K Sampson Corp.

K Sampson Corp. runs out of Braintree doing standard residential and commercial electrical work, but its own list of certifications leans hard toward newer territory: Tesla Powerwall and EV charging, plus Enphase battery and bi-directional EV charging installs. That's a specific niche for a small Massachusetts electrical shop, backed by OSHA 10 and NFPA hot-work safety credentials. The company describes its territory as covering Eastern Massachusetts and Cape Cod, and it's listed as a member of the Braintree Chamber of Commerce. No independent customer reviews turned up anywhere yet, so there's no outside track record to weigh against those self-reported credentials. Anyone hiring them for a standard repair, or especially an EV charger or home battery installation, should ask directly for recent job references and photos of completed work. They're a reasonable call for EV charging or battery-storage installs given the specific certifications on offer, but with no reviews to check yet, get references before committing to anything larger.
