Based in St. Augustine and serving Northeast Florida, JDuff Construction Co. handles tenant build-outs, renovations, and ground-up commercial projects with a hands-on approach and trusted local crews.
JDuff Construction Co. is a locally owned and operated commercial contractor, focused on building strong relationships as much as delivering quality projects. We work closely with businesses on tenant build-outs, renovations, and new construction, taking a hands-on approach supported by trusted local partners we know and rely on. From the first conversation through final completion, we stay involved, communicate clearly, and take real ownership of the work. Every project is guided by care, consistency, and a commitment to doing right by the people and the community we serve.
We handle every phase of your project across Duval County, St. Johns County, and the surrounding Northeast Florida area, from early planning through final walkthrough, so nothing falls through the cracks and you always know where things stand. Our focus is on keeping the process clear, the work accountable, and the people behind it genuinely invested in the outcome.
We take the time to understand what matters to you, then plan and price the job right from the start so there are no surprises down the road.
We stay involved from day one to final walkthrough, keeping things organized, communicating clearly, and making sure the work is done right.
We bring the right people to the table early and work as one team, keeping your project straightforward, efficient, and aligned from start to finish.
We give honest input based on real experience, helping you think through decisions, avoid common pitfalls, and move forward with confidence.
We work with local business owners, property managers, real estate brokers, and tenants throughout Jacksonville and Northeast Florida on everything from renovations and improvements to ground-up new construction. Whatever your sector, we bring the same hands-on approach and accountability to every project.
We’re here to talk, not sell. If you have a project in mind, reach out, and we’ll take the time to understand what you’re trying to accomplish. From there, we’ll walk through it together, answer your questions honestly, and help you figure out the right way forward.
You will be working directly with our owner and team, including the people leading the work in the field. We do not pass clients off to layers of account managers or separate departments. The same people you meet at the start stay involved through completion.
We work with local business owners, small commercial tenants, and property groups like leasing and brokerage firms. Our focus is on clients who value communication, accountability, and a more personal approach to construction.
We are intentionally structured to stay small and involved. That means fewer handoffs, more direct communication, and a team that remains accountable from start to finish.
We stay connected throughout the entire process. You will always know who to talk to and what is happening on your project. We keep communication direct and make sure you are never left guessing where things stand.
Tell us what you’re working on and we’ll walk it through with you, answer your questions honestly, and help you figure out the next right step. Contact our team at JDuff Construction Co. today to get started.
