Serving Colorado since 1979

Duro Electric Company began operations in 1979 with a handful of employees and a few service trucks. Since that time, we’ve grown to be one of the top electrical contractors in Colorado. Our proficiency in competitive bidding, attention to detail and emphasis on integrity and customer service has made our growth and success possible.

Our parent company

Duro Electric is part of MDU Resources Group, which provides essential products and services through two lines of business: regulated energy delivery and construction materials and services. MDU Resources Group has $8.9 billion in assets and $5.7 billion in annual revenues (as of Dec. 31, 2021). The company has been traded on the New York Stock Exchange since 1948 (NYSE: MDU).


Many of our employees have been with us for decades, several since the start of their careers. Longevity feeds a culture of community at Duro Electric, and we extend that sense of community by supporting charitable organizations throughout Englewood and the Denver area.


Much of our work includes smart and sustainable construction practices, whether it’s a LEED certified project or our experienced team making recommendations on value-engineering, procurement and constructability.

Our team includes many LEED Accredited Professionals; additionally, we continually train all our employees on green code and energy requirements, including IECC 2015 standards, to help our customers achieve their sustainability goals.
