Harbor Contracting

What Harbor Contracting does

Harbor Contracting is a privately held commercial general contractor headquartered in Mount Pleasant, South Carolina, founded in 1985 by David Matthews and currently under the ownership of Pete McKellar. The company provides project-based construction services across eight verticals: office, retail, dental, medical, veterinary, industrial/warehouse, churches and non-profits, and interior buildouts. Its most mature vertical is dental practice construction, with more than 200 dental projects completed across the Lowcountry region. The firm serves predominantly SMB clients including dentists, physicians, veterinarians, small business owners, churches, and non-profits, with occasional enterprise-adjacent clients such as ServisFirst Bank and Carolina Park Development.

The business operates on a quote-based, project-specific pricing model with revenue generated through one-time project fees. No software platform or proprietary technology underpins the service; the core capability is construction project management, subcontractor coordination, and pre-construction planning. The company is relationship-driven, sourcing projects through referrals, repeat clients, and direct outreach via phone, website forms, and in-person meetings. The McKellar family is actively involved in operations, with family members holding client-facing and project management roles.

The company's market is geographically concentrated in the Lowcountry region of South Carolina, including Charleston, Mount Pleasant, James Island, and Johns Island. There is no evidence of external institutional investment, public listing, M&A activity, or geographic expansion beyond this regional footprint. Harbor Contracting celebrated its 40th anniversary in July 2025, signaling continued operational continuity rather than a growth inflection. The company employs 11-50 people and does not publicly disclose revenue figures.
