  • We had an outstanding experience. Everyone that we worked with – Eric, Shannon and our two installers (sorry, can’t remember their names) were fantastic.

    Peter B. – Montgomery
  • Eric and Shannon from Professional Radon Systems were so easy to work with. Shannon went above and beyond for me since I was out of state. I highly recommend them.

    Susan K. – Oswego
  • Very professional and friendly office staff. Tech was thorough and left the property in great shape. Radon reduced from 30 ppm to under one. Installation looks great. Good company to deal with.

    Thomas L. – Wilmington
  • I was extremely impressed with the professionalism of your company, the punctuality of the crew, their communication regarding what they were going to do, the cleanliness of their work and how well organized they were throughout the job. They also took great care to install the piping in a way that was the least intrusive visually, even though it was a more difficult alternative. Overall this was an excellent experience, and I have already recommended Pro Radon to someone else.

    Perry M. – Glen Ellyn
  • I have dealt with many wonderful service companies in the past but really need to express my thanks to Professional Radon Systems for their service and attention to details. From my first contact with the company, Shannon was professional, knowledgeable and patient as I asked many questions, set up appointments, rescheduled appointments and finally had the installation scheduled. Brandon and John installed the system and took me step by step through what the plan was, what they were doing, the best location for the system, and how the system worked, answering questions and explaining the process so clearly I feel I had a thorough understanding of exactly what was done. When they were finished they cleaned up well beyond my expectations!!! Shannon followed-up after the system was installed and when I had some additional questions, Tom came out to remedy the concern within days of the installation. This was followed-up with another call from Shannon to make sure everything was perfect.

    I am so impressed with the way this entire process was handled from start to finish and would recommend to anyone needing radon mitigation to go no further than contacting Professional Radon.

    Francine M. – Naperville
  • Everyone at Pro Radon was very professional and knowledgeable. Eric, the owner, inspected the property himself and gave us a quote on-site. Shannon in the office was always very prompt and helpful and Brandon who installed the system was very polite and took the time to explain everything when he was done. Overall a great experience! 

    M. Jethmalani – Oak Park
  • After mitigation, [Radon levels] dropped from 8 to .8.

    M. Papahronis – St. Charles
  • Your guys were out to install our Radon Mitigation System on 2/16/17 and I just wanted to let you know that we have retested our radon levels and they have dropped to 0.4 pCi/L (originally were about 15.1)

    Your staff was wonderful – courteous, respectful, thorough and hard working. I appreciate what a wonderful job they did!

    D. Falcone – Geneva
  • They might be the nicest guys in the world – friendly, professional, and efficient. We couldn’t have been happier with their work.

    Michelle L. – Glen Ellyn
  • Brandon and John were the two guys who installed our mitigation system. They were very professional and courteous and organized. Terrific workers.

    R. Monzel – Shorewood

    Stephen S. – Glen Ellyn
  • Hi Eric,

    We had our mitigation system installed this morning and I wanted to take a moment to let you know of the wonderful experience we had. Tom and Dan were on time, kind, respectful and professional! They took the time to explain the options and answer all questions. They were beyond professional and provided the best service we’ve had in awhile. Everything they did was top notch – even calling us m’am and sir. Tom was one the kindest and most sincere people we’ve worked with. (Not to say Dan wasn’t just as nice! We just spoke with Tom more as he was the one who explained the initial plan at the beginning and then again at the end.) Thank you so much for the wonderful experience! We would absolutely recommend your business to any friends who are in need of radon mitigation in the future.

    Jillian H. – St. Charles
  • The staff was very friendly and explained the work in detail before starting so that there were no surprises.

    Doug K. – Carol Stream
  • Installation was very quick and clean! Easy to understand the system and how to monitor it in the future.

    Rich R. – St. Charles
  • Eric was quick to respond to a request for a remediation on very short notice. His ability to perform the job was integral to keeping the transaction together. Thanks.

    Gary B. – LaGrange
  • We found Eric and his crew to be very responsive to our needs and very professional. When we found we needed additional work done due to a home inspection, Eric was there the next day to complete the work so the retest of radon levels could continue on schedule. Thanks to Eric and his team for a job well done!

    N. Pearl – Wheaton
  • Prof. Radon Systems were a pleasure to work with. They showed up on time, were courteous, efficient, and did very nice work. The owner of the business was present and the men working with him were very nice. I felt comfortable having them in my house.

    L. Cox – Naperville
  • Very professional and fit the pipes through existing places, so no extra framing. Thanks again!

    D. Naughton – New Lenox
  • The job was well done and everything was left neat and clean.

    K. Houriet – Glenview
  • Very professional installers and extremely clean work done. Completed in less than 4 hours with no hassle. I should have done this years ago, highly recommended!

    Mark T. – Glen Ellyn
  • The installation design was well thought out and was completed as expected. The system reduced my basement radon level from 5.6 pCi/L down to 0.6 pCi/L.

    T. Butler – Illinois
  • Eric and his team were very well informed about the radon remediation work they were doing. His work was done as promised under a tight deadline so that we could complete our closing on time. I would highly recommend Professional Radon Systems to my neighbors and friends!

    D. Ratzlaff – Willow Springs
  • While evaluating the work needed, Eric patiently explained everything thoroughly. He also took the time to answer other questions that came to me later while I was still in the process of choosing a contractor. Eric also demonstrated an excellent understanding of home construction, which lent itself well in designing a very effective system in our home (from >45 pCi/L down to 0.7 pCi/L).

    K. Schleicher – Warrenville
