I have been using thermal imaging for over two years and glad I do. I have found more plumbing leaks, roof leaks, and water intrusion that would not have otherwise been found during an inspection. Of course, it would have been found after the client moved in.
All I want is happy clients and if I miss something like this, then my clients aren’t happy. There is no reason not to spend $2,000 and get a thermal imaging camera.
