AW Kuettel & Sons B&W old shop with men working

Built on 100 Years of Dedication

Ever since A.W. Kuettel opened his modest small sheet metal and roofing business in Duluth, Minnesota in 1924, Kuettel & Sons has been driven by his philosophy to enrich our surrounding professional communities through structural needs and shelter, no matter how big or small the ask. It’s why this fourth-generation, family-owned business continues to serve the needs of our neighboring industries, with fair and competitive pricing, nearly a century later.

A.W. Kuettel & Sons is one of the Upper Midwest’s most respected and enduring contractors for those seeking services in HVAC, roofing, plumbing, and metal fabrication for commercial settings. We’ve made our professional footprint across a variety of sectors, from mining to grain handling, and forest products to manufacturing and power generation.
