Eco Insulators, LLC

Almost every review of Eco Insulators is really a review of one person: Chris Welch, the Franklin owner who comes out to quote the job and is often on it. Forty-two Google ratings, every one of them five stars, with five-star handfuls on Angi and HomeAdvisor behind them, and the same pattern repeating across four years — he lays out the options, prices them, then does what he said on the day he said. The work is insulation and the sealing that goes with it: blown-in fiberglass and cellulose in attics and basements, closed-cell foam in basements, walls, a porch, a new addition. A homeowner writing in March 2026 had fiberglass and cellulose put into the attic and basement and felt the difference in comfort straight away; another this April described a candid assessment of what the house actually needed rather than a bigger sale. Work areas get swept at the end of each day — that detail shows up again and again — and several customers noted the final bill matched the quote. The history runs deep for a small shop: 45 reviews from 2022 through this year across seven sources, none of them negative, and a BBB file that has been accredited since December 2022 with an A+ and no complaints. A general contractor writing in October 2025 said he uses them as a sub on his own remodeling and building jobs. And in a 2023 review, a homeowner whose attic pipe burst in a cold snap said other contractors pushed the rebuild out by weeks while Chris came straight out and quoted it. The thing to settle before signing: the state registry shows this company's Massachusetts home improvement contractor registration, number 204573, as expired. The BBB profile lists that same number along with a construction supervisor licence, CSSL-106225, showing a February 2027 expiration — that second one is the bureau's listing, not something confirmed against the state. Registration is what puts a homeowner in reach of the state's dispute process if a job goes sideways, so ask to see a current one before work starts, particularly since reviewers describe them doing windows, an entry door, walls and bathroom work as well as insulation. One more note, from a 2023 basement foam job: that customer said theirs was not the cheapest bid and thought the warmth was worth it. If budget is tight, price the alternatives. For an attic or basement that never holds heat, this is a small, closely-run crew with an unusually clean four-year history — get the registration sorted, then let them at it.
