Green Way Insulation Inc

An attic that used to swing from 140 degrees in summer to near-freezing in winter now holds steady, just a few degrees off the rest of the house — that's the kind of result Green Way Insulation's customers describe when they talk about its spray foam work. The company runs out of 18 Riverside Ave in Danvers, working attics, basements, garages, and crawl spaces across the North Shore with spray foam, fiberglass, blown-in cellulose, and Roxul mineral wool insulation. Its Massachusetts Home Improvement Contractor license (#196010) is active with the state; BBB records show the business was incorporated in February 2018 under president William Costa, about eight years ago — though Green Way's own site describes its team as carrying over 20 years in the insulation trade, a gap between the two accounts that isn't resolved anywhere in the record. The last six months read clean: seven reviews, all five stars, with Gabriel's name coming up again and again for coordinating jobs and following through once a crew is on site. Beyond the attic story above, one recent review describes them stripping out old insulation and sweeping an attic floor clean in an afternoon, after a free estimate the customer called the best price around. Pull back further and the pattern holds over a longer stretch: 45 reviews since 2021 spread across six sites, a 4.8 average on Google from 38 ratings and 4.3 on Angi from 21, with attic insulation work as the recurring theme throughout. It isn't a spotless record. Older Angi reviews describe a job left unfinished, a missed follow-up visit, and a repair that damaged nearby electrical wiring the crew didn't come back to fix — none of that shows up in anything recent, but it's worth asking directly how a callback or a mistake gets handled before signing anything. Green Way also isn't BBB-accredited, even though BBB gives it an A+ underlying grade; accreditation is a separate, optional step, but it means BBB hasn't vetted the business firsthand. For a spray foam or blown-in insulation job anywhere from Danvers up toward the New Hampshire and Maine border, the recent stretch backs the company up. Ask who's actually running your crew and what the plan is if something needs a second visit — that's the one spot where its longer history shows some cracks.
