Electrical Panel Upgrade & Replacement Service — Northern Virginia, Maryland & DC

The written quote defines the actual work: panel and breakers, any service or meter changes, grounding and bonding corrections, labeling, permits, inspection coordination, and any included utility work. A panel replacement does not automatically include a service-capacity increase, every branch-circuit repair, relocation, or finish restoration.

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.

Only the insurer can determine eligibility, coverage, or premium effects. We can provide factual project documentation for the homeowner to share with the carrier.

The authority serving the property checks the installed equipment, grounding and bonding, working clearances, labeling, and any service or meter work in the permit scope. AJ Long Electric confirms the inspection path before work begins and is present for the inspection when the jurisdiction requires it.

Future solar requires a separate review of the generation equipment, panel and bus ratings, connection arrangement, utility requirements, and adopted rules. An empty breaker space or a new 200-amp panel does not guarantee every future system will fit. Tell us about planned equipment so the current proposal can document what has been considered and what remains undecided.

Not necessarily. Circuit space and electrical capacity are different limits. A suitable subpanel or other approved distribution arrangement may add spaces, but it does not increase service capacity. We evaluate both limits before recommending the work.

Yes. A tripping circuit can need diagnosis of the circuit, connected equipment, or protective device rather than a complete panel replacement. Choose troubleshooting for an existing fault; diagnostic and repair work uses our published time-based rates. A planned panel installation receives a separate project quote.

Send the address, photos of the closed panel and accessible labels, any inspection report, and the equipment you want to add. Tell us about access restrictions and where the meter is located. Leave covers in place and do not touch damaged equipment.

Our published 200-amp planning range is $3,500–$7,500; 400-amp work is quoted per project. The final scope depends on service and meter conditions, access, required corrections, utility coordination, and finish work. Ask the written estimate to identify included work and exclusions.

Staff review the request and discuss the project before a date is confirmed. A required utility disconnect, permit, equipment availability, site access, and inspection sequence can affect timing. Tell us about essential equipment that depends on power so the planned interruption can be discussed in advance.

Estimates are free for every service. Scheduled estimate visits and written project prices are free. Diagnostic and repair work is a separately priced service. Our quoted electrical installations include a five-year workmanship warranty from completion. Parts and equipment carry their manufacturer warranties.
