York County, Maine
Licensed, insured electrical work for Sanford homes and businesses, with the owner on every job.
Sanford grew up along the Mousam River, where water power ran the Goodall mills downtown and a second cluster of factories in Springvale. Today it is a city of about 22,000 people and roughly 10,200 homes, from mill-era houses near the river to newer subdivisions on the outskirts. Goodnow Electric, a Westbrook master electrician licensed in Maine, serves the whole city: service and panel upgrades, EV chargers, generators, rewiring, lighting, and emergency calls at any hour, with the owner working on site.
Sanford's housing is older and denser than most of York County. Half of its homes were built before about 1975, the Census finds; roughly 23 percent predate 1940 and about 35 percent predate 1960, while only about 14 percent are from 2000 or later. The mill era left about 17 percent of homes in buildings of two to four units, and about 29 percent are rented. For wiring, that mix matters. Pre-war houses can still carry fuse panels, knob-and-tube circuits and cloth-jacketed cable, and many started life on 60- or 100-amp services. Multi-family buildings add shared meter banks and common-area circuits that have to be sorted out during any service change. About 5 percent of homes are mobile homes, which follow their own service and grounding rules.
Heating oil still warms about 63 percent of occupied homes in Sanford, per the Census; propane covers roughly 13 percent, wood about 5 and utility gas near 4. Electric heat, at about 12 percent, runs well above the 4 to 7 percent seen in Alfred, Lyman and North Berwick. Each oil boiler replaced by a heat pump moves heating load onto the electrical service, and the city's electrical permit form now lists mini-split heat pumps and EV chargers as their own line items. For home charging, Efficiency Maine takes $400 off a qualifying off-peak Level 2 unit.
Central Maine Power delivers electricity in Sanford, and the city's electrical permit asks for a CMP work order number whenever service work is involved. Big storms have shown what that grid faces. More than 400,000 Maine customers lost power in the October 2017 windstorm, some of them for longer than a week, a bigger weather outage than the 1998 ice storm; the December 2023 storm then left about 300,000 Maine outages. The Sanford Water District supplies Sanford and Springvale, but sump pumps, boiler controls, refrigerators and medical equipment still stop when the power does.
Two historic centers still shape the city. Downtown holds the Sanford Mills Historic District, the Thomas Goodall House, the Louis B. Goodall Memorial Library and Goodall Park, the roofed ballpark the family built in 1914. Springvale has its own former town hall and the Goodall Worsted Company alpaca mill on Water Street, added to the National Register in December 2025. When Burlington Mills closed Sanford Mills in the 1950s, it left 3,600 people out of work and about two million square feet of empty mill space. Brick mills, company-built worker housing and later ranches and capes are what an electrician walks into here.
Sanford runs its own electrical inspection. The Codes Office at City Hall, 919 Main Street, has an electrical inspector on staff, and the city's permit application states that work shall not be done without a permit, with a $75 minimum fee. Inspections need at least 24 hours' notice. The form itemizes services by amperage, sub-panels, generators with transfer switches, heat pumps, EV chargers and the joining of mobile and modular home sections. Goodnow Electric pulls the permit and schedules the inspections. Maine's Electricians' Examining Board has adopted the 2026 National Electrical Code, which governs work started from July 1, 2026.

“We had a major issue happen near Easter, we called multiple people, this company was right on ball calling us back. He is amazing, instead of making us feel insecure he assured us that we was in right direction, took time out of his own day to answer us after hours and even called back for a follow…”
