Recent Review: We were selling our house and the radon test indicated that our radon level was elevated. One of the conditions of selling was radon mitigation. So we requested quotes from a number of companies. One Day Radon was the first to respond. Clif came to our house and explained the process in detail. I found him very personable and knowledgeable. He answered all of my questions and gave me a quote on the spot. As it turned out, he gave me the best price. It was a no-brainer to select his company for the best price, the best quality, and the best service! During final negotiations, the buyer agreed to pay for the radon mitigation so I had to cancel my agreement with Clif.
