Pirro Electric brings 23 years of Maryland electrical experience to every panel upgrades job in Annapolis. Downtown Annapolis is a historic district with 18th–19th century homes, brick walls, and tight permitting through the Historic Preservation Commission. Waterfront properties also require careful attention to GFCI protection, marine-grade wiring, and storm-driven outage prep.
On any given month you'll find our trucks handling historic downtown rewiring (hpc coordination) and marine & dock electrical for waterfront homes across Downtown Annapolis, Eastport, Murray Hill, and West Annapolis. We pull permits in Annapolis, schedule inspections, and walk you through the work so nothing gets left to guess.
