Signs to look for
When to call us for leak detection
As hidden moisture is traced, if you notice any of these problems, call us before water has more time to spread into nearby materials.
Your utility sent a high usage or continuous flow alert
During the watchful inspection, smart meters flag flow that never drops to zero across a whole day.
You can hear a hiss or a rush in one wall
As hidden moisture is traced, pressurized water escaping through a small opening makes a steady high frequency sound.
A strip of lawn is greener or soggier than the rest during dry weather
During the watchful inspection, an underground service line leak waters the ground above it long before it surfaces.
The pool loses more than about a quarter inch a day
As hidden moisture is traced, evaporation accounts for roughly a quarter inch daily in most conditions.
An irrigation zone stays wet after the system shuts down
During the watchful inspection, a cracked lateral or a valve that will not seat keeps feeding one zone continuously.
What happens
How we handle leak detection
Our moisture-tracing team adjusts the work to what got wet, how far the water traveled, and which materials can be saved.
A symptom interview that narrows the system first
To protect nearby materials, supply, drain, irrigation, pool and hydronic heating all leak differently and are found with different methods.
Meter observation and valve by valve isolation
As hidden moisture is traced, we watch the water meter while closing isolation valves one at a time, section by section.
A static pressure test on the supply system
From the first damage clue, the main is closed and a pressure gauge is fitted at a hose bib or a laundry connection.
Hot side and cold side separated
During the watchful inspection, isolating at the hot water outlet splits the system in half. As hidden moisture is traced, knowing which half leaks halves the search area before any listening starts.
Acoustic listening at ground and wall surfaces
As hidden moisture is traced, an acoustic listening device and a ground microphone amplify the sound of water escaping under pressure.
Leak noise correlation on long buried runs
From the first damage clue, a leak noise correlator places sensors at two access points and calculates the leak position from the tiny difference in arrival times.

To protect nearby materials, here is how we usually handle leak detection near Mc Lean, IL.
-
1
You tell us the symptom and what has been ruled out
From the first damage clue, meter movement, a wet spot, a sound, a bill, or a failed pressure test all start the search in different places.
Your call -
2
One check you can make before we arrive
To protect nearby materials, close every fixture, then look at the water meter and note whether the low flow indicator moves.
+10 minutes -
3
The system is identified before any tool comes out
As hidden moisture is traced, we confirm whether this is supply, drain, irrigation, pool or heating.
On arrival -
4
Isolation, valve by valve
To protect nearby materials, sections are closed one at a time while the meter is watched.
First 20 minutes -
5
Static pressure test to confirm and size the loss
As hidden moisture is traced, a gauge on a closed system tells us whether pressure holds, and how fast it falls if it does not.
Next 20 minutes -
6
Line tracing, then the acoustic sweep
During the watchful inspection, we map where the pipe runs, then listen along it with a ground microphone or a wall probe.
Mid visit -
7
Correlation or tracer gas if the sound is not enough
As hidden moisture is traced, long buried runs get a leak noise correlator, and quiet or plastic lines get tracer gas.
As needed
Understanding the cost
What can affect the price
As hidden moisture is traced, we explain the recommended work and price before you approve the job. As hidden moisture is traced, these examples show what may change the estimate.
| Common situation | What the estimate may include | Typical range |
|---|---|---|
| Standard leak detection visit, accessible plumbing, one system | From the first damage clue, national estimate for isolation, pressure testing and an acoustic sweep with a marked location. | $150 to $400 |
| Slab leak location using acoustic listening with thermal screening | During the watchful inspection, national estimate. During the watchful inspection, the common band for locating a leak under a slab on grade. | $250 to $600 |
| Underground water service line leak location between the meter and the house | During the watchful inspection, national estimate including line tracing and correlation on a buried run. | $300 to $800 |
| Tracer gas testing where acoustic methods cannot isolate the line | During the watchful inspection, national estimate. As hidden moisture is traced, used on plastic pipe, low pressure lines and noisy sites. | $350 to $900 |
| Pool or irrigation line leak location | During the watchful inspection, national estimate. During the watchful inspection, pressure testing each line and zone, then locating the failed section. | $300 to $700 |
| Written detection report with photographs for a carrier or a builder | From the first damage clue, national estimate added to the detection fee when formal documentation is required. | $100 to $300 |
| After hours or emergency detection dispatch | As hidden moisture is traced, national estimate for nights, weekends and holidays, billed once rather than per hour. | $100 to $400 nationally |
Which system is leaking
To protect nearby materials, a supply line under pressure is the most locatable. As hidden moisture is traced, drains, irrigation and pool plumbing each need different equipment and take longer.Whether the pipe route is known
As hidden moisture is traced, if nobody knows where the line runs, tracing has to happen before listening can start.Slab, wall, crawl space or underground
To protect nearby materials, an accessible wall or crawl space is quick.Pipe material and depth
As hidden moisture is traced, metal pipe carries leak sound well and is easier to hear.Background noise conditions
To protect nearby materials, traffic, machinery, wind and a busy building all mask the sound of a leak.Access and what has to be moved
From the first damage clue, furniture, stored goods, landscaping and finished surfaces all slow the sweep down.
Why timing matters
What can happen when the area stays wet
To protect nearby materials, water can keep moving into nearby materials even when the surface looks dry.
Exploratory demolition costs more than detection
During the watchful inspection, two or three wrong holes in tile, drywall and flooring exceed a detection fee quickly, and the repairs are visible afterward.
A repair aimed at a guess leaves the leak running
From the first damage clue, replacing the section somebody suspected is how a stain returns three weeks later.
Every day is billed water and saturated ground
To protect nearby materials, a pressurized leak runs continuously, unlike a drip that only leaks when a fixture is used.
Soil washout undermines slabs and footings
As hidden moisture is traced, a leak under or near a foundation moves soil as well as water.

