Water damage & mold help in San Francisco, CA
San Francisco's housing is old and dense: Victorian and Edwardian homes in the Haight, Mission and Noe Valley, and 1930s–50s row houses in the Sunset and Richmond. Winter storms, fog-driven moisture, earthquakes and aging plumbing drive most water damage. Many homes have garages and in-law units at street level, below the main living floors.

San Francisco homes and water damage
Victorians and Edwardians have plaster walls, original wood and older plumbing, while Sunset and Richmond row houses share walls and often have ground-floor garages converted to living space. Many homes have been divided into flats or have added in-law units, so leaks often affect more than one household.
Winter storms and leaks
Atmospheric river storms, like the 2022–23 series, cause roof leaks and flood low-lying streets.
Fog and moisture
Persistent fog in the Sunset and Richmond keeps homes damp, encouraging mold.
Earthquakes
Earthquakes can break pipes and water heaters; the 1989 Loma Prieta quake damaged buildings across the city.
Street-level units
Garages and in-law units below street level take on water during heavy rain.
Older plumbing
Victorian and Edwardian homes often have aging galvanized supply lines and cast-iron drains.
Multi-unit leaks
In flats and condos, leaks from upper units travel down through ceilings.
