Reliable began in 1928 when two ambitious brothers, Frank and Bill Baldwin, came together and bought their first used dump truck to begin hauling for various jobs up and down Route 3 in Gambrills, MD. From there forward, they began bidding on larger county, state & federal contracts winning their first state contract in 1938. 

Unfortunately, World War II sent the brothers back to farming forcing them to park their trucks. It wasn't long, however, before Frank's son, Thomas I. Baldwin, would be following in his father's footsteps after graduating college. Thomas would soon lead Reliable into the land development business. This was just the beginning of the Baldwin family's involvement within the company while there are currently 2nd, 3rd, and 4th generations of the family in active roles today. While Reliable may be viewed as one large family by its very own employees, there are in fact many multi-generational families currently working within the company, from the office to plant management to project oversight. 

Over the years, Reliable has maintained a reputation as a leader in the construction industry. Our clientele includes builders, developers, individuals, and government agencies. With projects ranging in cost from $100,000 to over $25 Million, Reliable can be seen working on Maryland's roads, highways, airports, office parks, shopping and lifestyle centers, hospitals, churches, and residential developments earning our reputation by providing clients with consistent quality and value to their projects.


This reputation led to many valuable and meaningful long-standing partnerships with other industry leaders opening up opportunities to get involved in other avenues within the industry. Thus, to continue providing innovation and commitment in our work and aiming to establish meaningful relationships and provide superior service and solutions to our partners and customers, The Reliable Companies was formed. 

The Reliable Companies is a combined effort of multiple teams providing services in the various areas of joint-venture projects, bringing our customer's and partner's projects from concept to concrete.
