Leak Detection & Repair in Gretna, NE

A hidden water leak can run for weeks behind a wall, under a slab, or underground before you see real damage, driving up your bill, feeding mold, and weakening your home. JTM Plumbing & Drain locates and repairs hidden leaks across Gretna and Omaha using non-invasive detection (acoustic listening and pressure testing) so we open only what we have to. We find slab leaks, wall and ceiling leaks, water-line leaks, and underground leaks, and then we fix them.

Serving the metro since 2004, we save you from the costly damage a slow leak causes. Call Gretna (402) 203-6193 or Omaha (402) 933-3690.

Leak services we provide

  • Hidden leak detection: acoustic + pressure testing, minimal opening
  • Slab leak detection & repair: leaks in pipes under the foundation
  • Water line leak repair: service line from the meter to the house
  • Wall, ceiling & floor leak repair
  • Underground & yard leak location
  • Toilet, faucet & fixture leak repair
  • Leak damage prevention: shutoffs and pressure correction

Two leak patterns dominate our metro. In winter, freeze-burst pipes in exterior walls, crawlspaces, and at outdoor faucets are common, often discovered as a wall or ceiling leak when things thaw. Year-round, slab leaks (pipes failing under a concrete foundation) show up in homes with slab-on-grade construction as warm floor spots, foundation cracks, or a spike in the water bill. Both are easy to misdiagnose without proper detection, which is why we locate before we cut. Call the Omaha line at (402) 933-3690.

Gary K.

JTM saved the day when we had a serious leak at our main water line shutoff. They came out the same day, quickly diagnosed the problem, and completely stopped the leak. Extremely professional and efficient.

Frequently Asked Questions

Everything you need to know about our services and process. If you can't find your answer, feel free to reach out to our team.

We use acoustic listening equipment and pressure testing to pinpoint the leak's location first, so we only open the specific spot we need to access, not whole walls or floors.

It's a leak in a water pipe running beneath your home's concrete foundation. Signs include warm spots on the floor, foundation cracks, the sound of running water, and an unexplained high water bill.

Every job is priced individually, so we give you a flat, upfront quote before any work begins, with no surprises. Financing is available through Hearth for larger projects.

Very possibly. A quick check: with all water off, see if the meter is still moving. If it is, you have a leak, and we can locate it.

Yes. A slow leak behind a wall or under a floor feeds mold and rot. The sooner it's found and fixed, the less damage and cost.
