Many homeowners with historic homes might choose to keep their single pane windows rather than replace them with more efficient double-pane. Beyond the potential historical value, there is one very clear advantage single-pane windows have over their multi-pane counterparts: When the window is broken, it is much easier to replace.

Replacing Windows After a Break

The moment you hear that glass break, swing into action. Start with heavy-duty gloves to protect your hands and a sturdy cardboard box to hold the pieces. Sweep up any glass on the floor, then gently pull the shards of remaining glass from the window frame. Use needle-nose pliers to pull out smaller pieces. Seal the box well and carefully discard it.

Clean the frame well, removing all glazing points and caulking. You might have to use heat to remove caulk that is very old. Measure the window, and head to the local home improvement store to purchase glass that is 1/8 of an inch smaller than the frame. For very old frames, make sure to measure at numerous places to find the right fit.

Caulk all four sides of the window frame, then gently press the glass into the frame, forming a seal with the caulking. Press glazing points between the glass and the frame at regular intervals. Seal the window with a final bead of caulk, smoothing it down carefully as you go. Prime and paint if necessary.

Replacing windows is easy, but it takes some time. With a healthy dose of patience and a steady hand, you can easily replace the glass in your single pane windows and leave it looking as clear as new.
