Same-day plumbing, heating, and cooling across Marin County — from Eichler radiant slabs in Terra Linda to coastal lines in West Marin.
Marin is a county of original Eichlers, 1920s Mill Valley bungalows, and hillside homes wired into copper-in-slab radiant systems most contractors won't touch. John Owens Services has worked these houses since 1986 — we know why salt air off Tomales Bay eats supply lines, why a Ross Valley crawlspace floods every wet winter, and how to keep a 60-year-old radiant loop running without tearing up the floor. One family-run team handles your plumbing, heating, and AC, usually in a single visit.
Yes — John Owens Services is fully licensed (CA #501853) and insured, and we cover the entire county from Sausalito to Point Reyes Station, including San Rafael, Mill Valley, Novato, and the Ross Valley. Same-day service is available when you call early.
We do. Our techs service forced-air furnaces, heat pumps, and AC, and we're one of the few Marin teams that specializes in mid-century and Eichler in-slab radiant heating — repairing the original loops rather than recommending a full tear-out.
In most cases, yes. Our trucks are stocked to fix the majority of heating and cooling problems on the first visit, and we prioritize getting you back up and running fast.
Aging copper, salt air along the coast, mature tree roots in old sewer laterals, and hillside pressure swings all take a toll. We've worked these exact conditions since 1986 and use materials chosen to hold up to them.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
