About Our Upper Marlboro Services
Your Trusted Upper Marlboro Electrical Contractor
Upper Marlboro is the county seat of Prince George's County, with a tiny incorporated town (population about 700) at its center and a much larger surrounding area of unincorporated communities (Brandywine, Croom, Aquasco, Marlton) that collectively make up nearly 70,000 residents in the postal zone. Originally settled in the 17th century and named after John Churchill, the 1st Duke of Marlborough, Upper Marlboro is one of the oldest continuously-inhabited communities in the DMV — and its housing reflects that long history.
The historic Upper Marlboro town center contains 18th- and 19th-century houses, the historic Prince George's County Courthouse complex, and a small mix of mid-19th-century homes. Electrical work in the historic district requires the same care as any centuries-old housing: many homes have been through multiple electrical updates over the decades, leaving a layered mix of original knob-and-tube, mid-20th-century rewires, and late-20th-century additions. Tracing existing circuits, planning whole-house rewires, and coordinating with PG County historic preservation review are routine for us in this area.
Beyond the historic town, the surrounding Upper Marlboro area is in active transition from rural-agricultural to suburban-residential. New single-family developments in Brandywine, Marlton, and along the MD-301 corridor sit alongside older farmhouses, ranch homes from the 1970s-90s, and rural properties with overhead services running across large lots. Different housing types need different work: panel upgrades in 1970s-90s suburban homes, service-entrance rebuilds on rural overhead services, generator installations (essential for rural properties with longer power-outage exposure), and EV charger installs in newer subdivisions.
The county-seat status brings government-facility work to the area as well: courthouse-adjacent commercial properties, county-employee residential homes, and tenant electrical for the small commercial corridor around the courthouse complex. We handle both the residential and the small-commercial work with the same crews and standards.
Upper Marlboro residents choose AJ Long Electric for the same reasons our customers across the DMV do: transparent pricing, code-compliant work, careful attention to historic-property preservation when relevant, and a workmanship warranty backing every job.
