A plumbing leak isn’t always obvious. Water can escape beneath concrete slabs, behind walls, inside crawlspaces, or under landscaping while causing only subtle signs like higher water bills, musty odors, damp flooring, or reduced water pressure. This is where water leak detection is vital.

John Owens Services provides professional leak detection throughout Petaluma using specialized equipment for gas and plumbing leak detection while minimizing unnecessary demolition. After identifying the source, we’ll explain exactly what we found and discuss the most practical repair options.

From historic homes in downtown Petaluma to newer neighborhoods throughout Sonoma County, we understand the plumbing systems found in local homes. Whether you’re dealing with a slab leak, underground water line leak, irrigation leak, or hidden pipe leak, we’ll help pinpoint the problem before repairs begin.

If repairs are needed after the leak has been located, we also provide Plumbing Repair, Water Heater Repair, and Drain & Sewer Services throughout Petaluma.
