Signs to look for

When to call us for leak detection

As the coordinated steps continue, if you notice any of these problems, call us before water has more time to spread into nearby materials.

The meter's low flow indicator keeps turning with everything shut off

From the first status check, that little triangle or dial moving with no fixture running proves water is escaping somewhere on the supply side.

Your utility sent a high usage or continuous flow alert

With the scene stabilized, 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 the coordinated steps continue, 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

With the scene stabilized, 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 the coordinated steps continue, evaporation accounts for roughly a quarter inch daily in most conditions.

An irrigation zone stays wet after the system shuts down

With the scene stabilized, a cracked lateral or a valve that will not seat keeps feeding one zone continuously.

What happens

How we take command of leak detection

Our incident command team adjusts the work to which materials took on water, how far the water traveled, and which materials can be saved.

A symptom interview that narrows the system first

From the first status check, supply, drain, irrigation, pool and hydronic heating all leak differently and are found with different methods. With the scene stabilized, ten minutes of questions eliminates most of them before a tool comes out.

Meter observation and valve by valve isolation

As the coordinated steps continue, we watch the water meter while closing isolation valves one at a time, section by section.

A static pressure test on the supply system

To keep the incident under control, the main is closed and a pressure gauge is fitted at a hose bib or a laundry connection.

Hot side and cold side separated

With the scene stabilized, isolating at the hot water outlet splits the system in half. As the coordinated steps continue, knowing which half leaks halves the search area before any listening starts.

Acoustic listening at ground and wall surfaces

As the coordinated steps continue, an acoustic listening device and a ground microphone amplify the sound of water escaping under pressure.

Leak noise correlation on long buried runs

To keep the incident under control, a leak noise correlator places sensors at two access points and calculates the leak position from the tiny difference in arrival times.

What to expect

What to expect from our incident command team

To keep the incident under control, here is how we usually handle leak detection near the United States.

1
You let our dispatcher know the symptom and what has been ruled out

To keep the incident under control, 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 our responders arrive

From the first status check, 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

From the first status check, we establish whether this is supply, drain, irrigation, pool or heating. With the scene stabilized, detection methods are system specific, and starting on the wrong one wastes an hour.
On arrival
4
Isolation, valve by valve

From the first status check, sections are closed one at a time while the meter is watched.
First 20 minutes
5
Static pressure test to confirm and size the incident

As the coordinated steps continue, 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

With the scene stabilized, 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 the coordinated steps continue, 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 the coordinated steps continue, we explain the recommended work and price before you approve the job. As the coordinated steps continue, 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	To keep the incident under control, 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	With the scene stabilized, national estimate. With the scene stabilized, 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	With the scene stabilized, national estimate including line tracing and correlation on a buried run.	$300 to $800
Tracer gas testing where acoustic methods cannot isolate the line	With the scene stabilized, national estimate. As the coordinated steps continue, used on plastic pipe, low pressure lines and noisy sites.	$350 to $900
Pool or irrigation line leak location	With the scene stabilized, national estimate. With the scene stabilized, 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	National estimate added to the detection fee when formal incident documentation is required.	$100 to $300
After hours or emergency detection dispatch	As the coordinated steps continue, national estimate for nights, weekends and holidays, billed once rather than per hour.	$100 to $400 nationally

Which system is leaking
From the first status check, a supply line under pressure is the most locatable.
Whether the pipe route is known
As the coordinated steps continue, if nobody knows where the line runs, tracing has to happen before listening can start.
Slab, wall, crawl space or underground
From the first status check, an accessible wall or crawl space is quick.
Pipe material and depth
As the coordinated steps continue, metal pipe carries leak sound well and is easier to hear.
Background noise conditions
From the first status check, traffic, machinery, wind and a busy building all mask the sound of a leak.
Access and what has to be moved
To keep the incident under control, furniture, stored goods, landscaping and finished surfaces all slow the sweep down.

Why timing matters

What can happen when the area stays wet

From the first status check, water can keep moving into nearby materials even when the surface looks dry.

Exploratory demolition costs more than detection

With the scene stabilized, 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

To keep the incident under control, replacing the section somebody suspected is how a stain returns three weeks later.

Every day is billed water and saturated ground

From the first status check, a pressurized leak runs continuously, unlike a drip that only leaks when a fixture is used.

Soil washout undermines slabs and footings

As the coordinated steps continue, a leak under or near a foundation moves soil as well as water.

Helpful service information

What to know about leak detection

With the scene stabilized, start with the short explanation. From the first status check, open a card if you want a little more detail.

What is happening inside the property

To keep the incident under control, 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 the coordinated steps continue, leak detection is a process of elimination, and the tools come last. To keep the incident under control, 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

From the first status check, a ground microphone on concrete or soil, or a probe against a wall, amplifies it while filtering traffic and machinery out.

Read the explanation

From the first status check, acoustics work because pressurized water forced through a small opening makes a steady, characteristic sound.

What may change the work

With the scene stabilized, the line is drained and charged with a hydrogen and nitrogen mix, safe and non toxic at the concentrations used.

Read the explanation

With the scene stabilized, when nothing can be heard, tracer gas takes over. With the scene stabilized, 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?

From the first status check, 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?

From the first status check, they answer opposite questions. As the coordinated steps continue, detection finds where the water is coming from so it can be repaired.

Can you find a leak without breaking anything?

With the scene stabilized, that is the entire point of the service. As the coordinated steps continue, acoustic listening, correlation, line tracing and tracer gas all work from the surface.

How accurate is leak detection?

With the scene stabilized, on a pressurized metal line in reasonable conditions we are often within a foot.

Do you repair the leak too?

To keep the incident under control, no. As the coordinated steps continue, we locate, mark and document, and your plumber makes the repair.

How does acoustic leak detection work?

To keep the incident under control, 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?

From the first status check, the line is drained and filled with a hydrogen and nitrogen mix, which is a safe, non toxic blend at the dilution used.
