WEIDNER PLUMBING & HEATING CO

WEIDNER PLUMBING & HEATING CO specializes in commercial and institutional plumbing, heating, ventilation, and hydronic system installation and maintenance. Their core capabilities include the design, fabrication, and commissioning of complex piping networks, boiler systems, domestic hot water distribution, and radiant heating solutions, primarily serving government-owned facilities. The company demonstrates technical proficiency in ASME B31.1 and B31.9 code compliance, pressure testing protocols, and mechanical system integration within new construction and renovation projects. Their work emphasizes durability, code adherence, and minimal operational disruption—key differentiators in mission-critical environments where system reliability is non-negotiable. Award history does not provide sufficient detail to identify specific federal agencies or recurring client relationships. Consequently, no definitive patterns of agency engagement can be inferred from available data. The contractor’s primary NAICS code, 238220, reflects specialization in plumbing, heating, and air-conditioning contracting—indicating a market focus on mechanical systems integration within public infrastructure projects. This includes institutional buildings such as schools, courthouses, and military installations, where precision in mechanical system installation and long-term serviceability are paramount. The firm positions itself as a trade contractor serving the broader federal construction ecosystem, delivering turnkey mechanical services under prime contractor oversight. WEIDNER PLUMBING & HEATING CO operates as a small, locally based business structured as a 2L entity, with its primary operations centered in Saint Cloud, Minnesota. The company holds no formal government certifications, and its market presence is regional, serving projects primarily within the Upper Midwest. Its business profile reflects a traditional trade contractor model focused on hands-on execution, skilled labor deployment, and field-based project management rather than broad-scale federal contracting or systems integration services.
