Quick and easy, very professional, quick results.
Reliable radon was knowledgeable, thorough and friendly. We highly recommend their services to get an accurate reading on your radon levels.
Easy to schedule radon testing and they are on time for pick up and delivery. Will definitely use again and recommend.
The whole process was very easy. They were on time, provided clear instructions about the test and their technician was very polite.
I had a great experience working with Reliable Radon Inspections for a follow up radon test after activating the passive radon mitigation system in our home. They contacted me the day after I submitted my request and were very helpful in explaining the process, answering my follow up questions, and getting me scheduled for drop off and setup of the test the following day. Jim was very friendly and knowledgeable in explaining the necessary procedures to follow during the testing, and the initial setup of the testing devices took less than 10 minutes. The testing process went smoothly and a few days later Jim came by to collect the testing devices and process the collected data. After analyzing the data, Jim provided us a clear and detailed report along with a thorough in-person explanation of our testing results. He also gave us some great insights into the long term management of our radon mitigation system which was very helpful and appreciated. Overall we had a fantastic experience working with Jim and would highly recommend Reliable Radon Inspections Inc!
Fairly priced, friendly and informative. I would definitely recommend Reliable Radon.
The technician showed up on time and called ahead of time, explained everything in great detail, and was easy to work with.
Quick setup, concise instructions, personable interaction. All around great experience.
Jim was really great. Knowledgeable, in and out. Reasonable price. Would highly recommend their services to anyone who needs them.
Jim East, owner and tech doing setup of equipment and testing radon levels in our home was a pleasure to talk to and work with. Full explanation of what to do and not to do during testing period, 48+ hours. Even got a small coffee shop gift card from him.
Jim was very professional! I was so happy to get this task done with some friendly support! Thanks Reliable Radon!!!
Jim is great and was very generous with is time and sharing information. Highly recommend him for all your testing needs.
Jim and his company Reliable Radon are amazing! Very professional- always on time- explains everything! Very knowledgeable. Definitely recommend them! True pleasure working with them.
Professional and knowledgeable. Took his time answering our questions. I am a slight germaphobe. He took his shoes off at the front door without me asking him to remove his shoes! Felt very comfortable with him.
Very professional and informative. Recommend to anyone looking for a great Radon testing company.
I highly recommend this company! Jim helped me understand the testing process, the results and was very informative throughout.
It was a very easy process to schedule and have me house tested. Customer service was great and they explained everything thoroughly. Highly recommend.
Great company! Very effective, they definitely know what they are doing!
Jim was so very kind, knowledgeable and thorough with setup and explaining the process from start to finish. Setup of the testing units was quick, and you keep them for 48 hours as you go about your regular routine. When Jim came back, he was able to download the results immediately and send them to us via email. I’m so glad we decided to have our home tested, because we had elevated levels of radon in our home which Jim explained was equivalent to smoking a pack of cigarettes per day. I was mind blown, and we will now be looking to remediate. Jim gave us recommendations on local remediation contractors and explained in depth what we should ask them, and what specifically to look for in a remediation company. Can’t thank Jim enough and would highly recommend Reliable Radon to anyone needing affordable radon testing completed. Thank you, Jim!
We used Reliable Radon for our after installation and 2 year check inspections. Jim was great to work with and very informative throughout the testing process.
I work in the medical industry and was the radiation safety officer of my previous company years ago. I consider myself being trained adequately to judge the quality of work of Radon inspection.I am confident to say that you will not go wrong with hiring Jim to do the Radon inspection. He is knowledgeable and understands the regulation thoroughly. He uses the right equipment and tool to do the job.Highly recommended.
I would recommend Reliable Radon to anyone who needs to test their home with or without a mitigation system. We had them come out to do our bi-annual testing. Really great customer service, super friendly, professional, informative and decent fee for retest. We will definitely be using them in future. Thank you again Jim!
Awesome experience with this company. Jim was a pleasure to work with.
Easy to schedule with, timely, knowledgeable and professional. A great experience.
Radon, it’s a thing. During inspection, Radon came out much higher than 4.0 PCI/L reading somewhere in the 16 range, after getting it mitigated, Reliable Radon Inspections, Inc. Did a fast and reliable job retesting. They even saw there was a hidden crawl space that we had not noticed and placed a second monitor to double check for accuracy. Jim, the Radon Technician was professional, friendly and trustworthy. He took the time to talk to me about my own at home sensor and how to keep an eye out for fluctuations and recommended testing timelines. Their results were instant and their report easy to read.…highly recommend.Thank you Jim!
The staff are friendly, knowledgeable and quick to respond to any questions. I would recommend.
Outstanding service and experience from start to finish! Look no further for a reliable friendly company who will take care of your testing needs!
Excellent service. Jim was very professional and explained everything in details about testing and the results.
I never thought about radon until I wanted to sell my home. Jim came in and fully explained what it is, it's effects and the process to remove it. I would definitely call Reliable Radon to check for radon in my new home.
Jim East of Reliable Radon Inspections, Inc. is extremely knowledgeable and is very thorough. He spent time talking about his system and gave us various tips on what to do if we had any type of problems.We highly recommend him!Keith OlsonBolingbrook, IL

I highly recommend Reliable Radon!Jim arrived on schedule, he took his shoes off at the front door without being asked. Thank you for that respectful gesture! He gave me the test results before he left. He was very informative and was a pleasure to deal with.

Great Customer Service
Response from the owner: We wish we could find out how we fell short of a 5-star review. If there is something we could have improved please let us know. This is our first review we have ever received that was not 5 stars... - Jim
Best radon testing company ever!
Loved my experience with them. Super fast to schedule, punctual, competitive prices and very profesional. They are the company who go above and beyond.Jim was super profesional, explaining me the process and procedures, they setup their equipment per my specific house and came back a few days later and gave me a detail report to me and my wife detailing our action steps. I am sure going to use them again.
