Same-day water heater repair, replacement, and tankless installation for Mill Valley homes, from the downtown canyon to the Tam Valley flats.
Mill Valley’s older shingle and Craftsman homes, tucked into the wooded hillsides below Mt. Tamalpais, are hard on water heaters — decades-old tanks fed by galvanized lines, tight closet installs, and the famous coastal fog that keeps crawlspaces damp and rusts steel from the outside in. Whether your unit sits in a Strawberry condo, a creekside cottage in Homestead Valley, or a hillside home off Edgewood, John Owens Services repairs, replaces, and upgrades it fast. We’ve kept hot water running across Marin since 1986, and our trucks know every winding road from Almonte to Alto.
Cost depends on tank vs. tankless, your home’s gas and venting setup, and whether aging galvanized lines need updating — common in older Mill Valley homes. We give a clear, upfront quote before any work, and as a licensed contractor (CA #501853) the price includes proper permitting.
Yes. We offer same-day water heater repair across Mill Valley — downtown, Tam Valley, Strawberry, Homestead Valley, and the surrounding hillsides — with stocked trucks so most fixes happen in one visit.
For space-tight hillside and downtown homes, a tankless water heater is a popular upgrade: it mounts on a wall, frees the closet or crawlspace, delivers endless hot water, and lasts longer than a tank. We’ll confirm your gas line and venting can support one before recommending it.
It can be. Corroded galvanized supply lines restrict flow and rust water, so we inspect them during any water heater installation and replace the connections as needed to protect your new unit and your water quality.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
