The wiring in a house here usually tells you when it was built and when it was winterized. Cottages and boarding houses from before 1940 may still have knob-and-tube circuits in the walls and attic, often spliced into later cable when a kitchen or bath was added. Houses from the 1940s through the 1960s tend to have cloth-sheathed cable and ungrounded two-prong outlets. Some homes from the late 1960s and early 1970s were wired with aluminum branch circuits, which need proper connectors at every device. The condominiums and houses built since 1980, about half the stock, have grounded circuits but may be short on outlets and lack the arc-fault and ground-fault protection current code expects.
Remodeling is where old and new meet. Winterizing a cottage usually means opening walls anyway, which is the cheapest moment to replace old circuits and add outlets where extension cords used to run. Kitchens and bathrooms need GFCI protection, bedrooms and living areas need AFCI protection, and a new heat pump or electric range needs its own dedicated circuit. Because Old Orchard Beach issues its own electrical permits, the work is inspected by the town before walls close. Owners who rent seasonally or year-round also hold a town business license, and clean, documented wiring makes that relationship with the town simpler.
Two local conditions deserve attention in any wiring plan. Basements that took water in the January 2024 flooding may have outlets, cable or junction boxes that were submerged, and anything that sat in salt water should be replaced rather than dried and reused. Outdoors, receptacles should be weather-resistant, GFCI-protected and fitted with in-use covers, because spray and sand reach farther inland than most people expect. For troubleshooting, such as a breaker that trips every time the space heater and toaster run together, Goodnow Electric traces the circuit and gives a free written estimate before any repair. Adding a bedroom or finishing an attic in a cottage is also the moment to plan heat, lighting and outlet circuits together, so the new space does not end up on a single overloaded run borrowed from the floor below.
