Leak Detection

We find hidden leaks in slabs, walls and supply lines before they do real damage.

What It Is

Leak detection finds water escaping where you can't see it: under a slab, inside a wall or along a buried line. Locating it precisely means we open only what's needed to make the repair.

Signs You Need It

  • A water bill that jumps without explanation
  • Warm spots on the floor
  • Damp drywall, peeling paint or musty smells
  • The water meter moving with everything turned off

What To Expect

We start with a meter test to confirm there's a leak, then use electronic listening equipment and cameras to pinpoint it. You'll see where it is and what the repair involves before anything is opened up.

Residential Services

What We Handle

  • Standing water spread across a smooth surface

    Slab Leaks

    A slab leak is a break in a water line that runs under your concrete floor. We pinpoint the spot so the repair is as small and clean as possible.


    What's included

    • Meter and pressure testing
    • Electronic leak location through the slab
    • Repair or reroute options explained
    • Final pressure test

    Common signs you need this

    • Warm or damp spots on the floor
    • Sound of running water under the floor
    • High water bills with no visible leak
  • White vertical pipe running up a gray concrete wall

    In-Wall Leaks

    Pipes inside walls can drip for months before you see a stain. We find the leak from the outside of the wall and open only the area we need to reach it.


    What's included

    • Moisture and acoustic testing
    • Locating the leak inside the wall
    • Small, targeted opening for access
    • Pipe repair and pressure check

    Common signs you need this

    • Stains or bubbling paint on walls
    • Soft or warped drywall
    • Musty smell in one room
  • Tiled utility room with a white sink and exposed pipes

    Fixture & Supply Line Leaks

    Supply lines and shutoff valves under sinks, toilets and appliances wear out over time. We find the drip and replace the worn line or valve before it lets go.


    What's included

    • Checking supply lines and shutoff valves
    • Inspecting toilet, sink and appliance connections
    • Replacing worn lines and valves
    • Leak check after repair

    Common signs you need this

    • Water in the cabinet under a sink
    • Toilet that runs or hisses
    • Corroded or bulging supply hoses
  • Close-up of a camera lens

    Electronic & Camera Location

    Listening equipment picks up the sound of escaping water, and cameras let us look inside drain lines. Together they show where the problem is without guesswork.


    What's included

    • Acoustic leak detection
    • Camera inspection of drain lines
    • Marking the leak location
    • A clear explanation of what we found

    Common signs you need this

    • You know there's a leak but can't find it
    • Water damage with no obvious source
