When our Grass Valley home was in the process of being sold, the buyers insisted on a septic certification. We were told that the 52 year old system, which had never given us any problem in 10 years, needed to be replaced because the flow was too slow. Two companies were recommended and we chose J&D Construction, which turned out to be the best thing we could have done. Mr. Hudson not only did the required work, he intervened when the county directed that further unnecessary work be done, and saved us a good deal of trouble and money. It would have been to his benefit to do the extra work, but he is clearly an honest businessman. He was professional, responsive and at all times courteous to both of us, and we would recommend him unequivocally to anyone. Chuck and Linda Eckerman, formerly of Grass Valley, CA
