# JM Electrical Company, Inc

**Trade:** Electrical · **Address:** 471 Broadway, Lynnfield, MA 01940, USA · **Phone:** (781) 581-3328 · **Website:** http://jmelectrical.com/ · **Languages:** English

**Rating: 3.1/5** (low confidence) — from 4 reviews across 5 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low.

## The honest read

JM Electrical Company is a Lynnfield-based commercial electrical contractor that's been at it since 1985 — the company describes itself as working with building automation and mechanical contractors across Greater Boston on controls, instrumentation, power and energy-solutions projects, the kind of behind-the-walls work that doesn't always show up as a routine service call.

What third parties have said backs that longevity up. A 2026 article marking the company's 40-year milestone credits it with roughly 25,000 completed projects and a national ranking from the National Electrical Contractors Association as the ninth-safest electrical contractor in the country. The customer record, while small, is consistently positive across several years: a 2023 Angi review called the service prompt, efficient and neat; in a 2021 review, a homeowner walked through a Google Nest installation and called the work knowledgeable and prompt, while another 2021 review described a quick office job as efficient and effective; a 2022 review from a Dorchester customer praised professional work and a fast appointment. Google shows 4.2 stars from 11 ratings and Angi shows 5.0 from 4.

There isn't much to flag before calling — the written record is short but clean. Given the commercial-controls focus described on its own site, it's worth confirming whether a smaller job like a single install or office repair fits alongside its larger mechanical-contractor work.

**Strengths:**
- Decades in business — self-reports operating in Lynnfield since 1985
- NECA safety ranking — named ninth-safest electrical contractor nationally
- Prompt, professional reviews — customers describe quick, neat, efficient work
