The difference between a $300 pipe repair and a $3,000 drywall-and-remediation job is often just whether the leak was found before or after excessive wall opening. Our detection service in Saint Marys uses the same methods utilities and insurance adjusters rely on โ to pinpoint the failure before anything is cut.

A pressure test tells us a leak exists. Detection equipment tells us precisely where.
Pressurized supply line leaks create a low-frequency sound as water escapes the pipe and contacts surrounding soil or structure. Our amplified listening devices filter background noise so we can triangulate the loudest point โ often to within 6โ12 inches of the actual break, through concrete slabs or behind drywall.
Active water leaks create temperature differentials on the surfaces they contact. An infrared camera shows these as color-coded heat maps, revealing the wet zone inside a wall or under a floor without any cutting. A cold water leak behind drywall appears as a spreading cool zone; a hot water leak shows the inverse.
We isolate the supply system, pressurize to operating pressure, and monitor over a timed hold period. Any pressure drop confirms active water loss from the supply side. By isolating zones โ hot side vs. cold side, section by section โ we narrow down which branch is leaking before deploying detection equipment.
For leaks that don't produce sufficient acoustic signature โ very slow leaks, polyethylene pipe, or leaks deep under concrete โ we 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. Sensitive to concentrations far below what produces an audible acoustic signal.
Our detection service covers the full property, not just the obvious locations.
Thermal imaging supplements acoustic detection for slab leaks, identifying the thermal anomaly that appears on the floor surface as water migrates through the concrete.

Wall and ceiling leaks are often traced by following a visible stain to its apparent high point โ but visible damage can be several feet from the actual pipe failure due to how water travels down framing members. Thermal imaging reveals the wet zone accurately, and acoustic equipment confirms the pipe location within the wall cavity.
We also perform leak correlation surveys for longer line runs, using two listening points to triangulate the failure location mathematically.
Pool plumbing โ suction and return lines buried between the equipment pad and the shell โ develops leaks at fittings or in the pipe body that show as unexplained water loss. We pressure-test the pool plumbing circuit, isolate return and suction lines separately, and use acoustic detection to find which line and where.

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.
Commercial buildings have complex pipe networks where a supply or drain leak can go undetected through multiple floors before surfacing. We approach commercial detection systematically โ zone-by-zone pressure isolation, thermal scan of suspect surfaces, and acoustic confirmation.
Here's exactly how a Masters Plumbing Service leak detection call plays out in Saint Marys, GA.
This step confirms we're looking for a real leak rather than a meter error or normal appliance cycling.
Zone isolation 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.
You receive a written detection report including pressure test results, detection method summary, leak location relative to fixed reference points, and thermal imagery. If you want us to repair the leak, we quote immediately and can execute same-visit.

High-efficiency home with a slow leak โ about 1.5 gallons per hour. The tech used tracer gas after pressure testing confirmed the loss but acoustic detection couldn't localize it clearly. Gas detection found the escape at a micro-fitting under the slab in the utility corridor. Impressive work for a very difficult leak to find.
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 with elevated water costs for six months. Masters Plumbing Service ran 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.
