Slab Leak Detection and Repair in Atlanta
Think you have a leak in the floor? Warm spots, a water bill that jumped overnight, or a damp patch that will not dry usually means water is escaping under the slab. Plumbing Express finds the leak first, confirms the location, and walks you through your options before anyone breaks concrete.
Signs you may have a slab leak
Since 1989, Plumbing Express has helped thousands of Georgia homeowners with slab leaks and whole-house repipe in Atlanta projects. If you are noticing any of these signs, call us at (404) 236-6535 for a free in-home estimate. You can book any hour; service runs during service hours.
Common signs of a slab leak include:
- Warm floor spots over a hot water line
- Water pooling outside the foundation
- A tankless or water heater that never seems to shut off
- A water bill that jumped without more usage
- A musty smell with no obvious source
- Damp or wet flooring with no visible fixture leak
Left alone, a slab leak can damage floors, walls, and even the foundation. The next step is finding the exact location, not guessing with a jackhammer.

How we find a slab leak
We do not break concrete to go looking. Plumbing Express confirms the location first, then discusses repair or reroute options with you.
- Meter dial check. We watch the meter with everything in the house off. If the dial is still moving, water is escaping somewhere.
- Inside-vs-outside isolation. We isolate the home from the yard line so we know whether the leak is under the slab or on the water service line between the meter and your house.
- Thermal scan. A thermal camera shows warm or cool patterns that point to where water is traveling under the floor.
- Acoustic listening. Sensitive equipment picks up the sound of pressurized water escaping through the slab.
- Gas tracer when needed. Trace gas helps pinpoint stubborn leaks that are harder to hear or see on thermal.
More than one leak is possible. We confirm location before anyone breaks concrete. No exploratory jackhammering.
On one recent Metro Atlanta job, a thermal scan showed an active hot-line leak under the living room. The homeowner chose a whole-house repipe in Atlanta instead of chasing the next hole. Water was restored each evening, and our own people handled the drywall and paint.
Is this a sign of a bigger problem?
Sometimes a slab leak is a one-off. Often it is the first clear sign that the pipe under the slab is already failing. Spot repairs can turn into a cycle: fix one leak, wait for the next, break more concrete, and watch costs stack up.
When the pipe material is failure-prone or you have already had more than one leak, many homeowners go straight to a whole-house repipe in Atlanta. New lines run above the slab through walls and ceilings, so the defective underground pipe is taken out of service for good. See the signs you need a repipe if you are comparing repair versus replace.

What a First Floor or whole-house repipe with Plumbing Express includes:
- Transferable labor and materials warranty
- Turn-key work that includes how we restore drywall and paint in-house with our own people
- Water restored at the end of each workday
- A permanent bypass of the failing slab pipe
- Flexible payment options
Most Metro Atlanta whole-house repipes run about $10,800 to $14,100. The number on your free in-home estimate is the number on the invoice. Free in-home estimates cover repipe, water heater replacement, and water service line work; service and diagnostic visits are separate.
Sudden water damage is often covered by insurance even when the pipe work is not. We are plumbers, not insurance advisors, and we do not file claims. Read more about will homeowners insurance pay for this, then call (404) 236-6535 to schedule.

Frequently Asked Questions
How do you find a slab leak without breaking my floor?
We start with a meter dial check, then inside-vs-outside isolation to confirm the leak is under the slab rather than on the service line. From there we use thermal scanning, acoustic listening, and gas tracer when needed. We confirm the location before anyone breaks concrete. No exploratory jackhammering.
Can there be more than one slab leak?
Yes. More than one leak is possible under the same slab, especially when the pipe material is already deteriorating. That is why we map what we find before recommending a spot repair or a full bypass. Chasing one leak and ignoring the condition of the rest of the line is how the repair cycle starts.
Is a slab leak a sign I need a whole-house repipe?
Not always, but often it is the first clear sign the underground pipe is failing. If the material is failure-prone or you have already had more than one leak, many homeowners choose a whole-house repipe in Atlanta so they are not back under the slab next year. Compare that path with the signs you need a repipe.
What does a free in-home estimate cover?
A free in-home estimate covers repipe, water heater replacement, and water service line work. Service and diagnostic visits are separate. When a repipe is the right path, the number on the estimate is the number on the invoice. Most Metro Atlanta whole-house repipes run about $10,800 to $14,100.
Will homeowners insurance pay for this?
Sudden water-damage messes are often covered even when the pipe repair or repipe is not. Coverage depends on your policy and the cause of the leak. Plumbing Express does not file claims. We are plumbers, not insurance advisors. Review your policy, talk with your carrier, and use our documentation if your adjuster asks for it. More detail is on our leak detection guide.
Why is rerouting better than a spot slab repair?
Rerouting installs new accessible pipe through walls and ceilings and takes the defective underground line out of service. A spot repair patches one hole and leaves the rest of the aging pipe under the slab. When the material is already failing, spot repairs often start a cycle. See what a whole-house repipe costs in Atlanta if you are weighing both paths.
