Slab, Pool, Gas, and Water Leak Detection in Plano, TX

Plano, TX Service Area

We provide slab leak location and detection, along with pool, gas, and water leak detection, for residential and commercial properties throughout Plano and the surrounding North Texas area.

What “Slab Leak Location” Actually Means

Slab leak detection confirms that a leak exists. Slab leak location goes a step further and pinpoints exactly where it is, down to a specific section of the slab, so a repair contractor knows precisely where to open concrete instead of guessing across a wide area. That distinction matters because the size of the opening, and the cost of the repair, depends directly on how accurately the leak was located first.

Detecting that a leak exists is only half the job. Locating exactly where it is keeps the repair small, targeted, and far less disruptive to the home.

Common Signs of a Slab Leak

A water bill that has risen without an obvious explanation
Warm spots on the floor, especially on the hot water side
The sound of running water when every fixture is off
Low water pressure throughout the home
Damp carpet, flooring, or baseboards with no visible source
Mold or mildew smell near the floor in one area of the home

How We Locate a Slab Leak

We start with a water meter test to confirm active water loss, followed by hot and cold line isolation to determine which side of the plumbing system is affected. From there, we use an electronic leak detection amplifier and a geophone ground microphone to narrow the leak down to a specific section of the slab. Every step is documented and included in your certified Master Plumber Report.

What Your Certified Master Plumber Report Includes

The testing methods and equipment used during the visit
Whether the leak is on the hot side, cold side, or both
The approximate marked location of the leak on the slab
Repair recommendations based on the findings, not a guess
Documentation you can hand directly to a repair contractor or insurance company

What Slab Leak Location Costs

Line Pressure Testing Equipment: Isolates individual hot and cold plumbing lines to confirm exactly which line is losing pressure.

Frequently Asked Questions (FAQs)

What’s the difference between slab leak detection and slab leak location?

Detection confirms a leak exists. Location pinpoints exactly where it is on the slab, which keeps a repair small and targeted instead of a wide-area guess.

Is professional slab leak location really necessary?

Yes. Without locating the exact source, repairs often become guesswork, which can mean opening the wrong section of the slab.

How long does a slab leak location visit take?

Most slab leak investigations take one to two hours, depending on the size of the home and number of fixture zones involved.

What is included in the certified Master Plumber Report?

The report documents the testing methods and equipment used, whether the leak is on the hot or cold side, the marked location, and repair recommendations.

Can slab leak location find all types of leaks?

Most hot and cold line slab leaks can be located with electronic amplifier and geophone equipment, though extremely small or intermittent leaks can occasionally take a follow-up visit.

Is slab leak detection included in a standard plumbing inspection?

No. A standard plumbing inspection is typically visual only. Slab leak location uses electronic amplifiers, geophone equipment, and line isolation to locate hidden leaks.

How much can slab leak location and detection cost?

Leak detection starts at $339 for the first two hours and $175 per additional hour. Larger homes, multiple lines, or pools with attached spas take longer, and we confirm the scope and price before work begins depending on complexity.

What are the most common signs of a slab leak?

Warm spots on the floor, rising water bills, the sound of running water when nothing is on, and low water pressure are the most common signs.

Do you need to cut into the slab to run this test?

No. All testing is non-invasive and is performed before any decision is made about opening the slab.

Can a slab leak affect my foundation?

Yes. An ongoing slab leak can saturate soil beneath the foundation over time, which may contribute to soil movement and foundation issues if left unaddressed.

Can I give this report to my own repair contractor?

Yes. The certified Master Plumber Report is yours to share with any repair contractor, insurance company, or home buyer or seller as needed.
