"Highly recommend. Elijah M was very professional, thorough in his explanations, and always on time. He installed a radon reduction system in our home and walked us through the entire process. We knew everything that was happening and how everything would work before he left. He also tested the system and explained how the test worked when he came back to check the radon levels. We are very happy with the service provided and will recommend Ohio Radon Services to anyone."

"Eric was great! Very thorough on his inspection, and even gave advice on things we didn't even think to ask about. He advised of the things that had the highest safety risk, right down to the small maintenance items like tightening screws. He recommended when to replace air filters, clean the fireplace and some optional things that could help us save money in the future. And the service didn't stop after the inspection, he continued follow-up about the radon testing, and the how to address the safety issues that needed to be fixed. He was very professional and friendly. I would definitely recommend him to friends and family."

"Beatty home inspections was awesome to work with! Being a first time home buyer, we really didn?t know much about the process or what to expect. Chris?s expertise not only made us more knowledgeable about it ourselves, but put our mind at ease that the issue would be fixed. The issue was in fact, fixed. I would recommend him tenfold to anyone looking to get a radon mitigation system put in."
