We Find the Leak Before We Open Anything

Electronic leak detection in Las Vegas — no guessing, no unnecessary damage, no surprises on your bill.


Licensed Las Vegas plumbers have been using electronic leak detection equipment to locate slab leaks, underground leaks, and hidden water leaks without tearing into walls or floors for over 15 years. MC Plumbing diagnoses the problem precisely before any demolition is authorized. You know exactly what you're dealing with — and exactly what it will cost — before work begins.


If your water bill keeps climbing and nothing's visibly dripping, that's not a mystery. That's a leak. Underground and slab leaks can lose hundreds of gallons a day with no surface signs at all. Professional detection is the only reliable way to find them.

Why Slab Leaks Are So Common in Las Vegas

Las Vegas sits on caliche-heavy soil that shifts with temperature and moisture changes. That constant ground movement puts pressure on the copper pipes running beneath your foundation, and over time, those pipes crack. The result is a slab leak — a pressurized water line failing below your concrete — and it's one of the most common plumbing problems in Clark County.


Left undetected, slab leaks erode your foundation, spike your water bill, and create mold conditions inside your walls. Found early, they're a contained repair. The difference between those two outcomes is usually how quickly you call.

Common signs of a slab leak in Las Vegas homes:

  • Water bill increasing month over month with no change in usage
  • Warm or damp spots on your floor, even with no visible water
  • The sound of running water when all fixtures are off
  • Cracks appearing in your flooring or baseboards
  • Low water pressure throughout the house

How We Locate Leaks Without Tearing Up Your Home

MC Plumbing uses electronic leak detection equipment to pinpoint the exact location of a leak before anything is opened. No exploratory demolition. No cutting into drywall on a hunch.

Step 1: Pressure Testing

We isolate sections of your plumbing system to confirm a leak is present and identify which line is losing pressure. This step rules out false alarms before any detection equipment is deployed.

Step 2: Electronic and Acoustic Detection

Using listening devices and electronic amplification, we trace the sound signature of escaping water through your slab or walls. This is how we find underground leaks and slab leaks without opening anything.

Step 3: Precise Location Marking

We mark the exact location of the leak on your floor or wall before any work begins. You see where the problem is, and we discuss the repair options and cost together — before a single tool touches your home.

Step 4: Repair or Refer

Once the leak is located, we perform the repair or, where a camera inspection of your sewer or drain line is warranted, connect that work to the same visit.

Questions About Leak Detection in Las Vegas Q

  • How do I know if I have a slab leak in my Las Vegas home?

    The most common signs are a rising water bill with no explanation, warm or wet spots on your floor, the sound of running water when everything is turned off, and new cracks in your flooring or baseboards. Las Vegas soil conditions make slab leaks more common here than in most other cities. If you're seeing any of these signs, call for a professional inspection — the sooner it's found, the less it costs to fix.

  • Will you have to tear up my floors to find the leak?

    No. MC Plumbing uses electronic and acoustic detection equipment to locate leaks precisely before anything is opened. We mark the exact location first, then discuss the repair with you. No exploratory demolition, no guessing.

  • Why is my water bill so high if I can't see any water leaking?

    Underground leaks and slab leaks lose water below your foundation or inside your walls — places you'd never see from the surface. A pressurized line can lose hundreds of gallons per day without a single visible drip. If your bill is rising and nothing's dripping, a hidden leak is the most likely cause.

  • How much does leak detection cost in Las Vegas?

    MC Plumbing provides a free estimate before any work begins. Detection and repair costs vary based on where the leak is located and what's required to access it. Because we locate the leak precisely before opening anything, you're never paying for exploratory work.

  • How long does leak detection take?

    Most leak detection appointments take one to three hours depending on the size of the home and complexity of the plumbing. Once the leak is located, we can usually discuss repair options the same day.
