Since 1964, Guaranteed Supply Company has grown to 15 locations. Along the way, we have expanded to feature product lines focused on Concrete Materials, Thermal and Moisture Protection, EIFS/Stucco Products and more. As well as building the largest, independently owned, custom rebar fabrication company in the Carolinas - JMS Rebar. Throughout this journey, Guaranteed Supply Company has kept the same attention to personal care and quality materials that started it all.
