  • "We had a very good experience from the start with J.D. Duke. They came quickly when contacted for a quote to replace a septic tank. The next day Jeff followed up with a detailed quote with the scope of work and price. They were professional and showed up exactly when they said they were going to. The work and inspection went without a hitch. I would definitely recommend them."

  • "We hired J .D. Duke Construction to install a new Eco Flo shell after ours cracked. We are so pleased to have gone with Jeff! Jeff is an upstanding man, an incredibly hard worker, and a true professional. From the moment he arrived until the job was finished, he was knowledgeable, honest, courteous, and took the time to explain everything. We can't say enough good things about him. It's rare to come across someone so dedicated to doing the job right. Thank you, Jeff, for the outstanding service—we truly appreciate everything you did!"

  • "We were under a compliance order to replace our septic system. Jeff came, and did an estimate for us. He was quite busy this year, but still got to our system within a month. He worked with Rideau Valley Conservation on our behalf as well, and was extremely professional. He estimated 5-7 days for the work, and was done on the 5th day, even though he had a dump truck break down while doing our job. We could not be happier with his work, and would recommend them for any job you need doing. The entire backyard has been transformed, and they even seeded grass for us. Our grand children are going to love playing in the yard again."
