"We were selling our parents home in Illinois and a radon test came back super high 50.8. we were referred to Shawn Santos to solve the issue. From the first conversation to the excellent follow up, Shawn has done a marvelous job of staying in touch and fixing our problem to where it was a reading of 0.8 at the retest!! Far exceeded my expectations on the retest result and the workmanship of putting in the system was very good as FAST! From start to finish the process, took less than 6 days. He answered all my questions As the process went through - He was very thorough and even changed the drawing that wasn’t a big deal, but because I mentioned it to him, he made the corrections on the report for our buyers. I highly recommend Summit - Shawn And his team. Thank you guys for a job well done and the great service that you provided us. Sincerely The Brown family"
