Professional Leak Detection in Goffstown, NH — Acoustic, Thermal & Pressure Methods

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

How We Find Hidden Leaks Without Guessing

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

🎙️

Acoustic Ground Microphone

Pressurized supply line leaks create a distinctive low-frequency sound as water escapes the pipe and contacts surrounding soil or structure. Our acoustic listening devices amplify this signal, filtered for background noise, so we can walk a grid pattern and triangulate the loudest point — often to within 6–12 inches of the actual break.

🌡️

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

Tracer gas detection is the method of last resort for the most challenging cases — it adds cost and setup time. We use it when acoustic and thermal methods haven't produced a definitive location and the evidence clearly supports an active leak.

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 Goffstown, NH.

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

Irrigation system leaks in main supply lines 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.

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

We format detection reports specifically for insurance submission and can provide documentation on our detection equipment and methodology to claims adjusters on request.

From Water Bill Spike to Confirmed Leak Location — 4 Steps

Here's exactly how a Masters Plumbing Service leak detection call plays out.

1

Initial Water Loss Confirmation

This step confirms we're looking for a real leak rather than meter error or a normal appliance cycling.

2

Zone Isolation & Pressure Decay

We isolate the supply system into zones — hot side, cold side, and if possible, individual branches — and pressure-test each zone to determine which branch is losing water. This narrows the area of active search significantly before detection equipment is deployed.

3

Detection Equipment Deployment

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

4

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.

What Customers Say About Our Detection Service

★★★★★

High-efficiency home with a leak that defied normal detection. Water loss was slow — 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.

— C. Thornton, Goffstown
★★★★★

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.

— B. Osei, Goffstown, NH
★★★★★

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.

FAQ — What to Know Before Booking Detection

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.
In most cases, yes — the detection phase is entirely non-invasive. We locate the leak using acoustic, thermal, and pressure methods without any demolition. The detection tells us exactly where to open, which means the access opening is minimal rather than speculative.
For pressurized supply lines in concrete or metal pipe, acoustic detection is typically accurate to within 6–18 inches under ideal conditions — quiet environment, no interference from other water use, metal pipe conducting sound clearly. Thermal imaging is accurate to the size of the wet zone it reveals, which varies based on how long the leak has been running and how far moisture has migrated.
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.
The repair quote is given before any wall or floor is opened. You know the full cost of detection + repair before anything is cut.
