Pirro Electric handles panel upgrades for homeowners, businesses, and property managers in Bowie, MD. Work is scoped on site, quoted in writing, permitted, and inspected before we call it done. Typical scope: 100-amp to 200-amp service upgrades ("heavy-ups"), federal pacific stab-lok panel replacement, and zinsco panel replacement.
Bowie's massive Levitt-built Belair neighborhood (early 1960s) is one of the largest concentrations of aluminum branch wiring and Federal Pacific panels in the DMV. We do a steady stream of remediation work and service upgrades there, plus modern commercial fit-out around the Town Center.
When You Actually Need a Panel Upgrade
A 'heavy-up' - moving from 100-amp to 200-amp service - is one of the most common requests we get. You typically need one if you're adding an EV charger, a heat pump or mini-split, a hot tub, an addition, or if your existing panel is full and there's no room for new circuits.
If your panel is a Federal Pacific Stab-Lok or a Zinsco, the answer is simpler: replace it. Both panels have documented histories of breakers failing to trip during overcurrent - a known fire hazard and one that most insurers now flag during inspection.
Why Pirro Electric for Panel Work
Panel work is some of the highest-stakes residential electrical you can hire out - bad workmanship can quietly create fire hazards for years. We're licensed master electricians in MD, DC, and VA, fully insured, and we pull permits on every panel swap. No exceptions.
