What Does A Slab Leak Actually Sound Like?
This is the exact sound signature our acoustic equipment listens for — press play and hear the difference for yourself.
Healthy Pipe Flow
Steady, low, consistent — normal water movement through an intact line.
Pressurized Leak Hiss
A higher-frequency, continuous hiss — the sound of water escaping under pressure.
Synthesized audio approximation for educational purposes. Real acoustic detection uses calibrated listening equipment far more sensitive than the human ear alone.

What homeowners ask before calling
Watch for a rising water bill with no change in usage, a water meter that keeps moving with everything off, warm spots on the floor, or the sound of running water when no fixtures are on. Any one of these is worth a professional diagnostic.
In most cases, yes. Acoustic, electronic, and thermal detection let us narrow the leak to a small, specific area before any concrete or drywall is opened — which is the entire point of diagnosing before repairing.
Most residential leak detection visits take one to a few hours depending on the size of the home, the type of leak, and how accessible the plumbing is. We'll give you a time estimate up front.
It depends entirely on your specific policy. We can't make coverage promises, but we can provide clear diagnostic findings and documentation to bring to your insurance company. See our Insurance Resource Center for more.
A spot repair fixes a single, accessible leak. A reroute avoids a problem section of pipe entirely. Whole-house repiping replaces the system when age or repeat failures make that the smarter long-term option. We'll walk you through which fits your situation after diagnosis — never before.
