FAMILY BUSINESS, NATIONAL FOOTPRINT

For decades, Wiegmann Associates has helped owners and general contractors solve complex mechanical challenges by getting involved early in the design and planning process. Based in St. Louis, Missouri, Wiegmann Associates is a mechanical contractor focused primarily on HVAC design-build work for commercial, industrial, institutional and specialist facilities across the US. Over the decades, the company has grown steadily by building strong client relationships and delivering consistently, evolving from a regional contractor into a national business with completed projects across 43 states.“ Even with that growth, we still operate very much like a family business. We try to stay hands-on, responsive and practical in the way we approach projects and relationships,” begins Grant Wiegmann, Vice President of Business Development.
