Used construction supplies available for purchase include appliances, cabinets, doors and flooring materials. Additional used construction supplies include lighting, cut lumber, plumbing and roofing materials.
Construction contractors retain certain materials from homes and buildings they are renovating if the materials are in good working condition and under five years old. They also salvage rare wooden materials, antique appliances and vintage cabinetry for collectors and custom builders.
Contractors either sell the used supplies to supply stores and auction houses, or they donate them to non-profit organizations that sell discounted building materials. Sources for used construction supplies include Habitat for Humanity, Skagit Building Salvage, PlanetReuse.com and Build.Recycle.net.
