"Ross called back within 30 minutes and set up an appointment for the same week at my convenience. He was extremely professional and very easy to work with. He was on time both time he had to be in my home. I had my results in my email within a few hours of him picking up the sensors. I truly appreciate his time and explanations. I would definitely recommend Ross and Boomtown Radon Testing without hesitation."

"Knowledgeable and professional radon specialist. The service was efficient clean and on time and the results were excellent. They answered all my questions and taught me how to properly monitor. Highly recommend them."

"project radon gas very professional work completed on time and very neat"

"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 above. spent over an hour inspecting and testing"

"Radon levels went from about 12 to hovering between 0.4 and 0.1 after about 24 hours. Great work done quick and done well."

"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:)"

"Jose was very professional, on time and thorough. I will definitely use him again."
