Expert boiler repair, installation, and radiant heating for Mill Valley homes — from Old Mill cottages to hillside Homestead Valley.
Mill Valley’s wooded canyons and 1920s-era cottages, mid-century hillside homes, and damp redwood-shaded lots make steady, even heat a real priority — and many older homes here still run on hydronic boilers and radiant systems that need expert care. John Owens Services has kept Mill Valley families warm since 1986, troubleshooting failing boilers, replacing aging cast-iron units, and installing modern radiant floor heat tuned to the town’s foggy, cool microclimate. Whether you’re off Throckmorton near downtown, up Cascade Canyon, or in Homestead Valley, we know how these systems behave in Mill Valley’s housing stock.
We offer same-day boiler repair throughout Mill Valley whenever scheduling allows — including downtown, Homestead Valley, and the canyon neighborhoods. As a licensed contractor (CSLB #501853), we diagnose the real fault before quoting any work.
Yes — radiant floor heating delivers quiet, even warmth that suits Mill Valley’s cool, foggy microclimate and works beautifully in both older remodels and new builds. We design each system around your home’s flooring and layout for efficient, draft-free comfort.
If your Mill Valley boiler is over 15–20 years old, leaking, or needing frequent fixes, a new high-efficiency boiler installation usually pays off in lower bills and reliable heat. We’ll give you an honest side-by-side so you can decide with real numbers.
Absolutely. Many Mill Valley homes still run cast-iron radiators and hydronic loops, and we repair, rebalance, and upgrade these systems regularly while keeping their original comfort and character intact.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
