A straightforward like-for-like swap is typically done in half a day: remove the old door, install new tracks, springs, and sections, then balance and safety-test. Custom-fit openings — common in older San Francisco homes where nothing is square — can run longer, and we will tell you that at the quote stage.
For the fog belt, powder-coated steel with galvanized hardware or aluminum is the practical choice — plain steel edges rust visibly within a few years this close to the ocean. Wood looks right on older SF facades but demands regular sealing on the weather side; composite gives the look with less upkeep.
We haul it away as part of the installation price — sections, springs, tracks, and hardware. If you want to keep anything (some owners reuse quality wood sections), say so before the crew loads up.
