How long does a panel upgrade take?

Most residential 100A-to-200A heavy-ups are completed in a single day, with power off for roughly 4–8 hours.

Do I need a permit for a panel upgrade?

Yes - every jurisdiction in MD, DC, and VA requires a permit and final inspection for service-equipment work. We handle both.

How do I know if I have a Federal Pacific or Zinsco panel?

Federal Pacific Stab-Lok panels usually say 'FPE' or 'Stab-Lok' on the cover. Zinsco panels often have colored breaker handles (red, blue, green). Send us a photo and we'll confirm.

Are you licensed to do panel upgrades in Washington, DC?

Yes. Pirro Electric is fully licensed and insured to perform commercial and residential electrical work in Maryland, Virginia, and Washington, D.C., including Washington. We pull all required permits and coordinate inspections with the local jurisdiction on every job.

Do you handle aluminum wiring remediation in Washington?

Yes. Aluminum wiring remediation is one of our specialties for multi-unit buildings, condos, and single-family homes built in the late 1960s and 1970s throughout Washington and the broader DMV. We rewire to copper, replace outdated panels, and document everything for insurance carriers.

Panel Upgrades & Heavy-Ups in Washington, DC - Pirro Electric

Panel Upgrades in Washington, DC is a bread-and-butter call for Pirro Electric. Washington, D.C.'s housing stock is overwhelmingly pre-1950, meaning knob-and-tube remnants, undersized 60–100A services, original federal-style fuse panels, and aluminum wiring in mid-century apartment conversions. D.C. permitting and DCRA inspections add complexity that we manage end-to-end.

Recent Washington work includes rowhome rewiring with dcra permit coordination and service upgrades from 100a to 200a - and we cover every corner of the city, from Columbia Heights, Petworth, Brookland, and H Street. Every job is permitted, inspected, and backed by our Maryland, D.C., and Virginia licenses.
