Fast, expert drain cleaning and sewer service for Mill Valley homes — from Blithedale Canyon cottages to Cascade Canyon hillsides.
In Mill Valley, the same redwoods and bay laurels that shade your yard are also the number-one reason drains back up here. The town’s older clay sewer laterals — common throughout the Downtown core, Blithedale Canyon, and the Cascade Canyon hills below Mount Tam — are magnets for root intrusion, which is why a “slow drain” so often turns out to be a main-line problem. John Owens Services has been clearing and repairing Marin sewer lines since 1986, and we know exactly what the local soil, slopes, and tree cover do to a pipe.
Mill Valley’s mature redwoods and bay laurels send roots straight into the older clay sewer laterals common in Downtown, Blithedale Canyon, and Cascade Canyon. We camera the line to find the intrusion and can recommend a lasting fix, not just another snake-out.
Yes. We offer same-day clogged drain service across Mill Valley and Marin, and as a licensed company (CA #501853) we arrive equipped to clear the blockage and scope the line on the same visit.
Absolutely. We clear main sewer lines fouled by root intrusion using cabling and hydro-jetting, then verify the line with a camera so you know it’s actually clear — important on Mill Valley’s long hillside laterals.
Mill Valley’s Sewer Lateral Ordinance can require testing or replacement at point of sale. We can camera-inspect your lateral, document its condition, and walk you through what the city needs.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
