"I couldn't have asked for a better experience. I checked a few Radon companies and Certified Radon was the best. They seemed to be the most knowledgeable, had the best warranty/guarantee, and actually came in cheaper than some of the others. They brought my radon level from a mid-6 to less than 1 on the first test. If you need radon services I would highly recommend."

"I had them come and give me an estimate. Josh was very professional and respectful. He gave me a written estimate right away. I would love to get the work done but cannot at this time because it cost too much and I am on fixed income. They will be the first I will contact should I decide to have the asbestos removed."
