Superb. My agent recommended Benner Geotech. Mike was professional and able to help when I needed him most. His service was much appreciated.

A friend from church referred us to Benner Geotech to take care of a slightly elevated radon level in our new house. Mike was great. He gave us an easy to understand explanation, told us exactly what he would do, and did the job quickly, correctly, and cleanly. He even ended up running a little caulk around the edge of the basement as an extra precaution even though that wasn't on the original quote. I would highly recommend him.
