Company History
Founded in 1970, the company began as a small mechanical contractor serving municipal and institutional clients. Over decades it grew into a multi-state operation focused on reliable service for larger buildings and industrial sites. Expansion brought specialty departments for boiler work, controls, and preventive maintenance.
The Rapid City location reflects that history: a local office with access to a regional inventory and the technical resources of a larger firm. The company maintains a practical approach to projects shaped by long winters and heavy snow loads common to the Black Hills area.
Leadership
Leadership combines trade experience with regional management. Senior staff have decades of hands-on work in plumbing and HVAC, and managers work with local building officials and trade groups. The team participates in area workforce development and supports training for apprentices in the trades.
