Drain Cleaning San Francisco, California | Victorians, the Sunset, the Richmond and the Mission
San Francisco rebuilt itself after 1906, and much of the city’s housing still dates from the decades that followed: Victorians and Edwardians in the Mission, Noe Valley and the Western Addition, and the rows of stucco homes that filled the sand dunes of the Sunset and the Richmond in the 1920s through the 1950s. About 810,000 people live in the city’s 47 square miles, in single family homes, flats, and apartment buildings, with restaurants on nearly every commercial street.

Why San Francisco Property Owners Call California Drain Experts
In San Francisco, the property owner is generally responsible for the side sewer all the way from the building to the city main, including the section under the sidewalk. When that line fails, the owner pays, so knowing its condition matters. A camera inspection shows every section from the cleanout to the main.
Many older San Francisco buildings have a house trap, sometimes called a running trap, near the front of the building. It catches sewer gas but also catches debris, and a clogged house trap can back up the whole building. We check it before assuming the side sewer is blocked.
Most of the city’s housing is close to a century old, with cast iron and clay side sewers that crack, corrode and fill with roots from street trees. In the Sunset and the Richmond, the sandy former dunes can settle under the pipe.
Flats and apartment buildings share stacks and side sewers. One blocked line can affect every unit, and owners need the blocked section identified and documented.
San Francisco’s restaurants, from neighborhood taquerias to busy dining corridors, need grease lines and traps kept clear and inspection-ready. We work before opening or after closing.
Buying a San Francisco home? Ask for a side sewer inspection. You will likely own that line all the way to the main.
