USA Insulation of SNH, based in Litchfield, NH, says it has 41 years of experience installing blown-in, batt and spray-foam insulation as well as soundproofing for southern New Hampshire homes. Its written review history on HomeAdvisor runs from 2021 to 2022 — 25 reviews averaging 4.6 stars, most describing crews as professional, courteous and thorough. In a 2021 review, a homeowner detailed a blown-in attic insulation project brought up to R49 with foam-board sealing around ductwork and light fixtures, calling the crew's work clean and complete; another 2021 review described a sunroom insulated with plant-based foam. A few things are worth raising before booking: in a 2022 review, a customer said a soundproofing installation produced no noticeable noise reduction and follow-up requests went unresolved; in a 2021 review, a homeowner said removed siding wasn't properly rehung after an insulation job; and the Better Business Bureau lists two complaints against the company in the last three years, including a 2025 dispute over an insulation job the customer said caused property damage that the business's response didn't fully resolve. For a straightforward attic or wall insulation job the record is largely strong, but given the BBB complaint and the siding issue, ask upfront how the crew protects existing finishes and wiring, and what happens if results fall short.
Professional service at a good price.
I had reached out to this company for soundproofing between two units and was advised their product would help eliminate sound between the two. It was advised it would not be 100% soundproof because of the attic and the basement, but indicated it would be a significant reduction in noise. Shortly after a new tenant had moved in, there was no difference in soundproofing. When I had reached out directly to the company with my concerns, they said they had a system in play and would connect me with the manager. I had to follow back up several times before I had finally received a response indicating there was no guarantee of soundproofing and nothing could be done. In short, this was a complete WASTE of money.
Very professional. On time. Answered all questions. Cleaned up very thoroughly.

Attic Insulation Project - instead of spray foam, elected to go with added blown-in insulation to R49, adding foam board around attic opening and sealing (openings such as around duct work, wiring. light fixtures in ceiling. etc.). The team did everything professionally (as per their quote) and courteously. They cleaned up and were very thorough. Great job!
