What to expect

  • Non-invasive location using acoustic listening, electronic detection, or pressure testing.
  • A report on where the leak is and the repair options.
  • Detection is usually a separate step from the repair itself.

What to check first

  • Ask which detection methods they use and whether detection is credited toward repair.
  • Confirm they locate before they cut — you shouldn't pay for exploratory demolition.

Leak Detection FAQs

What are the signs of a slab leak in a Dallas home?

Warm spots on the floor, the sound of running water with everything off, a jump in your water bill, low water pressure, cracking in flooring, or a musty smell can all indicate a slab leak. Dallas's slab foundations and expansive clay soil make under-slab water line leaks relatively common, so professional leak detection is worth it before any repair.
