Cornerstone Electrical Solutions Corp

Cornerstone Electrical Solutions Corp is a small Medford electrical contractor — one employee on its Thumbtack profile, two years in business there — run by Davidson Lafontant, whose name is the one customers use in their reviews. The Massachusetts state licence registry lists an active electrician licence, number 9275, held by the company itself, and Thumbtack separately shows a verified Master Electrician licence and a background check passed in April 2024. The work customers describe is residential and varied: a 2026 Google reviewer had the company wire a basement from rough to finish, complete an electrical upgrade, redo kitchen lighting and replace outdoor lighting, and wrote that the crew was "transparent, communicative, and showed up exactly when promised. Reliable work, honest service, and fair prices which are rare to find." Its Thumbtack service list runs from lighting, fans, switches and outlets to panel and generator work. The track record is genuinely positive but still short: four reviews across Google and Thumbtack between 2024 and 2026, all five stars, two of them in the past six months. Earlier Thumbtack customers called him honest and efficient and said he was a pleasure to work with. With a record this small, the sensible next step is the ordinary one: ask for two or three references from jobs like yours, confirm which licence number will be pulling the permit, and get the scope in writing. For a homeowner wanting an owner-run electrician who answers the phone and does the work himself, the early signals are good; there just is not much history behind them yet.
