    Highly satisfied with the work of G.M.D. Construction Inc (Radon Mitigation Services, Inc) .  This family business (the Deitzs')  were prompt and professional.  They explained the methodology to rectify the problem and were very careful and courteous in their work in our house.  We would highly recommend them.
