O'Keefe Electric Co

O'Keefe Electric Co serves Londonderry from 547 Mammoth Rd, with recent customers describing generator installation, can-light work, and efficient electrical repairs. Google lists 4.6 stars from 7 ratings, while the company's public footprint remains small at four written reviews spanning 2023–2026. A March 2026 customer praised Chad, Kyle, Ethan, and Dylan after a generator installation and added can lights, calling the crew professional, accommodating, quick, and efficient. A July 2025 review similarly described the team as responsive, quick, professional, and thorough while crediting Chad and Kyle with resolving electrical issues. An older January 2023 review praised Conor's professionalism and work quality. The written history also includes a January 2023 complaint from a customer who received no return call after leaving a message. That is worth asking about when arranging an estimate or service call, especially if timing is important. O'Keefe Electric looks suited to homeowners seeking generator installation, lighting additions, and general electrical repairs in the Londonderry area. Confirm the scope, response expectations, and scheduling window before work begins; the available reviews support a positive recent read but are still a limited sample.
