    Panel Upgrades & Heavy-Ups in Fairfax, VA - Pirro Electric

    Homeowners and property managers across Fairfax, Virginia rely on Pirro Electric for panel upgrades. Fairfax's huge stock of 1970s-80s single-family homes and townhomes in areas like Fair Oaks, Oakton, and neighborhoods near Fairfax City carries a lot of aluminum branch wiring, original Federal Pacific panels, and 100-amp services that are now overloaded by EVs, added HVAC, and home offices. Old Town Fairfax has an older core of homes that mix knob-and-tube remnants with later aluminum-era rewiring, so it's not unusual to find both problems in one house. Commercial stretches along Route 50 and Route 29, plus the Mosaic District area near Merrifield, generate steady tenant fit-out and lighting retrofit work as retail and office space turns over. Fairfax County issues most electrical permits here, with Dominion Energy as the utility for the majority of the county and NOVEC serving parts of western Fairfax, so we confirm which utility applies before scheduling service work.

    From Fairfax City, Mosaic District (Merrifield, adjacent), Fair Oaks, and Burke (adjacent), our licensed electricians deliver the same permitted, code-compliant work that has kept us in business across the DMV since 2003. 200-amp upgrades, heavy-ups, sub-panels, and Federal Pacific & Zinsco replacements - done to code and inspected.

    "If you're thinking of going with Pirro - do it. You won't be sorry. I run a medium-sized HOA and wouldn't use any other company for our electric."
