A tech comes out, runs a real diagnostic, and shows you exactly where the leak is and what it takes to fix it.
Same-day dispatch is available most days: call (470) 454-5051 and we’ll get someone headed your way.
Signs of Hidden Leaks in a Marietta Home
Most water leak trouble doesn’t announce itself. It shows up as a string of small things that don’t add up, until your water bill does the talking.
- Your water bill jumped and nobody in the house changed their habits.
- The dial outside keeps spinning with every faucet, toilet, and appliance turned off.
- You hear running water somewhere in the wall or floor when nothing is on.
- A spot on the floor stays warm or damp for no reason.
- A musty smell shows up in a room with no obvious source.
- Mold appears on a wall or under a cabinet with no plumbing nearby.
- Water pressure drops for no reason you can point to.
- A stain spreads across a ceiling or down a wall.
There’s a fast way to confirm you have a real problem before you call anyone. Shut off every fixture and appliance that uses water, then watch the meter for a few minutes. If the dial is still spinning or the digital reading is climbing, water is going somewhere it shouldn’t.
Early detection matters more than people expect. A pinhole today is a soaked subfloor in six months, and the longer it runs, the more of the bill goes toward drywall and flooring instead of the pipe itself.
What's Causing Leaks in Marietta Homes
Galvanized & copper lines
A lot of what we find comes down to age. Homes built with galvanized pipe corrode from the inside out, and older copper lines develop pinholes where the metal has thinned. Neither one gives much warning before it lets go.
High water pressure
High water pressure is another one we see constantly. If the pressure regulator failed or was never installed, the extra force stresses every joint in the system, and joints are where leaks start. Bad original installation does the same thing, just faster.
Georgia's red clay soil
Georgia’s red clay soil is part of the story too. It swells when it’s wet and shrinks hard when it dries out, and that movement shifts the ground under a house. Lines running under a slab take the strain, and cracks in the concrete follow. Cobb County has plenty of homes old enough to carry more than one of these risk factors at once.
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.
Commercial and Multi-Unit Buildings
Leaks aren’t only a homeowner problem. A restaurant can lose water for months through a slab crack under the kitchen, since the floor never dries with all the foot traffic and mopping. Apartment and condo buildings bring a different headache: trouble in a shared wall can affect more than one unit, and a property manager needs to know which line is failing before anyone opens drywall. Our commercial services run the same non-invasive process on a commercial building as on a house, just with more lines to isolate.
What Happens After We Find It
Finding it is half the job. Once we mark the leak location, we walk you through what it takes to fix it: patch the section, run a new pipe, or a full replacement depending on what we found.
We do the repair in-house. You’re not stuck calling a second company to finish what we started, and you’re not paying two separate service call fees for one problem. If we handle the repair, the detection fee is waived, so the diagnostic work doesn’t cost you extra on top of the fix.
Our technicians are licensed and insured, and every repair follows the same non-invasive-first mindset as the diagnostic. Catching things early is also what keeps a small fix from turning into water damage across a room.
Whole-Home Leak Detectors and Smart Monitoring
Detection catches a problem after it’s already started. Some homeowners want something watching in between visits, and that’s what whole-home leak detectors are built for.
Whole-home systems
These systems sit at the main water line or at specific fixtures and watch for anything unusual: continuous flow when the house should be quiet, a sudden pressure drop, or moisture where there shouldn't be any. A sensor under the water heater catches a slow drip before it ever reaches the drywall. Placement is the whole game: a device tucked in the wrong corner of a utility closet won't catch a failure happening ten feet away. We install these as a standalone upgrade, and we often recommend leak detectors for a house that's already had one problem. Once it's in place, it ties into your smart home app, so the alert reaches you no matter where you are.
Smart leak sensors
Smart leak sensors handle the small stuff too, placed under a sink, behind a toilet, or near the washing machine. They send an alert straight to your phone the moment one gets wet. Some setups go a step further and add an automatic shutoff: if a sensor catches a problem overnight or while you're out of town, the setup closes the supply line itself instead of waiting on somebody to notice standing water. Not every home needs this level of coverage. If your plumbing is newer and you've never had a problem, catching it when something actually goes wrong is usually enough. If you travel often or you've already had a problem once, these systems earn their keep fast.
Why Homeowners Call Us First
Detection and repair, one roof
A lot of outfits locate the problem and hand you off to someone else to fix it, which means two visits and two markups. We do both, so the person who diagnosed it is the same person standing behind the repair.
Non-invasive equipment first
Acoustic sensors, thermal cameras, and pressure testing come out before anyone talks about cutting into a slab. If a job can't be solved without some demolition, we say so upfront.
Open seven days a week
With evening hours, because plumbing problems don't wait for a weekday. Senior and military discounts are available.

Leak Detection FAQs
Here’s what people ask us most about hidden leaks, straight answers first.
It depends on how hard the problem is to reach. Most water leaks behind accessible drywall cost less to track down than ones buried under a sewer line or spread across several yard lines, since each line has to be isolated and tested on its own. If you have us handle the repair, we waive the detection fee.
With non-invasive equipment instead of digging or guessing. Acoustic sensors and ground microphones pick up the sound of water moving through a pressurized line, infrared cameras show temperature differences through flooring or concrete, and pressure testing narrows down which line is losing water. That’s how we find leaks without opening a wall first.
The fastest way is a simple water-off test: shut off every fixture and appliance, then watch your usage for a few minutes. If it’s still climbing with nothing running, water’s going somewhere it shouldn’t. Pinpointing the exact spot without tearing into anything takes the right equipment.
Most jobs take one to two hours from arrival to a marked spot, though something straightforward behind an accessible wall can be faster, and a slab or underground job with several lines to isolate can take longer. Access is the biggest factor. We’ll give you a realistic estimate once we see the property.
Yes, that’s the whole point of the equipment we use. Acoustic sensors, ground microphones, infrared cameras, and pressure testing let us pinpoint the source without any exploratory demolition. We only open up once we know exactly where to dig or cut, and usually that’s a small, targeted spot.
