I found this site after two Radon tests showed elevated levels of 7.9pCi/L. I filled out the survey and within a day Val emailed me back with system recommendations and several attachments on how to test your soil communication and set up a system. I sent in several emails with more questions and always had a quick response. In return, I purchased all my equipment through this site, where the prices are more than competitive. My post mitigation test just came back at <0.4pCi/L.
