Express Central was originally known as Wadena Builders Supply. Wadena Builders Supply started as a wholesaler of plywood and building material for lumber yards in the early 1960's. In 2002 the name Wadena Builders Supply was dropped as we changed our focus strictly to the plumbing and heating trade. Currently Express Central Wholesale Plumbing and heating serves over 500 plumbing and heating contractors in central and northern Minnesota. Express Central will be the best plumbing and heating wholesaler by focusing on exceptional service, quality products, and price-for-value. We will build and grow our company through trust, integrity, state of the art technology along with long term relationships with our customers who we know by name not just a number.
