Comments: Just a word or two to say many thanks for your good work in the radon mitigation at our home. Prior to any work being done were shocked to see that the average reading was 21.7 pCi/L. We definitely needed some work done! You and your men did a great job! We held our breath to see what the post mitigation test results would be after your work…and breathed a great sigh of relied when it came in at an average of 1.2 pCi/L, Wow! So many thanks for your good work. We very much appreciate it.
