Professional Leak Detection in Hillsborough, CA โ€” Acoustic, Thermal & Pressure Methods

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 โ€” 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 Hillsborough homes without speculative demolition.

Why Detection First

4 Detection Capabilities We Bring to Every Leak Detection Call

A pressure test tells us a leak exists. Detection equipment tells us precisely where.

๐ŸŽ™๏ธ

Acoustic Ground Microphone

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.

๐ŸŒก๏ธ

Thermal Infrared Camera

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.

๐Ÿ“‰

Pressure Decay Testing

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.

๐Ÿ’จ

Tracer Gas Detection

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.

What We Locate

Leak Detection for Walls, Slabs, Pools & Irrigation

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 Hillsborough, CA.

Under Slab

Under-Concrete Supply Line Failure Location

Thermal imaging supplements acoustic detection for slab leaks, identifying the thermal anomaly that appears on the floor surface as water migrates through the concrete.

In-Wall

Hidden Pipe Failure Behind Finished Surfaces

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.

Water Main

Underground Supply Line Detection

We also perform leak correlation surveys for longer line runs, using two listening points to triangulate the failure location mathematically.

Pool & Irrigation

Pool Line & Irrigation Leak Detection

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.

Leak Detection Report for Insurance Claims

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

Commercial

Multi-Floor & Large-Property Leak Location

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.

Our Process

Systematic Detection โ€” No Speculative Cutting

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.

1

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 visible evidence โ€” stains, soft floors, moisture readings with a moisture meter at suspect wall surfaces.

2

Zone Isolation & Pressure Decay

We isolate the supply system into zones โ€” hot side, cold side, individual branches โ€” and pressure-test each to determine which is losing water. This narrows the area of active search 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 relative to fixed reference points, and thermal imagery. If you want us to repair the leak, we quote immediately and can execute same-visit.

Hillsborough, CA Homeowners Who Found Their Leak with Masters Plumbing Service

โ˜…โ˜…โ˜…โ˜…โ˜…

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.

โ˜…โ˜…โ˜…โ˜…โ˜…

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.

FAQ

What to Know Before Booking Leak Detection

If the meter test confirms water loss, call us before opening any walls. Our detection equipment locates the failure to within inches in most cases โ€” which means a small, targeted access rather than speculative wall demolition.
In most cases, yes โ€” 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 is minimal rather than speculative.
For leaks in plastic pipe, low-pressure situations, or high-noise environments, accuracy may be lower and tracer gas becomes the preferred supplemental method.
Yes. Our written detection report includes: technician credentials, equipment identification, pressure test methodology and results, detection method description, leak location with reference measurements, and supporting thermal imagery. This is the documentation format most insurance adjusters require to approve a concealed-leak water damage claim.
A standard residential leak detection โ€” confirming water loss, isolating the failing zone, and deploying detection equipment โ€” typically takes 1.5โ€“2.5 hours. More complex scenarios (multi-zone commercial, large properties, very slow leaks requiring tracer gas) can run 3โ€“4 hours.
Yes โ€” for most residential leaks we can repair the failure the same day detection confirms the location. Our service trucks carry 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.
