Uptown Family Dental
Working with Harbor Construction was an incredible experience from start to finish. The McKellars and their entire team helped bring the vision for our dental office to life—and the final result truly exceeded our expectations.
Their efficiency, professionalism, and attention to detail were evident in every step of the process. Everything was done on time, done right, and done with care. The quality of their work is top-tier, and it shows in every corner of our space.
We’re beyond thrilled with the outcome and will absolutely be using them again in the future. If you’re in need of a professional, reliable, and efficient contractor, Harbor Construction is the team for you. We can’t recommend them enough!

Exhale Pilates
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.
