Leak Detection & Slab Leak Repair

Hidden leaks in walls, ceilings and under concrete slabs are located by S&S Mechanical using pressure testing, acoustic listening and thermal imaging, then repaired with the smallest possible opening. Slab leak options include spot repair or rerouting the line overhead. We serve Reno, Sparks, Carson City and Sun Valley.

Why slab leaks are common here

Many Sparks and Reno homes built from the 1970s through the early 2000s have copper supply lines running under the slab. Hard water, abrasion against rebar and soil movement wear pinholes into that copper over time. The first sign is often a warm spot on the floor or a water bill that jumps for no reason.

Spot repair vs. reroute

If the line is otherwise healthy, we can open a small section of slab and repair the leak. If the copper has multiple weak points, rerouting that line through the attic or walls with PEX is usually the better long-term investment, and avoids breaking concrete again later.

Warning signs of a hidden leak

  • Warm or damp spots on floors
  • Sound of running water when fixtures are off
  • Cracks in flooring or baseboards lifting
  • Mildew odor or new mold growth
  • Unexplained higher water bills
  • Water heater running constantly

Where we provide this service

Leak Detection FAQs

How do you find a leak under a slab?

We isolate the hot and cold systems, pressure-test each line, then use acoustic ground microphones and thermal imaging to pinpoint the leak within a few inches before any concrete is opened.

Does homeowners insurance cover slab leaks?

Many policies cover the cost of accessing and repairing resulting damage but not the pipe itself. We provide documentation and photos you can submit with your claim.

How can I check for a leak myself?

Turn off every fixture and appliance, then look at your water meter. If the low-flow indicator is still spinning, you have a leak somewhere on the system. Call us to locate it.
