"Dawn was professional and extremely nice. She arrived at our home on time and returned 2 days later to read the test results. She immediately forwarded these results to us for our records. I highly recommend Radon Tec."

"Mat is the inspector realtors hate... tongue-in-cheek. He is extremely knowledgeable, has great attention to detail, and is very honest. If there is something wrong with the property, you better believe he's going to find it. He takes the time and does a thorough job. I highly recommend him!"

"This is a high quality mold/fungi/fungus testing company, with excellent customer service and follow-up. The phones were picked up on the first call each time, and arranging for an appointment was very easy. They arrived on time, were efficient, informing, and friendly in their work, and brought commercial equipment to perform the test samples. The follow up phone call and email on the test results was good, and they provided a potential remediation plan for us to follow on the test results. The third party lab utilized by them had easy to understand numbers, graphs, and descriptions of what was tested. We will do business with Gardner Services again in the near future, and will recommend them to others."

"They didn't opt for me one of the options another provider offered me. Their responsiveness was very good."

"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:)"

"Their services were good. They didn't go above and beyond, but we were happy with their service. They just kind of inspect the house and then gave us a report. He had a good knowledge. He was here on time."

"Technician explained everything about Radon in terms we could totally understand. He was patient, polite, totally knowledgeable and professional."

"Sidad was professional and he performed the radon test with state of art equipment. The radon test price was reasonable and I am happy to deal with him. I would refer to him for future test."

"Very easy to get an appointment on short notice when I had limited time to get a radon test done in the process of purchasing a home. Their price was also slightly lower than an estimate I'd received from another company, and the technician was more thorough about explaining the process than the other company I considered."

"Great to have radon levels checked."
