# Jonathan Hall Electrician - Cape Cod & Islands Electrician

**Trade:** Electrical · **Address:** 149, Marstons Mills, MA 02648 · **Phone:** (508) 419-7800 · **Website:** http://www.jhallelectric.com/ · **Languages:** English

**Rating: 4.7/5** (high confidence) — from 32 reviews across 4 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.
100% of sentiment-scored reviews read net-positive. Last 6 months: 2 reviews, 0 negative.

## The honest read

Jonathan Hall Electrician is an owner-operated electrical business in Marstons Mills that works across Cape Cod, handling everyday residential and commercial electrical work plus generators, home theater, smart lighting and security cameras.

The review record is small but unusually consistent: 32 reviews from 2022 to 2026, all five stars, with a 5-star Google average across 53 ratings. What makes it read as real rather than generic is that customers name the people - Jon himself, and technicians Tim and LJ - and describe specific jobs across years.

The recurring theme is speed and diagnosis. In a 2024 review a homeowner who called out of the blue about a short that tripped a kitchen breaker heard back from the office the same day and had the fault separated the next; another 2024 reviewer got next-day service and says Tim found and fixed a problem they did not know they had. In August 2026 a repeat customer described replacing a failing well-pump switch and outlet and adding a power meter and smart relay so the pump could be monitored.

Customers also consistently mention tidiness and explanation - crews cleaning up after themselves and walking homeowners through the work in plain language - and one 2024 reviewer singled out scheduling that communicates immediately when something has to change.

What to ask about is scope and paperwork rather than workmanship: the business publishes no licence number on its own site, so ask for the master electrician licence number and confirm it against the state registry, and get the estimate in writing - the site offers a free estimate but the reviews rarely discuss pricing beyond calling it reasonable.

**Strengths:**
- Same-day callbacks — reviewers report replies the day they called
- Fault diagnosis — technicians traced shorts and unknown faults quickly
- Clean work — customers repeatedly note tidy, explained jobs
- Named crew — Tim and LJ recur across four years of reviews

**Concerns:**
- Single-platform record — all 32 reviews sit on Google
- No published licence — the site prints no electrician licence number

**Where sources disagree:**
- The business publishes no licence or registration number on its own website, and no state registry record appears in this packet, so its credentials are neither confirmed nor contradicted here - confirm the master electrician licence with the Massachusetts Board of State Examiners of Electricians before hiring.
- The five-star run is deep rather than suspicious: bodies vary from one line to several paragraphs, name three different workers, describe distinct jobs (a well pump control, a foyer lantern and wireless switch, an outdoor short, a Covid-era time-and-materials job) and span 2022 to 2026 - the shape of a small firm's real customer base.