What to know about leak detection
During the watchful inspection, start with the short explanation. To protect nearby materials, open a card if you want a little more detail.
What is happening inside the property
From the first damage clue, the first move is deciding which system is losing water: pressurized supply, gravity drain, irrigation, pool plumbing or a heating loop.
Read the explanation
As hidden moisture is traced, leak detection is a process of elimination, and the tools come last. From the first damage clue, the first move is deciding which system is losing water: pressurized supply, gravity drain, irrigation, pool plumbing or a heating loop.
How the next step is decided
To protect nearby materials, a ground microphone on concrete or soil, or a probe against a wall, amplifies it while filtering traffic and machinery out.
Read the explanation
To protect nearby materials, acoustics work because pressurized water forced through a small opening makes a steady, characteristic sound.
What may change the work
During the watchful inspection, the line is drained and charged with a hydrogen and nitrogen mix, safe and non toxic at the concentrations used.

Common questions
Questions about leak detection
What is leak detection?
To protect nearby materials, it is the service of locating the source of an escaping water leak without demolishing the building to find it.
How is leak detection different from moisture mapping?
To protect nearby materials, they answer opposite questions. As hidden moisture is traced, detection finds where the water is coming from so it can be repaired.
Can you find a leak without breaking anything?
During the watchful inspection, that is the entire point of the service. As hidden moisture is traced, acoustic listening, correlation, line tracing and tracer gas all work from the surface.
How accurate is leak detection?
During the watchful inspection, on a pressurized metal line in reasonable conditions we are often within a foot.
Do you repair the leak too?
From the first damage clue, no. As hidden moisture is traced, we locate, mark and document, and your plumber makes the repair.
How does acoustic leak detection work?
From the first damage clue, water escaping a pressurized pipe creates a steady sound as it forces through a small opening.
What is tracer gas leak detection and is it safe?
To protect nearby materials, the line is drained and filled with a hydrogen and nitrogen mix, which is a safe, non toxic blend at the dilution used.
