From the hillside crawlspaces of Mill Valley and Tiburon to the older neighborhoods of Santa Rosa and Petaluma, North Bay homes hide a lot of aging pipe — galvanized supply lines, polybutylene runs, and clay sewer laterals that root intrusion finds every winter. John Owens Services has worked on that exact plumbing for nearly four decades, so our plumbers start by tracing the real cause instead of guessing at the symptom. Whether it is a slab leak in San Rafael, a failing sewer lateral in Sebastopol, or a burst line during the first big storm, we arrive with a fully stocked truck and a fix that holds.

Why Homeowners Choose John Owens

  • A family-run shop here since 1986 with a 4.9-star Google rating — these crews know how Marin hillside pressure and Sonoma's hard water actually behave, not just the textbook version
  • Fully licensed (CA #501853) and insured C-36 plumbers, so repipes, gas lines, and sewer-lateral work are all done to code and permitted properly
  • Same-day service whenever we can get to you — most repairs are completed in a single visit
  • Real diagnosis first: we trace slab leaks, hidden moisture, and recurring backups to the source before anything gets opened up, which matters in older North Bay homes with finished basements and tight crawlspaces
  • Honest repair-vs-replace guidance — on a 1950s galvanized system or a corroded sewer lateral we tell you when a patch is fine and when replacement is the smarter long-term call
  • Warehouses on Wheels: stocked trucks and factory-trained techs mean most repairs and many installs wrap in a single visit

Signs You Need Plumbing in

  • Water pressure that drops when more than one fixture runs, or rusty/discolored water — common signs of failing galvanized supply lines in pre-1970s North Bay homes
  • Recurring drain or sewer backups, gurgling toilets, or sewage odor in the yard, which often point to root intrusion or a collapsed clay lateral
  • A spike in your water bill with no explanation, or a warm spot on a slab floor — classic symptoms of a hidden under-slab leak
  • A faucet, toilet, or garbage disposal that drips, runs, or won't drain right, with moisture or warping building up underneath the cabinet or floor
  • Standing water in a crawlspace or low-lying yard after heavy winter rain, where a sump pump or drainage fix protects the foundation

Frequently Asked Questions

Do you offer emergency plumber service in Marin and Sonoma County?

Yes — burst pipes, sewer backups, water heater failures, and major leaks get priority scheduling, and we dispatch a licensed plumber to most of the North Bay the same day. Call any of our office lines (Santa Rosa, San Rafael, or Petaluma) and we'll get someone moving fast.

How much does plumbing repair cost in the North Bay?

It depends on the fix — a faucet cartridge or running toilet is straightforward, while a sewer lateral or whole-house repipe is a bigger job. Our licensed plumbers (CA #501853) give you a clear estimate before any work starts, and we'll tell you honestly when a repair beats a replacement.

Can you handle the older galvanized and clay-pipe systems common in Marin and Sonoma homes?

Absolutely — much of our plumbing services work is on the North Bay's aging housing stock, from galvanized supply repipes to clay and Orangeburg sewer-lateral replacement. We camera-inspect the line first so you know exactly what you're dealing with.
