Slab Leak Detection & Repair in Reno, NV
Before opening the floor, find out what needs fixing.
A suspected slab leak raises an immediate question: will the floor need to come up? Locating the affected pipe is the first step toward answering it. Leak Detection Reno investigates plumbing leaks beneath concrete slabs so repair decisions can be based on inspection findings.
We explain where testing points to a leak, whether further checks are needed and how the pipe could be accessed or rerouted. A targeted repair may suit an isolated problem; deteriorated pipework may call for a different approach. You can discuss those choices before deciding how to proceed.

The Basics
What Is a Slab Leak — and Why Is It Serious in Reno, NV?
A slab leak is a pressurized supply-line failure beneath the concrete foundation of your home — on either the hot or cold side. Because the pipe is encased in (or run under) the slab, the water does not announce itself at a faucet: it soaks into the ground beneath your living space, runs for weeks or months, and only surfaces as a warm floor, a creeping water bill, or a foundation problem you can feel. It is the most consequential category of residential leak we handle, because the damage compounds silently in both directions — up into flooring and walls, and down into the soil supporting the slab itself.
Reno homes carry a specific stack of slab-leak risk. Hard Northern Nevada water leaves mineral scale that narrows copper from the inside; freeze cycles work on the slab edge every Sierra winter; much of the city was built from the 1970s through the 1990s with copper runs embedded in concrete that is now 30–50 years into service life; and hillside neighborhoods like Somersett and Caughlin Ranch run elevated static pressure that fatigues fittings around the clock. None of these forces is dramatic on any single day — together, they are why slab leaks cluster on the same streets.
Our approach removes the two worst parts of a slab leak: guesswork and demolition. Acoustic listening, thermal imaging, pressure isolation, and tracer gas locate the failure from the surface — usually within inches. The repair is then quoted at a flat rate before we open anything, most repairs are completed the same visit, and every job includes a written report with photos that insurance adjusters actually accept.
Slab Leak Warning Signs
Signs You May Have a Slab Leak in Your Reno Home
Slab leaks announce themselves quietly. Any one of these signs is reason enough to book a survey — and two or more together make the odds very high.
Warm spots on the floor
A hot-water slab leak warms the concrete above it — noticeable barefoot, especially on tile, and frequently the first thing homeowners notice.
Damp carpet or dark baseboards
Moisture wicking up through flooring or staining baseboards with no spill, pet accident, or weather to explain it.
Water sounds with everything off
Hissing or running water under the floor while every fixture is closed — the classic acoustic signature of a pressurized slab leak.
Pressure that keeps dropping
A supply system losing pressure with no visible fixture leak is usually losing it under the slab instead.
A water bill that jumps
A TMWA bill creeping upward month after month, with habits unchanged, points to a constant hidden loss — often the earliest objective evidence.
Cracked tile or new floor gaps
Long-term moisture and soil movement under the slab can lift tile, open hardwood gaps, or create hollowness along the leak path.

How We Locate and Repair Slab Leaks in Reno, NV
The same disciplined sequence on every job — built to find the leak precisely and keep any opening of the slab small, deliberate, and exactly placed.
- Step 1
Phone triage & meter test
Describe the signs and we confirm the loss with a two-minute meter test over the phone, then dispatch with the right equipment already loaded. Emergencies start with shut-off coaching.
- Step 2
Acoustic & thermal survey
Ground microphones listen through the concrete while thermal imaging maps hot-water paths — together they narrow the failure to a precise point, usually within inches.
- Step 3
Marked leak + written report
The spot is marked, photographed, and explained in plain English. The report is formatted for insurance adjusters if you are claiming the damage.
- Step 4
Flat-rate repair options
Spot repair at the marked point or a reroute when the run is failing more broadly — quoted flat, approved by you, most completed the same visit.
Straight Answers
How Much Does Slab Leak Detection Cost in Reno, NV?
Real numbers, confirmed before we begin — the same transparency on a slab job as on every other service we run.
| Service | Typical Reno Price | What's Included |

| Residential slab leak detection visit | $195–$395 flat-rate | Full acoustic + thermal survey, the leak marked on-site, and a written report with photos |
| Emergency slab leak response | Same flat-rate philosophy | 24/7 live triage with shut-off coaching and a 60–90 minute typical dispatch — quote confirmed before we roll |
| Spot repair at the marked location | Flat-rate, quoted on-site | One small, deliberate access opening exactly at the confirmed failure point — approved by you before we start |
| Reroute or section repipe | Custom flat-rate quote | When a run is failing broadly, we abandon the leaking path and route new line — priced in full before work begins |
Every slab detection visit includes insurance-ready documentation. Most Nevada carriers cover the resulting water damage and often the cost of accessing the leak — our reports exist to make that conversation easy.

Slab Leak Repair Options After We Find the Leak
There is never only one way to fix a slab leak — and the right answer is not always the most destructive one. We quote every viable path.
Spot repair
One small opening exactly at the confirmed failure, the damaged section replaced, pressure tested, and the concrete patched. Best when the run is otherwise sound — common with a single fitting or pinhole failure.
Pipe reroute
We abandon the leaking under-slab run and route new piping through walls, the attic, or along the perimeter. Often the smarter spend when scale has narrowed an entire run — one clean path instead of repeated slab openings.
Section repipe
For systems with repeated failures or badly degraded piping, replacing the affected circuit ends the cycle for good — scoped, priced, and documented with the same flat-rate discipline.
The Equipment
The Equipment That Finds Slab Leaks Without Demolition
Four technologies, deployed together on every slab survey — so the first hole we propose is also the last one.
Ground Microphone Acoustics
Sensitive listening equipment amplifies the sound of water escaping under concrete — narrowing the search from room-scale to a few square inches.
Thermal Imaging
Hot-water slab leaks paint a warm trail across the floor; infrared cameras read that trail through tile, wood, and carpet without touching a thing.
Pressure Isolation
Valving the hot and cold runs section by section confirms which line is losing pressure — cutting the search area in half before we listen.
Tracer Gas
When depth and concrete swallow the sound, a safe hydrogen-nitrogen mix pushed through the line escapes at the break — and we detect it at the surface.
Understanding Local Leaks
Why Reno, NV Homes Develop Slab Leaks
The Truckee Meadows is hard on buried copper. Four local forces explain most of the slab leaks we find — and why they repeat on the same streets.
Freeze cycles at the slab edge
Sierra-winter freezes reach slab edges and pipe entry points first; lines routed near the perimeter take the beating, and one hard cold snap can finish a run that was already fatigued.
Hard water scale
Northern Nevada water is mineral-heavy. Decades of scale narrow copper from the inside, raising pressure at every restriction until the weakest point lets go.
Aging housing stock
Much of Reno was built from the 1970s–1990s with copper runs embedded in the slab — now 30–50 years into service life, exactly the window where failures cluster.
Hillside static pressure
Somersett, Caughlin Ranch, and other high-grade neighborhoods run elevated static pressure that quietly stresses every fitting and joint, twenty-four hours a day.
