Dover Septic Tank Cleaning does a fantastic job. They had to come out to our home on a Saturday and arrived 3 hours sooner than expected. Our septic required draining as we had just bought our home and the previous owners never had the septic tank drained. The two men who came out to the house were professional and answered all of our questions about how to care for the tank. I would HIGHLY recommend this company. Everything was cleaned up before they left and we have not had any problems. Thanks, Dover Septic!
