Why Homeowners Choose John Owens for Leak Detection Services Petaluma

Since 1986, we’ve earned the trust of homeowners across Petaluma by providing honest recommendations and quality workmanship for gas and plumbing leak detection. From identifying the source of an underground pipe leak to installing a water pipe leak detector, we can handle any gas or water leak detection job!

  • FAST Aqua M300 professional leak-detection system, a 3-in-1 acoustic geophone, hydrogen tracer-gas detector, and pipe locator, the same premium tool water-utility crews and municipal contractors trust
  • Our technician trained in person at the FAST factory in Southern Germany, and the M300 carries 256 adjustable noise filters plus Pyramid Mode to cut through street traffic and background noise
  • More than 30 years operating professional leak-detection equipment, and a family business licensed (CA #501853) and bonded since 1986
  • Sonoma-based crews who know Petaluma plumbing, from west-side Victorian galvanized lines and old clay laterals to newer copper runs on the east side
  • Non-invasive detection that pinpoints the exact spot first, so any repair stays small and targeted instead of guesswork demolition
  • A 4.9-star Google rating from Marin and Sonoma neighbors, with upfront flat-rate pricing and a written diagnosis before any work begins

Frequently Asked Questions

What types of leaks can you detect?

We locate slab leaks, underground water line leaks, gas leaks, radiant heating leaks, and many other hidden plumbing leaks.

Will my walls or floors need to be opened?

Our goal is to pinpoint the leak before any demolition begins with precise video leak detection equipment. Once the source is confirmed, we’ll explain what access is needed for the gas or water leak repair.

Can you repair the leak after locating it?

Yes. Once we’ve identified the problem, our licensed plumbers can recommend and perform many different kinds of gas leak repair, slab leak repair, or plumbing leak repair.

Do you work on older homes in Petaluma?

Yes. Our gas and plumbing leak detection company regularly works on both historic and newer homes throughout Petaluma and understand the unique plumbing systems found in each.

What should I do if I think I have a gas leak?

Leave the area immediately, avoid creating sparks or flames, and contact your gas utility. Once the situation is safe, we can inspect your gas piping. Installing gas leak sensors is helpful in preventing future emergencies.

Do you work on Eichler homes?

Yes. Our team has extensive experience with Eichler plumbing systems and radiant heating systems throughout the North Bay and can offer slab leak detection services.

Why did my water bill suddenly go up in Sonoma County?

It is possible you have a silent leak if you’ve noticed an unexplained uptick in your water bill. Underground pipes, irrigation systems, and toilet flappers can be common culprits of hidden leaks.

Can a plumber find a hidden leak without opening walls or floors?

Absolutely! Between tracer gas leak detection, acoustic listening devices, thermal imaging leak detection, and the Aqua M300 device, there are many different ways to locate a leak without damaging your home.

Do I need a plumber and a leak detection specialist?

You need a leak detection specialist if you think you have a leak somewhere but don’t know the exact location. You need a plumber if you know the location of the leak and need it repaired. Luckily, John Owens Services are onestop plumbers: plumbing and leak detection are offered by our professionals.
