Verified record
C.M. Joy Company is a Kingston electrician whose calendar reads like a tour of the South Shore's harder electrical and HVAC jobs — panel upgrades, ductless mini-splits, generator installs, underground service conversions — with Chris Joy's name attached to nearly every one personally. The volume here is unusual: 68 reviews since 2024, and 54 of them landed in just the last six months, all positive. The specifics repeat in a way that reads as consistent rather than coincidental. A Kingston homeowner called him on a Sunday after a snowstorm, when a passing Eversource vehicle sheared off their electrical service — he was on site within the hour to get power restored. An apartment-building owner had him tear out old unpermitted wiring and bring the unit up to code, work neat enough that the subcontractors on the job said they'd never seen it done better. Multiple mini-split and ducted heat-pump installations come up by name, including one job where, per the customer, a state energy-program representative commented favorably on the clean work. What stands out beyond the electrical work itself is who's doing the recommending: several reviewers identify themselves as electricians, contractors, or real estate agents who refer their own clients to him, one saying flatly that Chris is "the only electrician I trust" for both high-end and small service jobs. Pricing comes up often and consistently favorably — quoted prices held, no surprise add-ons, and repeat customers across "several properties" and, for some, over 15 years. There isn't a documented complaint anywhere in the record to weigh against this. The one thing worth asking before booking, simply because the volume of work is real: confirm his schedule and lead time given how much he's clearly in demand.
