Slab Leak + Water Heater · Lilburn, GA

Slab Leak Repair and Water Heater Replacement in Lilburn, GA

A warm spot on the laundry-room floor turned out to be a hot-water line leaking under the concrete slab. Thermal imaging pinpointed it, we opened only where needed, repaired the line, and replaced the aging water heater. Stars and Pipes Plumbing Atlanta, MP211014.

Stars and Pipes Plumbing Atlanta locating a slab leak with a thermal imaging camera in Lilburn, GA

The diagnosis

What we found

The heat radiating up through the floor was the tell. Using a thermal imaging camera, we traced it to a pinhole leak in a hot-water line running beneath the slab. Left alone, that constant moisture under the foundation invites structural damage, mold, and a climbing water bill.

The work

What we did

  1. Pinpointed the leak with a thermal imaging camera to keep the opening small
  2. Opened the slab only at the leak and cut out the failed pipe section
  3. Installed new pipe with two solid connections and pressure-tested the repair
  4. Replaced the aging 50-gallon gas water heater
  5. Added a drip pan, a new shutoff valve, and a new thermal coupling
  6. Verified operation and backed the heater with a 6-year warranty

What this job shows

Why early detection is the whole game with slab leaks

Under a concrete slab, a pinhole leak doesn’t announce itself - it just runs, day after day, until the water shows up as a warm floor, a musty smell, or a foundation problem that costs many times what the pipe repair would have. Finding it early, and precisely, is what keeps a slab leak from becoming a structural one.

That’s why we lead with imaging rather than a jackhammer: pinpointing the leak means a targeted slab leak repair instead of an open floor. And since the water heater feeding that line was already past its prime, replacing it in the same visit spared this Lilburn homeowner a second failure - and a second service call - down the road.

Frequently asked questions

How do you find a slab leak without tearing up the floor?

We use a thermal imaging camera and acoustic listening to trace a hot-water slab leak to a small, specific spot before we open anything. On this job the heat coming through the floor let us narrow the leak to a single area, so we opened only where the pipe had failed instead of demolishing the whole slab.

Is a warm spot on the floor always a slab leak?

Not always, but a warm patch on a floor over a slab is a classic sign of a leaking hot-water line underneath - especially paired with a higher water bill or the sound of running water when nothing's on. It's worth checking quickly, because moisture trapped under a slab can reach the foundation and cause far more expensive damage than the leak itself.
