Dave and his family did a great job replacing our septic system, which we needed to have installed after purchasing our new home in Hopewell Twp. NJ. The engineering plans were already developed by the previous owner. Being new to the process, Dave took the time to come out one morning and explain the plans to me before we were ready to schedule the work and proceed. His price was competitive and he worked efficiently, keeping me informed along the way. It was really impressive watching all of the work and machinery right in our backyard, snow-covered ground and everything. There was only about

Dave and his team did a great job installing a new septic system, including relocating the drainage field in the back yard with as little disturbance as possible. They answered questions before and during, and also afterwards with some follow ups that I had.

Dave and his team were wonderful to work with. They kept me informed every step of the way with the installation of a replacement septic system. It required going to the back of my property and Dave worked around the weather to take proper care of my landscaping and grounds. Everything passed inspections; in Lawrence Twp. which has a reputation for being difficult. The system change over was seamless. I highly recommend DPD!

David and team replaced a whole septic system for my home. Extremely professional outfit as he was hands on and communicative during the whole process. I specifically like the steal plates used for the trucks for which helped to protect the lawn etc. He goes the extra mile to work with you and addresses any concerns you may have. I felt very secure while the work was being done, as one can imagine your lawn is torn up to have the system installed. I love how he landscaped with new grass seed. My backyard looks beautiful once again. Thanks D.P.D.

Dave and his family were extremely helpful from Day 1. I had to replace my septic system in order to sell my house. Dave came over and explained the process and recommended a great engineer. He stayed in contact through the engineering process and permits to know where to schedule me in. His proposal was very budget friendly and no surprise additional costs even with removing a portion of the fence and moving playground equipment. He and his family work together and are very friendly, professional, and thorough. At the end, Dave and his family cleaned up their equipment, yard, seeded, and placed

Dave and his team are truly professional and courteous. They replaced a failed residential system with observable experience by all the team, and a very high work ethic. Yes, Dave was present every day both working and ensuring that all was done correctly and to every code. Any question that I asked of any one was fully answered or explained with a willingness to help you understand. What Dave said would be done, even from the first consultation, was. I am more than pleased with the work and effort given to my needed project. DPD Contractors merit being contacted. To me, their rating should be
