Verified record
J & M Brown Co Inc is a Dedham electrical contractor whose own site describes electrical construction alongside low-voltage infrastructure, fire alarm, security systems, and service and maintenance. Procore lists the company as a general contractor specializing in electrical work and serving Dedham and Boston. The written customer record is thin but positive: a 2019 Google reviewer called it the best electrical contracting company in the greater Boston area and highlighted security, audiovisual, and communications under one roof. Google currently lists a 4.6-star average from 10 ratings. Its work is a fit for commercial or infrastructure projects that need coordinated electrical and low-voltage systems. Before booking, confirm the exact scope and current availability; the only written review is dated 2019, so it should not be read as a current project account.
The best electrical contracting company in the greater Boston area, with one stop shopping for security, audio visual, and communications!
