Water bill spiked? Damp spot you can’t explain? We’ll connect you with an independent local plumber who finds and fixes hidden leaks — 24/7, anywhere in the US.

📞 CALL NOW: (877) 926-9959

💯 Free to call. No obligation.

Most leaks don’t announce themselves. There’s no burst, no flood — just a water bill that climbed for no reason, a musty smell that won’t go away, or a patch of drywall that’s damp to the touch. By the time you notice, water may have been running behind a wall or under the slab for weeks.

That’s what leak detection is for. One call connects you with an independent plumber in your area who uses leak detection equipment to track down hidden leaks — under floors, behind walls, in the slab, or along the water line — without tearing the house apart to find them.

We’re not a plumbing company and we don’t do the work ourselves. We connect you with independent contractors in our nationwide network, and they quote you directly — so you know the price before anyone starts. Calling is free, and you’re under no obligation.

SIGNS YOU MAY HAVE A HIDDEN LEAK

Your water bill jumped

A bill that climbs with no change in how much water you use is one of the clearest signs. Water is going somewhere you can’t see.

The meter moves with everything off

If your water meter keeps ticking when no tap, toilet, or appliance is running, water is escaping somewhere in the system.

Damp or stained drywall

Discolored patches, bubbling paint, or a soft spot on a wall or ceiling often means water is collecting behind it.

A musty or mildew smell

A persistent damp smell with no obvious source usually means moisture — and often mold — building up out of sight.

A warm spot on the floor

A warm patch on a slab floor can signal a hot-water line leaking underneath — a slab leak, which needs specialized detection.

The sound of running water

Hearing water run when nothing’s turned on, or a drop in water pressure, can both point to a leak somewhere in the lines.

HOW TO CHECK FOR A LEAK YOURSELF

Before you call, there’s a simple test that tells you whether water is escaping somewhere in your system — the water meter test:

  • 1
    Turn off all water in the house Every tap, the dishwasher, the washing machine, the icemaker — everything that uses water. Don’t flush a toilet during the test.
  • 2
    Find your water meter and note the reading It’s usually in a box near the street or where the line enters the house. Write down the numbers, or note where the little dial sits.
  • 3
    Wait an hour without using any water Leave it completely alone. If someone flushes or runs a tap, you’ll have to start over.
  • 4
    Check the meter again If the reading moved at all with everything off, you almost certainly have a leak somewhere. That’s the point to call — locating exactly where it is takes the right equipment.

The test tells you whether you have a leak. Finding where — especially behind a wall or under a slab — is what the plumber’s detection tools are for. If the meter moved, call and describe what you found.

WHAT LEAK DETECTION TYPICALLY COSTS

Cost depends on where the leak is and how hard it is to reach. Locating a leak is often a separate step from repairing it, and a slab leak under concrete is a bigger job than a leaking supply line. These are broad national ranges to give you a rough idea before you call — your contractor quotes you directly, and we don’t set or influence that price.

JobTypical range
Leak detection / diagnosis$150 – $500
Slab leak detection$200 – $700
Pipe or supply line leak repair$150 – $800
Slab leak repair$2,000 – $6,000+
Whole-house leak inspection$150 – $400
Emergency / after-hours call-outPremium applies

Ranges are general estimates only and are not quotes. Actual pricing depends on your location, where the leak is, how accessible it is, and the contractor you choose.

LEAK DETECTION QUESTIONS

How do plumbers find a hidden leak?

They use specialized equipment — acoustic listening devices, moisture meters, thermal cameras, and pressure tests — to narrow down where water is escaping without opening up walls or floors first. The goal is to pinpoint the spot so repairs are as targeted as possible.

What is a slab leak?

A slab leak is a leak in one of the water lines running beneath your home’s concrete foundation. Signs include a warm spot on the floor, an unexplained water bill, or the sound of running water with everything off. They need specialized detection, since the pipe is under concrete.

Why is my water bill suddenly so high?

If your usage hasn’t changed but the bill has, a hidden leak is one of the most common causes — a running toilet, a leaking supply line, or a leak underground or in the slab. The water meter test on this page is a quick way to check whether water is escaping somewhere.

Can a small leak really cause damage?

Yes. A slow leak that runs for weeks can rot framing, ruin drywall, and grow mold long before you see a drip. Catching one early is almost always cheaper than dealing with the damage later — which is why the odd signs are worth acting on.

What does it cost to call you?

Nothing. Calling us is free and there’s no obligation. The plumber quotes you directly, and you decide whether to go ahead. We’re paid by contractors for referrals, never by you.

Do you do the work yourselves?

No. We’re a referral service. All work is performed by independent third-party contractors who are responsible for their own licensing and insurance. We recommend verifying a contractor’s credentials before authorizing work — most states have a free online license lookup.

FIND THE LEAK BEFORE IT FINDS YOU.

A hidden leak only gets more expensive the longer it runs — in water bills and in damage. One free call connects you with a local plumber who can locate and fix it.
