Confirm it's real
A meter isolation test tells us whether water is escaping at all, before anything gets opened.
Leak detection
Hidden Leak Detection — Find It Before It Spreads
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
Do not ignore these signals.
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
Fast triage, then the right repair.
Narrow it down
Pressure testing and fixture-by-fixture isolation shrink the search area.
Mark the spot
We locate the leak as precisely as possible so any wall or slab opening is small and targeted.
Price the fix before we cut
Spot repair, reroute, or repipe — options and numbers first.
Quick FAQ
Before you call.
Do you have to open my walls to find it?
We isolate and locate first, specifically so that any opening is small and in the right place — not exploratory holes.
Does a slab leak mean repiping the whole house?
Not always. Rerouting the affected line is often cheaper and less invasive. We'll lay out both paths with real numbers.
