Plumber in Larkspur, CA
CNTRline Plumbing takes care of Larkspur, including the Queen Anne Victorians and Craftsman cottages along the downtown stretch of Magnolia Avenue. That historic district is on the National Register, and we treat those old houses with the care they need. We come out from our Rohnert Park shop for scheduled work and after-hours calls alike.

Plumbing in Larkspur
Downtown Larkspur is full of homes over a hundred years old, and many still have their original drain and supply piping tucked behind finished walls. Up in Hillview the houses are built into steep redwood-covered slopes, which makes water heater venting and drain slope tricky. Down near Corte Madera Creek, along Riviera Circle, the low ground and old laterals lead to backups and root problems.
We handle gas line work on the vintage downtown houses where the original piping is undersized for a modern range or a tankless heater.
Neighborhoods we cover: Downtown Larkspur, Magnolia Avenue, Hillview, Riviera Circle, Baltimore Park.
ZIP codes: 94939.
