Fast, expert drain cleaning and sewer line repair for Lagunitas homes, septic laterals, and creekside properties in the San Geronimo Valley.
Lagunitas sits in the wooded San Geronimo Valley along its namesake salmon creek, where many homes trace back to the original 1913–14 tracts and still run on aging clay or cast-iron laterals feeding individual septic systems — there’s no municipal sewer out here. Add a high winter water table, decades of redwood and oak roots, and seasonal creek-driven groundwater, and slow drains, root-clogged lines, and backed-up laterals are a fact of life. John Owens Services has cleared and repaired these lines across western Marin since 1986, and we know exactly what we’re dealing with before we ever pull a cleanout cap.
We offer same-day service across the San Geronimo Valley, including Lagunitas and Forest Knolls. Call early and our licensed team (CA #501853) can usually clear an active backup the same day.
Many homes here date to the original 1913–14 tracts and still run on clay or cast-iron laterals that crack with age, letting redwood and oak roots in. We camera the line to confirm the cause before recommending cleaning or sewer repair.
Yes. Nearly all of Lagunitas is on septic, so we diagnose the full path from your fixtures through the lateral to the tank and repair or replace failing lines as needed — important in a sensitive creek watershed.
Hydro-jetting clears most root intrusion and restores full flow, and we verify the result on camera. If the lateral is collapsed or badly cracked, we’ll show you the footage and walk through repair options.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
