Tom was amazing. He came on time, incredibly professional, and most importantly he was certified as a MOLD ASSESSOR. He was very clear, informative, and I'd even say entertaining haha. I could attend a lecture from him. Tom, thank you also for being incredibly honest.
RTK has been very good with clear communication, instructions, what they are doing and how they are doing it.
I can't speak for other reviewers but we had a great experience.
