Our History

Joseph Heffron founded the oldest mechanical contracting firm in Washington, Heffron Company in 1922.

Home from his World War I service as a sergeant, he started the company in the second story loft of the carriage house behind his family’s home at 12th Street and Independence Avenue, S.W. Washington, D.C. He built a strong company in the thriving 1920’s, strong enough to survive the lean years of the Great Depression and World War II. His daughter, Eileen, and her husband, George Dunn Sr., took over the business in 1946, proud to carry on the Heffron tradition of quality and craftsmanship.

Today, after more than 80 years in business, the integrity and dedication that earned Joseph Heffron the respect of architects, engineers, and builders throughout an earlier Washington are still Heffron’s hallmarks. Joseph Heffrons’s grandson, George Dunn Jr., continues to build on a strong family leadership and a highly trained professional staff to strengthen Heffron’s reputation for excellence.

Serving major utilities, general contractors, architects, engineers, property owners, and property managers, Heffron is a company whose respect for tradition and commitment to client service are matched by its strong entrepreneurial drive and its keen grasp of today’s technologies.

Heffron Company’s relationships with its clients are measured in decades. PEPCO has relied on Heffron for more than 65 years, Georgetown University for 70, Safeway for more than 40, the U.S. Chamber of Commerce for 25. Those relationships are built on trust – the only foundation strong enough to support the long-term strategic alliances that have characterized Heffron’s eight decades in the Washington business and construction-industry communities.

Building a successful business history takes more than just technical capability. It takes an honest commitment to partnership-to being a team player, dedicated to the success of the project. Heffron’s extraordinary track record of solid collaboration with construction partners and long-term relationships with clients reflects the company’s fundamental commitment to wording together to resolve problems.

Heffron focuses multidisciplinary expertise on state-of-the-art mechanical systems in ways that reach new heights of energy efficiency and cross the frontiers of creative problem solving. That is one part of innovation. Another is adding unexpected value-value that may spring from Heffron’s entrepreneurial instincts, economic strength, local experience, or longstanding construction-industry alliances.

Heffron Company brings together the technical capabilities; financial resources, managerial strength, and local and regional alliance necessary- especially in today’s competitive marketplace-to bring even the most challenging projects to successful completion. Heffron gets the job done, on time and within budget.
