Interior Leak Detection

Exterior & Underground

Water-System Specific

Commercial & Specialty

A leak under a slab and a leak at a pool skimmer are both “water leaks,” but they share almost nothing in how they are found. Slab work leans on acoustic listening through concrete and thermal imaging of hot-water lines. Pool work leans on pressure testing isolated plumbing loops and dye verification at fittings. Send the wrong toolkit, or the wrong mental model, and the diagnosis suffers.

Specialization also prevents the most common misdiagnosis in the trade: confusing where the water shows up with where it originates. Water travels along pipes, framing, and soil before it surfaces, so a ceiling stain two rooms from the actual breach is routine. Each of our 15 services trains on the failure patterns of its own system, which is what lets a specialist look past the symptom and test the true source.

California housing makes this matter more. The state mixes slab-on-grade tracts, raised-foundation bungalows, hillside homes with complex drainage, mid-century plumbing, new PEX manifolds, sprawling irrigation, and pools, sometimes all on one street. Matching the specialty to the system is how an inspection stays fast, accurate, and minimally invasive.

More pipe runs outside the house than inside it, under slabs, through yards, along the service lateral from the street. These six specialties cover every buried and outdoor scenario, each with a genuinely different diagnostic angle.

• Slab leak detection: pinpoints pressurized leaks in water lines running beneath or within concrete slab foundations, the classic California tract-home problem, using acoustic and thermal methods.
• Underground pipe leak detection: traces and locates failures in deep buried pipe runs, where acoustic correlation and electromagnetic line locating do the heavy lifting.
• Outdoor water line leak detection: covers yard and landscape supply lines: hose bibbs, garden lines, and secondary runs that surface as soggy patches and inexplicable usage.
• Water service line leak detection: focuses on the main lateral from the street or meter to the house, the highest-volume line on most properties, where a break wastes the most water fastest.
• Yard meter box leak detection: meter-side diagnostics: distinguishing failures in the meter assembly and its connections from downstream problems, right at the box itself.
• Irrigation and sprinkler leak detection: zone-by-zone testing of sprinkler laterals, valves, and heads to find the cracked line or stuck valve behind a flooding or dead zone.

Bigger pipes, longer runs, occupied buildings, and exterior infrastructure, commercial work scales the same non-invasive toolkit to business properties.

• Commercial leak detection: offices, retail, restaurants, hotels, and industrial sites: multi-zone systems inspected on a schedule built around your operations.
• Parking lot leak detection: underground lines beneath asphalt and concrete paving, where ponding, sinkholes, or sub-base saturation signal a failing line that cannot simply be dug up on a guess.

Property managers dealing with a suspected main-line failure or unexplained common-area usage can call (833) 382-2711 to plan an inspection around tenants and business hours.

You do not need to know which of the 15 services your leak belongs to before you call. Booking starts with the symptom, not the specialty. One call to (833) 382-2711 reaches triage: you describe what you are seeing, we ask a few narrowing questions, and the visit gets matched to the right specialty and equipment before anyone rolls.

Every service on this page includes the same foundations: a meter or pressure check that proves water is being lost, a non-invasive survey with acoustic and thermal equipment, a marked location when a leak is confirmed, and written findings you keep. If the first specialty turns out to be the wrong one, the findings say so honestly and point at the right next step instead. And if water is actively spreading while you read this, skip the comparison entirely and go straight to emergency leak detection.

New to the company? The Leak Detection California homepage explains how the whole process fits together, from first call to confirmed location.

Most callers do not know the name of their leak, and they should not have to. Start from the symptom instead. Water where it should not be, with no visible source, is a job for general water leak detection. A warm floor or a bill climbing for months points at the slab service. A pool losing level faster than evaporation explains is pool and spa work.

If the symptom is a meter that will not sit still, start with the meter and service line pages. And if water is actively spreading right now, skip the reading: the emergency page and a phone call are the whole decision. Every service ends at the same place anyway, a marked location and a clear explanation of what happens next.
