Jonathan was very responsive, helpful and worked with my timeline and budget. He continued to provide value and help me understand the nature of my issue and some steps to take even after the service was over, he still made himself available to assist. Highly recommend.

I recently used Top Tier Testing for mold and soot testing, and I was very impressed with their services. They were professional and very concerned about my well-being.
I highly recommend them for anyone needing reliable air quality testing.
