Why Dallas Homeowners Choose Us for Slab Leak Detection

Certified Master Plumber Report on every job, prepared under Texas License #45825
Non-invasive testing that pinpoints the leak before any concrete is opened
Clear explanation of findings in plain language, not jargon
Real repair recommendations based on evidence, not a guess

A slab leak is not something to guess on. Pinpointing the exact location before repair keeps the opening small and the fix focused, instead of cutting into concrete based on an assumption.

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 before recommending any repair.

What Slab Leak Detection Costs

Leak detection starts at $339. The final price depends on the type of leak, accessibility, and how many lines need to be tested. Slab leak detection starts at $339.

Tools and Equipment We Use

Electronic Leak Detection Amplifier: Amplifies the sound of water escaping a pressurized line to help narrow in on the source.
Geophone / Ground Microphone: Listens through soil and slab to pinpoint underground leaks with far greater accuracy than surface guessing.
Line Pressure Testing Equipment: Isolates individual hot and cold plumbing lines to confirm exactly which line is losing pressure.

Plumbing Code Reference Topics

Slab leak repair work should be evaluated with attention to approved pipe materials, pressure testing requirements, and proper access methods. Always verify the adopted code and local requirements with the authority having jurisdiction.

Frequently Asked Questions (FAQs)

Is professional slab leak detection 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 test take?

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

Will I receive documentation of the inspection?

Yes. Every job includes a certified Master Plumber Report documenting the equipment used, findings, and the marked location.

Can slab leak detection 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.

What happens if a leak is found?

You will receive a report explaining the exact location, whether it’s on the hot or cold side, and repair options so you can decide how to proceed.

Is slab leak detection included in a standard plumbing inspection?

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

How much can slab leak 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.

Are you licensed to perform this work?

Yes. Our leak detection work is performed under Texas License #45825, Registered Master Plumber.

Do you offer emergency slab leak detection in Dallas?

Yes. Emergency slab, pool, gas, and water leak detection is available throughout Dallas and the surrounding North Texas area.

Should I get a reinspection after the slab leak is repaired?

Yes. We recommend a follow-up check after any slab leak repair to confirm the fix addressed the actual leak and no new issues were introduced.

What makes Lone Star Leak Locators different from a general plumber?

Leak detection is our specialty, not a side service. We invest specifically in acoustic detection, electronic locating, and pressure testing equipment that a general plumbing call typically doesn’t require.
