Advanced Green Insulation

Advanced Green Insulation is the volume outfit of South Shore insulation work — 1,684 Google ratings and still five stars overall, the kind of scale that comes from running multiple crews and trucks at once (reviewers cite specific trucks and teams by number — A35, C24, C76 — rather than one owner doing the work). Based in Rockland, the company says it's been in business 14 years, operates under something it calls the Advanced Group, and works spray foam, fiberglass, blown-in cellulose, and fireproof insulation across Massachusetts and New England, with a Martha's Vineyard branch and a sister fireplace business. Its Massachusetts home improvement contractor registration is active, and the Better Business Bureau has A+-accredited it since December 2022. The reviews describe real jobs, not just a company name. One customer had different areas of the house getting different treatments, with the crew sending photos and video updates while she was traveling; another had a full attic conversion insulated fast in extreme summer heat by a two-person team. A repeat customer says they've used the company multiple times, and on one visit an honest mistake was made and fixed without any pushback. Jobs described range from garage and basement spray foam to a full soundproofing job finished under deadline pressure, to roughly 1,500 sq ft of membrane installed over fiberglass insulation with a crew a homeowner called responsive and patient with her questions. Nearly all of that activity is recent — 368 reviews in the last six months alone, every one of them five stars except for a single four-star. Two things are worth knowing before you book. Several 2026 reviews mention a discount offered for paying up front; most describe it as a good deal, but one customer said the pitch initially made her wonder if it might be a scam, even though she was happy with the crew and the price in the end. And federal labor records show the company paid an $85,216 penalty in 2021 for a wage-and-hour violation under the Fair Labor Standards Act — an employment matter, not a complaint about the insulation work itself, but worth knowing. For spray foam, fiberglass, or blown-in insulation anywhere from Rockland out across Massachusetts and New England, Advanced Green Insulation has the scale and a strong day-to-day record to back it up. Ask exactly what a prepayment discount covers before committing to it, and confirm which crew and truck is assigned to your job.
