“Hi, my name is Greg Batista here to answer another question from the internet.
TechieTom asks: Do those infrared cameras really find hidden leaks?
Yes, but indirectly. Infrared cameras detect temperature differences, not water itself. When moisture evaporates, it cools the surface, creating a thermal signature. Studies by ASTM show infrared scans can detect moisture with 80–90% accuracy when combined with proper testing. Engineers often use them in Florida condos to find hidden leaks behind stucco, roofs, and walls without tearing them open. However, IR scans must be confirmed with other tools like moisture meters to avoid false readings. Used correctly, they’re powerful diagnostic tools that save owners money and disruption.
