Electricians in Portland, Maine

Portland is Maine's largest city and one of its oldest, and its electrical needs are just as varied as its neighborhoods. From the Victorian-era homes lining the West End and Munjoy Hill to the restaurants and boutiques packed into the Old Port, we handle the full spectrum of wiring challenges. Knob-and-tube replacement, 200-amp panel upgrades, and code-compliant rewires are typical needs in a housing stock this old.

The East End and arts district have seen a wave of renovations in recent years, turning older buildings into modern living spaces. That means bringing outdated electrical systems up to current code while preserving the character of these historic structures. We work closely with homeowners and contractors to plan efficient, safe upgrades that meet both building requirements and design goals.

Portland's commercial corridor along Congress Street and the waterfront keeps us busy with tenant fit-outs, lighting installations, and service upgrades for growing businesses. Whether you own a Munjoy Hill triple-decker or run a shop in the Old Port, Goodnow Electric is a short drive away from our Westbrook headquarters and ready to help.

Portland has burned to the ground four times, most famously in the Great Fire of 1866, which leveled some 1,800 buildings and left ten thousand residents homeless. The city rebuilt in brick — which is why the Old Port's Victorian commercial blocks look the way they do — and adopted the motto "Resurgam," Latin for "I shall rise again," with a phoenix on the city seal. Up on Munjoy Hill, the 1807 Portland Observatory still stands as the last surviving maritime signal tower in the United States.

All that 19th-century rebuilding means Portland carries one of the oldest housing stocks in Maine. Homes wired generations ago — some still with knob-and-tube or 60-amp fuse panels — were never designed for heat pumps, EV chargers, and modern kitchens. That calls for careful old-house rewiring and panel work — the kind of job Goodnow Electric handles for Portland homeowners.

Portland had 68,408 residents at the 2020 census, which makes it Maine's largest city by a wide margin. Electrical permits here are issued by the city's Permitting and Inspections Department at 389 Congress Street, which takes applications through an online portal, and Central Maine Power is the utility for service disconnects and meter work. Since July 1, 2026, new electrical installations across Maine follow the 2026 National Electrical Code as adopted by the Maine Electricians' Examining Board, which matters for anything from a kitchen remodel to an EV charger.
