Glass Window Repair

Professional window repairmen work from high off the ground, maneuvering huge glass panes. They adhere to strict safety standards and frequently work in harsh weather conditions.

Wearing protective clothing, cut off the metal glazing points and all glazing putty using an utility knife. A heat gun can soften the old putty and accelerate the removal process.

Examine the type of glass that is broken to determine whether it's a temporary fix, or if a more permanent solution is required.

Then, use a knife to peel off the glazing compound and points that hold the glass in the position. Be sure to keep an eye on the components and their locations to ensure that they can be put back in place later.

After the frame and sash have been removed then you can begin the process of preparing to install the new glass. Make sure you check the opening of the frame is the right size for your replacement window. To allow for expansion and contraction of the glass and frame and contraction to both directions, measure the opening and subtract 1/8 inch. Then, you can purchase double-strength glasses made to these exact measurements. 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.

Depending on the warranty of the window it could be covered by the manufacturer, in which case you must contact them to file an claim. After the new glass has been installed, it is important to cover it with a thin layer of glaziers compound. Once the compound is dry you can paint the frame to be a perfect match.

Repair

Create a two-part mixture of epoxy. They are usually made up of a 50/50 mix of resin and hardener and must be mixed quickly. When the mixture is done apply it to the crack in the glass and allow it to dry. It should take only some minutes but it's important to do it quickly because the mixture is very thick and fast-drying.

After the epoxy has dried, you can take off excess epoxy with a blade. The next step is to scrub the cracked glass. If you don't do it properly, the residue can cause further damage to the glass. Use a putty blade to smooth out the compound around the edge of your window and match it with the frame made of wood.

You could consider using a plastic cover for a more robust option. A trash bag that is heavy-duty or tarp is ideal, however you can also use masking tape to cover the glass. This will prevent the crack from spreading, and will also keep water, wind and insects out.

You can create an interim fix if you are unable to reach the window repairs in a timely manner. Apply a small amount of silicone sealant on the edge of the damaged glass. It won't completely fill the gap between the frame and glass however it will keep the broken piece in place while you fix it.

This is particularly true if the windows are still under warranty and you've experienced numerous problems with condensation or damaged glass.

Sealing

If you have double-pane windows with a cracked seal or newer insulated glass units (IGUs) that have experienced fogging or fog, there are many options for fixing the problem. The most costly option is to replace the insulated unit and frame however it could be required if fog or condensation is causing energy loss. Other options include replacing the existing IGU with a single pane or repairing it by drilling a small hole in the bottom of the unit, and then filling the solution with anti-fog.

You can also fill in the gap between the window frame and the threshold or sill by using a felt strip vinyl v-strip, or a door sweep. Felt can be stapled, glued or nailed into place but doesn't offer much protection against moisture. Vinyl weather stripping that is v-strip is strong and easy to put in however, it can be expensive and is usually reserved for areas that are exposed to high abrasion. Door sweeps are cheap and can be fixed into place however they provide virtually no barrier between the threshold or sill and dust, air, and debris.

To repair a cracked window seal first, use a putty knife to scrape off the caulk. Wearing gloves and eye protection remove the glazing point -- small fasteners with sharp pointed tips that secure the glass to the recess of the frame. After getting rid of the glazing points remove the grooves and sand the wood. Wipe away any sanding residue, then seal the bare wood with a linseed oil based paint or clear wood sealer.

Traditional glazing putty is applied using a putty knife or caulking gun, however a knife provides a better precision and precise application. It also will provide a better seal. Select a putty made specifically for glass, since it is more durable and will adhere better.

Apply a thin layer of glue on the inside of the frame, where it meets the glass. Slide the window into the frame so that the drawn line on the glass is aligned with the edge of the frame. Apply pressure on the glass to press the putty and create a tight seal. Smooth the compound with a gloved hand and remove any drips or caulk that were applied incorrectly before it dries.
