    The whole process couldn't have been smoother. Every person we worked with was professional, experienced, and responsible. They found the most effective solution for our home at a very fair price. Our radon level dropped from 14 pCi/L to 0.5 pCi/L. Thank you so much!

    Excellent experience with Lance Dorfi Radon Mitigation! The whole process was seamless. They arrived in the morning and were finished before noon. Lance was great with communication and patiently answered all of my many questions. The team was also very careful to cover and protect my floors and left everything clean. Best of all, our radon levels went from 3.6 to 0.6! Couldn’t have asked for a better team. Highly recommend!

    I am a Thoracic Surgeon specializing in Lung Cancer. Radon is the second most common environmental cause of lung cancer after smoking, and it is my responsibility to treat those patients. I knew very little about the effectiveness of mitigation technology, or how to reliably monitor safety over time. Lance Dorfi and every single member of his teams were nothing short of brilliant. They were professional, knowledgable, and highly effective. Installation was fast, clean, and high quality without disrupting my home. Were it not for Lance, his explanations of radon mitigation technologies, and the multiple layers of data-directed contingency plans for possible outcomes, I would have backed out of my home purchase. My family and I cannot thank you enough.
