Green Way Insulation Inc

Green Way Insulation is a Danvers spray-foam and insulation crew run by William Costa (with his son Gabriel handling much of the sales and scheduling) — the company has been operating since 2018, and its Massachusetts home improvement contractor registration is active. The bulk of the record, especially the last year, is strong: reviewers describe attics that used to hit 140°F in summer now sitting a few degrees off the house's temperature, a second floor that got noticeably cooler after an unfinished attic was sprayed, and old insulation stripped, bagged, and hauled out before the new foam went in. Recent reviews (7 in the last six months, none negative) keep pointing to the same things — fast estimates, competitive pricing, and a crew that cleans up well enough that one homeowner said it made a building inspection "extremely easy." The written record, though, also carries real complaints spread across several years rather than one bad stretch. In a 2024 review, a homeowner in a tight attic space said the initial insulation job didn't perform well, an inspector found areas that had to be redone, and the crew damaged electrical wiring and compressed AC airflow lines without fixing either. A 2023 review said a spray technician wasn't skilled enough and needed five passes to approach what the contract promised. Several other reviews, from 2022 through early 2025, describe missed callbacks or no-shows — an estimate appointment with no call, a follow-up fix that was agreed to but never happened, a scheduled start pushed because the crew called out. Its BBB profile shows an A+ underlying rating, though the business isn't BBB-accredited. For straightforward attic or crawlspace insulation, Green Way's recent run points to solid, well-priced work — but given the redo and damage complaints on tighter or more complex jobs, it's worth asking directly how they handle a problem if one turns up, and getting any follow-up commitments in writing.
