Gerretsen Building Supply has been proud to serve Douglas County since 1923.

In addition to doors, windows, lumber and building materials, and millwork, our recently remodeled hardware store includes a paint center with state-of-the-art paint matching equipment, plumbing, electrical, hardware, lawn and garden, power tools and more. Whether you’re a homeowner, DIYer, or contractor, we’ve got what you need for your next project.

With the largest inventory of lumber products in southern Oregon, the professional contractor can find competitive pricing, selection, estimating services, jobsite delivery, jobsite measurements for millwork needs and a contractor sales team with years of expertise. Our goal is to ensure that you get the right products to your job on the first delivery and our team is devoted to servicing your project regardless of scale or scope.
If we don’t carry it in stock, we can special order the item.
