Rotted wood window frame water damage

Rotten frame: save the window

A rotten wood window frame does not necessarily mean you must replace the complete window at $800-2,000. In most cases, RBQ partner glaziers can repair or replace only the frame for $200 to $600 — a 50 to 70% savings if the double thermo pane is still in good condition. This approach preserves your existing glazing while restoring the seal and aesthetics of your window.
