Juan D. Guerrero

Juan D. Guerrero is a one-name electrical contractor working out of 106 Tenney St in Methuen, Massachusetts, and the clearest picture of what he does comes from the permits pulled under that name rather than from anything customers have written. Building-permit filings show 18 permitted projects, concentrated in residential electrical work across Methuen, Haverhill, Merrimac and Rowley between 2019 and 2025. That is a steady, house-by-house pattern in one corner of the Merrimack Valley over roughly six years. What is missing is any customer voice. BuildZoom, the permit directory carrying the listing, states plainly that it has received no reviews for this electrician, so there is nothing from people who actually hired him to weigh. For that reason no rating is published here at all rather than a guessed one. Licensing is the thing to settle before you call. The only licence attached to this name on that listing is a Maine 'Electricians Helper' registration, #HP20037556, inactive and expired since February 2014 — a different state's board and a helper-grade credential, not a Massachusetts electrician's licence, and it should be read neither as this business's active credential nor as a lapse on his part. BuildZoom itself says it has not been able to verify an active licence, which is why its score for the listing sits at zero. If you are weighing him for residential electrical work in Methuen or the towns around it, ask directly for his Massachusetts electrician's licence number, confirm it with the state's Board of State Examiners of Electricians, and ask for references from recent jobs.
