National Building Supply’s focus and commitment to customer service has fueled our growth over the years as we expanded to three locations in Central and Northern New Jersey. In business since 1962, we sell the finest products and materials available to contractors and homeowners. We offer full product lines ranging from siding, roofing materials, windows, doors, decking and fencing materials, tools, and equipment. This location was formally Myles F.
