How we find leaks (non-destructive first)

Acoustic listening for pressurized lines • Thermal camera to track warm/cold anomalies • Moisture meters and salts testing • Tracer gas (nitrogen/hydrogen) for pinpointing • Borescope through tiny access holes.
We document findings with photos/video so fixes are clear and fast.

Slab leaks: repair options (we’ll tell you the honest path)

  • Spot repair (open slab, fix, re-pour) when the line is otherwise healthy.

  • Overhead/through-wall reroute to bypass problem sections—less demolition, great for older copper-in-slab homes.

  • Partial/whole repipe if leaks are recurring or the pipe is failing.

If the fix touches piping (new route, replacement, or significant repair), LADBS plumbing permits apply—we handle those.

Fix the cause (not just the wet spot)

  • High static pressure (>80 psi) accelerates leaks; we test and add a PRV if needed (California code requires pressure ≤80 psi). Closed systems also need a thermal expansion tank.

  • Old galvanized / pinhole copper → targeted repipe (Type L copper or PEX-A).

  • Drain leaks → repair/replace ABS, add cleanouts, correct slope/vent issues.

Our process (LA homes & small commercial)

  1. Confirm the leak (meter/pressure tests)

  2. Locate precisely (acoustic/thermal/tracer gas)

  3. Upfront quote — your $75 diagnostic is applied

  4. Permit & repair (when required) with code-compliant materials

  5. Pressure/functional test and clean finishes

  6. Prevention: PRV/expansion tank checks; maintenance tips
