My neighbor recommended Reliant Radon Solutions. My experience left me feeling impressed and confident. The owner, Terry is very professional and caring. The installer, Joe was prompt, knowledgeable and thorough. He explained everything from start to finish.

I asked Terry to come evaluate the radon system the previous owners had installed as our level was right below 4 when we bought and we wanted to maximize the system. Then we tested again while the house had been closed up for the winter and our level was well over 4!! She immediately flagged inadequ... See More

Terry and her team were amazing. I appreciate Terry walking through the options with me. The team installed on the day scheduled in a timely manner. The few follow-up items were handled quickly. Pricing was competitive to other bids I received.


These people apparently wrote the book on how things should be done. Not only are they courteous and professional, they take their relationships with their clients personally,
going above and beyond what they are
contractually obligated to do to make the total experience as easy and hassle free as... See More


Amazing A+ service. Terri was absolutely amazing in helping my client understand mitigation and the steps needed to remedy. She took personal time on her cell phone to answer questions and make everything happen. Recommend to anyone looking for radon help.


Terry is phenomenal. Extremely knowledgable and took the time to walk me through each phase and what to expect. Very lucky to have partnered with them. Highly recommend!


Very good ,responsive company. From 1st test to installation, Terry and Heidi were always informative and answered the phone and our questions even when out of town! Jay the installer completed the job on a cold day and never stopped till finished! And a well done job it is. Thank You Reliant!

Reliant Radon is fantastic. Absolutely professional and knowledgeable about Radon. Lovely to work with and feel much better after they've put in the system, knowing our Radon mitigation is guaranteed.

In a world of endless choices, I’m glad I went with Reliant Radon Solutions. They got back to me immediately, and I heard from the owner, Terry. I had a quote within a day or two, the price was more than fair, and on installation day, the tech, Jay, was prompt, kind, efficient and did a marvelous ... See More

My installation was the "cleanest" installation of any home repair or installation I have ever had. Joe left no trace or clue that he was ever in my home. The company provided sketches of the installation for HOA approval, and made the whole process very easy. I would recommend Reliant Radon Solutio... See More

My levels went from over 9 pCi/L to 1.1 pCi/L!


Joe was professional and clearly knew what he was doing. Before starting the job, he went over everything with me making sure all my questions were answered. When he was finished he explained clearly all that he did and what I needed to do in order to do my own radon test in 48 hours. I wish all wor... See More


Thank you VERY much Reliant Radon Solutions! We were in a bind to get our radon mitigation system in before we closed on our home. They called us after hours, moved their things around to get us in the schedule and then did a fantastic job! They even painted the pipe on the outside of the house. ... See More

The entire Reliant team has been a pleasure to work with. From the quote process to installation they were on top of their game. Joe, our installer, is a great guy.

Jay did a great job and was very efficient. The only question I have is why the stand pipe doesn't have some kind of cap on it to deter birds and rain from going into the stand pipe. I would really appreciate some kind of a cap on it. Thank you.

I am very happy with the service I received from Reliant Radon Solutions. They were the only radon mitigation company to actually come to my house and prepare a quote for me. The installer was very kind and knowledgeable. When our original plan for mitigation did not work, he quickly gave me opti... See More


Good communication, easy scheduling, competent people. I dropped the ball on them (I forgot about an appointment) and they were able to work around it. Five stars!

Reliant Radon Solutions did a fantastic job installing our radon mitigation system. Our reading has come down from 5.1 to 0.6 pCi/L 4 days after the installation. When I was shopping around for an installer, the owner Terry was the only person who actually came to our house and gave a final quote. S... See More
