The meter's low flow indicator keeps turning with everything shut off
To control the loss, that little triangle or dial moving with no fixture running proves water is escaping somewhere on the supply side.

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.
Your utility sent a high usage or continuous flow alert
As our response moves forward, smart meters flag flow that never drops to zero across a whole day. Those alerts often arrive before any water is visible inside the building.
You can hear a hiss or a rush in one wall
As our response moves forward, 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
To control the loss, 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
To control the loss, 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
For a decisive response, 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 response team adjusts the work to where water traveled, how far the water traveled, and which materials can be saved.
A symptom interview that narrows the system first
As our response moves forward, 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
To control the loss, the main is closed and a pressure gauge is fitted at a hose bib or a laundry connection.
Hot side and cold side separated
To control the loss, 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
For a decisive response, an acoustic listening device and a ground microphone amplify the sound of water escaping under pressure.
Leak noise correlation on long buried runs
To control the loss, 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 response team
Here is how we usually handle leak detection near Washington, DC 20522.
-
1
You report the symptom and what has been ruled out
For a decisive response, 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 control the loss, close every fixture, then look at the water meter and note whether the low flow indicator moves. Report 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
To control the loss, 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
To control 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
For a decisive response, 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 outline the restoration action plan 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 | To keep the work on track, 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 | To keep the work on track, 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 | To keep the work on track, national estimate including line tracing and correlation on a buried run. | $300 to $800 |
| Tracer gas testing where acoustic methods cannot isolate the line | To keep the work on track, national estimate. Used on plastic pipe, low pressure lines and noisy sites. | $350 to $900 |
| Pool or irrigation line leak location | For a decisive response, 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 | As our response moves forward, national estimate added to the detection fee when formal documentation is required. | $100 to $300 |
| After hours or emergency detection dispatch | As our response moves forward, national estimate for nights, weekends and holidays, billed once rather than per hour. | $100 to $400 nationally |
Which system is leaking
For a decisive response, 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
As our response moves forward, if nobody knows where the line runs, tracing has to happen before listening can start. On older properties that is often half the visit.Slab, wall, crawl space or underground
To keep the work on track, 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
For a decisive response, 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
As our response moves forward, 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
To control the loss, 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
As our response moves forward, two or three wrong holes in tile, drywall and flooring exceed a detection fee fast, and the repairs are visible afterward.
A repair aimed at a guess leaves the leak running
For a decisive response, 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
To keep the work on track, 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
To control the loss, 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
Act first by the short explanation. Open a card if you want a little more detail.
What is happening inside the property
As our response moves forward, the first move is deciding which system is losing water: pressurized supply, gravity drain, irrigation, pool plumbing or a heating loop.
Read the explanation
To keep the work on track, 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
To control the loss, a ground microphone on concrete or soil, or a probe against a wall, amplifies it while filtering traffic and machinery out.
Read the explanation
For a decisive response, 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
For a decisive response, the line is drained and charged with a hydrogen and nitrogen mix, safe and non toxic at the concentrations used.
Read the explanation
To control the loss, when nothing can be heard, tracer gas takes over. 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 keep the work on track, 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?
As our response moves forward, 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?
As our response moves forward, 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?
To keep the work on track, 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?
As our response moves forward, 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?
As our response moves forward, 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?
To control the loss, the line is drained and filled with a hydrogen and nitrogen mix, which is a safe, non toxic blend at the dilution used.
