Exterior and Patio Door Frame Rot in Daly City

A soft jamb is only the visible edge

At an exterior or patio door, swelling, peeling paint or a soft lower jamb can be connected to the threshold, brickmould, sill pan or nearby floor. Daly City fog and wind-driven rain make repeated wetting worth investigating, but the actual source cannot be inferred from the symptom alone.

Decide what needs opening

Photograph the whole opening and close views of the lower corners from safe access. Ask whether the scope covers only replaceable trim or requires checking the adjacent frame and floor. A dragging door is not, by itself, proof of a structural problem. Window or door-unit replacement and water-source correction may be separate trades.
