We had been warned about the high radon levels in our home. After a recommendation from our relatives who live up the road from us, I called.Jay, the owner, was quick to respond, gave us a quote right away, and a week later, we are good! The installation of the fan was very quick, and six hours later, we are already noticing our radon levels going down. Hopefully a full 24 hours later, our levels will be at a normal level! Needless to say, I was so impressed that they got the job done very quickly (about an hour and a half to two hours). They were on time, too!
