Sewer Line Repair & Replacement in Sunnyvale, CA
Sewer lateral work is the biggest-ticket residential plumbing job in Sunnyvale, and bids for the same line can differ by thousands. The local context: ranch homes and Eichler tracts, plus some of the Bay Area’s largest mobile-home parks, which means clay or cast-iron laterals — plastic pipe only took over in the 1970s on many streets — exactly the pipe generations that fail first.
$1,500–$25,000 is the honest statewide bracket for sewer line repair & replacement; where your Sunnyvale quote lands inside it depends on scope and labor ($150–$250/hr locally, $90–$150 to get a truck out). Two or three written estimates narrow it fast. For the state-wide view, see the Sewer Line Repair & Replacement cost guide.
