Trusted plumber serving Mill Valley, CA — fast faucet and toilet repair for older hillside homes, with same-day service.
Mill Valley's beloved older homes — from the redwood-shaded cottages off Throckmorton and Cascade Canyon to the mid-century hillside builds in Tam Valley and Homestead Valley — come with plumbing that's seen decades of damp, fog, and seasonal swings. That moisture, combined with original galvanized lines and hard-working fixtures, means leaky faucets, running toilets, and corroded shut-offs are some of the most common calls we get here. John Owens Services has been the plumber Mill Valley homeowners trust since 1986, with technicians who know exactly what to expect behind the walls of a 1940s Cascade-district home.
We offer same-day service across Mill Valley and Marin County in most cases. Call early and we'll do our best to have a licensed plumber (CA #501853) at your door the same day.
Most toilet repairs — a new flapper, fill valve, or wax-seal replacement — are quick, affordable fixes, and we give you an upfront price before we start. We carry common parts on the truck so it's usually done in one visit.
We repair leaky faucets every day, even in homes with aging galvanized or copper lines. We'll fix the faucet and flag any corroded shut-offs or supply lines we spot, so you can decide what's worth addressing now.
