    Panel Upgrades & Heavy-Ups in Silver Spring, MD - Pirro Electric

    Homeowners and property managers across Silver Spring, Maryland rely on Pirro Electric for panel upgrades. Silver Spring is dense with mid-century single-family homes and 1960s-80s multi-unit apartment and condo buildings. Woodside and Forest Glen have early-1900s to 1940s houses with knob-and-tube remnants and two-prong ungrounded outlets still in daily use. Four Corners and Kemp Mill have a lot of 1950s-60s ramblers wired with aluminum branch circuits and running on original, undersized panels. The apartment and condo towers around Downtown Silver Spring and White Oak, many built in the 1960s through 1980s, have aging shared feeders and meter banks that need upgrading as units turn over, plus tenant fit-out work in the ground-floor retail. All of this runs through Montgomery County DPS for permitting, with Pepco as the utility.

    From Downtown Silver Spring, Woodside, Four Corners, and Takoma Park (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."
