Sewer line repair in San Francisco, CA
A damaged sewer line can be fixed with a spot repair, a trenchless liner, pipe bursting or an open-trench replacement. Which one fits depends on what the camera shows, how deep the pipe is, and what's on top of it, such as a driveway, trees or landscaping.

Sewer line repair for San Francisco homes
Sewer repairs are big decisions, so they should start with a camera video and a locator showing exactly where the defect is. One cracked joint near the foundation is a very different job from a line that's collapsed in three places under the street.

Sewer line repair in San Francisco: what's different
San Francisco owners are responsible for the sewer lateral to the main, including the section under the sidewalk. In Victorian and Edwardian homes in the Mission, Noe Valley and Pacific Heights, that line is often clay or cast iron that has cracked, settled or filled with roots.
Repairs often involve the sidewalk, which needs street permits in addition to a Department of Building Inspection permit. Trenchless lining can sometimes avoid breaking up the sidewalk, depending on the pipe's condition, and a camera inspection first shows what's possible.

Why is my basement floor drain backing up?
When water comes up through the basement floor drain, the main sewer line is usually blocked between the house and the street. Stop using water upstairs, then call a plumber to clear the main line. If it happens more than once, a camera inspection shows the cause.

Should you get a sewer scope before buying a home?
For homes built before about 1980, or with large trees in the front yard, a sewer scope is worth it. A standard home inspection doesn't look inside the sewer line, and in most U.S. cities the buyer will own that line, often all the way to the main.
