Tiburon's housing tells a story in heating systems: 1950s and '60s Lagoon homes with hydronic tubing cast into their slabs, mid-century post-and-beam hillside houses, and Old Town cottages that have been reworked for decades. Many still run on radiant floor heat and hydronic boilers, and the constant marine air off Richardson Bay is hard on every metal component in the loop. John Owens Services has kept these systems running across the Tiburon Peninsula since 1986, from a no-heat morning call to a full high-efficiency boiler swap.

Why Tiburon Homeowners Choose John Owens

  • Decades of hands-on work with Peninsula radiant-slab systems — the embedded copper and PEX loops common in Lagoon and Eichler-era Tiburon homes, where a buried leak or air-locked zone needs experience, not guesswork
  • Licensed California contractor (CA #501853), family-run since 1986, with a 4.9-star Google rating and happy customers from Marin and Sonoma homeowners
  • Same-day service when the heat quits — we understand a cold radiant floor on a damp bayside morning is not something that waits
  • We size and install modern high-efficiency condensing boilers correctly for low-temperature hydronics, so your radiant floors actually perform and your gas bill drops
  • Straight diagnosis on aging systems: we'll tell you honestly whether a pump, zone valve, or expansion tank fixes it, or whether a 20-plus-year-old boiler is past its service life
  • Familiar with the corrosion and pressure issues that marine air and older Tiburon plumbing create — we fix the cause, not just the symptom

Signs You Need Boiler & Radiant Heating in Tiburon

  • No heat or lukewarm floors — especially one cold zone or room while the rest of the house warms, a classic sign of a stuck zone valve, air-locked loop, or failing circulator pump
  • Banging, gurgling, or kettling sounds from the boiler, often trapped air or scale buildup in an older system
  • System pressure dropping below 12 PSI, or a relief valve that keeps dripping — both point to a leak or a tired expansion tank
  • Rising gas bills with no comfort improvement, a hallmark of a boiler losing efficiency or short-cycling
  • A boiler past 15-20 years old, or radiant floors that never recovered after the last cold snap — worth an assessment before winter

Frequently Asked Questions

How fast can you handle boiler repair in Tiburon?

We offer same-day service across the Tiburon Peninsula whenever possible, including Old Town, Paradise Cay, and the Belvedere Lagoon. As a licensed California contractor (CA #501853) since 1986, we diagnose and repair most hydronic boilers on the first visit.

Do you service radiant heating in Tiburon's older Lagoon and hillside homes?

Yes. Many Tiburon homes from the 1950s and '60s run hydronic radiant floor heat, and we're experienced with their embedded slab loops, zone valves, and circulator pumps — including tracking down buried leaks and clearing air-locked zones.

Is it worth repairing my boiler or should I consider boiler installation?

If your boiler is under 15 years old, a repair is usually the smart call. Past 20 years, or with repeated failures, a new high-efficiency condensing boiler often pays for itself in lower gas bills — and we'll give you an honest recommendation either way.

Will a new boiler work with my existing radiant floors?

In almost every case, yes. We size and configure modern condensing boilers specifically for low-temperature radiant hydronics, so your existing Tiburon floor system runs more efficiently and heats more evenly than before.
