"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."

"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."
