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.

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

Do you handle aluminum wiring remediation in Tysons?

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 Tysons and the broader DMV. We rewire to copper, replace outdated panels, and document everything for insurance carriers.
