Hidden plumbing leaks can waste water and damage your home long before you see them. Since 1986, John Owens Services has helped homeowners locate slab, water, gas, and irrigation leaks with advanced diagnostic equipment before unnecessary demolition begins.
Not every plumbing leak is easy to find. A pipe may be leaking beneath a concrete slab, inside a wall, under a crawlspace, or beneath landscaping while showing only small warning signs like an unexpected water bill or damp flooring. Finding the exact source before opening walls or concrete helps reduce unnecessary damage and allows repairs to stay focused.
At John Owens Services, we’ve been serving Marin and Sonoma County homeowners since 1986. We use professional leak detection methods to locate hidden water, gas, slab, irrigation, and radiant heating leaks while disturbing as little of your home as possible. Once the source has been confirmed, our licensed plumbing team can explain your repair options and recommend the most practical solution.
If a repair is needed after the leak is located, we can also help with Drain & Sewer Services, Water Heater Repair, and general Plumbing Repair when other systems are affected.
John Owens Services has owned and operated leak detection equipment for over thirty years. We operate the FAST Aqua M300 leak detection system.
