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 leak detection guide 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.
Straight Flush Plumbing can help you find the source and understand every option — before anything gets torn up.
