"Chris was a clear, effective communicator, very professional, clear and transparent in his billing, and did a clean and effective job. Chris showed up on time, got the job done in the time he said, and made us comfortable and confident in his work. We had a really messed up (and ugly) radon system in our home; what we have now is aesthetically a huge improvement and mitigates radon significantly better. Highly recommended."
