Price range: $$
Rating: 4.9

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 Dayton, MN to locate leaks without speculative demolition.

Our Detection Methods

The Tools Behind Accurate Leak Detection in Dayton, MN

A pressure test tells us a leak exists and how much water is escaping. Detection equipment tells us precisely where.

🎙️

Acoustic Ground Microphone

Acoustic detection is most effective on metal pipe (copper, cast iron) under slab or in concrete — materials that conduct sound efficiently. It works in quiet environments and requires shutting off the house briefly to establish a clean acoustic baseline.

🌡️

Infrared Thermal Camera

Active water leaks — hot or cold — create a temperature differential on the surfaces they contact. An infrared camera shows these differentials 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 blue-gray cool zone; a hot water leak shows the inverse.

📉

Pressure Decay Testing

We isolate the supply system, pressurize it to operating pressure, and monitor pressure over a timed hold period. Any pressure drop confirms active water loss from the supply side. By isolating zones — hot side vs. cold side, section by section — we narrow down which branch of the supply system is leaking before the detection phase begins.

💨

Tracer Gas Detection

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.

What We Locate

Hidden Leak Types We Find and Document

Hidden leaks occur in different locations throughout a property — each requiring a slightly different detection approach. Here's how we handle the most common scenarios in Dayton, MN.

Under Slab

Slab Leak Detection

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.

In-Wall

In-Wall & Ceiling Leak Detection

We document the thermal anomaly, mark the approximate pipe location, and recommend a minimal access cut rather than a wide wall opening.

Water Main

Underground Supply Line Detection

Supply lines between the meter and the structure run underground and are vulnerable to corrosion, ground movement, and tree root damage. A main supply line leak shows as unusually 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.

Pool & Irrigation

Pool Line & Irrigation Leak Detection

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

Commercial Property Leak Detection

Multi-story buildings, commercial kitchens, retail spaces, and industrial properties have complex pipe networks where a supply or drain leak can go undetected through multiple floors before surfacing. We approach commercial detection systematically — zone by zone pressure isolation, thermal scan of suspect surfaces, and acoustic confirmation.

Documentation

Leak Detection Report for Insurance

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.

Our Process

From Water Bill Spike to Confirmed Leak Location — 4 Steps

Finding a hidden leak isn't a single step — it's a protocol that combines water loss confirmation, zone isolation, and targeted detection in sequence.

Initial Water Loss Confirmation

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 any visible evidence — water stains, soft floors, moisture readings with a moisture meter at suspect wall surfaces.

Zone Isolation & Pressure Decay

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."

Detection Equipment Deployment

We document findings with thermal images and note detection readings at multiple grid points to triangulate the strongest signal.

Written Report & Repair Options

You receive a written detection report including pressure test results, detection method summary, leak location (described relative to fixed reference points), and thermal imagery. If you want us to repair the leak, we quote the repair and execute immediately. If you have your own plumber, the report gives them everything they need.

Customer Reviews

Real Leak Detection Reviews from Dayton

★★★★★

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.

— C. Thornton, Dayton

★★★★★

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 and flowing down a horizontal framing member — 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.

— B. Osei, Dayton, MN

★★★★★

Pool was losing 2 inches of water per day — more than evaporation could explain. 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. Excellent, focused work.

Common Questions

Leak Detection Questions We Answer in Dayton

Secondary indicators: water stains appearing or recurring in the same area without an obvious source; mold or mildew smell in rooms without a plumbing fixture; soft or discolored flooring; consistent sound of running water in walls when all fixtures are off.

The repair itself requires physical pipe access, which typically means a small, targeted opening. But that's a completely different proposition from opening large wall sections while searching for an unknown leak location.

For leaks in plastic pipe, low-pressure situations, or high-noise environments, accuracy may be lower and tracer gas becomes the preferred supplemental method.

We can provide supplemental information to claims adjusters on request, including equipment calibration records and a technical description of the detection methodology used.

We don't rush the detection protocol. The acoustic hold time and thermal scan coverage determine accuracy — cutting them short to save time produces uncertain results that cost more to act on.

Yes — and for most residential leaks, we can repair the failure the same day detection confirms the location. Our service trucks carry the repair materials for the most common supply line failures. We quote the repair as a flat-rate job separate from the detection fee, and you decide whether to proceed with us or take the detection report to your own plumber.
