West Marin is not a simple dispatch area. Salt air, long driveways, older piping, hillside pressure swings, propane equipment, and hard-to-reach mechanical rooms all change how a service visit should be handled.

John Owens Services has worked on Marin homes since 1986, and our crew is built for repair-first work: diagnose the issue, show you the options, and replace equipment only when repair is no longer the smart call.

Why West Marin Homeowners Call John Owens

Common West Marin Service Calls

  • Water heater repair or replacement when coastal air, age, or sediment leaves the tank leaking, noisy, or unreliable.
  • Drain cleaning for slow kitchen drains, recurring clogs, and older laterals affected by roots or years of buildup.
  • Leak detection and plumbing repair for pinhole leaks, damp crawlspaces, pressure swings, and older supply piping.
  • Heating repair for furnaces, heat pumps, radiant boilers, thermostats, and controls that fail during cold coastal mornings.
  • Cooling and indoor-air work for homes that need better airflow, cleaner ducts, or more dependable summer comfort.

Frequently Asked Questions

Do you service homes throughout West Marin County?

Yes. We serve West Marin communities including Nicasio, Point Reyes Station, Inverness, Bolinas, Stinson Beach, Muir Beach, Woodacre, Lagunitas, Forest Knolls, and the San Geronimo Valley.

Can you handle both plumbing and HVAC in one visit?

Often, yes. John Owens Services is licensed across plumbing, HVAC, radiant boilers, electrical, and general building work, so mixed-system homes do not always need multiple contractors.

Why is West Marin different from the main Marin County service page?

This page is focused on rural and coastal West Marin conditions: salt air, older piping, propane or boiler heat, narrow access, and longer dispatch routes. The broader Marin County page covers the whole county.

Do you push replacements first?

No. Our service model is maintain first, repair second, and replace only when the system is at the end of its useful life or the repair no longer makes sense.
