Water Leak Detection in Marietta, GA
Water leak detection is the process of locating hidden plumbing leaks using diagnostic testing before unnecessary walls, floors, concrete, or other surfaces are opened.
An unexplained water bill, damp flooring, the sound of running water, or a meter that keeps moving when everything is turned off can point to a hidden leak. Finding where that water is escaping is the first step toward solving the problem.
Georgia Water Leak Detection provides professional water leak detection in Marietta, Cobb County, metro Atlanta, and nearby areas. We use non-invasive diagnostic methods to locate hidden plumbing leaks behind walls, beneath flooring, under concrete, and underground.
Instead of opening walls or floors just to search for the problem, we test and narrow down the plumbing system first. Once the suspected source is identified, you have a clearer picture of what needs attention and where.

How Can You Tell If You Have a Hidden Water Leak?
Common signs of a hidden water leak include unexplained water usage, a moving water meter when fixtures are off, damp or warm flooring, recurring moisture, reduced water pressure, and the sound of running water when nothing is being used.
Some plumbing leaks are obvious. Others can continue for days, weeks, or longer before water becomes visible.
One of the most useful warning signs is water consumption that does not match your normal usage. If your bill suddenly increases and there is no clear explanation, a hidden leak may be responsible.
No single symptom proves that you have a hidden plumbing leak. Professional testing helps determine whether water is actually escaping and then narrows down its source.
Other signs include:
- A water meter that continues moving when fixtures and appliances are off
- The sound of running or dripping water when nothing is being used
- Damp carpet, flooring, walls, or cabinetry
- Warm areas on a floor
- Musty odors or persistent moisture
- Water stains on walls or ceilings
- Reduced or inconsistent water pressure
- Buckling, lifting, or damaged flooring
- Moisture appearing around the foundation
- Unexplained water outside the property
How Can You Check Your Water Meter for a Possible Leak?
Turn off known water-using fixtures and appliances, then check whether the water meter continues registering usage. Continued meter activity can be a sign that water is escaping somewhere in the plumbing system.
The meter can help tell you that there may be a problem. Professional leak detection helps determine where the problem is located.
Where Do Hidden Water Leaks Commonly Occur?
Hidden water leaks commonly occur in supply lines, pipes inside walls, plumbing beneath flooring, connections and fittings, pipes beneath concrete slabs, and underground water lines.
Where the leak occurs affects how it needs to be investigated.
A visible connection beneath a sink is very different from a pressurized line beneath concrete. Likewise, water appearing near an exterior wall could originate somewhere else and travel before becoming visible.
This is why the location where you see water should not automatically be treated as the location of the leak.
If the suspected line runs beneath your foundation, learn more about our slab water leak detection service.
For buried exterior lines, see underground water leak detection.
How Do Professionals Detect Hidden Water Leaks?
Professional water leak detection can use meter testing, plumbing isolation, pressure testing, acoustic listening equipment, thermal imaging, and other diagnostic methods to narrow down where water is escaping.
The exact testing process depends on the symptoms, property, plumbing layout, and suspected location.
Confirm the Water Loss
Meter and plumbing-system testing can help establish whether unexplained water loss is actually occurring. Confirming water loss helps distinguish a plumbing leak from other possible sources of moisture.
Isolate the Plumbing
Different sections of the plumbing system can be isolated and tested to determine which line or area is experiencing water loss. Narrowing down the system prevents technicians from searching the entire property unnecessarily.
Pressure Test the Lines
Pressure testing checks whether an isolated pressurized plumbing line holds pressure as expected. A loss of pressure can provide evidence that the line is leaking and help focus the investigation.
Use Acoustic Leak Detection
Acoustic leak detection uses specialized listening equipment to identify sounds and vibrations produced by water escaping from a pressurized pipe. Technicians can compare those signals through surfaces that conceal the plumbing to help narrow down the suspected leak location.
Use Thermal Imaging When Appropriate
Thermal imaging uses infrared technology to identify temperature differences that may be associated with certain hidden water leaks. It can provide another piece of diagnostic information, particularly when a hot-water line is involved.
