced fogging. It is the most expensive option to replace both the insulation unit and the frame. However, it may be necessary in cases where fog or condensation is causing energy losses. Other options include replacing the IGU by a single pane, or repairing glass the IGU that is in place by drilling a hole in its bottom and filling it with an anti-fogging agent.

You can also seal the gap between the window frame and the sill or threshold by using a felt strip, vinyl v-strip, or a door sweep. Felt can be stapled, glued or nailed into place but is not a great protection against moisture. Vinyl v-strip weather stripping is durable and easy to put in, but it can be costly and is generally used for areas that are subject to high abrasion. Door sweeps are able to be easily nailed in place and are inexpensive. However, they offer only a small amount of protection between the threshold and the air.

To repair a cracked window seal, first use a putty knife to take off the old caulk. Wearing protective eyewear and gloves, carefully pry out the glazing points -- small fasteners that hold the glass in the frame's recess using sharp edges and pointed ends. After removing the glazing points, clean the grooves and sand the wood smooth. Wipe away any sanding residue, then seal the bare wood using a linseed oil-based paint or clear wood sealer.

Traditional glazing putty is applied using the help of a putty blade or caulking gun. However, a knife provides a better application that is more precise and provides a stronger seal. Make sure you choose a putty made specifically for glass windows, since it will be more adhesive and long-lasting.

Apply a thin layer of putty on the inside of the frame where it meets with the glass. Slide the window into the frame so that the scribed line on glass aligns with edge of frame. Apply pressure to the glass to compress the putty and glass into a tight seal. Smooth the compound with fingers that are gloved and clean up any caulk that was applied incorrectly or errant drips before it dries.
