Glass window repair (gnu-darwin.org)

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

Keep the track of the components and where they are so they can be reinstalled.

Once the frame and sash are removed, you can begin preparing to install the new glass. Before you begin, make sure that the opening in the frame is size for the replacement window. To allow for frame and glass expansion and contraction, measure both directions across 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 glazier's pointing or clips to be placed every 6 inches around the window pane.

If the manufacturer is responsible for this, you can call them and submit a claim. After the new glass has been installed, it needs to be covered with a thin coating of the compound used by glaziers. After letting the compound dry then you can paint it to match the frame of the window.

If you have a crack that extends more than an inch, scoring an arc of a razor blade that is just above the crack can help to stop it from spreading further. This method isn't foolproof, but it can slow the development of the crack to a manageable amount until you can take more permanent measures.

Other options include replacing the IGU with a single pane or fixing it by drilling a small hole through the bottom of the unit and 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-strips, or door sweep. Felt can be stapled, glued or nailed into place but doesn't offer much protection against moisture. Vinyl v-strips are easy to install and long-lasting however, it can be costly. It is typically used in areas that are subjected to high abrasion. Door sweeps are cheap and can be put into place however they provide little to no barrier between the sill or threshold and dust, air and other debris.

To repair a damaged window seal first, you must use a putty knife to remove the old caulk. Wearing protective eyewear and gloves take care to remove the glazing points -- tiny fasteners that pin the glass into the frame's recess with sharp edges and pointed ends.

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 glass aligns with the frame's edge. Apply pressure to the glass in order to press the putty to form a tight seal. Smooth the compound using a gloved finger and clean up any mistakenly applied caulk or drips that have escaped prior to drying.
