Generator Install in Bethesda, MD is a bread-and-butter call for Pirro Electric. Bethesda's housing stock skews older and higher-end, with many mid-century homes carrying aluminum branch circuits, undersized 100-amp services, and outdated panels. On the commercial side, downtown Bethesda's older office buildings frequently need lighting retrofits, EV-readiness, and tenant fit-out work.
Recent Bethesda work includes whole-home generator installs - and we cover every corner of the city, from Bradley Hills, Burning Tree, Glen Echo Heights, and Westmoreland Hills. Every job is permitted, inspected, and backed by our Maryland, D.C., and Virginia licenses.

What Customers Say
Excerpts from verified Google reviews of Pirro Electric.
"Pirro re-wired my whole townhouse, updated the panel, and replaced every outlet and switch. Professional, friendly, and on time. Couldn't ask for a better company."

Google Review · Verified Homeowner"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."
