"I would definitely recommend this company to anyone!!! I hired them and the job was done nicely, Dan O'Brien was the technician who took care of the project and he did an excellent job, he answered all of my questions and explained to me everything related to Radon gas. When he finished setting everything up and the job was completed all the working area looked super clean and the installation looks just like it is part of the house and that has been there forever. This is what I call a Perfect and Complete execution of a Radon gas mitigation project."