Use Additional Detection Methods When Needed
Some difficult leaks require additional testing. Depending on the situation, tracer gas or other diagnostic equipment may be used to further narrow down a suspected source. The objective is not simply to prove that water is being lost. It is to get as close as possible to the actual source before invasive access is considered.
How We Find Leaks, Step by Step
Finding a hidden leak isn’t guesswork if you do it in the right order. Here’s how we run the job.
Phone triage
Before anyone drives out, we ask what you've noticed: high bill, wet spot, sound of water. That tells us what equipment to bring.
Walkthrough and quick confirmation
We verify the problem is real and figure out whether it's on your side of the line or the utility's.
Isolate the lines
We shut off sections of the plumbing one at a time and pressure test each one, hot and cold, supply and drain. That narrows it to a specific line before we pick up a listening device.
Acoustic listening
Ground microphones and acoustic sensors pick up the sound water makes moving through a line under pressure. A trained ear can tell the difference between a real problem and normal system noise.
Infrared camera
Thermal imaging confirms what the acoustic equipment found by showing temperature differences through flooring, drywall, or concrete.
Tracer gas or correlator, if needed
On the stubborn ones we run a safe tracer gas through the line and track where it surfaces, or use a digital correlator to pinpoint the exact distance to the break.
Mark it and explain it. We show you what we found and walk you through your options before anyone touches a wall or a shovel.
Every step is built around one rule: no exploratory demolition. We don’t jackhammer a slab or tear open a wall to go looking. The equipment tells us where to look first.
Where a Hidden Leak Usually Starts
A leak can start almost anywhere in a plumbing system, and each spot calls for a different approach. Supply lines inside a wall are the most common culprit, along with drain and sewer lines that fail slower and get missed longer. A water heater leaks at the tank itself or at the fittings where the lines connect. Toilets and fixtures waste water at the flapper, the supply valve, or a cracked base.
Shower pans fail underneath the tile, which is why they’re one of the hardest problems for a homeowner to catch. A failed pressure regulator, a bad connection on a whole-house filter, or a cracked sewer pipe under the foundation can all run steadily without ever showing themselves above the floor.
Can a Water Leak Be Found Without Breaking Walls or Floors?
Yes. Many hidden water leaks can be located or narrowed down using non-invasive diagnostic methods before walls, flooring, or other finished surfaces are opened.
That does not mean a damaged pipe will never need to be accessed. If a pipe behind drywall or beneath concrete needs repair, reaching it may ultimately require opening the surrounding material.
The important difference is when that happens.
Professional leak detection allows the plumbing system to be tested before surfaces are opened. If access is necessary afterward, it can be directed toward the suspected problem rather than using demolition as the search method.
For homeowners and property managers, that can mean less unnecessary disruption and a clearer repair plan.
What Is the Difference Between Leak Detection and Leak Repair?
Leak detection identifies where water is escaping. Leak repair addresses the damaged plumbing after the source has been located.
That distinction is especially important when a leak is hidden.
Replacing drywall, flooring, or another damaged material without identifying the plumbing source does not stop the water loss. Likewise, opening several areas to search for a pipe failure can create avoidable restoration work.
The better sequence is to identify the source, determine what failed, and then choose an appropriate repair based on what was actually found.
Georgia Water Leak Detection provides both detection and repair services. When our team performs the repair, the detection fee is waived.
When Should You Call a Leak Detection Specialist?
Call a leak detection specialist when you have evidence of water loss but cannot determine where the water is coming from.
Professional testing is particularly useful when:
- Your water bill has increased unexpectedly
- The meter shows unexplained usage
- You hear water but cannot see a leak
- Moisture keeps returning
- Flooring is damp, warm, buckling, or lifting
- A plumber or property professional suspects a concealed line
- You suspect a leak beneath concrete
- You suspect an underground water-line leak
- You want the source located before walls, flooring, or concrete are opened
The earlier the source is identified, the sooner you can make an informed decision about what needs to happen next.
