A family business. A craftsman's standard.
Sergio's Insulation was built on a simple idea: treat every house like it's the one your own family lives in. That's it. That's the playbook.
The story
Sergio came up in the trades the same way most good contractors do — with a tape measure, a question, and a willingness to do the job twice if it wasn't right the first time. After more than a decade applying spray foam and batt insulation for other companies, he decided to start his own shop.
The promise was simple: honest quotes, clean job sites, trained applicators, and follow-through. Today, Sergio's Insulation serves homes and contractors across Massachusetts and northern Rhode Island — from single-attic top-offs to whole-house new construction.
We're a family business in the truest sense. That means when you call 774-204-5125, you talk to someone who actually cares about what gets installed in your walls.
Jesus Christ Loves You.


Faith & family
Built on values that show up in the way we treat customers, crews and homes.
Trade-first
We're applicators, not salesmen. Every quote comes from someone who's done the work.

You can drive past our shop. You can call our office. We're not going anywhere.
Done right. The first time.
We treat every house — from a 600 sq ft cape to a 6,000 sq ft new build — like it's our own. That means honest advice, the right product for the cavity, and a finished job you can't see — but you'll feel for decades.
