Slab Leak Detection
Slab Leak Detection in Austin, TX
A slab leak can silently damage your foundation and spike your water bill. Our electronic detection pinpoints the exact location of the leak without demolition — so you know exactly what you're dealing with before any concrete is touched.
What Is a Slab Leak — and Why Detection Matters
A slab leak is a leak in the plumbing lines that run beneath your home's concrete foundation. In Central Texas, where most homes are built on slab foundations, these leaks are common — caused by shifting clay soil, corrosion, abrasion, or the natural expansion and contraction of copper pipe under repeated temperature changes.
Left untreated, a slab leak can erode the soil beneath your foundation, leading to cracks in walls and floors, uneven settling, and tens of thousands in structural damage. It also means water running 24/7 under your slab — often first noticed as a mysteriously high water bill.
The good news: modern electronic leak detection means we can find the exact location of a slab leak without tearing up your floors. Our master plumbers use acoustic listening equipment, pressure testing, and thermal imaging to pinpoint the leak to within inches — then discuss the least invasive repair path.
Signs You May Have a Slab Leak
Our Slab Leak Detection Process
Pressure Testing
We isolate and pressure-test each zone of your under-slab plumbing to confirm which line is leaking and how severely — no guessing.
Electronic Acoustic Detection
We use specialized acoustic listening equipment to hear the leak through the slab, pinpointing its location to within inches.
Thermal Imaging
For hot-water leaks, thermal imaging reveals temperature anomalies in the floor that confirm the leak's exact position.
Clear Report & Options
We show you exactly where the leak is, explain your repair options (spot repair, re-route, or re-pipe), and give you flat upfront pricing for each — before any concrete is opened.
Slab Leak Detection Across Austin and Surrounding Communities
Central Texas clay soil is notoriously expansive — it swells when wet and shrinks when dry — which makes slab leaks a particularly Austin problem. Homes across Round Rock, Pflugerville, Georgetown, and the surrounding communities sit on the same reactive soil, and the older copper under-slab lines in central Austin neighborhoods are reaching the age where pinhole leaks become common.
If you suspect a slab leak near you, don't wait. Every day a slab leak runs, it can erode the soil supporting your foundation. Our electronic detection is non-destructive, and we offer same-day diagnostics across the Austin metro.

Slab Leak Detection FAQ
What are signs of a slab leak?
The most common signs are an unexplained spike in your water bill, the sound of running water when nothing is on, warm or hot spots on the floor, cracks in walls or tile, damp carpet, low water pressure in part of the home, or a musty smell near the foundation. If you notice any of these, call us — early detection prevents foundation damage.
How are slab leaks detected?
We use a combination of pressure testing (to confirm which line is leaking), electronic acoustic listening equipment (to hear the leak through the slab), and thermal imaging (for hot-water leaks). Together, these methods pinpoint the leak to within inches — no exploratory demolition needed.
What causes slab leaks?
The most common causes in Central Texas are shifting clay soil that stresses pipes, corrosion of aging copper lines, abrasion from pipe rubbing against concrete or rebar, and the natural expansion and contraction of pipe under repeated temperature changes. Poor original installation can also contribute.
How urgent is a suspected slab leak?
Very. A running slab leak erodes the soil beneath your foundation and can cause structural damage within days. If you suspect one, call us 24/7 at (512) 965-9154 — early detection and repair can save you thousands in foundation damage.
