## The honest read

Mr Cape Electrician is a residential electrical contractor based in Barnstable, serving customers across Cape Cod. Its Massachusetts electrician license (No. 55688) is verified active by the state licensing board, held by Adair Martins; Adair and lead technician Sean are both named repeatedly, across years and across platforms, in customer reviews.

The business has built a deep, mostly excellent track record: 54 reviews collected across nine platforms since 2022, the large majority five-star, including 6 in the last six months with none of those recent six negative. Customers consistently praise fast, clear communication — same-day or next-day callbacks, texted arrival windows, and steady updates — alongside tidy job sites. The recurring, specific praise centers on panel and service upgrades (several reviewers describe 100-amp to 200-amp service upgrades and new sub-panels run out to sheds or barns), whole-house rewiring and code-compliance repairs in older Cape homes, recessed and decorative lighting installs, and circuit-breaker or outlet troubleshooting. Several homeowners describe hiring the company more than once over multiple years for different projects, a sign of durable trust rather than a single good visit.

Before booking, it's worth knowing about one detailed negative account: a December 2022 Angi review described a complex, multi-day wiring and heating job the crew left unfinished, including mislabeled wiring and several weeks of unreturned calls and emails before the customer's concerns were addressed. That review is now several years old and is the lone detractor amid otherwise uniform praise, but it's worth asking directly how the company handles scope changes and post-job follow-up if your project is unusually large or complex. Also worth noting: the reviews shown on Angi and HomeAdvisor are byte-identical — the same ten reviews and 4.7 rating appear on both — so they read as one data point, not two independent ones.

For straightforward residential electrical work — panel upgrades, rewiring, lighting, and troubleshooting — this is a well-reviewed, licensed Cape Cod electrician with a long run of specific, credible praise. For a large or unusually complicated job, it's reasonable to confirm upfront how the company scopes bigger projects and how quickly they respond if something needs revisiting afterward.

**Strengths:**
- Fast communication — reviewers repeatedly cite same-day or next-day response
- Licensed electrician — MA license 55688 verified active, held by Adair Martins
- Clean job sites — reviewers note crews leaving work areas spotless
- Panel upgrades — repeatedly cited for 100A-to-200A service and sub-panel installs
- Repeat customers — several reviewers describe hiring them multiple times over years

**Concerns:**
- Unfinished complex job — a 2022 review described incomplete heating-related wiring work
- Slow complaint follow-up — same review cited weeks of unreturned calls and emails

**Where sources disagree:**
- Angi and HomeAdvisor show byte-identical review sets (same 10 reviews, same 4.7 rating) — not independent corroboration of each other.
- Angi/HomeAdvisor list the business location as Harwich, MA while the verified base and BBB/registry address is Barnstable, MA — same business (confirmed by repeated named-technician references), likely a directory geocoding artifact rather than a second location.
