JLN Construction Services, LLC (JLN) was established in January of 1997. The company's head office is located in the Hub-Zone of Baltimore, Maryland with another office location in Laurel, Maryland. JLN has grown in value and size through detail orientation, planning and execution of projects.

With over a decade of experience, JLN Construction Services, LLC (JLN) stands out as an exceptional and extensive service provider. Our dynamic approach to our work guarantees that, no matter the challenge, JLN will meet and exceed project delivery expectations.

JLN provides the full suite of construction services to manage, construct, and deliver projects on time. With us, the key concept throughout the construction phase is control—control of schedule, cost, safety, security, quality, and close-out.
JLN uses a method of project delivery in which one entity,our design-build team, works under a single contract with the project owner to provide design and construction services. JLN executes the design flow of work from initial concept through completion. We delivers both horizontal and vertical construction projects with superior results – no matter what the project type. We hire experienced architects and engineers with whom we have relationships, resulting in a highly coordinated effort with exceptional schedule, cost, and risk control.
JLN provides superior excavation, concrete foundation, and concrete flatwork services.
We offer a wide range of services to meet all our customers’ heating and cooling needs. With experienced and trained technicians, we can offer diagnostic, repair and installation services on all makes and models of HVAC appliances and systems.
