G & O, Inc.

G & O is a four-person electrical shop on King Street in Dorchester, run by president John P. Oliveira Jr. and in business since 2001 — 25 years by the Better Business Bureau's count. One customer has written about the work so far: a May 2026 Google reviewer who called the crew detail oriented and recommended them, part of a 5-star average across two Google ratings. BBB's file on the company carries no complaints, and lists it as not accredited and Not Rated, which BBB puts down to insufficient information. The company also appears on leadsafelist.com's roster of lead safe certified firms — worth knowing if your house predates 1978 and the job means disturbing old paint. For a smaller electrical job in Dorchester or nearby, this is a long-running shop with a short public trail behind it. Ask for two or three recent customer references for work like yours, and confirm the lead safe certification is current if your home is older.
