Commercial Plumbing
in Duluth, MN

Commercial plumbing systems are more complex, more heavily used, and more regulated than residential systems. Northern Sun Plumbing & Heating provides full-service commercial plumbing to businesses throughout the Duluth, MN area, from small retail shops to large commercial facilities. We understand that plumbing problems in a commercial setting mean lost revenue, unhappy customers, and potential code violations, which is why we prioritize fast response times and first-visit resolution for our commercial clients. Our commercial plumbing team handles everything from routine maintenance and fixture replacement to grease interceptor service, backflow prevention device testing, and complete plumbing system installations for new commercial spaces. We are familiar with the specific plumbing codes and inspection requirements that apply to commercial properties in Minnesota, and we coordinate directly with inspectors to keep your business compliant. Whether you manage a restaurant on Superior Street, an office building in the Central Hillside, or a warehouse facility in the industrial district, Northern Sun has the capacity, equipment, and expertise to keep your plumbing running without interruption.
