Replacement

It is tempting to fix the window glass instead of replacing it when a pane breaks. However, replacing windows is often more cost-effective, and can also assist in preventing other issues with your home's energy efficiency. Consider the type of glass that is broken to determine if it's a temporary fix or if a long-term solution is required.

The first step in repairing a broken window is to remove the sash, also known as the frame and place it flat on a table. Wearing eye protection, gently move around and pull out any remaining shards in the window pane. Use a utility blade to scrape off the glazing compound and the glazing points that hold the window in place. Make sure you keep track of the components and their locations to ensure that they can be reinstalled later.

After you've removed the frame and sash you can begin to prepare to replace the glass. Make sure you check the opening of the frame is the right size for the replacement window. Take measurements both ways across the opening, then subtract 1/8 inch from each measurement to allow space for expansion and contraction of the frame and glass. Afterwards, purchase double-strength glass cut to these exact measurements. It is also a good idea to purchase enough new glazier's glazier's pointing or clips to be placed every 6 inches around the window pane.

If the manufacturer is responsible, you can call them and make a claim. After the new glass has been installed it is essential to cover it with a thin layer of glaziers compound. Once the compound is dry, you can paint the frame to match.

If your crack is more than an inch in length, you can prevent it from expanding by slicing an arc that is just a little beyond the crack. This method isn't foolproof, but it can slow the growth of the crack to a manageable amount until you are able to take more permanent measures.

Wear safety glasses and gloves prior to beginning the process of repairing cracked glass. A small crack could cause glass shards to fly and pose a risk to anyone inside or around the house. It's important to determine what caused the crack, since this can prevent future problems.

Start by making an epoxy mix that is two-part. They are usually made up of a 50/50 mix of resin and hardener and must be mixed quickly. After the mixture is made, apply it directly to the crack and let it dry. It should take only some minutes however it is important to do it quickly because the mixture is very thick and quick drying.

After the epoxy has dried, you can remove excess epoxy with a putty blade. You'll need to clean around the cracked glass. If you don't do it correctly, the resulting residue could cause further damage to the glass. Use a putty blade smooth out the compound around the edge of the window and then match it to the frame made of wood.

For a more durable solution think about using a plastic covering. A heavy-duty trash bag or tarp is ideal, however you can also use masking tape to cover the glass. This will prevent the crack from growing and will also block out water, wind bugs, debris, and water.

If you're not able to get to the window quickly then you can apply silicone sealant to make an interim repair. Apply a small amount of silicone sealant around the edge of the broken glass. It won't fully seal the gap between the frame and glass however it will keep the break in place while you repair it.

Repainting

If your windows with glass are old, you might need to paint them. This is an affordable alternative to replacing windows and give your house a new look. Make sure the surface is clean prior to painting. Use soap or rubbing alcohol and water to remove oil smudges and other traces of dirt that can hinder paint from adhering. You should also wear rubber gloves while working on glass to prevent the transfer of your own oils onto the window's surface. In the end you should apply several thin coats of paint instead of a thick layer. This will help the paint last longer and will keep your windows looking smooth and even.

Make sure you have the right tools in your arsenal when you are planning to repaint glass windows. You'll need a sponge or brush painter's tap along with a ruler, toothpicks and a ruler. You'll need the paints and brushes that you will be using on hand. Be sure to follow the manufacturer's directions and be prepared with plenty of patience since it may take awhile for the paint to dry.

If you are using solvent-based paint, you should also ensure that the space in which you work is adequately ventilated. This will help to reduce the risk of inhaling toxic chemicals, and also the paint will dry faster. Also, make sure you have a mask to protect yourself for any spray paints you use.

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

If you have energy-efficient double pane windows on your windows, it may be possible to submit claims for repair or replacement with the window company or dealer that sold them. 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 an upgraded insulated unit (IGU) that has experienced defogging. The most costly option is to replace the frame and insulated unit, but it may be required if fog or condensation are causing energy loss. Other options include replacing the IGU with 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 solution.

You can also fill in the gap between the window frame and the threshold or sill with a felt strip, vinyl v-strips, or door sweep. Felt is cheap and can be fixed by gluing, nailing or stapled in place however it doesn't offer much protection against moisture. Vinyl weather stripping that is v-strip is strong and easy to install however, 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 very little or no protection between the threshold and the air.

To repair a damaged window seal first, use a putty blade to take off the old caulk. Wearing eye protection and gloves, pry out the glazing point, which are small fasteners with sharp pointed tips that secure the glass in the frame's recess. After you have removed the glazing points, clean the grooves and sand the wood until it is 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 the help of a putty blade or caulking gun, however a knife provides a better, more precise application and provides a stronger seal. Choose a putty that is specifically designed for glass windows as it will be more adhesive and long-lasting.

Apply a thin layer of putty across the inside of the frame where it joins the glass. Slide the window into frame so that the scribed line on glass lines up with the frame's edge. Apply pressure on the glass to compress the putty and glass into 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.
