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

No single detection method works for every leak scenario. Our techs are trained on four distinct approaches and select the right tool β or combination β based on pipe type, building construction, and leak characteristics.
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 β often to within 6β12 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.
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.
Tracer gas is the method of last resort for the most challenging cases. It adds setup time but finds leaks that acoustic and thermal methods alone can't conclusively locate.
Hidden leaks occur in different locations throughout a property β each requiring a slightly different detection approach. Here's how we handle the most common scenarios in Gray, LA.
Supply lines running under or through the concrete slab fail from corrosion, shifting, or manufacturing defects β 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.

Wall and ceiling leaks are often traced by following a visible stain to its apparent high point β 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.
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.

We format detection reports specifically for insurance submission and provide documentation on our detection equipment and methodology to claims adjusters on request.
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.
Here's exactly how a Masters Plumbing Service leak detection call plays out in Gray, LA.
This step confirms we're looking for a real leak rather than a meter error or normal appliance cycling.
We isolate the supply system into zones β hot side, cold side, individual branches β and pressure-test each to determine which is losing water. This narrows the area of active search before detection equipment is deployed.
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.

My water bill doubled over three months. Masters Plumbing Service 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 copper elbow exactly where detection said it would be. I was genuinely amazed at the precision.
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 β 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.
