Slab Leak Detection & Repair
Warm floors, damp carpet, or water running under the concrete? We pinpoint slab leaks within inches — no torn-up floors, no guesswork.
View this serviceFOR BUSINESS OWNERS & PROPERTY MANAGERS
Manage the leak with a plan for the building around it.
A leak in an occupied property involves more than plumbing. Tenant access, business hours and shared water supplies all affect how the work proceeds. Our commercial leak detection in Reno helps owners and facility managers investigate water loss in offices, retail spaces, warehouses and multifamily buildings while accounting for those practical constraints.
Leak Detection Reno coordinates with your site contact to review affected areas, available plumbing records and access requirements. We explain the findings, recommended repairs and any anticipated water shutoffs so you can arrange approvals, notify occupants and plan the next steps with fewer surprises.

The Basics
Commercial buildings run plumbing systems that homes never see: larger domestic mains, hot-water recirculation loops serving dozens of fixtures, risers through multiple floors, long underground runs between buildings, and irrigation feeding parking lots and entries. The stakes scale with them. A slab leak in a single-family home costs the homeowner flooring; the same leak in a occupied suite costs rent, disrupts tenants, and can close a restaurant floor or a hotel wing. That is why commercial leak detection is measured in operating hours saved, not just pipes fixed — and why the diagnosis has to be right the first time.
Reno's property mix brings its own failure patterns. The Downtown and Midtown core stacks hotels, casinos, and restaurants with 24/7 water demand, heavy kitchen lines, and aging mid-century plumbing behind remodeled finishes. South Reno's office parks and medical buildings run tenant-improvement plumbing through big slabs. Sparks adds industrial and warehouse space with long yard lines and site irrigation. Multi-family across Midtown and the UNR area compounds it all with turnover plumbing, aging risers, and units where a slow leak in one suite becomes everyone's problem by the time it surfaces.
Our commercial process is built for exactly that reality. A property manager calls, we triage the system on the phone, and we schedule the survey around your operations — after hours where it matters, immediately when water is moving. On site, we isolate and test with acoustic, thermal, and tracer-gas equipment, pinpoint the failure non-invasively, and mark it before anything opens. Repairs are quoted at a flat rate before work starts, and every job closes with a written report — findings, photos, moisture mapping — formatted for insurance claims, TMWA reviews, and owner portfolios. One call, one point of contact, documentation that holds up in a boardroom.
Commercial Leak Warning Signs
Commercial leaks surface through tenants and invoices before they surface through drywall. Any of these warrants a survey — two or more make it urgent.
The building closed, everything shut down, and the meter still moved — a pressurized system is feeding something nobody can see. Overnight readings are the cleanest evidence.
Musty smells, damp carpet edges, or 'the air feels wet' in an occupied suite are often the first report of a leak that has been running behind finishes for weeks.
Brown rings on acoustic tiles, discoloration along baseboards, paint blistering in common areas — each one maps back to a run above or behind it.
A hot-water recirculation loop that runs constantly or short-cycles is often compensating for a hot-side leak — the equipment is telling on the plumbing.
Site irrigation mains and yard lines leak exactly like residential ones — a perpetually wet planter strip or lawn section on a commercial parcel is a main-line symptom.
When the water line on an operating statement trends up with occupancy flat, the difference is usually a leak — and it compounds every month it runs.

Commercial Leak Detection & Repair is one of nine specialties our Reno crew runs every week — same team, same flat-rate quotes, one 24/7 line for all of them.
Warm floors, damp carpet, or water running under the concrete? We pinpoint slab leaks within inches — no torn-up floors, no guesswork.

View this serviceHow It Works
A sequence designed for occupied buildings: coordinate, isolate, pinpoint, document — with zero guesswork and minimal disruption.
One point of contact, one plan: which systems, which suites, which hours. We schedule after-hours work where operations demand it — 7 days a week.
Meters, risers, recirculation loops, and yard lines are isolated section by section. The failing segment identifies itself before we look for a point.
Acoustic, thermal, and tracer-gas equipment locates the exact failure — marked within inches, including depth — before any surface opens.
Repair options are quoted flat-rate before work begins, and the closeout report — findings, photos, moisture mapping — is built for insurers and owners.
Transparent Pricing
The same published flat rates as our residential work — because 'call for pricing' is exactly how commercial diagnostics get expensive.
| Service | Typical Reno Price | What's Included |
|---|---|---|
| Commercial detection visit | $195–$395 flat-rate | System isolation, acoustic + thermal + tracer-gas pinpoint, marked location, photos, written report |
| Multi-meter & complex sites | Quoted after a quick call | Large campuses, multi-building parcels, and shared-meter properties — scope confirmed before we roll |
| After-hours scheduling | Same flat-rate model | Nights, weekends, and 7-day scheduling quoted before work begins — no open-ended hourly meter |
| Repairs, most types | Flat-rate, quoted on-site | Section repairs, riser and fixture-branch work, yard-line fixes — pressure-tested before we leave |
Procurement note: licensure and insurance documentation is provided with every commercial proposal, and the closeout report — findings, photos, moisture readings — is formatted for insurance claims, TMWA leak-adjustment reviews, and owner-portfolio reporting. One document, every audience.
Get a Firm Quote — Call NowYour Repair Choices
Every occupied building has constraints. You will be shown the viable repair paths with flat-rate pricing and an honest read on downtime for each.
When the failure is accessible and water is active: locate, quote, repair, pressure-test, return the system to service — often within the same visit.
When downtime is the enemy: we stabilize now, schedule the permanent repair for your closed hours — nights or weekends — and finish before doors open.
Multi-suite buildings get a phased plan: isolate the failing run, keep unaffected tenants in service, and repair section by section with notice given.
The Equipment
Four technologies, scaled to bigger systems — the same non-invasive discipline we bring to homes, tuned for risers, slabs, and yards.
Contact microphones and ground plates track leak noise through slabs, risers, and buried mains — the failure announces its own coordinates.
Infrared cameras read temperature deltas across walls and ceilings — hot-side recirculation leaks and spreading moisture mapped before any demo.
A safe hydrogen-nitrogen mix escapes at the break and rises to the surface — the answer for silent leaks under slabs, pavement, and occupied floors.
Valving the system section by section — risers, loops, yard lines — narrows a building-scale problem to one segment before the pinpoint runs.
Understanding Local Leaks
The Truckee Meadows stresses big plumbing systems the same way it stresses small ones — at scale. Four local forces drive most commercial calls.
Long runs through unconditioned spaces — vacant suites, warehouses, parking structures — burst in the same December–February cold snaps that hit homes.
Scale narrows big domestic systems from the inside — recirculation pumps work harder, fittings fatigue, and hot-side runs fail first.
Downtown and Midtown stack mid-century plumbing behind remodels, while Sparks' 2000s growth hits first-generation soil settlement on long yard runs.
100-degree days and cold nights flex exposed runs, and seasonal soil movement shifts underground lines — commercial yards fail at the joints.
