Pro Electrical Services, Inc. is a licensed electrical contractor based in Billerica, Massachusetts, run by David Mola and serving Massachusetts since 2012 — about 14 years in business, according to the company's own site. It holds active electrician licenses verified by both the Massachusetts and New Hampshire licensing boards, and is an A+ accredited business with the Better Business Bureau. The company describes its work as residential, commercial, and industrial electrical service covering wiring, lighting, backup power, security, telecom, and automation systems, and states a service area spanning towns including Acton, Andover, Arlington, Bedford, Billerica, Burlington, Chelmsford, and Concord.
The written record is unusually deep and consistently strong: Google shows a 5-star average from 85 ratings, and Thumbtack, Angi, and Houzz each separately show a perfect 5.0 as well. Reviews from 2022 through 2026 repeatedly describe fast turnaround — homeowners report being seen the same day, within 30 minutes to a couple of hours of calling, including one Saturday-morning panel emergency diagnosed and fixed within an hour. Several reviewers specifically call out fair, transparent pricing: flat diagnostic rates with no upcharge for minor extra work, and quotes that held to what was promised. The work described spans EV charger installations, panel and wiring upgrades, generator and backup-power work, lighting and smart-device installs, and larger commercial projects such as a multi-building panel and wiring upgrade at a 300-unit condo complex.
An older Houzz review from 2017 describes similar work — ceiling fans, smart home devices, and general electrical repairs — under the same praise for professionalism and cleanliness, showing this pattern of service has held for years rather than being a recent improvement.
There is nothing negative in the written record on file, and no review in the last six months reports a complaint. For a homeowner deciding whether to hire, the consistent theme across dozens of independent reviewers, spanning several platforms and years, is a licensed, responsive electrician with fair pricing and reliable follow-through on both small residential jobs and larger commercial work.
