GBS Building Supply

What GBS Building Supply does

GBS Building Supply is a regional specialty distributor of building materials headquartered in Greenville, South Carolina, operating five branch locations across South Carolina and North Carolina and serving customers in the Carolinas and parts of Georgia. Founded in 1972 by ten homebuilders as Greenville Builders Supply, the company was renamed GBS Lumber in 1979 and rebranded again in 2011 as GBS Building Supply to reflect a broader product and service portfolio. Since 2015, GBS has operated as a subsidiary of US LBM, one of the largest specialty building materials distributors in the United States, while maintaining its local builder-focused identity.

The company sells nine core product categories — lumber and building materials, roofing and siding, windows and doors, decking and railing, kitchens/baths and cabinetry, moulding and millwork, columns and trim, insulation, and locks — through a single-source supply model. These products are complemented by professional services including material estimating and take-offs, jobsite delivery via a fleet equipped with all-terrain forklifts, engineered wood floor-system design, and the ADVANTAGE+ business growth program. The GBS Mobile App extends these services digitally with billing access, real-time delivery tracking, and proof-of-delivery documentation. The Elevations by GBS sub-brand operates as a premier cabinetry and design showroom featuring 3D design capabilities.

GBS serves a diversified base of professional builder customers across six segments: residential builders, remodelers, custom builders, commercial and multi-family builders, specialty contractors, and property managers. Revenue is generated primarily through wholesale building materials sales supplemented by professional services revenue. Pricing is quote-based rather than published, reflecting a project-driven sales motion supported by dedicated account representatives, in-person branch sales, and enterprise field sales for commercial accounts. The company operates a sales-led, relationship-driven go-to-market model anchored in physical branches, jobsite delivery, and trade association membership across NAHB, NKBA, and regional homebuilder associations.
