Tracing its roots to 1972, the company began as Greenville Builders Supply, founded by ten homebuilders including R. Buford Landers, M. Graham Proffitt III, John C. Cothran, Ellis Darby, David Balentine, Edward H. Hembree, W.N. Leslie, Alvin Trammell, Chester A. Reece, and W.C. Balentine. Construction began in June 1972, and the original Mauldin location opened in October of that year. The company expanded to Anderson within five years, becoming GBS Lumber in September 1979. Subsequent locations opened in Hendersonville, NC, in 1981 and Six Mile in 2005. Growing from ten workers to an employee-owned company with over 100 staff, the firm rebranded as GBS Building Supply in mid-2011 to emphasize expertise in installed sales, green products, remodeling design, and commercial applications. In 2015, GBS joined US LBM, a leading national distributor of specialty building materials.
