GDI Home Services

GDI Home Services works the big end of Milton remodeling: 31 permitted projects on file with BuildZoom, mostly six-figure additions, alterations and whole-room rebuilds, with window, roof and siding replacements alongside them. Keith Pentland owns it, and it operates from 28 Winthrop St in Milton. The written record is thin and old. One review exists, posted in March 2013, and it is a 2-star account of a master-bath remodel that began in October 2012 and wasn't finished until February 2013. That homeowner was careful to separate the trades from the management — the subcontractors, they wrote, were excellent; what frustrated them was the coordination, being left hanging when subs couldn't be lined up, and being asked the same questions about orders over and over. Thirteen years on, that single complaint is the whole written history, which is a reason to ask questions rather than a verdict on how the company runs today. BuildZoom lists an active Massachusetts home improvement contractor registration for the business, number 146950, issued in February 2026 — that is the directory's own entry, not a registry check. It also carries a second Massachusetts HIC number, 128241, which it marks inactive and reports as having been cancelled at some point. If you're planning an addition or a gut remodel in Milton, the permit history says they have done that work repeatedly and at scale. Ask who runs the schedule day to day, how subcontractors get booked, and which registration number is the current one so you can check it against the state yourself.
