John Davis did an outstanding job of correcting a previously installed Radon system in my house. The old system had reduced levels to 3.6 but he was able to reduce the level to 1.6 and I plan to continue to work with him to attempt to reduce the level more.

John did an excellent job for a good price. The radon was brought down to essentially zero and the installation was handled in a way that minimize aesthetic impact on the house. I would, and have, recommended John to others.

John really pulled through for my company in a clutch situation. I asked him to do the impossible, and he did it. It was great to work with him and I have already referred him to many of my colleagues. I had never needed this type of service before, but now I know where to turn should I ever need it again.
