"Tim did a great job. He came out and assessed the job. This was a real estate transaction, so he made the timeline work for us. He even completed a few of the other items on our punch list. We got the reduced reading as we needed. Tim is willing to support the new owners questions as well. Great job Tim."

"Had them come out to install a Radon Mitigation Fan. Service was fast and the installer was extremely knowledgable. He was in an out within an hour and the radon dropped from a 4 to a 0.59! Extremely happy with the result. Price wasn't cheap by any means but definitely fixed our problem."
