Pirro Electric handles commercial electrical for homeowners, businesses, and property managers in Gaithersburg, MD. Work is scoped on site, quoted in writing, permitted, and inspected before we call it done. Typical scope: new construction and tenant build-outs, office circuitry, data, and lighting installation, and underground wiring and electric meter setup.
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.
Twenty Years Wiring DC-Area Commercial Properties
Pirro Electric has served as a commercial electrical contractor across Washington, D.C., Montgomery County, and Northern Virginia since 2003. From single-tenant retail fit-outs to multi-building portfolios, our master electricians plan, permit, and execute electrical infrastructure that passes inspection the first time.
We work directly with property managers, general contractors, and building owners - so scope, schedule, and budget stay aligned from day one. Every job is insured and backed by Maryland, D.C., and Virginia electrical licenses.
Tenant Improvements & New Build-Outs
Whether you're delivering a vanilla shell or a turnkey buildout, we handle the full electrical scope: branch circuits, lighting, dedicated equipment circuits, low-voltage rough-ins, panel additions, and final trim. We coordinate with HVAC, plumbing, and IT trades so your space opens on time.
Common tenant work includes office and medical fit-outs, restaurant kitchens and hood circuits, retail lighting, and warehouse high-bay installations.

What Affects the Price of Commercial Electrical in Gaithersburg
Every quote is written after an on-site look. These are the variables that move the number:
- Project size - number of circuits, fixtures, and panels
- Permit and inspection fees by jurisdiction
- After-hours or weekend work to avoid tenant disruption
- Existing infrastructure condition (aluminum wiring, FPE panels, undersized service)
- Coordination with other trades on active construction sites
Local Conditions We Work Around in Gaithersburg
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.
Gaithersburg Housing Stock
A mix of every era: 1900s Olde Towne, 1960s-70s split-levels, 1990s Kentlands new-urbanist, 2000s Lakelands and Quince Orchard custom homes, and 2010s-plus Crown and Watkins Mill mid-rise. Aluminum branch wiring shows up in scattered 1970s subdivisions.
Permits & Utility Coordination in Gaithersburg
The City of Gaithersburg has its own permit office running in parallel with Montgomery County DPS, so we file based on the address. Crown and Washingtonian Center commercial spaces require landlord coordination and often after-hours work windows.
