Confirm it's real
A meter isolation test tells us whether water is escaping at all, before anything gets opened.
Leak detection
A high bill, a warm spot on the floor, a musty smell that won't go away — hidden leaks announce themselves quietly. We isolate them behind walls, under slabs, and around fixtures, then give you repair options.
Signs you need this now
A water bill that jumped with no change in habits
The meter moving when everything in the house is off
A warm spot on the floor (often a hot-side slab leak)
Musty smell, bubbling paint, or mold dots on a wall
The faint sound of water running inside a wall
What we do when you call
A meter isolation test tells us whether water is escaping at all, before anything gets opened.
Pressure testing and fixture-by-fixture isolation shrink the search area.
We locate the leak as precisely as possible so any wall or slab opening is small and targeted.
Spot repair, reroute, or repipe — options and numbers first.
Quick FAQ
We isolate and locate first, specifically so that any opening is small and in the right place — not exploratory holes.
Not always. Rerouting the affected line is often cheaper and less invasive. We'll lay out both paths with real numbers.
