One public range, different scope factors
Panel-upgrade pricing in Leesburg splits roughly into two patterns based on home era and location:
- Old & Historic District homes (downtown Leesburg). Top of the $3,500–$7,500 range for full service replacement. Includes BAR coordination, careful wall protection, and often new service mast on overhead-service homes.
- Lansdowne, Potomac Station, Beacon Hill, Crescent Place. $3,500–$7,500 for a standard 200A upgrade. Underground service and the absence of BAR review can simplify the documented scope.
The $3,500–$7,500 public band includes the defined Loudoun County permit, fireman's disconnect, basic surge protection, utility coordination, and inspection scope. BAR review, wall construction, service routing, equipment, and access are evaluated for the address; the written proposal identifies any condition-specific scope and schedule dependencies.
The historic-district considerations
Downtown Leesburg's Old & Historic District covers most of the area between East Loudoun, Edwards Ferry, Royal, and Memorial Drive. Homes in this district have:
- •Pre-1950s construction common (some pre-1850s)
- •Original electrical service often 60A with partial upgrades over the decades
- •Knob-and-tube wiring still in service in some basements and attics
- •BAR-restricted exterior modifications (meter base relocation, service mast changes)
- •Plaster walls and lath construction that require careful protection during interior work
We've done historic-district electrical work in Leesburg for years. The BAR process is manageable as long as you plan for it; we handle the application and coordination.
Frequently asked questions
What does a panel upgrade cost in Leesburg?
A code-compliant 200-amp upgrade in Leesburg follows the Northern Virginia public range of $3,500–$7,500. Historic district homes near the courthouse and downtown often run at the upper end because of building-age constraints; final scope is documented after the on-site review.
Does the Leesburg Historic District have special requirements?
Exterior-visible work in the Old & Historic District may require Town of Leesburg Board of Architectural Review (BAR) review. We confirm the address and proposed exterior scope, coordinate the applicable application, and set the project schedule from the Town's current review process and any requested revisions.
What about pre-1950s homes?
Leesburg has a substantial inventory of pre-1950s homes — many on the National Register. These often have knob-and-tube wiring still in service, original 60-amp electrical service, and modified meter installations from decades of partial upgrades. A typical 200A service replacement follows the $3,500–$7,500 public range; wall construction and BAR coordination are documented in the project scope.
What permitting do you do in Leesburg?
Leesburg is in Loudoun County, so panel upgrades go through Loudoun County Building & Development permitting. AJ Long Electric files the electrical permit under the company contractor license. Old & Historic District properties may also require Town of Leesburg BAR review; timing depends on the applicable authority's current queue.
Do you work in Lansdowne and Potomac Station?
Yes — Lansdowne (1990s–2000s subdivision) and Potomac Station (similar era) both have homes with original 200A service and minimal historic-district complications. Most work in these neighborhoods is capacity additions (sub-panels for EV chargers, finished basements, solar inverters) rather than full panel replacements. Same Loudoun County permitting.
What about backup power?
Common request in Leesburg — large lots, occasional storm outages, and a market that values backup power. A portable generator hookup — inlet plus listed transfer or interlock equipment — typically runs $900–$2,500; the generator itself is a homeowner purchase. Listed battery systems typically run $2,500–$6,000 for portable setups and $6,000–$15,000+ for whole-home integration. These often pair naturally with a panel upgrade.
