G Oconnell Construction

The public trail for G Oconnell Construction is permits, not customer accounts. BuildZoom, the only place the Quincy business turns up, lists it at 78 Winthrop Ave under owner Gerald Oconnell and gives it a BuildZoom score of 91 — the site's own proprietary number, which it says ranks in the top 37% of the 139,240 licensed contractors it tracks in Massachusetts. The two jobs on file are structural rather than cosmetic, and both are old. In May 2015 the company pulled a $26,500 permit in Milton for a shed dormer and roof work; in December 2017 it pulled a $49,000 permit in Quincy to rebuild a two-car garage with a side addition for pool equipment. No customer has reviewed the company on BuildZoom, so there is no homeowner account of how either job went. Licensing needs a direct check. BuildZoom lists an active Massachusetts home improvement contractor registration, #146224, which it says it verified as active in July 2026, and an earlier registration, #113721, which it shows inactive and says the state at one point recorded as cancelled. Those are the directory's own records rather than a state verification, and directory licence entries go stale. The permitted work fits additions and garage or dormer projects. Before hiring, ask for the current HIC registration number and proof of insurance, and for references from jobs since 2017 — the documented trail stops there.
