Then, use a utility knife to peel off the glazing compound and points that hold the glass in place. Make sure you keep the track of the location of these components to ensure that they can be put back in place later.

After the frame and sash are removed and the frame is removed, you can begin preparation to install new glass. Before you do so ensure that the opening in the frame is properly size for the replacement window. To allow for frame and glass expansion and contraction to both directions, measure the opening and subtract 1/8 inch. Afterwards, purchase double-strength glass cut to these exact measurements. It is also an excellent idea to buy enough new glazier's clips or glazier's points to be installed every 6 inches around the window repairs pane.

If the manufacturer is responsible for this you should contact them and file an claim. After the new glass has been erected, it is important to cover it with a thin layer glaziers compound. After the compound has dried and dry, you can paint it to match the rest of the window frame.

If you have a crack that extends more than an inch, scoring an arc of a razor blade just beyond the crack could help stop it from spreading further. This method isn't infallible, but it will slow the growth of the crack down to a manageable size until you can take more permanent measures.

It is also crucial to figure out what caused the crack in the first place, as it can help prevent future problems.

Create a two-part mixture of epoxy. They are usually made up of a 50/50 mix of hardener and resin. They must be mixed quickly. After the mixture is made then apply it directly to the crack and allow it to dry. This should only take about a minute, but it's essential to work quickly since the mixture is very thick and fast-drying.

Once the epoxy has dried, you can remove excess epoxy using a putty blade. You'll need to clean around the cracked glass. If you don't clean the area in a proper manner the residue could cause further damage to the glass. Once the glass is cleaned using a putty knife, you can use it to smooth the compound along the edges of the window and match it with the frame of wood.

You could consider using a plastic cover for a more durable option. You can cover the glass using masking tape or a strong-duty trash bag. This will prevent the crack from growing and will also block out water, wind, bugs, and debris.

You can create an interim fix when you are unable reach the window in time. Apply a small amount silicone sealant around the edge of the damaged glass. It won't seal the gap between the frame and glass completely, but it will hold the broken piece in place until you can repair it.

Repainting

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 manufacturer or dealer that sold them. This is especially true if the windows are still under warranty and you've experienced several issues with condensation or broken glass.

Sealing

If you have double-pane windows with a damaged seal or more recent insulated glass units (IGUs) that have experienced fogging, there are several methods for fixing the problem. The most costly option is to replace the frame and insulated unit, but it may be required if fog or condensation cause energy loss. Other alternatives include replacing the current IGU with a single-pane or fixing it by drilling a small hole into the bottom of the unit and filling the solution with anti-fog.

You can also seal up the gap between windows and a threshold or sill with a felt strip or vinyl v-strip. Felt is inexpensive and can be fixed with glue, nailed or stapled in place however it doesn't provide a lot of protection from moisture. Vinyl weather stripping that is v-strip is strong and simple to install, but it is costly and is typically used for areas that are subject to high abrasion. Door sweeps can be easily nailed in place and are cheap. However, they provide very little or no protection between the threshold and air.

To repair a damaged window seal, use a putty blade to remove the old caulk. Wearing gloves and eye protection take care to remove the glazing points -- small fasteners that hold the glass in the frame's recess, with sharp edges and pointed edges. After removing the glazing points, scrub the grooves and sand the wood to a smooth finish. Wipe away any sanding residue Then, seal the bare wood using 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 the knife is a better application that is more precise and creates a better seal. Select a putty specifically designed for glass windows, since it will be more adhesive and a longer life.

Apply a thin bead of the putty on the inside edge of the frame, where it meets the glass. Slide the window into the frame so that scribed line on glass aligns with the frame's edge. Apply pressure on the glass to press the putty into a solid seal. Smooth the compound with an ungloved finger, and wipe away any caulk that is applied incorrectly or errant drips prior to drying.
