American Leak Detection uses proprietary equipment developed specifically for non-destructive leak detection. Our methods include acoustic listening devices to detect water movement through pipes and structures, electronic amplification to identify pressure differentials, thermal imaging to locate temperature changes caused by leaking water, and tracer gas testing for underground or enclosed plumbing systems.

We identify the source before any repair work begins. This protects your property and keeps repair costs focused on only what's needed.

Service call pricing varies based on property size, the type of system being evaluated, and your location. American Leak Detection operates through a nationwide network of locations, and pricing is set at the local level. Contact our team for accurate information for your service area.

Repair services are available at some American Leak Detection locations. When you schedule a service call, your local team will confirm what services are available in your area. Whether repairs are offered at your location, the detection service provides a complete picture of the problem so you can make an informed decision about what to do next.

If there is a leak present in your system, we will find it. Our technicians are extensively trained, our equipment is proprietary, and our process is built to confirm the source with precision. If no active leak is found, we will let you know and explain what may be causing the symptoms you're experiencing.
