Leak Detection & Slab Leak Repair in San Anselmo, CA


Water leaks are deceptive. A small stain on the ceiling or a warm spot on the floor can indicate a major pipe failure hiding out of sight. We are San Anselmo, CA’s specialists in water leak detection and repair. We use advanced technology to locate hidden pipe leaks behind walls and under concrete slabs without tearing your house apart.





Precision Slab Leak Detection


A slab leak occurs when a water line buried beneath your home's foundation fails. This is a common issue in San Anselmo, CA. We use acoustic listening equipment and electronic sniffers to pinpoint the exact location of the leak. This allows us to offer targeted repairs—either opening a small hole to fix the pipe or rerouting the line through the attic—minimizing damage to your flooring.

Complete Plumbing Solutions for Homeowners

Minimizing Damage, Maximizing Repair


Our philosophy is non-invasive diagnosis. We don't start cutting drywall or jackhammering concrete until we know exactly where the leak is. Once located, we provide slab leak repair options that fit your budget and your home's layout. We handle everything from the plumbing repair to the moisture mitigation.





Frequently Asked Questions


  • How do you find a leak you can't see? We use microphones to listen for the "hiss" of escaping water and thermal cameras to see temperature differences caused by moisture.
  • What is a pipe reroute? Instead of digging through your concrete slab to fix a bad pipe, we often abandon the old line and run a new PEX pipe through the walls or attic. It is often cleaner and cheaper.
  • Is a slab leak an emergency?
