Many plumbing leaks remain hidden for weeks or even months before homeowners notice them. Water may be escaping beneath a concrete slab, inside walls, below a crawlspace, or underground while causing only subtle warning signs like higher water bills, damp flooring, musty odors, or unexplained moisture. This is where professional water leak detection comes in.

John Owens Services provides professional leak detection throughout Santa Rosa using specialized diagnostic equipment for gas and water leak detection while minimizing unnecessary demolition. Once we’ve identified the source, we’ll explain exactly what we found and recommend the most practical repair options.

From established neighborhoods with aging plumbing to newer homes throughout Santa Rosa, every plumbing system presents unique challenges. Whether you suspect a slab leak, underground water line leak, irrigation leak, or hidden pipe leak, our experienced plumbers can help locate the problem with our advanced video leak detection technology before unnecessary repairs begin.
