"Schan did a great job, very professional. He came out to see what the job was before he gave me a quote. I have a huge crawl space which took some time but he stuck with it to finish it in one day. Now I can breathe easier knowing it's taking care of right. I highly recommend Clean Air Radon Systems."

"We had a radon remediation installed by them in 2021. We've had to replace the fan 2x already- whereas the expected lifetime of a fan is 8-10 years."

"As a first time home buyer, Tim made sure I understood the entire process of mold/air & radon testing and what the results meant. He also gave me great insight on the house as a whole and what to look for while inspecting. He has your best interest in mind during your home buying experience which alleviates some of the stressors that you d otherwise be facing."

"I rarely post reviews. Sidad came out a day after I called about our 9.5 radon level to inspect and tell us about the installation route of his mitigation system in our basement. He returned the next morning, installed the system & our 3rd party test report came back at 0.3 which she said was super low. I can not say enough about Clue Radon and his excellent job! And on top of that he is honest and very kind! BTW I first called 3 well known Radon Companies in Lake and Dupage County and they all said I'd be looking at a 2-3 week wait because they are that busy. Call Clue Radon:)"

"Chuck was thorough, personable, and very helpful. He went above and beyond to give us helpful pointers and information that was beyond the scope of what was required for the inspection. I highly recommend his services!
