A hidden plumbing leak can waste thousands of gallons of water and cause costly damage before you ever see it. John Owens Services has helped Novato homeowners accurately locate water, slab, gas, and irrigation leaks since 1986 with professional diagnostic equipment and honest recommendations.
Not every plumbing leak is visible. Water can escape beneath concrete slabs, inside walls, under crawlspaces, or below landscaping while only showing subtle warning signs like higher water bills, damp flooring, musty odors, or unexplained moisture.
John Owens Services provides professional leak detection throughout Novato using advanced diagnostic equipment to pinpoint hidden leaks while minimizing unnecessary damage to your home. Once we’ve located the source, we’ll explain the findings clearly and recommend the most practical repair.
Many Novato homes have aging plumbing systems that benefit from careful diagnosis before repairs begin. Whether you suspect a slab leak, underground water line leak, irrigation leak, or hidden pipe leak, we’ll help you identify the problem before unnecessary demolition takes place.
If repairs are needed after the leak is found, we also provide Plumbing Repair, Water Heater Repair, and Drain & Sewer Services throughout Novato.
