Des Moines-based mechanical, electrical, and sheet metal contractor The Waldinger Corporation has acquired United Mechanical Group, a commercial plumbing, HVAC, and process piping contractor founded in Champaign in 2017. The financial terms of the deal were not disclosed.
The acquisition adds Champaign to Waldinger's Central Illinois footprint, making it its third market along Central Illinois' I-74 corridor after Peoria and Bloomington. This is Waldinger's sixth announced acquisition since January 2025.
Waldinger is a privately held regional contractor that has been acquiring companies for decades. In its recent deals, it has generally kept local brand names and leaders in place. The company publicly states it is looking for MEP construction firms and HVAC, refrigeration, beverage, ice machine, and commercial cooking service companies. Its recent acquisitions indicate a focus on markets where it can add trades next to an existing branch, acquire a local name and client list, and retain leadership.
