After testing for Radon and doing the research to decide that we wanted to mitigate, I started contacting Radon mitigation companies to come and give me a bid. I was a little worried about the installation options since we had a finished basement. I had several of the main Radon installation companies come out to bid and give ideas on how to route the system. I was most impressed with ARS and their design creativity in coming up with a way to install the system with no impact to the finished basement. They came and installed the system on schedule and did a very nice job of cleaning up after themselves. They took the time to thoroughly explain how the system works. Over all we are very happy with how the installation went. I would recommend ARS for a Radon Mitigation system installation.
