Colorado Radon Institute, which also goes by the names Homedics, Mico Environmental, Eco Depot, etc - all run by Mike Merit. He has been DE-certified (even though he claims otherwise) and is known for very shoddy work that isn't to code - as bad as not even drilling the pipe into the floor, just gluing it on! I sued him for not completing his work and not honoring his fake 10 year warranty when the work he *did* complete failed after just 2 weeks. I won but won't see any money. He continually changes company name and banking location so as not to be found. I wish I'd checked online before hiring him. Be warned!
