Top Plumbing Leak Detection Services

Non-invasive plumbing leak detection. We pinpoint hidden water leaks under floors, walls, and slabs using acoustic and thermal equipment — no digging, no guesswork.

Service overview

A hidden plumbing leak is the kind of problem that gets worse the longer it sits. The water bill creeps up. A warm spot appears in a hallway. A patch of drywall starts to discolor. By the time you can see the damage, the leak has often been running for weeks or months — and the cost of repair has multiplied.

RGC Leak Detection finds these leaks before they tear up your home. Our process is non-invasive, methodical, and confirmed before anyone picks up a tool. We use the same electronic equipment that municipal water departments and large insurance carriers rely on — and we narrow the leak's location down to within inches.

What plumbing leak detection actually involves

Most homeowners hear "leak detection" and picture a plumber tapping on pipes with a wrench. The real process is closer to a medical diagnostic — a sequence of tests that confirm where water is moving when it shouldn't be.

A typical inspection includes:

  • Pressure testing of supply lines to confirm a leak exists and isolate which line is losing pressure
  • Acoustic listening with sensitive ground microphones to hear pressurized water escaping a line, even through concrete or tile
  • Thermal imaging to identify temperature differences caused by hot or cold water leaking under floors, behind walls, or through ceilings
  • Line tracing to map exact pipe routes so the repair work targets the exact spot we marked

Each method has limits. The skill is knowing which tool to reach for first, and how to confirm a reading before calling a leak found.

Common signs you have a hidden plumbing leak

  • A water bill that jumped without explanation
  • A warm or damp spot on a tile or wood floor
  • The sound of water running when nothing is on
  • Loss of water pressure in one or more fixtures
  • A patch of mildew or mold near a baseboard, ceiling, or under a cabinet
  • A spongy area in carpet
  • A meter that keeps moving when every fixture is off

If two or more of these are happening, you have a leak. The question is where.

From detection to repair — handled end to end

Once we pinpoint your leak, you get a written report with the exact leak location, photos where applicable, and a clear repair scope. Hand it to your plumber, or we can suggest a vetted plumber. You can also choose RGC's Construction Management service if you want the repair managed end-to-end.

If you already have a plumber you prefer to work with, we hand the report directly to them. Either way, you stay in the loop and you're never managing two companies.

What you get from an RGC inspection

  • Pinpointed leak location, accurate to within inches
  • A written report suitable for insurance, real estate, or repair use
  • A flat, agreed-upon estimate before we start work
  • Same-week appointments across the Fort Worth area
  • Forty-plus years of Texas residential construction experience behind every call

If you're dealing with mystery water somewhere in your home, the next step is a phone call. Most leaks can be located in a single visit.

Common questions

Questions we get on the phone, answered straight.

If somethings not covered here, call. The phone consult is the same five minutes whether you book a job or not.

How accurate is acoustic leak detection?

Within a few inches on most pressurized supply lines. The acoustic gear picks up the high-frequency sound water makes when it escapes the pipe wall, and we cross-reference the signal across multiple sensor positions. Thermal imaging confirms when hot-water lines are involved.

Will you cut into my walls or floors?

No. The whole point of acoustic detection is that it's non-invasive. We listen through finished surfaces and confirm with thermal — the only thing we cut into is the time you'd have lost guessing.

How long does a leak detection take?

Most jobs wrap up in two hours from the time Ralph arrives, including the walkthrough, acoustic sweep, thermal confirmation, marking the spot, and writing the report. Larger properties or trickier leaks can run longer; you'll know upfront.

Can you find a leak even when the water is off?

No, a leak only makes acoustic noise when water is moving through it. We do most of the work with the system pressurized; if the leak is intermittent, we may run controlled pressurization tests during the visit to bring the signature out.

Do I need to be home for the inspection?

If someone is on-site during the inspection, they must be 18 years of age or older to grant access and walk through what we're seeing. We prefer to have you (or another adult representative) there for the start and the handoff. If no one can be there, we'll work with whoever is coordinating the visit.
