SINCE 1953


From our beginnings in 1953 as Allenton Lumber and Fuel with 5 employees, Zuern Building Products, through the dedication of now well over 100 employees, has grown to be one of the largest independent, family-owned and operated lumber and building material suppliers in Wisconsin.

Zuern Building Products supplies a full line of building materials to professional builders, remodelers, and homeowners. We have four expansive lumberyards with complete showrooms in Allenton, Cedarburg, Franklin and Watertown, Wisconsin. Since 1953, we’ve been family-owned and operated. We take pride in our tradition of providing high quality building materials and valuable services to our customers. We are “Building on Service!”

As our retail operations have expanded, we’ve been able to add services to meet the needs of our clients. From traditional lumber, millwork, windows, doors, and cabinet supplies to trendsetting home and kitchen and bath design, our team remains focused on making life easy for our clients. Our design staff can help you design and plan a project, create a products list, and deliver products directly on-site.


The mission of Zuern Building Products is to maintain a dominant market position in the sale of building materials to the professional, through the combined efforts of management and a team of dedicated employees, adhering to a standard of honest and ethical business practices.
