Duluth · Twin Ports · The Northland
Building the Northland's most demanding commercial projects.
Since 1924, A.W. Kuettel & Sons has self-performed the trades that make landmark buildings work. We handle plumbing, HVAC, roofing, architectural sheet metal, and custom fabrication, all under one accountable roof.
Commercial Services
Six trades. One accountable partner.
Because we self-perform across disciplines, your schedule, budget, and quality stay in one set of hands, not splintered across a dozen subcontractors.
Plumbing
Our own licensed crews install and service commercial and institutional plumbing systems, from underground rough-in to finished fixtures.
HVAC
Design-build heating, ventilation, and cooling for offices, schools, healthcare, and industrial facilities, engineered for comfort and efficiency.
Roofing
Standing-seam metal, slate, and membrane roof systems built to shed Northland snow and weather for decades, not seasons.
Architectural
Cupolas, steeples, copper details, and custom cladding. It's the architectural sheet-metal work that gives landmark buildings their signature.
Metal Fabrication
Our own fabrication shop produces custom stainless, copper, and steel work, including countertops, hoods, flashing, and one-off assemblies.
Mechanical Engineering
In-house mechanical engineering ties the trades together, with coordinated systems, accurate budgets, and constructible documents from day one.

Why Kuettel
The partner owners and GCs call for the work that can't go wrong.
Single source of accountability
Self-performing six trades means fewer handoffs, tighter coordination, and one number to call when it matters.
A century of reputation
Generations of Northland landmarks carry our work. We protect that name on every project we touch.
Engineering up front
In-house mechanical engineering means realistic budgets and constructible plans before the first crew mobilizes.
Our own fabrication shop
Custom metal is made here, on our terms and our schedule, not bought from a queue across the country.
Built for the Northland
Systems and roofs engineered for real Lake Superior winters, not a generic climate spec.
Safety without compromise
Licensed, bonded, and disciplined crews who finish the job the way we'd want it done on our own building.
About A.W. Kuettel & Sons
A Northland name builders have trusted for generations.
A.W. Kuettel opened a small sheet metal and roofing shop in Duluth in 1924. Four generations later, that family business has grown into a full-service commercial contractor, but the philosophy hasn't changed. We take on the complicated, high-visibility work other contractors hand off, and we do it with our own people.
From hospital mechanical systems to copper steeples on the skyline, we partner with owners, architects, and general contractors who need a single team that can engineer it, fabricate it, and install it right the first time.
