(Nov 2016) I needed a quote for Radon Mitigation, checked HomeAdviso, and found American radon. Bill called me within a half hour, and showed up here within an hour to look over the job and give me an estimate. Within two hours I had an e-mailed estimate. I called him back to do the job, he was here within a couple of days, the work was done very well and there was absolutely no clean up for me. It was all done. I would definitely recommend this company if you're looking to get mitigation done.
