Every Cleary building is engineered at our corporate office to specifically suit the building site and your requirements. With the assistance of our computerized design system, we can affordably design and build a structure to your precise needs. Our manufacturing plants produce each building to exact specifications, making installation fast and efficient.


We carry an enormous supply of lumber, steel and hardware. With volume buying we are able to hold costs down and have ready access to the material needed to manufacture your building. We use un-spliced Laminated Columns that are superior to the outdated 6′ X 6′ posts and are remarkably stronger. Only “Fabral”,  the highest quality panel in the Post-Frame industry, is used on the roof and walls.


Our specialized equipment allows us to build Cleary buildings year-round. Auger trucks, tractors, cranes and crew vehicles arrive at each building site in harmony with our flat bed semi containing your building. With hundreds of pieces of rolling stock, we have the equipment necessary to back-up our promises.
