Quick answer
- Warm spots on the floor can signal a hot-water slab leak
- An unexplained jump in your water bill is a classic sign
- The sound of running water when everything is off
- Cracks in flooring or a moist/raised area underfoot
When this applies
Act early
A slab leak doesn't fix itself and can undermine your foundation. Early electronic detection means a smaller, targeted repair.
How it works
How detection works
We use acoustic and pressure equipment to pinpoint the leak's location without breaking up the whole slab — so the repair is targeted to the actual failure point.
What to watch out for
Ignoring early signs
A small slab leak left alone wastes water, drives up bills, fosters mold, and can damage the foundation — turning a targeted repair into major work.
