Quick answer

Professional leak detection uses electronic listening equipment, thermal imaging and pressure tests to find leaks hidden inside walls, ceilings, slabs and yard lines. Pinpointing the exact spot means a small, targeted repair instead of cutting open large sections of your home.

Leak Detection you can count on

A high water bill with no obvious cause, the sound of running water when every tap is off, or a warm spot on the floor are classic signs of a hidden leak. Left alone, even a slow leak wastes thousands of gallons a year and damages framing, drywall and foundations.

Our technicians start with your water meter to confirm a leak exists, then isolate the system to narrow down where it is. Acoustic sensors listen for escaping water, thermal cameras spot temperature changes from hot-water leaks, and pressure tests confirm which line is losing water.

Signs you need leak detection

  • Unexplained spike in your water bill
  • Water meter moves with all fixtures off
  • Sound of running water inside walls
  • Damp drywall, stains or peeling paint
  • Musty smell or visible mold
  • Warm or damp spots on floors

Noticing any of these? Get it checked before it gets worse.

What affects the cost of leak detection?

Leak detection pricing depends on the size of the home, the number of lines to test and whether the leak is inside the house, under the slab or in the yard. Finding the exact location first almost always lowers the total repair cost by limiting how much needs to be opened up.

Leak Detection in Dallas–Fort Worth: local insight

With expansive clay soil and long, hot summers, homes across Dallas–Fort Worth see more hidden leaks than most of the country, particularly in copper lines under slab foundations. If your water utility has flagged unusually high usage, a leak detection visit is the fastest way to find out why.

Answers

Leak Detection FAQs

How do I check for a leak myself?

Turn off every tap and water-using appliance, then watch the water meter for 15 to 30 minutes. If the leak indicator or dial moves, water is escaping somewhere.

Will you have to cut into my walls?

Only at the exact leak location. Accurate detection keeps openings small and repairs simple.

Can you find leaks under the foundation?

Yes. Slab leak detection is one of our specialties, using acoustic and thermal equipment from above the floor.

Is leak detection covered by insurance?

Some policies cover the cost of locating a leak ("tear-out" coverage). We provide documentation for your claim.
