A homeowner in Fresno called us last fall after the third plumber had left her house.
Previous contractors cut holes in ceilings and walls without finding the leak. We used acoustic detection and thermal imaging to locate a pinhole in a copper line with almost no damage.
This is the difference professional leak detection makes.
What Makes Leak Detection Different From Plumbing Repair
A repair plumber is trained to fix what they can see. A leak detection specialist is trained to find what cannot be seen.
Detection requires specific equipment — acoustic amplifiers, thermal cameras, tracer gas systems — and the discipline to gather evidence before opening surfaces.
