Leak Detection

Find the hidden leak before it costs you a kitchen.

Non-invasive leak detection using acoustic sensors, thermal imaging, and tracer-gas testing. Insurance-ready reports included.

If your water bill is climbing or you smell mildew, we'll pinpoint the leak — without tearing up your home.

Find the leak. Save the floors.

A hidden water leak doesn't just spike your bill — it rots framing, ruins flooring, and grows mold behind the walls. Our leak detection team uses acoustic listening devices, thermal imaging, and tracer-gas testing to pinpoint the leak's exact location without breaking up your slab or tearing out drywall.

Signs of a hidden leak

  • Water bill that suddenly jumped 20% or more
  • Warm or wet spots on your floor
  • Mildew smell with no visible source
  • Water meter that spins when nothing is running
  • Cracks in foundation or walls

How we find it

Most plumbers will guess. We don't. We'll isolate the system, run a static pressure test to confirm the leak, then use the right combination of acoustic listening, thermal imaging, and tracer gas to mark the exact spot — often within an inch.

Insurance-ready reports

If your homeowner's insurance is involved, we provide a written leak detection report with photos, location diagrams, and pressure-test data — everything your adjuster needs to process the claim quickly.

Common questions

How much does leak detection cost?

Most non-invasive leak locates in Northridge are $189–$349 depending on size and complexity. The fee is credited toward repair if you book the repair with us.

How long does a slab leak repair take?

Once located, a typical slab leak repair is 1 day. We can also reroute the line above the slab in many cases, which often saves money and avoids opening the floor.

Will my homeowner's insurance cover this?

Most California policies cover sudden, accidental water damage and the cost of accessing the leak (tear-out and put-back). They typically don't cover the pipe repair itself. We provide insurance-ready paperwork either way.
