Verified record
John W. Thompson holds an active Massachusetts electrician license (#15355), based in Chelsea. Records tie him to JTech Electric Inc., a Chelsea electrical contracting company Better Business Bureau lists him as president of, in business 32 years and graded A+ by BBB; BBB describes its work as new wiring installations, old wiring repairs, service upgrades, fire warning systems installations, standby generator systems, and power distribution and telephone/CATV interior wiring. BuildZoom separately lists the same license number and shows one project logged under his name. Before hiring, confirm the scope of the job, current insurance, and which entity — the licensed individual or JTech Electric Inc. — will be doing the work, since the Better Business Bureau listing for JTech Electric gives a different Chelsea address than the one on file here.
