Signs to look for

When to call us for leak detection

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

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

Smart meters flag flow that never drops to zero across a whole day. Those alerts frequently arrive before any water is visible inside the building.

You can hear a hiss or a rush in one wall

Pressurized water escaping through a small opening makes a steady high frequency sound. It is one of the most locatable symptoms there is.

A strip of lawn is greener or soggier than the rest during dry weather

An underground service line leak waters the ground above it long before it surfaces. Follow the line from the meter toward the house and look for the anomaly.

The pool loses more than about a quarter inch a day

Evaporation accounts for roughly a quarter inch daily in most conditions. Consistently more than that, especially with the pump off, points to the shell or the pool plumbing.

An irrigation zone stays wet after the system shuts down

A cracked lateral or a valve that will not seat keeps feeding one zone continuously. Irrigation leaks are among the largest and least noticed water losses.

What happens

How we handle leak detection

Our 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

Supply, drain, irrigation, pool and hydronic heating all leak differently and are found with different methods. Ten minutes of questions eliminates most of them before a tool comes out.

Meter observation and valve by valve isolation

We watch the water meter while closing isolation valves one at a time, section by section. When the flow stops, the leak is inside the section we just closed.

A static pressure test on the supply system

The main is closed and a pressure gauge is fitted at a hose bib or a laundry connection.

Hot side and cold side separated

Isolating at the hot water outlet splits the system in half. Knowing which half leaks halves the search area before any listening starts.

Acoustic listening at ground and wall surfaces

An acoustic listening device and a ground microphone amplify the sound of water escaping under pressure.

Leak noise correlation on long buried runs

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 team

Here is how we usually handle leak detection near the United States.

1
You tell us the symptom and what has been ruled out

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

Close every fixture, then look at the water meter and note whether the low flow indicator moves. Tell us the answer when we get there, because it aims the whole visit.
+10 minutes
3
The system is identified before any tool comes out

We confirm whether this is supply, drain, irrigation, pool or heating. Detection methods are system specific, and starting on the wrong one wastes an hour.
On arrival
4
Isolation, valve by valve

Sections are closed one at a time while the meter is watched. Each closure that stops the flow shrinks the search area, often by more than half.
First 20 minutes
5
Static pressure test to confirm and size the loss

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

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

Long buried runs get a leak noise correlator, and quiet or plastic lines get tracer gas. Plastic pipe and low pressure lines are exactly where acoustics run out.
As needed

Understanding the cost

What can affect the price

We explain the recommended work and price before you approve the job. 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	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	National estimate. 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	National estimate including line tracing and correlation on a buried run.	$300 to $800
Tracer gas testing where acoustic methods cannot isolate the line	National estimate. Used on plastic pipe, low pressure lines and noisy sites.	$350 to $900
Pool or irrigation line leak location	National estimate. 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 documentation is required.	$100 to $300
After hours or emergency detection dispatch	National estimate for nights, weekends and holidays, billed once rather than per hour.	$100 to $400 nationally

Which system is leaking
A supply line under pressure is the most locatable. Drains, irrigation and pool plumbing each need different equipment and take longer.
Whether the pipe route is known
If nobody knows where the line runs, tracing has to happen before listening can start. On older properties that is frequently half the visit.
Slab, wall, crawl space or underground
An accessible wall or crawl space is quick. A line under a slab or four feet down in a yard needs correlation, tracer gas or both.
Pipe material and depth
Metal pipe carries leak sound well and is easier to hear. Plastic pipe deadens the noise, which is exactly when tracer gas earns its cost.
Background noise conditions
Traffic, machinery, wind and a busy building all mask the sound of a leak. Some locations genuinely have to be worked at a quieter hour.
Access and what has to be moved
Furniture, stored goods, landscaping and finished surfaces all slow the sweep down. Access is labor, and labor is most of this invoice.

Why timing matters

What can happen when the area stays wet

Water can keep moving into nearby materials even when the surface looks dry.

Exploratory demolition costs more than detection

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

Replacing the section somebody suspected is how a stain returns three weeks later. The second visit costs more than getting it right once.

Every day is billed water and saturated ground

A pressurized leak runs continuously, unlike a drip that only leaks when a fixture is used. Underground, that water is also washing fines out of the soil around it.

Soil washout undermines slabs and footings

A leak under or near a foundation moves soil as well as water. Voids that form there are far more expensive to correct than the pipe ever was.

What to know about leak detection

Start with the short explanation. Open a card if you want a little more detail.

What is happening inside the property

The first move is deciding which system is losing water: pressurized supply, gravity drain, irrigation, pool plumbing or a heating loop.

Read the explanation

Leak detection is a process of elimination, and the tools come last. 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

A ground microphone on concrete or soil, or a probe against a wall, amplifies it while filtering traffic and machinery out.

Read the explanation

Acoustics work because pressurized water forced through a small opening makes a steady, characteristic sound. A ground microphone on concrete or soil, or a probe against a wall, amplifies it while filtering traffic and machinery out.

What may change the work

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?

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?

They answer opposite questions. Detection finds where the water is coming from so it can be repaired. Moisture mapping measures how far the water has already spread so the right materials get dried.

Can you find a leak without breaking anything?

That is the entire point of the service. Acoustic listening, correlation, line tracing and tracer gas all work from the surface.

How accurate is leak detection?

On a pressurized metal line in reasonable conditions we are often within a foot. Plastic pipe, deep burial and heavy background noise widen that.

Do you repair the leak too?

No. We locate, mark and document, and your plumber makes the repair. Keeping those roles separate is what keeps the location honest, because we have nothing to gain from finding it in an expensive place.

How does acoustic leak detection work?

Water escaping a pressurized pipe creates a steady sound as it forces through a small opening. A ground microphone or a wall probe amplifies that sound and filters out background noise.

What is tracer gas leak detection and is it safe?

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