What to Expect from Our Electrical Service Upgrades Service
Your electrical service is the backbone of your entire home's power system, encompassing everything from the utility transformer connection through the meter base, service entrance cables, and main panel. When your home's electrical demands exceed the capacity of your existing service, you need a complete service upgrade -- not just a panel swap. AJ Long Electric performs comprehensive electrical service upgrades throughout Northern Virginia, coordinating directly with BGE for meter disconnects, reconnects, and service capacity increases. Many Northern Virginia homes built in the 1960s through 1980s still operate on 100-amp or even 60-amp service that cannot safely support modern electrical demands including EV chargers, heat pumps, electric cooking, home offices, and multiple high-draw appliances. Our licensed electricians upgrade service entrance cables, meter bases, weatherheads, grounding electrode systems, and main panels as a complete, integrated project. We handle all coordination with BGE, obtain permits from Fairfax County, Loudoun County, Prince William County, Arlington, or your specific jurisdiction, and ensure the installation meets current NEC standards. A typical service upgrade from 100A to 200A or from 200A to 400A involves replacing the service entrance conductors, upgrading the meter base, installing a new main panel, and verifying the grounding electrode system meets NEC 250 requirements. We complete most residential service upgrades in 1-2 days with minimal disruption. In Gambrills, we have seen how load-growth panel and sub-panel upgrades in 1990s-2010s waugh chapel and four seasons homes affects homeowners. That is why we take the time to assess your entire electrical system and recommend solutions that address both immediate needs and long-term reliability. Every electrical service upgrades project we complete in Anne Arundel County includes a thorough inspection, detailed documentation, and our commitment to your complete satisfaction.

Electrical Service Upgrades Questions from Gambrills Homeowners
What is the difference between a service upgrade and a panel upgrade?
A panel upgrade replaces just the electrical panel (breaker box) inside your home. A service upgrade encompasses the entire power delivery system from the utility connection to the panel, including service entrance cables, meter base, weatherhead, and main panel. A service upgrade is needed when you are increasing your total amperage capacity.
How much does a service upgrade cost in Northern Virginia?
A 100A to 200A service upgrade in the DC metro area typically costs $3,500-$6,000. A 200A to 400A upgrade runs $6,000-$12,000. Costs vary based on the distance from meter to panel, whether underground or overhead service, and specific utility requirements. We provide detailed quotes after a site assessment.
How long does a service upgrade take?
Most residential service upgrades take 1-2 days. Day one typically involves installing the new panel, service entrance cables, and meter base. Day two, if needed, involves BGE reconnection and final testing. You will be without power during portions of the work, but we minimize outage time.
Do I need BGE involved in my service upgrade?
Yes, BGE must disconnect and reconnect the meter for any service upgrade. They may also need to upgrade the transformer or service drop if you are increasing capacity significantly. We handle all coordination with BGE as part of our service.
What size service do I need for my home?
Most modern homes require at least 200-amp service. Large homes with multiple high-draw systems (EV chargers, heat pumps, electric cooking, pool equipment) may need 400-amp service. We perform a detailed load calculation based on your current and anticipated electrical needs to determine the right service size.
What makes electrical service upgrades in Gambrills different from other areas?
Gambrills homes are mostly large-lot and equestrian properties mixed with 1990s-2010s subdivisions like Waugh Chapel and Two Rivers, so we frequently encounter 200A services in newer construction, with older 100-150A panels on the larger established lots. The most common situation we address is accessory-structure subpanels and outdoor/well-pump circuits on larger Gambrills and Waugh Chapel lots. Permits for this work go through the Anne Arundel County Department of Inspections and Permits, and Anne Arundel County permit fees apply and are itemized; BGE coordination is built into the quote. That local knowledge means AJ Long Electric arrives prepared for the conditions specific to Gambrills rather than treating it like any other Anne Arundel County job.

Maintenance Tips for Gambrills Homeowners
Visually inspect your meter base and service entrance cables annually for signs of damage, corrosion, or weathering
Maintain 36 inches of clear access in front of your main panel at all times per NEC requirements
Keep vegetation trimmed away from overhead service entrance cables and weatherheads
Have your grounding electrode system checked every 5 years to ensure connections are tight and ground rods are intact
Report any utility-side issues (damaged service drop, leaning pole) to BGE promptly
Safety Warnings
•Service entrance cables carry lethal voltages directly from the utility and remain energized even when the main breaker is off
•Only licensed electricians should work on service entrance equipment -- contact with service conductors can be instantly fatal
•A damaged or corroded meter base can cause arcing and fire at the service entrance
•Never bypass or modify the meter or meter base -- this is illegal and extremely dangerous

