Marin County

Plumber in Ross, CA

CNTRline Plumbing works in Ross, the small estate town founded back in 1857 near the Marin Art and Garden Center. We handle the older homes on the elm-lined streets around Ross Common and up along Upper Road. Ross is a bit of a drive south from our Rohnert Park base, and we plan our days so we can give it proper time.

Plumbing in Ross

Most of the houses in Ross were built in the 1940s and earlier, and they sit on large lots with big established trees. Those old cast iron and clay sewer laterals get invaded by roots, and the creeks running through town keep the low areas damp and hard on buried pipe. Original galvanized supply lines in these estates often show up as low pressure and rusty water.

We repair and replace the aging sewer laterals on these older Ross estates, where root intrusion from the mature elms and oaks is the usual cause of a backup.

Neighborhoods we cover: Ross Common, Winship Park, Upper Road, Marin Art and Garden Center.

ZIP codes: 94957.

Questions

Common questions from Ross homeowners

Ross is served by the Ross Valley Sanitary District, along with San Anselmo, Fairfax, Larkspur, Kentfield, and Greenbrae. That district requires a private lateral inspection and a Certificate of Compliance before a property changes hands, and a failed line has to be repaired within 90 days of close of escrow. We do the camera work and the repair, so you are not juggling two contractors on a deadline.
Small jobs are most of what we do. A running toilet, a dripping hose bibb, or a slow tub drain in Ross gets the same licensed plumber as a sewer replacement. Drain clearing starts around $125 and the quote is free.
One of our own licensed plumbers. CNTRline is family run and has been since 2017, so we are not handing your job to a subcontractor we found that morning. We tell you who is coming and roughly when, and you can reach us direct at (707) 308-5599.
