    Panel Upgrades & Heavy-Ups in Gaithersburg, MD - Pirro Electric

    Homeowners and property managers across Gaithersburg, Maryland rely on Pirro Electric for panel upgrades. Gaithersburg has one of the most varied building stocks in Montgomery County. Olde Towne Gaithersburg has early-1900s wood-frame houses with knob-and-tube remnants and later add-on wiring that was never brought up to a real standard. Montgomery Village, built mostly in the 1970s and 1980s, has whole clusters of townhomes with aluminum branch wiring and original panels, some Federal Pacific, now decades past their design life. Quince Orchard's larger single-family homes commonly still run on 100-amp services that were fine before central air, home offices, and EV chargers all landed on the same panel. Rio, Washingtonian, Crown, and Watkins Mill represent the newer end: mixed-use buildings and retail spaces that need frequent tenant fit-outs as businesses turn over. All of it runs through Montgomery County DPS permitting, with Pepco as the utility for service and meter work. Being headquartered here in Gaithersburg, this is the territory we know best.

    From Kentlands, Lakelands, Rio / Washingtonian, and Olde Towne Gaithersburg, 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.