Electrical Service Upgrades in Gambrills Case Studies
See how we have helped homeowners across Northern Virginia with their electrical service upgrades in gambrills needs.
60-Amp to 200-Amp Service Upgrade in Pre-War Colonial
colonialColonial home in Falls Church, Fairfax County
Challenge
A 1948 colonial still had its original 60-amp service with a fuse box and cloth-insulated service entrance cables. The homeowner wanted to install central air conditioning and a Level 2 EV charger, but the 60-amp service could barely handle the existing load. BGE had flagged the corroded weatherhead during a routine inspection.
Solution
AJ Long Electric performed a complete service upgrade from 60A to 200A, replacing the weatherhead, service entrance cables, meter base, and main panel. We installed a new Square D 200-amp panel with 40 spaces, upgraded the grounding electrode system with two new ground rods, and coordinated with BGE for the service drop reconnection.
Result
The home now has modern 200-amp service with ample capacity for the new central AC, EV charger, and future additions. The homeowner's insurance premium dropped after the fuse box was eliminated, and the property value increased with the modernized electrical system.
Overhead to Underground Service Conversion
townhomeTownhome community in Centreville, Loudoun County
Challenge
A townhome community was converting from overhead to underground utility service as part of a neighborhood improvement project. Each unit needed a new underground service lateral, updated meter base, and coordination with both the HOA and BGE. The homeowner took the opportunity to upgrade from 100A to 200A service simultaneously.
Solution
We installed a new underground-rated meter base, ran the service entrance conductors through PVC conduit to the underground lateral termination point, and upgraded the main panel from 100A to 200A. We coordinated with the HOA's general contractor for trenching and with BGE for the underground service connection.
Result
The overhead service lines and weatherhead were eliminated, improving the unit's appearance and eliminating storm damage risk to the service entrance. The upgraded 200-amp service provides capacity for the homeowner's EV charger and planned kitchen renovation.
Storm-Damaged Service Entrance Emergency Replacement
split-levelSplit-level home in Springfield, Prince William County
Challenge
A large tree branch fell during an ice storm and tore the service entrance cables and weatherhead from the side of the house, leaving the family without power. BGE disconnected the service at the pole for safety, but the homeowner's existing 100-amp service components were too damaged to simply reattach -- the meter base was cracked and the service entrance cable insulation was shredded.
Solution
AJ Long Electric responded within hours, coordinating with BGE for an emergency service restoration timeline. We replaced the weatherhead, mast, service entrance cables, and meter base, upgrading from 100A to 200A service since all components were being replaced anyway. We expedited the permit through Prince William County's emergency process.
Result
Power was restored within 36 hours of the initial damage, with the home now upgraded to 200-amp service. The emergency permit was closed with a passed inspection, and the homeowner gained significant capacity improvements from what started as a storm damage repair.
200-Amp to 400-Amp Service for Full Home Electrification
estateEstate property in Leesburg, Arlington County
Challenge
The homeowners were fully electrifying their 6,000 sq ft estate, replacing a propane furnace with dual heat pumps, converting a gas range to induction, adding three EV chargers for their vehicle fleet, and building a heated pool with an electric heat pump. A detailed load calculation showed their 200-amp service would be approximately 40% over capacity with all planned additions.
Solution
We upgraded the service to 400 amps with a CT metering cabinet, two 200-amp main panels, and coordination with BGE for a transformer upgrade on the utility side. The underground service lateral was upsized with 500 MCM aluminum conductors, and we installed a comprehensive grounding electrode system with ground rods, Ufer ground, and water pipe bond.
Result
The estate now operates entirely on electricity with 400-amp service providing ample capacity for all systems. The homeowner eliminated their propane deliveries entirely, and the three EV chargers can all charge simultaneously overnight without load concerns. BGE confirmed the transformer upgrade supports the increased demand.

By Home Type
Electrical Service Upgrades in Gambrills by Housing Type
Different home styles have unique electrical characteristics. Select your housing type to see specific considerations.
Colonial Homes
Common Issues
Original 100-amp or 60-amp service from 1950s-1970s construction is grossly undersized for modern demands
Service entrance cables routed through interior walls may contain deteriorated cloth insulation
Meter base and weatherhead mounted on aging wood siding may have moisture damage behind the equipment
Special Considerations
Colonial homes in Falls Church, McLean, and Vienna often have service entrance components that are 40-60 years old with deteriorated insulation and corroded connections. The service entrance cables frequently route through finished interior walls from the weatherhead to the basement panel, requiring careful planning to replace without damaging plaster or drywall. We coordinate with BGE to minimize the time the home is disconnected during the upgrade.
