    Mike and his team were incredibly helpful. He took a great deal of time to help us to diagnose the issue, ensuring that we truly needed to have work done. We planned everything out well in advance, communicating regularly along the way. The work he performed for us was top quality, and they treated our house as if it were their own. Our situation was uniquely complex, which he did not charge us very much additional for. I would completely recommend others to work with his team, both on service and on value.

    Mike is thorough, responsive to communications, reliable and left worksite spotless. System install was done efficiently and looks great and runs quietly and most importantly our radon levels have been mitigated to significantly below acceptable levels

    We recently bought a home that needed both radon water mitigation and air mitigation. Luckily we had Mike handling our situation. He was professional from start to finish with educating us on how to properly maintain the equipment and his demeanor was polite and helpful. We are very grateful for his excellence in this field. We highly recommend this company!
