Our Story

Complete Building Services (CBS) was established in 1963 in response to a growing need for building engineers and maintenance professionals in Washington, DC—and has since turned into one of the most reputable facilities management, operations and maintenance companies in the Mid-Atlantic Region.

Following the energy crisis in the 1970s, CBS created the Energy Management Division to offer customers computerized management of their buildings’ mechanical and lighting systems. After a half-century of success, CBS further expanded to include complete facilities management services, and now maintains major facilities for private and government clients throughout the Washington Metropolitan region. Since our inception, our goal has been to provide technical expertise and cost-effective services to our clients.

Our parent organization, The Donohoe Companies, Inc., was established in 1884. Donohoe and its Construction, Real Estate, Hospitality, Development and Facilities Management divisions are the oldest and one of the largest full-service real estate companies in the greater Washington DC area. CBS is proud to be a part of a team with more than 130 years of tradition and experience serving property owners and operators.
