Replacing Rotted Door Frames from Humidity in Northern Virginia Homes
What Causes Door Frame Rot In Humid Homes Door frames take a beating from moisture because they sit where outdoor weather, indoor air, and daily use all meet. Rot usually starts when water gets past failed caulk, worn weatherstripping, a bad sill, or a small gap around the trim. A frame that once only needed a little caulk can become a frame that needs partial rebuild or full replacement if the rot reaches the jamb, threshold, or structural members behind the trim.
