"A small testing device was set up in our basement and was left in place three days. The device was then picked up and we received a phone call a day later informing us of the radon level detected. This was followed up by a professionally prepared report mailed to us detailing the results and how to interpret them."

"Radon Tec worked with me on a reinspection after mitigation. They understood my time demands and that I was living out of state. They completed task on time and on estimate price. Tech even forwarded invoice/results to the closing to give everyone a chance to review documents before closing. I would give a higher rating if I could."

"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."

"Matthew did a great job inspecting the mobile home, and pointed out each step of the inspection as I followed him around. I would definitely hire him again if I needed another inspection."

"David, at Gardner Environmental Services, professionally performed numerous air sample tests inside our home due to a minor smelling of mold in one spot.Fortunately, his lab resource came back with negative results on each location sample David tested. David was reassuring and pleasant to work with. I would recommend his company, to anyone."

"They came to do the repair but I never got a good feeling about it.  They charged a lot for one crack."

"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 Rodriguez was prompt, professional, and fast with results. He was there when he said he would, went there the next day after I called, and provided the results on time. As a real estate professional I know I'll need the services again and I know that he is the person I will be calling. Thank you!"

"He was very good! He discussed with the seller all of what he found in his inspection and was very professional. I will highly recommend him. He's a great guy!"
