This Lumber yard is the best in the business. Don't even think for a moment of going to Menards or Home Depot. When it comes to building materials, if Hartje doesn't have it, then it doesn't exist

I've only dealt with these people a handful of times. But every time they were pretty quick to get on their feet and help you and get things ordered or sent out to you that you needed or at least point you in the right direction. When I reroofed my house, they had the materials delivered on site when I asked and we're pretty good about offering any insight if you had questions. Aside from that they have a huge selection of materials for commercial or residential building.
