Slab Leak Detection — Find Leaks Under Your Foundation Before We Repair
Slab leak detection is the first step when you suspect a leak under your concrete slab—whether you’ve seen a high water bill, warm spots on the floor, the sound of running water when nothing is on, or mold and moisture. Leak Repair Florida uses non-invasive leak detection—acoustic sensors, thermal imaging, pressure testing, and water meter checks—to pinpoint the source under your slab without digging up the floor first. We’re at 426 W Robinson St, Orlando, FL 32801 and serve Central Florida, Tampa Bay, South Florida, Space Coast, and Northeast Florida. Once we locate the leak, we explain your repair options—epoxy lining, pipe rerouting, or targeted slab access—so you know the repair cost and scope before we start. 24/7 for emergency slab leak situations when water is flooding or causing visible damage. See our slab leak repair and water leak detection pages for repair and general leak detection services.
Why Slab Leak Detection Comes First
Slab leaks are hidden—the pipe is buried in or under the concrete slab foundation. Guessing where to dig can mean unnecessary demolition, higher repair cost, and more disruption. Leak detection lets us:
- Pinpoint the leak location (often within a few feet) so we only open the slab where needed, or use trenchless repair (e.g. epoxy lining, pipe rerouting) and avoid opening the slab at all in many cases.
- Confirm that the problem is actually a slab leak (and not a drain, main line, or fixture leak) so we choose the right repair.
- Save you time and money—targeted repair is faster and less invasive than exploratory digging.
We use the same leak detection methods for slab leaks that we use for wall, ceiling, and underground pipe leaks—acoustic, thermal, pressure, and water meter—adapted for concrete and foundation conditions.
How We Detect Slab Leaks (Non-Invasive Methods)
We locate slab leaks without digging first:
- Acoustic leak detection — Sensors pick up the sound of water escaping from the pipe, even through concrete. We can often pinpoint the leak within a few feet so any slab opening is small and targeted.
- Thermal imaging — Cameras show temperature differences. A leak under the slab can create a warm or cool spot (especially for hot water lines) that shows up on the image, helping us narrow the area.
- Pressure testing — We isolate sections of the plumbing and watch for pressure drop to confirm a leak and approximate location. That helps us tell slab pipe leaks from main line or fixture issues.
- Water meter test — With all fixtures off, we check if the water meter moves to confirm there’s an active leak and sometimes isolate which part of the system is losing water (e.g. hot side, cold side, main only).
Once we know where the leak is, we recommend the best repair—epoxy lining, pipe rerouting, or targeted slab access—and give you an estimate or upfront pricing. See slab leak repair for repair options and cost ranges.
Signs You Need Slab Leak Detection
- Unexplained high water bill — Usage hasn’t changed but the bill has gone up.
- Water meter moving with all fixtures off — Confirms an active leak somewhere in the system.
- Warm or hot spots on the floor — Often means a hot water line is leaking under the slab.
- Sound of running water when nothing is on — Water escaping from a pipe under the slab or in the wall.
- Wet spots, damp floors, or puddles — Especially on slab foundations or near walls.
- Low water pressure — Can indicate a leak or break in the supply line (including under the slab).
- Mold, mildew, or musty smell — Moisture is getting in somewhere; a slab leak can feed mold growth.
- Stains on ceilings or walls — Water travels; the stain may be below the actual leak, including under the slab.
If you notice any of these, schedule slab leak detection so we can confirm and locate the source. In Florida’s humidity, water under the slab can lead to mold and structural issues—acting quickly matters.
Slab Leak Detection Cost
Slab leak detection cost depends on the time and methods used:
- Basic detection (acoustic, water meter test, pressure test): often $200–$500.
- Full detection (acoustic, thermal imaging, pressure testing, report): $300–$600 or more depending on property size and complexity.
- Detection is often included in the repair when we do both—we locate the leak and then repair it, with one estimate for the full job.
We’ll tell you upfront whether we’re charging for detection only or detection plus repair. We can also provide documentation for insurance when the damage is sudden and accidental.
What Happens After We Locate the Slab Leak
Once we pinpoint the leak, we explain your repair options:
- Epoxy lining — We inject epoxy into the damaged pipe to form a new lining. No excavation; good for single pinhole or small failures. See slab leak repair for details.
- Pipe rerouting — We run new pipe through the walls or ceiling, bypassing the damaged section under the slab. No slab cutting; often done in a day.
- Targeted slab repair — We open a small section of the slab (as small as detection allows), repair or replace the failed section, then patch the concrete.
We give an estimate or upfront pricing for the repair after we locate the leak. Flooring or tile restoration after slab work is often separate; we’ll clarify what’s included.

Frequently Asked Questions
How do you detect a slab leak without digging?
We use acoustic sensors to hear water escaping through the concrete, thermal imaging to see temperature differences from moisture, pressure testing to isolate the leak, and water meter test to confirm an active leak. That lets us pinpoint the pipe and repair with minimal or no slab opening.
How much does slab leak detection cost?
Detection alone is often $200–$600 depending on methods and property size. Detection is frequently included in the repair when we do both. We’ll tell you upfront.
Can you repair the slab leak after you find it?
Yes. Once we locate the leak, we offer repair options—epoxy lining, pipe rerouting, or targeted slab access—and give you an estimate. See slab leak repair for repair options and cost ranges.
How long does slab leak detection take?
Most slab leak detection is completed in a few hours. Complex properties or multiple potential leak areas may take longer. We’ll give you an idea when we schedule.
