What we do

- Underground pipe leaks
- Slab leak diagnosis
- Gas leak detection
- Pool leak detection
- Shower & tub leak testing
- Water main leaks
- Meter & pressure testing
- Repair & damage restoration
A leak you can't see costs the most.
Household leaks waste nearly 10,000 gallons of water a year on average (EPA WaterSense) — and a pinhole inside a wall can run for months, feeding mold and rot, before the first stain shows up.
Warning signs: a water bill that jumped, the meter spinning with everything off, warm spots on floors, musty smells, or a pool losing more than ¼ inch a day.
Call early. Finding it this week instead of this winter is the cheapest plumbing decision you'll ever make.
FIND + FIX, ONE VISIT
Detection companies find it. We find it and fix it.

How we beat the big chains: "Detection-only companies charge $450 just to shrug. No franchise fees, no commissioned salesmen, no rented subcontractors — that's typically 15–30% under national-brand quotes for the same or better spec. Bring us any written quote and we'll match the scope line by line."
