Water Damage Restoration San Francisco: Old Pipes, Shared Walls, One Contract

The building is old, and your neighbor shares your wall.

Much of the city's housing stock predates the Second World War, and a great deal of it still runs original galvanized steel supply lines and cast-iron drains. Galvanized pipe corrodes from the inside out, so it fails without any warning on the surface, and by the time a stain appears in the ceiling below, the water has been traveling for a while.

The second problem is geometry. Victorian and Edwardian buildings, converted flats, and mid-block infill share party walls and floor assemblies, which means a loss in one unit becomes a loss in two or three. That changes the job immediately: containment, coordination with neighboring owners or the HOA, and documentation that separates whose damage is whose before anybody's adjuster starts asking.

Then there is what sits below. Garages, storage, and in-law units below grade take on water from storm drains, sidewalk vaults, and hillside runoff during winter rain, and the electrical serving them is usually the first thing submerged. That is exactly the part most restoration companies have to subcontract, and the part our C-10 crew handles on the first visit.
