Then, use a knife to cut off the glazing compound and glazing points that help to hold the glass in the position. Keep an eye on the components and where they are so they can be reinstalled.
Once the frame and sash are removed then you can begin the process of preparing to install the new glass. Before doing this make sure that the opening in the frame is properly designed for the replacement window. Take measurements 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 a good idea also to purchase enough glazier's clips, or points to place them every 6 inches around each window pane.
Depending on the warranty of the window it could be covered by the manufacturer and in this case, you need to contact the company to file a claim.

Start by making a two-part epoxy mixture. They are typically 50/50 mixture of resin and hardener, and they must be mixed quickly. When the mixture is done, apply it to the crack in the glass and let it dry. It will take just some minutes but it's important to get it done quickly as the mixture is very thick and quick drying.
After the epoxy has dried, you can get rid of any excess with a putty knife. After that, you'll need clean the area around the cracked glass.

Use a putty blade to smooth out the compound around the edge of the window and match it with the frame of wood.
If you want a more durable solution think about using a plastic covering. A trash bag that is heavy-duty or tarp is the best option, but you can also use masking tape to cover the glass. This will prevent the crack from spreading and will also keep water, wind and bugs out.
You can make an interim solution when you are unable get to the window in time. Apply a small amount of silicone sealant around the edge of the damaged glass. It won't completely seal the gap between the glass and the frame completely, but it will hold the broken piece in place until you are able to fix it.
Repainting
If your windows with glass are old, you might consider repainting them. This is a low-cost alternative to replace your windows and will give your home a fresh look. Make sure that the surface is clean prior to painting. Use rubbing alcohol or soap and water to get rid of oil smudges, and other residues that could prevent paint from adhering. Wear rubber gloves when working on glass to avoid transferring your own oils onto the surface of the window. Apply several thin coats instead of a single thick one. This will make the paint last longer and will keep your windows looking smooth and even.
If you're planning on repainting your glass windows, make sure you have all the right tools in your arsenal. You'll need either a brush or sponge painter's tap, a ruler and toothpicks. You'll need the paints and brushes that you will be using in your kit. Follow the instructions of the manufacturer. Be patient, as it may take some time for the paint to completely dry.
If you're using solvent-based paints, you must also ensure that the room in which you work is well ventilated. This will help to reduce the risk of breathing toxic chemicals, and the paint will dry more quickly. Also, make sure you wear a mask that is protective for any spray paints you use.
You'll need to wash the glass window thoroughly using warm water and soap before you paint it. Clean the glass window thoroughly with soap and warm water. Then, apply rubbing alcohol to wash off any oil or grease that could hinder paint's adhesion. Make sure that the windows are completely dried before you begin to paint them.
If your glass windows are energy-efficient dual pane windows, you may be eligible to make a claim with the window manufacturer or dealer who sold them to cover any repair or replacement costs. This is particularly true if the windows are still under warranty and you've had numerous problems with condensation or broken glass.
Sealing
There are several ways to fix the problem, whether you have an old double-pane glass with cracks in the seal or if you have an insulation unit (IGU) that has experienced fogging. 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 it by drilling a small hole through the bottom of the unit, and then filling the solution with anti-fog.
You can also fill in the gap between windows and a threshold or sill by with a felt strip or vinyl v-strip. Felt is inexpensive and can be glued, nailed, or stapled into place, but it does not offer much protection against moisture. Vinyl v-strip is easy to put up and is durable however it can be expensive. It is usually reserved for areas that are exposed to abrasions that are high. Door sweeps are easy to nail in place and are cheap. However, they provide very little or no protection between the threshold and the air.
To repair a damaged window seal, use a putty blade to remove the old caulk. Wearing gloves and eye protection, pry out the glazing point -- small fasteners with sharp pointed tips that secure the glass to the frame's recess. After removing the glazing points, scrub the grooves and sand the wood smooth. Clean any sanding dust and then seal the unfinished wood surface using a linseed oil-based paint or clear sealer.
Traditional glazing putty is applied using a putty knife or caulking gun, but using a knife allows for a more efficient precision and precise application. It also provides a stronger seal. Choose a putty that is specifically designed for glass as it is more durable and adhere better.
Apply a thin layer of glue on the inside of the frame where it meets with the glass. Slide the window into the frame so that scribed line on glass aligns with edge of frame. Apply pressure to the glass to force the putty and glass to form an elongated seal. Smooth the compound using an ungloved finger, and wipe away any caulk that is applied incorrectly or spills that are not properly wiped away prior to drying.
