"Corey is great to work with. He gave an accurate estimate, was quick to respond to our messages, and did a good job installing the radon mitigation system. Within 24 hours, our radon levels dropped from 15+ pCi/L to less than .5 pCi/L (and still dropping). Corey also ensures his work up to a year after install for free, which gives even greater peace of mind and value for our purchase."
