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 Hollywood 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.
Pressure decay testing is the standard by which we confirm a leak is present before committing detection equipment time. A rapid drop vs. a slow one also indicates the approximate size of the escape point.
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.
Supply lines running under or through the concrete slab fail from corrosion, shifting, or manufacturing defects โ and 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. Confirmed slab leak location is documented with marked coordinates for the repair crew.

We document the thermal anomaly, mark the approximate pipe location, and recommend a minimal access cut rather than a wide wall opening โ typically saving hundreds in drywall repair costs.
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 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.
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."
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.
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 Hollywood, FL homes and commercial properties.

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