Testimonials from Previous Customers

The project went very smoothly. We changed the design of the existing deck. Justin was very thorough and laid out the plan with written instructions and drawings. The office support personnel, Kristen and Brooke were very helpful and responsive. The main members of the crew were Lowell and Joe, who were very professional and accommodating. They also leveled the porch on one side and replaced footings, because it had sagged over time. The finished deck easily passed inspection and looks great. I am very pleased with the result. – Audrey Lawrence; Minnetonka, MN

We couldn’t be happier with how our raised deck turned out. Dupont Construction was very easy to work with. They answered all our questions before, during and after the construction. Wonderful attention to detail. AZEK decks are expensive. We got several bids and Dupont was the least expensive, even before the Angie’s List discount. If you are going to spend money on a deck, make sure it is done right and hire Dupont. –Ann St. Louis Park, MN

I am writing this review to give a strong recommendation for anyone looking to add the features of a deck to your house, to consider using Dupont Construction. From the moment I contacted them to inquire about deck options and pricing, to the first time I could sit out on it and have dinner with my family, they were as thorough, professional, timely, friendly and responsive as I could have hoped for. This was the first time I had been through a process like this. Their patience and expertise in helping me through the entire process allowed me to end up with the deck of my dreams. The gentlemen that built the deck were awesome. If you’re looking for a smooth process from a family orientated company, give Dupont Construction a call. – Molly, Lakeville, MN

Dupont did an excellent job with our new Azek deck. After receiving several bids, Dupont’s price was most competitive and we are very glad we went with them. Office staff was extremely responsive and kept us updated from start to finish. – Emily Woodbury, MN

It couldn’t have gone better! Justin Dupont came to my home to assess the project and give me a bid. I interviewed 3 deck companies for this project and the price of his bid was in the middle. He introduced me to the Azek line of composite material for deck construction, brought many many sample of colors and lots of photos of completed projects. Scheduling was mainly through email with his wife Brooke, who could not have been more responsive. This is the kind of communication you dream of with independent construction people but so rarely find. My emails were always answered promptly, and I will say that we had quite a lot of scheduling to do with the unexpected 19″ of snow in April! Nevertheless, their 2-man construction team was prompt, efficient and hard working–even in the 20 degree weather. In addition–they were neat and tidy, going so far as to clean debris from the dumpster out of my driveway so the snow plows could do their job. An all around excellent experience.– Chris, Edina, MN

Perfectly! They actually came out earlier than planned to build the deck (a huge plus!) and did an excellent job completing the project within the scheduled time. The work was clean, the area cleaned up afterwards, and they treated the house well. No issues with this project and I would absolutely hire them again! – Ed Blaine, MN

Should I build a new deck or remodel/facelift my old one?
