Commercial Leak Detection & Slab Leak Repair

The EPA estimates leaks waste more than 6% of a typical commercial building's water — and an under-slab leak can quietly add thousands to a water bill before anyone sees a drop. We locate hidden leaks with acoustic, thermal, and tracer-gas equipment, then repair them with the smallest possible opening.

Find It Without Destroying It

Hidden Leaks, Found and Fixed

Commercial buildings hide their plumbing in slabs, walls, ceiling plenums, and underground supply runs — which means a leak can run for months behind a spiking water bill, a warm spot on the floor, or a musty smell nobody can place. In Fort Worth's expansive clay soils, slab movement makes under-slab copper and aging galvanized lines especially vulnerable, and tilt-wall and pier-and-beam commercial structures each fail in their own ways.

Guesswork demolition is the expensive way to find a leak. We use acoustic listening equipment, thermal imaging, line tracing, and pressure isolation testing to put an X on the floor within inches of the failure before any concrete is cut. Once located, repair options range from a direct access repair to rerouting the line overhead — and where one leak signals a systemic problem, we will tell you honestly whether repiping is the smarter spend.

Detection & Repair Capabilities

Leak Services We Provide

From a single mystery wet spot to a campus-wide water loss audit, we find and fix leaks across every part of a commercial water system.

Acoustic Leak Detection

Ground microphones and correlators hear pressurized water escaping through slab and soil, pinpointing the failure without excavation.

Thermal Imaging Surveys

Infrared cameras reveal hot-water slab leaks, wall leaks, and saturated insulation invisible to the eye.

Line Tracing & Mapping

We locate and map unmarked supply and drain lines — essential before repairs, remodels, or concrete work.

Pressure & Isolation Testing

Sectional pressure testing isolates the leaking zone in complex multi-tenant and looped systems.

Slab Leak Repairs

Precision access through the slab, repair or reroute of the failed line, and a clean structural patch.

Line Rerouting

Where a slab line has failed once, rerouting overhead often prevents the next three failures — we quote both options.

Domestic Water & Irrigation Leaks

Underground service line and irrigation main location and repair across parking areas and landscaping.

Gas Leak Detection Support

Suspected gas odors are handled under our gas line services with electronic detection and code-compliant repair.

Water Bill & Usage Audits

We compare metered consumption against fixture counts and occupancy to confirm — or rule out — a hidden leak.

Early Warning Signs

Signs of a Hidden Leak in a Commercial Building

By the time water surfaces, the leak is old. These earlier signals are what facility teams should act on.

Unexplained Water Bill Increases

A sustained usage jump with no operational change is the single most reliable leak indicator.

Warm Spots on Floors

A localized warm area on a slab floor almost always marks a hot-water line leaking beneath it.

Meter Movement With Fixtures Off

If the water meter spins with every fixture closed, water is leaving the system somewhere.

Musty Odors or Mold Recurrence

Persistent moisture smells in one zone — especially after remediation — point to an active source.

Cracking, Heaving, or Settling

New slab cracks or floor movement can be both a symptom and a cause of under-slab leaks in clay soils.

Sound of Running Water

Hissing or running water audible in walls or floors when the building is quiet deserves immediate investigation.

The FW Commercial Difference

Why Businesses Choose Us

Anyone can find a leak by demolition. Finding it with instruments — and proving the fix with a pressure test — is what keeps the repair small and the disruption smaller.

Locate First, Cut Once

Electronic detection means we open one small section of slab or wall — not a trail of exploratory holes across your facility.

Commercial-Only

No residential work. Our crews, fleet, and parts inventory are built exclusively for commercial-scale plumbing systems.

Master Plumber Licensed

Every job is performed under an active, verified Texas Master Plumber License with $2M+ insurance coverage.

Upfront Written Pricing

Camera-verified diagnosis and a written estimate before work begins. No hidden fees, no surprise invoices.

Leak Detection FAQ

Common Questions About Leak Detection

How accurate is electronic leak detection?
On pressurized water lines, acoustic correlation and thermal imaging typically locate the failure within a few inches to a couple of feet, depending on pipe depth, material, and background noise. That accuracy is the difference between cutting one two-foot square of slab and trenching a room. We verify every located leak with a pressure test after repair before we close anything up.
What causes slab leaks in Fort Worth commercial buildings?
The dominant local factor is expansive clay soil. Seasonal moisture swings move slabs enough to stress the copper and galvanized lines running beneath them, and decades of that movement causes abrasion wear and joint failures. Add in original-construction pipe reaching end of life in buildings from the 1960s through 1980s, water chemistry, and electrolysis around other buried metals, and under-slab supply lines become the most failure-prone runs in many properties.
Should we repair a slab leak or reroute the line?
If it is the line's first failure and the rest of the run tests sound, a direct repair is usually the economical choice. If the same line has failed before, or detection shows generalized wall thinning, rerouting overhead or repiping the affected zone costs more today but ends the cycle. We price both and give you our honest recommendation — repeat slab penetrations cost more than one decisive fix.
Can you find leaks in underground service lines across a parking lot?
Yes. We trace the line's path, then use acoustic ground microphones and, where needed, tracer gas to locate the failure under pavement. Most service line leaks are then repaired through a single saw-cut access pit rather than an open trench, and we coordinate any required city involvement at the meter or tap.
Do you provide documentation for insurance or owner approval?
Every detection job can include a written findings report: location method, evidence (thermal images, meter test results), the located failure point, cause assessment, and itemized repair options. Property managers use these for insurance claims, owner capital approvals, and tenant cost allocations.
