Brunswick's houses were wired in waves. The oldest homes near the Bowdoin campus and the Federal Street Historic District can still hide knob-and-tube circuits in walls and attics, often spliced into later cloth-sheathed cable and two-prong ungrounded outlets. Houses from the 1950s through the 1970s usually have early plastic-sheathed cable but too few circuits and no ground-fault protection in kitchens or baths. Some homes from the late 1960s and 1970s used aluminum branch wiring, which needs proper connectors at every outlet and switch. Roughly 27 percent of the town's housing has been built since 2000 and is generally in better shape, though finished basements and additions often outgrow the original panel.
Remodels are where these layers surface. Opening a kitchen wall in a Federal Street house or a midcentury cape often reveals a mix of eras, and current code expects GFCI protection near water and AFCI protection on most living-space circuits in the rooms being worked on. Brunswick treats new dwelling units, primary or accessory, as permitted projects with their own review and fees, so an accessory apartment over a garage or in a converted barn needs its own circuits, smoke and carbon monoxide alarms, and a clear look at whether the existing service can carry a second household. Converting an attached barn or ell, common on older in-town lots, also means checking the old feeders that were run out there decades ago for a workbench and a light.
Goodnow Electric handles rewiring, new circuits, outlets and switches, GFCI and AFCI upgrades, troubleshooting and the wiring for additions and renovations, with the owner on site for every job. Brunswick requires an electrical permit whenever electrical work is done, and the work must be performed by a licensed Maine electrician unless the owner-occupant does it. For work beginning on or after July 1, 2026, the 2026 National Electrical Code applies statewide. For older houses, a written estimate after a walk-through is the best way to learn what is behind the plaster before a remodel budget is set.
