Leak Detection In NJ — We Find It Without Tearing Your House Apart

Hidden leaks behind walls, underground lines, slab leaks, gas leaks, pool leaks — we isolate the exact spot with pressure testing, meters, and cameras, then open one small section instead of five walls.

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.
Because we're licensed master plumbers, the same crew that locates your leak repairs the pipe, patches what we opened, and stands behind it — no second contractor, no second bill.
Why leak-detection visits end in bad reviews — and our answer
★☆☆☆☆ THE COMPLAINT
“$450 and the guy shrugged: ‘couldn't find it.’”
✓ OUR FIX
We isolate systematically — meter tests, pressure tests line by line, cameras — and you get a written finding either way. No shrugs for hire.
★☆☆☆☆ THE COMPLAINT
“They cut five holes in my walls on a hunch. The leak was in the sixth spot.”
✓ OUR FIX
Testing first, cutting last. We open one small, planned access — where the evidence points — and we patch what we open.
★☆☆☆☆ THE COMPLAINT
“They found it… then told me to ‘call a plumber’ and left.”
✓ OUR FIX
We ARE the plumber. Find and fix, same visit where possible — one crew, one straight price for the whole thing.
PRICE CHECK · NORTH JERSEY 2026
$350 – $3K find + fix
typical fixed-price range
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.
