Our History

Riggs Distler is proud to have more than 113 years in business with an unparalleled commitment to excellence in everything we do.

Over a Century of Service

Founded in 1909, Riggs Distler was originally designed to assist manufacturers in the sale of building and railroad materials. Through the next 20 years, the company’s portfolio would extend into electrical, mechanical, and HVAC, garnering high-profile projects. This would set Riggs Distler on a path toward decades of growth and success, creating a name synonmous with excellence in craftsmanship and business.
