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 Howard uses the same methods utilities and insurance adjusters rely on โ to pinpoint the failure before anything is cut.

No single detection method works for every leak scenario. Our techs are trained on four distinct approaches and select the right tool โ or combination โ based on pipe type, building construction, and leak characteristics.
Most effective on metal pipe under slab or in concrete โ materials that conduct sound efficiently. We establish a clean acoustic baseline by briefly shutting off the house before scanning.
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.
Hidden leaks occur in different locations throughout a property โ each requiring a slightly different detection approach. Here's how we handle the most common scenarios in Howard, WI.
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.
Supply lines between the meter and the structure run underground and are vulnerable to corrosion, ground movement, and root damage. A main supply line leak shows as high meter usage with all interior fixtures off, sometimes with wet ground or sinkholes along the line path. Acoustic detection locates the failure in the buried line precisely enough to minimize excavation footprint โ we mark the surface above the leak so the repair crew opens only the section they need to.
Irrigation system leaks in main supply and lateral runs are found by isolating zones with the irrigation controller and pressure-testing each zone individually. Zone-by-zone testing narrows the failure to the smallest possible section.

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 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 manager's request.
Finding a hidden leak isn't a single step โ it's a protocol that combines water loss confirmation, zone isolation, and targeted detection in sequence.
We start at the meter. All fixtures off, we watch the meter for 10 minutes. Movement confirms active water loss from the supply side. We also check for visible evidence โ stains, soft floors, moisture readings with a moisture meter at suspect wall surfaces.
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."
Within the isolated zone, we deploy thermal imaging first โ scanning walls, floors, and ceilings for moisture anomalies. Then acoustic equipment confirms the specific pipe location and narrows it to the tightest possible point. Tracer gas is added if acoustic results aren't conclusive.
Insurance-formatted reports are available for claims submission at the same standard โ no additional cost.

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.
Ceiling stain in the living room kept coming back despite two drywall patches. Masters Plumbing Service ran the thermal camera and found the wet zone was traveling from a supply line joint 9 feet away, flowing down a horizontal framing member โ explaining why the patch kept failing. They marked the actual pipe location, we opened 8 inches of wall there, and the repair held. No more stain.
Pool was losing 2 inches per day โ more than evaporation. Masters Plumbing Service pressure-tested the plumbing circuit, isolated the issue to the return line, and ran acoustic detection along the line path to find the failure at a union fitting under the decking. Repair required pulling one deck board instead of the exploratory digging another company had proposed.
Our detection technicians are equipped with acoustic, thermal, and tracer gas tools for the full range of leak scenarios found in Howard, WI homes and commercial properties.
