An unexplained spike on the water bill, a damp patch on the floor with no obvious source, or the faint sound of running water somewhere in the walls — hidden leaks are frustrating precisely because you can't see them. Our Northfield technicians use acoustic and thermal equipment to find them without tearing into walls or floors on a guess.

We use listening equipment and thermal imaging to locate leaks through walls, floors, and slabs without demolition.
Locating the leak precisely keeps any necessary opening small and targeted rather than exploratory.
Our Northfield, IL technicians are trained specifically on detection equipment, not just general plumbing repair.
You'll see or hear the detection results and understand exactly where the leak is before deciding on repair.

These are the hidden leak scenarios we investigate most often across Northfield, IL.
Listening equipment picks up the sound of water escaping under pressure, even through concrete or behind walls.
We narrow a slab leak to a specific small area rather than an entire room.
Thermal imaging is especially effective for detecting hot water line leaks inside walls.
Leaks inside wall cavities are traced to their source rather than just patching the visible stain or damage.
Underground irrigation and pool line leaks are diagnosed with the same precision as household leaks.
We check for common culprits — running toilets, slab leaks, irrigation issues — starting with the most likely first.

A quick call gets a detection specialist scheduled, often same-day.
Our Northfield, IL detection trucks carry the equipment needed for most residential and light commercial leak searches.
You'll understand exactly where the leak is and what fixing it will involve before agreeing to anything.
The identified leak is repaired, or we connect you with our repair team, and the fix is tested to confirm the leak is resolved.
