About Our Greenbelt Services
Your Trusted Greenbelt Electrical Contractor
Greenbelt is one of the most distinctive small cities in the DMV — a federally-planned New Deal "greenbelt town" built in 1937 by FDR's Resettlement Administration as a model of cooperative suburban living. The original "Old Greenbelt" historic district remains remarkably intact, with its Art Moderne row houses, central pedestrian-only commercial square, and the Greenbelt Theatre still operating as a single-screen cinema in its original building.
The Old Greenbelt historic district is the most electrically distinctive housing in Greenbelt and presents unique challenges. The 1937 row houses were built to deliberately modest specifications using federal-government construction standards of the era, with minimal electrical capacity by today's standards. Many original units retain their 1930s service panels (some still with fused service entrances), small-gauge branch wiring, and limited circuit capacity. Modernizing these homes for current electrical loads — central HVAC, modern kitchens, dedicated circuits — requires careful work that respects both the historic preservation overlay maintained by the City of Greenbelt and Greenbelt Homes Inc. (the cooperative housing entity that owns most Old Greenbelt units) and current NEC code requirements.
Beyond Old Greenbelt, the city extends east into newer 1960s-90s single-family and townhouse developments around Greenbelt Park and the Beltway, plus newer multifamily and mixed-use developments around the Greenbelt Metro station and the NASA Goddard Space Flight Center campus. These newer areas present standard suburban electrical work: panel upgrades, EV charger installs, battery backup and generator hookups, and dedicated-circuit additions for home renovations.
NASA Goddard's presence brings a steady stream of federal-employee homeowners who tend to be detail-oriented about home systems — when a Goddard engineer calls us about a panel upgrade or EV install, the conversation often starts with circuit-load calculations. We meet that detail-orientation with detail-oriented work: clear upfront pricing, code-compliant installations, and thorough cleanup.
Greenbelt residents choose AJ Long Electric because we understand both the historic-preservation constraints of Old Greenbelt and the modern-suburban needs of the rest of the city. We pull all permits through City of Greenbelt and Prince George's County, and we stand behind our work with a workmanship warranty.
