A water bill that jumped 30% with no change in usage. A ceiling stain that keeps reappearing after patches. A soft spot in the flooring with no visible source. These are signs of a hidden leak that's been running long enough to cause structural damage — and every day it runs is money lost and damage accumulating. Masters Plumbing Service uses acoustic ground microphones, thermal imaging cameras, and precision pressure testing in Ogden, NC to locate leaks without speculative demolition.

A pressure test tells us a leak exists and how much water is escaping. Detection equipment tells us precisely where.
Pressurized supply line leaks create a distinctive low-frequency sound as water escapes the pipe and contacts surrounding soil or structure. Our acoustic listening devices amplify this signal, filtered for background noise, so we can walk a grid pattern and triangulate the loudest point — often to within 6–12 inches of the actual break.
Thermal imaging is particularly effective inside insulated wall cavities and for finding the extent of moisture spread beyond the immediate leak point. It tells us not just where the pipe is failing but how far the moisture has already traveled.
Pressure decay testing is the standard by which we confirm a leak is present before committing detection equipment time. It also tells us approximately how significant the leak is — a rapid pressure drop vs. a slow one indicates the size of the escape point.
For leaks that don't produce sufficient acoustic signature — very slow leaks, polyethylene pipe, or leaks deep under concrete — we can introduce a nitrogen/hydrogen tracer gas mixture into the isolated pipe and use a calibrated gas detector at the surface to find where the gas escapes. The detection sensitivity can locate leaks that produce no discernible pressure drop during a standard timed test.
Our detection service covers the full property, not just the obvious locations.
Supply lines run under or through the concrete slab in most slab-on-grade homes. When these lines fail — from corrosion, shifting, or manufacturing defects — the leak is invisible from the surface but audible to acoustic equipment. We walk the floor on a grid pattern, map the loudest detection points, and triangulate to a specific floor location, typically within a square foot.
We document the thermal anomaly, mark the approximate pipe location, and recommend a minimal access cut rather than a wide wall opening.
We mark the ground above the detected leak location so the repair crew opens only the section they need to.
Pool plumbing — suction and return lines buried between the equipment pad and the pool shell — can develop leaks at fittings or in the pipe body that appear as unexplained water loss. We pressure-test the pool plumbing circuit, isolate the return and suction lines separately, and use acoustic detection to find which line and where.
Commercial water loss from undetected leaks often shows up as elevated utility bills for months before physical evidence appears. We can assess a commercial building's plumbing system for suspected leaks at the property owner's or property manager's request.
Insurance claims for water damage from hidden leaks typically require documentation that the leak was not visible or detectable without specialized equipment. Our detection report includes: pressure test results confirming active water loss, detection method used, thermal imagery or acoustic mapping showing leak location, and technician certification information.
Here's exactly how a Masters Plumbing Service leak detection call plays out.
This step confirms we're looking for a real leak rather than meter error or a normal appliance cycling.
Zone isolation is the step that turns "there's a leak somewhere in the house" into "the leak is on the hot side supply, between the water heater and the master bath."
We document findings with thermal images and note detection readings at multiple grid points to triangulate the strongest signal.
Insurance claims: the report is formatted to support a claim for water damage from a concealed leak. We can provide supplemental documentation on request.

My water bill doubled over three months with no change in usage. Masters Plumbing Service came out, confirmed the meter was moving with everything off, isolated the cold supply to the kitchen as the failing branch, and used the acoustic device on the slab to pinpoint a location 4 feet from the outside wall under the kitchen floor. The repair crew opened a 10-inch circle in the tile, found a pinhole in a copper elbow exactly where detection said it would be. I was skeptical acoustic detection was that precise — it was.
Our insurance company required professional leak detection documentation before approving the claim. Masters Plumbing Service's written report with pressure test data and thermal imagery was exactly what the adjuster needed. Claim approved. The detection cost was covered as part of the claim.
Commercial building where water costs were running 40% above baseline for six months. Masters Plumbing Service ran a systematic zone-by-zone pressure isolation across four floors, narrowed the loss to the third-floor kitchen supply branch, and located the failure with thermal imaging at a concealed valve body in the ceiling. No damage to the finished ceiling.

Our detection technicians are equipped with acoustic, thermal, and tracer gas tools for the full range of leak scenarios found in Ogden, NC homes and commercial properties.

Masters Plumbing Service's detection team finds hidden leaks in Ogden homes and commercial properties using equipment that eliminates guesswork. The detection appointment pays for itself the moment it prevents one unnecessary wall opening.
