Cory Oak Electric — listed formally as Cory J. Oak Electric LLC — is a one-man electrical contractor working out of 19 Naugus Ave in Marblehead. The business describes itself as veteran owned and operated with 19 years in the trade, and the work it advertises is bread-and-butter residential electrical: wiring and panel upgrades, and installing or repairing switches, outlets and fixtures. What sets this profile apart from most thin ones is that the permit record does the talking. Town building departments show 26 permitted projects, eleven of them in the last three years, and the addresses read like a Marblehead route sheet — Glover Sq, Waldron St, Naugus Ave, Overlook Rd, West St, Atlantic Ave, Lafayette St, Hathaway Rd, Seaview Ave, Pond St, Elm St — with occasional jobs out to Danvers, Beverly, Groveland and Burlington. The two permits that carry a written scope are small and domestic: an exhaust fan, light and smart switch with an arc-fault breaker in Danvers in March 2023 at $800, and kitchen countertop circuits for a disposal and microwave in Beverly in February 2019 at $1,200. That is a real, verifiable pattern of pulling permits for small residential electrical work, and it is worth more than any badge. What is entirely absent is customer feedback. BuildZoom holds no reviews, and Angi states outright that the pro is new on both Angi and HomeAdvisor with none written yet. So there is no independent read on how the work turns out, how communication goes, or how pricing lands — you would be relying on your own references. One thing to disregard: BuildZoom's licence block claims it verified in September 2023 that this contractor "does not need a license to be a electrician in Massachusetts." That is wrong — Massachusetts licenses electricians through the state Board — and the same page contradicts itself with a "Verified License" badge in its header. Ask directly for the electrician's licence number and check it with the Division of Occupational Licensure, and ask for the certificate of insurance too. For a Marblehead homeowner with a panel upgrade, a fixture swap or added circuits, this is a local tradesman with a documented permit history in exactly that kind of work. Confirm the licence and insurance yourself, ask for a couple of recent neighbourhood references, and get the price in writing before starting.
