Interior Buildouts

From Shells to Spaces.
Built for Business.

Not every project starts with bare ground. Sometimes the challenge is taking an empty shell and turning it into a place where business can thrive. Other times, it is reworking your existing space so it better serves your team and your clients today.
At Harbor, we handle both. From professional suites and retail build-outs to full-scale renovations, we bring the same level of planning, coordination, and craftsmanship to every project, no matter the size. Because for your business, every square foot is an investment in growth.
You focus on running your business. We will handle the construction.

Suite build-outs that set you up for success.

Whether you are opening a new office, retail store, or professional practice, we turn empty shells into efficient, inviting spaces that reflect your vision and help you open your doors faster.

      My husband and I used Harbor Contracting for the build-out of our second business location. We truly cannot say enough positive things about Pete (owner), Harbor, and the team in general.

      Darlene was our project manager and she was always very communicative, responsive, and efficient. It was also nice to hear from Pete on occasion - it's often hard for a business owner to know each of their clients/projects, but he somehow manages to do this very well - it certainly adds a personal touch.

      Our space went perfectly as planned. We would without a doubt choose Harbor for any future projects we have. Thanks Darlene, Pete, and team!

        Charleston Dental Studio

        Working with Harbor Contracting, Preston, Dave, and their entire crew, was one of the best decisions I made during the process of opening my dental practice, Charleston Dental Studio. This was my first dental office buildout, and I went into the project with a clear vision but very little technical experience. From our first meeting to the final walkthrough, the Harbor team delivered a level of service, communication, and professionalism that exceeded every expectation.

        Preston and Dave were professional to the highest degree, consistently available, oftentimes outside of normal hours, to answer questions, talk through decisions, or walk me through next steps. They treated the project like it was their own and truly became trusted partners in the process. I never once felt like I was “just another client” or that my concerns were brushed aside. They were patient, responsive, and incredibly generous with their time and knowledge.

        They took a thoughtful, educational approach helping me understand construction timelines, materials, permits, cost-saving options, and design decisions without ever pressuring me. Every suggestion they made came with a clear explanation and genuine respect for my vision and goals. As a healthcare provider, that transparency and trust meant everything.

        Harbor Contracting worked seamlessly with my other vendors, coordinated inspections, and handled unexpected curveballs with ease. Their craftsmanship is excellent, their timelines were realistic and well-communicated, and their commitment to quality showed in every detail of the finished space.

        If you’re a dentist, medical professional, or small business owner looking for a top-tier dental office contractor in Charleston, I wholeheartedly recommend Harbor Contracting. They understand what it takes to bring a healthcare space to life not just structurally, but also in terms of workflow, aesthetics, compliance, and patient experience.

        Because of them, I now have a space that not only looks beautiful but also functions beautifully for both our team and patients. I’m deeply grateful for everything they did to bring Charleston Dental Studio to life.

            Andrew McKellar and Paul Rice have been outstanding to work with.
