I needed radon mitigation and did my due diligence to find the best company. Ian responded first and beat the 2 other companies in price, scope of service provided, and availability to install. He was on time with the free estimate we scheduled, and subsequent installation. I was so impressed, I have referred Ian to others.

Ian is a pleasure to work with, professional and gregarious. The mitigation he performed is picture-perfect and was installed quickly. The wiring job was particularly careful (not always the case with other contractors...) and everything was properly sealed.
