Full service contracting firm with a proven track record.

"As a start-up who was quickly growing out of our space, we were looking for tight timelines and tight budgets as we built out our new space on Atlantic Ave. We also needed a contractor who was able to assist and support our small internal decision-makers. KDJ was able to step in and complete our office build out in just a month's time, coordinating with vendors to take the pain out of managing subcontractors, and turned our sad, outdated, top-floor office into a fresh, functional, and beautiful office that our team is excited to come to every day.""

"We have been absolutely thrilled to find KDJ Contracting, LLC. Derek and his team are incredibly responsive, thoughtful and professional, and the quality of work is beyond our expectations. Our real estate portfolio includes structures that are over 150 years old and bring with them a series of challenges that an ordinary contractor might overlook. Derek’s ability to listen to client needs, assist in project planning, and consider practical implications in advance of construction is highly unusual in general contracting and leads to a superior result – and perhaps just as important, provides the owner/manager with peace of mind. Derek and his team make your problems his problems, and ultimately your successes. We can’t be more happy with this relationship and we are thrilled to have found KDJ Contracting." Ken Itrato, Esq.

“I have worked with Derek on both residential and commercial projects over the past several years. He is a problem solver and gets things done without hassle and isn’t afraid to get his hands dirty. Derek is a great pleasure to work with too which goes a long way towards successfully completing a project on time and on budget.” Matt Kane

"Working with Derek Lively and KDJ construction was a pleasure from start to finish!
We closed on our home on October 11th and needed to move in on the 18th. Due to the fact that we bought an antique, there was a laundry list of things that needed to be done to the house and completed in a very short time period. Derek never batted an eyelash at any request and worked tirelessly to get the job done. For example; there was a moment where the tile we had ordered for the new master bathroom shower was supposed to be delivered and ended up not being loaded on a delivery truck. This would have delayed the whole project and we would have had to find another place to shower for a solid week. I called Derek to inform him of the situation and before I knew it, he was texting me pictures of the loading dock where our tile was (2 hours away!!), thus allowing the bathroom/shower to be finished on time.
If you are looking for someone to go above and beyond, then KDJ is the perfect fit. Everything we needed done was done professionally and done with taste. Derek Lively and his team, listen to your needs and opinions. They work hard and seamlessly together to get the job done in the quickest time possible and at the best price possible!
A huge THANK YOU to Derek and the rest of KDJ!" Johnny Lonborg
