Plymouth gets its electricity from Plymouth Utilities, a city-owned utility, and its housing ranges from 19th-century homes near the Mullet River to newer subdivisions on the edges of town. More than one in five Plymouth homes was built before 1940, so knob-and-tube wiring, fuse boxes, and ungrounded outlets still turn up. Mr. Holland’s licensed electricians help Plymouth homeowners with rewiring, panel upgrades, EV chargers, Generac generators, lighting, and 24/7 emergency electrical repair. Call (262) 223-3786.
