Accurate Slab Leak Detection Beneath Your Foundation
A leaking water line beneath a concrete slab can waste water, damage flooring, create moisture problems, and affect the surrounding structure. Our slab leak detection service is designed to identify the likely location and path of the leak so repairs can be planned with less unnecessary disruption.
What Is a Slab Leak?
A slab leak occurs when a pressurized water line below or within a building’s concrete foundation begins leaking. Pipes may fail because of corrosion, shifting soil, abrasion, high water pressure, age, or installation problems.
Locating a slab leak requires more than finding a warm or damp spot. We assess the symptoms, isolate plumbing lines when appropriate, and use tools such as acoustic equipment, pressure testing, and thermal imaging to narrow down the affected area. Once the leak is located, we can discuss repair approaches based on the pipe layout and site conditions.
Signs You May Need This Service
Warm or unusually damp areas on the floor
The sound of water running beneath the floor
Cracks, discoloration, or moisture around flooring
Low water pressure or unexplained water use
A sudden or steady increase in the water bill
Moldy or musty odors near the floor
How We Locate the Problem
- Review the property's symptoms, plumbing layout, and water-use history.
- Check fixtures and accessible piping to rule out above-slab leaks.
- Perform line isolation, pressure testing, and instrument-based detection as appropriate.
- Mark the suspected leak area and review practical repair options.
California Code and Permit Considerations
A slab-leak diagnosis does not by itself authorize cutting concrete or altering a foundation. The repair method—such as focused access, a reroute, or replacement—depends on the confirmed pipe location, pipe condition, building construction, and approved scope.
Resulting water-piping work should use approved materials and joints, protect piping at penetrations, maintain required support, and be pressure-tested and inspected when required. Structural cutting and finish restoration should be assigned separately when they are outside the plumbing scope.
