I really didn’t give radon a second thought until I saw a commercial on television explaining how dangerous it was. I decided to do some testing and wow… my level was at a 15… WAY above the safe limit. I contacted RSI and they made the entire process so easy. Chris was on time and professional. I’m kind of a neat freak, and seriously he left no type of mess whatsoever! My radon level has dropped from a 15 to a 2.4! The system itself looks great and obviously does the job. I would recommend Chris at RSI to anyone that has this dangerous gas in their home. Reliable, clean and effective work!
