"These guys are FANTASTIC! Extremely knowledgeable and taught us so much about the dangers of high radon levels in your home... I'm so glad we had them test for it - our levels were dangerously high and we had no idea! Very professional, informative, and always on time. And they were able to accommodate my crazy schedule! I'd highly recommend the Ohio Radon and Mitigation Company to anyone for peace of mind knowing that your family is safe from this silent danger. Thanks guys!"

"Bill was wonderful and has our highest recommendations. He answered every call and replied to every message promptly, with knowledgeable responses. He was early to the inspection, took the time not only to inspect our new house thoroughly (no rushed feel), but also answered all of our questions as first-time home buyers in a very personable manner. He even inspected the roof despite the rain! Pricing was very reasonable and included all of the work we needed (added radon and pest). His thorough report came as promised later that day, and he answered follow-up questions we had afterward. We felt confident in our decision to move forward with our home purchase because of Bill's outstanding work. It shows that Bill really cares about his work and enjoys what he does. Excellent service, thank you!"
