Glass Window Repair
Professional window repairmen are able to maneuver large panes of tempered glass from a height above the ground. They follow strict safety protocols and are often working in harsh weather conditions.
Wearing protective clothing, cut off the glazing points made of metal and all glazing putty using an utility knife. A heat gun can soften the old putty and make it easier to remove.
Replacement
When a window's pane breaks, it could be tempting to repair the glass instead of replace it. However, replacing a window is often more cost-effective and can assist in preventing other issues in your home's energy efficiency. You should also consider the kind of glass that is damaged to determine if it is a temporary fix or if you will need to invest in an option that is more permanent.
The first step in fixing damaged windows is to remove the frame, or sash and lay it flat on a table. While wearing eye protection, gently wiggle and pull out any remaining shards within the window. Then, use a utility knife to peel off the glazing compound as well as the glazing points that keep the glass in place. Keep track of the components and their location so they can be reinstalled.
After you have removed the frame and sash you can begin preparing to replace the glass. Before you do so make sure that the opening in the frame is properly designed for the replacement window. Measure both ways across the opening, then subtract 1/8 inch from each measurement to give the expansion and contraction of the frame and glass. Then, buy double-strength glasses that are cut to these exact dimensions. It is recommended also to purchase enough glazier's clips, or points to install every 6 inches around each window pane.
If the manufacturer is responsible then you should call them and file an claim. After the new glass has been put in place it is essential to cover it with a thin layer glaziers compound. After drying the compound then you can paint it to match the rest of the frame.
If you have a crack that extends more than an inch, scoring an arc of the edge of a blade just over the crack will help stop it from spreading further. This method isn't foolproof, but it can slow the development of the crack until you can take more permanent measures.
Repair

A small crack could cause glass shards to fly and pose a risk to anyone within or around the home. It's also important to figure out what caused the crack in the first place, since it could help avoid future issues.
Make a two-part mix of epoxy. They are usually composed of a 50/50 blend of resin and hardener and must be mixed quickly. Once the mixture is ready put it in the crack in the glass and let it dry. It will take just a few minutes, but it's essential to get it done quickly as the mixture is very dense and fast-drying.
Once the epoxy has dried, you can get rid of excess epoxy using a putty blade. You'll then need to clean the cracks in the glass. If you don't clean it properly, the residue can cause further damage to the glass. Use a putty blade smooth the compound around the window's edge and then match it to the frame of wood.
Think about using a plastic lid for a more durable option. A heavy-duty trash bag or tarp is the best option, but you can also use masking tape to cover the glass. This will stop the crack from spreading, and will also keep wind, water and bugs out.
If you're unable to reach the window in a timely manner, you can use silicone sealant to make temporary repairs. Apply window repairs Grays to the edge of the damaged glass. It won't close the gap between the frame and the glass completely however it will keep the break in place until you are able to repair it.
Repainting
If your glass windows are old, you might consider repainting them. This is a cost-effective alternative to replacing windows, and can give your home a fresh new look. Make sure the window is clean before painting. Clean the window with soap and water or use rubbing alcohol to remove oil smudges and other traces that can prevent the paint from adhering. Wear rubber gloves when working on glass to prevent the transfer of your own oils onto the surface of the window. Apply several thin coats rather than a single thick one. This will help the paint last longer, and will keep your windows looking smooth and even.
If you're planning to repaint your glass windows, make sure you have all the right tools nearby. You'll need a brush or sponge, painter's tape a ruler, toothpicks, and a few other tools like a rag or paper towel. You should have the paints and brushes that you'll use in your kit. Follow the manufacturer's instructions. Be patient, as it may take some time for the paint to fully 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 breathing into toxic chemicals and permit the paint to dry more quickly. Use a mask that is protective when using spray paints.
For older glass windows, you'll need to prepare the surface prior to painting. Clean the glass window thoroughly with soap and warm water. Then, use rubbing alcohol to scrub off any grease or oil that could affect the paint's adhesion. Make sure the windows are completely dry before you start coating them.
If your glass windows are energy efficient dual pane windows, you may be able to submit a claim to the dealer or window company who sold them to cover any repair or replacement costs. This is particularly the case if you've experienced multiple problems with cracked glass or condensation while the windows are still covered under warranty.
Sealing
Whether you have old double-pane windows that have a broken seal or a newer version of insulated glass units (IGUs) that have experienced defogging, there are several methods for fixing the problem. It is the most expensive option to replace both the insulated unit as well as the frame. However, it could be necessary if condensation or fog is causing energy loss. Other alternatives include replacing the current IGU with a single pane or repair it by drilling a small hole into the bottom of the unit, and then filling the solution with anti-fog.
You can also fill in the gap between a window frame and a sill or threshold using a felt strip or vinyl v-strip. Felt is inexpensive and can be glued, nailed or stapled to the frame however it doesn't provide much protection from moisture. Vinyl weather stripping that is v-strip is strong and easy to install, but it is costly and is usually reserved for areas exposed to high abrasion. Door sweeps are able to be easily nailed to the floor and are affordable. However, they offer 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 scrape off the caulk. Wearing gloves and eye protection, pry out the glazing point -- tiny fasteners with sharp pointed tips that hold the glass to the frame's recess. After removing the glazing points, scrub the grooves and sand the wood smooth. Clean any sanding dust, then seal the bare wood surface using a linseed oil-based paint or clear sealer.
A putty or caulking knife can be used to apply the traditional glazing putty, however a knife will provide a more precise application, and a stronger seal. Select a putty made specifically for glass windows, as it has better adhesion and long-lasting.
Apply a small amount the putty on the inside edge of the frame, where it meets the glass. Slide the window into the frame so that the scribed line on the glass aligns with the frame's edge. Apply pressure on the glass to press the putty and glass into an elongated seal. Smooth the compound with fingers that are gloved and clean up any caulk that was applied incorrectly or errant drips prior to drying.
