Advance Building Supplies was built by contractors, for contractors. After decades in the exterior renovation industry, we saw firsthand how hard it was to find reliable equipment, fair pricing, and suppliers who actually understood the job. We focus on practical, proven products like KWM gutter machines, Zip Hinges, and specialty exterior materials that help crews work faster, cleaner, and more profitably. Based in Canada, we work with contractors and retailers across the country, offering honest advice, dependable support, and products we have used use and stand behind ourselves.
