MEP and sheet metal contractor across the Midwest with service and maintenance focus
Waldinger is a 1,001–5,000-person MEP and sheet metal contractor operating across the Midwest since 1906. The tech stack reveals a dual operational reality: legacy building automation (Tridium Niagara, BACnet, Modbus, LonWorks) for mechanical system control paired with modern office tools (Snowflake, Prophix, Bluebeam, Revit) for estimation and project management. Active hiring in construction and engineering, combined with projects around predictive maintenance and commissioning, signals a shift toward service-led growth and equipment reliability.
