Slab Leak Detection & Repair in Marietta, GA
A leak under the foundation is one of the more expensive problems a Marietta homeowner can put off. We locate slab leaks electronically and repair or reroute the line, matched to what's actually under your specific slab.
Signs you need Slab Leak Detection in Marietta
A warm spot on the floor
A hot water line leaking under the slab warms the surrounding concrete, often the first sign a homeowner notices.
A sudden spike in the water bill
The meter keeps running even with every fixture off, a strong sign of a leak somewhere in the system.
The sound of running water with everything off
A hissing or running sound with no fixture in use often points to a slab leak specifically.
Cracks in flooring or baseboards
Water pressure building under a slab can, over time, cause visible cracking in tile or at baseboard trim.
Spot Repair vs. Reroute
| Spot Repair | Reroute | |
|---|---|---|
| Concrete opening | A small, targeted section | None, or minimal |
| Best for | A single, precisely located leak | Avoiding slab demolition entirely |
| Typical cost | Lower | Can be higher due to added pipe length |
| Restoration needed | Flooring/concrete patch at the opening | Minimal, if the new line avoids the slab |

Why this happens in Marietta
Slab leaks are the single most common serious plumbing issue we see in Marietta's 1970s-90s subdivisions, where copper supply lines were run directly through the concrete slab and are now 30 to 50 years old. That construction method, standard for the era, means a failing pipe leaks directly into or under the foundation rather than into an accessible crawlspace.
How we find the actual problem
We use acoustic equipment to listen for the sound of water escaping under pressure and thermal imaging to spot the temperature difference a hot water leak creates in the slab. Together, these narrow the leak's location before any concrete is touched.
Finding the Leak Without Breaking the Whole Slab
The instinct with a suspected slab leak is to assume the whole floor has to come up to find it. In practice, electronic leak detection narrows the location to a small area first, so any concrete that does get opened is targeted to that specific spot rather than a guess.

Slab Leak Detection FAQ
A slab leak usually comes with a water-related symptom, a rising bill, a warm spot, or the sound of running water, rather than the cracking-only pattern typical of foundation settling. We can help you tell the difference over the phone before scheduling a visit.
Often the water damage caused by a slab leak is covered, while the plumbing repair itself may or may not be, depending on your specific policy. We can provide documentation of what we find, but coverage questions go through your insurer.
No. A slab leak gets worse over time as the surrounding concrete and soil continue to erode from the escaping water, which is why we treat a confirmed slab leak as something to address promptly rather than monitor.

What to do while you wait
Shut off the main water valve
If the leak is active rather than a slow seep, shutting off the main stops the water loss and limits further erosion of the concrete and soil around the leak while you wait.
Don't attempt to break into the slab yourself
Opening concrete without first locating the leak electronically often misses the actual source and can damage structural elements unnecessarily.
Note when symptoms started
A warm spot's exact location, when a water bill spike began, or when a sound was first noticed all help narrow down the leak before equipment is even used.
Watch for water reaching electrical outlets or systems
If water from the leak reaches an outlet or appliance, treat it as an electrical safety concern and shut off power to that area at the breaker if it's safe to do so.
