Complete Guide to Electrical Panel Upgrades in Northern Virginia
Everything Northern Virginia homeowners need to know about electrical panel upgrades, including signs you need one,...

Property-specific electrical panel replacement and service-capacity planning, with load calculations, utility coordination, labeling, and permit-path confirmation. Trusted by homeowners throughout Prince George's County since 1996.
An electrical panel project should start with the condition of the existing equipment and the loads the home needs to support. AJ Long Electric documents the panel, service conductors, grounding and bonding, breaker configuration, available space, and visible signs of heat or damage. A load calculation helps determine whether the project calls for a like-for-like replacement, additional distribution capacity, or a service upgrade. When the scope affects utility-owned equipment, the meter, or service conductors, that coordination is identified before scheduling. The written proposal separates panel work from optional surge protection, branch-circuit corrections, finish work, and other conditions that cannot be confirmed until the system is evaluated. For a Laurel property, the recommendation follows the actual equipment, access, electrical capacity, and project goals documented during the assessment.
Laurel is geographically odd: the city straddles the corner where Prince George's, Anne Arundel, Howard, and Montgomery counties meet, with the bulk of it in PG County. Its housing is just as mixed — 19th-century mill-workers' homes in the Old Town historic district sitting a few minutes from 1990s-2010s townhouse rows — and a panel upgrade in Laurel can mean two completely different jobs depending on which Laurel you're in.
AJ Long Electric defines the panel replacements & upgrades scope for the individual Laurel address. The written proposal identifies known conditions, access assumptions, included electrical work, exclusions, and any coordination that must be confirmed before scheduling. Before work begins, we confirm whether the defined scope requires coordination with the Prince George's County Department of Permitting, Inspections & Enforcement; permit, inspection, and utility responsibilities are stated in the proposal for the address.
The defining panel-upgrade question in Laurel is vintage. In Old Town Laurel — 19th-century mill housing, Queen Anne and Folk Victorian homes — we work around period millwork and plaster while replacing knob-and-tube and 60-amp fuse panels, often coordinating with the City of Laurel's historic-preservation review so the exterior keeps its period appearance. In West Laurel and South Laurel the midcentury ranchers and capes bring a different recurring item: Federal Pacific and Zinsco panels whose breakers have a documented reputation for failing to trip, which we replace outright rather than reuse. Both kinds of upgrade move the home to 200-amp service ($3,500-$7,500). Laurel sits in the Patuxent River storm corridor on the Pepco grid, so panel upgrades here are frequently paired with a transfer-switch or battery-backup hookup for storm reliability. Permitting runs through Prince George's County DPIE, with City of Laurel review added for Old Town addresses, and we coordinate the Pepco meter pull.

For panel replacements & upgrades at this Laurel property, AJ Long Electric begins by reviewing the requested outcome, relevant equipment, safe access, and observed electrical conditions. The written proposal identifies the defined work, sequencing, coordination responsibilities, and exclusions. Authorized work is tested and documented to the completed scope; newly exposed conditions are discussed before the scope changes.

We document the panel, service equipment, loads, grounding, breaker configuration, and visible conditions.
The recommended capacity and equipment follow the existing and planned electrical demand.
The estimate identifies included equipment, corrections, coordination, access, and exclusions.
Permit, inspection, outage, and utility requirements are confirmed for the address.
The approved equipment is installed, terminated, grounded, bonded, and labeled to the defined scope.
Connections and operation are checked, the directory is reviewed, and applicable closeout steps are completed.
The exact scope depends on the existing service and the load calculation. It may include the panel enclosure, breakers, grounding and bonding corrections, service conductors or meter equipment, labeling, utility coordination, and required inspection work.
We use the home's existing and planned loads, equipment ratings, service configuration, and the applicable calculation method. A larger rating is not automatically the correct answer for every property.
Brand and age alone do not describe the complete condition. A licensed electrician should identify the exact equipment and evaluate damage, breaker compatibility, service capacity, grounding, and the homeowner's planned loads before recommending a scope.
That depends on the service configuration and work boundary. When utility disconnect, meter, or service-entrance coordination is needed, it is identified and scheduled as part of the project plan.
Permit and inspection requirements depend on the address and defined scope. AJ Long Electric confirms the authority and coordination path before work begins.
The equipment, electrical capacity, access, property layout, and local authority can change the scope from one Laurel address to another. AJ Long Electric confirms those conditions and the applicable coordination path before finalizing the proposal.
Cost depends on the equipment, electrical capacity, access, route, corrective work, and local coordination required at the property. AJ Long Electric provides a written estimate after the relevant conditions and project boundary are assessed.
Permit and inspection requirements depend on the address and the defined electrical scope. AJ Long Electric confirms the applicable path with the authority serving the property and states the included coordination in the written proposal.
Timing depends on the defined scope, safe access, equipment and material availability, property conditions, and any permit, inspection, utility, or other-trade coordination. AJ Long Electric confirms the anticipated sequence after the assessment.

Generally, yes. Federal Pacific Stab-Lok and Zinsco panels — common in West Laurel and South Laurel's midcentury homes — have a documented history of breakers that may fail to trip on a fault, and insurers increasingly flag them. AJ Long Electric replaces them with a modern 200-amp service ($3,500-$7,500) rather than reusing the equipment, brings grounding to current NEC, coordinates the Pepco meter pull, and permits through Prince George's County DPIE.
It can. The electrical permit always goes through Prince George's County DPIE, but Old Town Laurel sits in the city's historic district, so visible exterior service work can trigger City of Laurel preservation review. AJ Long Electric is used to replacing knob-and-tube and 60-amp fuse panels in these 19th-century homes without damaging period millwork or plaster, and handles both the county permit and the city review.
Typical Price Range: $3,500-$7,500 (200A); 400A quoted per project

Challenge
A West Laurel homeowner in a 1960s rancher discovered, during a home-insurance review, that their service was a Federal Pacific Stab-Lok panel — a type widely flagged for breakers that can fail to trip on a fault. They also wanted to add a generator-inlet hookup ahead of the next Patuxent-corridor storm season.
Solution
We replaced the Federal Pacific panel with a new 200-amp service, brought grounding and bonding to current NEC, and installed a transfer-switch/inlet hookup so a portable generator can power critical circuits during an outage. We coordinated the Pepco meter pull and permitted the work through PG County DPIE.
Result
The home traded a panel with a known safety reputation for a modern, properly grounded 200-amp service, gained code-compliant storm backup capability in the same visit, and cleared the insurer's concern — all on one permit and one mobilization.
