Edward J. Mayer Electrician LLC — trading as EJM Electrical — is a residential electrician based near Onset/Wareham on the Upper Cape, run by owner Ed Mayer with foreman Matt appearing repeatedly alongside him in customer accounts. The Better Business Bureau listing describes a broad residential scope: service upgrades, whole-house generators with interlock kits, service calls, new-construction and renovation wiring, TV mounts and low-voltage wiring.
Twenty-five Google reviews, all five stars and dated across 2025 into 2026, describe a business many customers have used repeatedly for years — several cite 5-, 6-, 7-, 8- and even 10-year relationships spanning multiple homes. The recurring work described is specific: EV charger installs (including a Tesla Wall Connector on a tricky multi-level layout), whole-house generator installs with panel interlocks, subpanel additions, rewiring sections of homes, pool electrical, doorbell rewiring, and swapping old fixtures for LED lighting. One reviewer detailed a Level II EV charger install where Ed explained that a $1,000 load balancer the charger's own install portal called for wasn't actually needed and skipped it — a concrete example of the honesty reviewers describe more generally across the set. A large East Falmouth home renovation drew praise for Ed staying onsite throughout and for foreman Matt's knowledge and communication. Across the reviews the consistent themes are prompt scheduling, clear communication, arriving when promised, and fair, transparent pricing — several reviewers explicitly contrast that reliability with "others in the industry." A Better Business Bureau review from the same period echoes the same read: on-time, well-communicated, dependable, polite work.
The BBB profile lists an A+ letter grade but states the business is not accredited with the Bureau — two separate facts worth knowing rather than reading it as one unqualified endorsement.
For anyone on the Upper Cape needing EV charger installation, a whole-house generator, a panel or subpanel upgrade, or general residential electrical work, this is a repeatedly-hired electrician with a specific, verifiable multi-year track record rather than generic praise.
