"great, from the first visit from Bruce to evaluate my radon problem, giving me suggestions & an estimate, everything went smoothly. They did the work today 8/9. I had other companies give me a quote & they did not compare with Radon Technology. Very professional & courteous. I would highly recommend them"

"They came back and checked on it when the levels weren't quite what they should be. I only have good things to say about them. They were very professional and knowledgeable. They seemed to have a lot of information about radon and how to have it removed from our house, and keep the levels down. The price was reasonable."

"I could not be happier with this company. They did the work right away, even working on the weekends.
