It holds 5 stars from 107 Google ratings and an A+ from the Better Business Bureau. A recent customer laid out an attic job step by step: the old insulation came out to expose cracks and wire penetrations for air sealing with expanding foam, 6mm poly sheets went between the joists as a vapor barrier, and 17 inches of cellulose was blown in to reach R-60. A recent customer says Bennett and a co-worker installed R21 mineral wool on the basement rim joists, removed the old fiberglass and HEPA vacuumed the area. A recent customer with aluminum siding says Bennett's crew blew cellulose into the whole house from the exterior in two days with no damage to the siding, after another company said it does not work on houses with aluminum siding. A recent customer says the crew brought a 100-year-old house's small attic up to R49, working in a cramped, hot space. The office side matters here too. A recent customer says office manager Jen coordinated the work and the rebate application process. In a 2026 review, a customer said Nealon handled the paperwork for Eversource's rebate program on an attic job that put in 10 inches of new cellulose with the goal of R-49. In a 2025 review, a customer with an 1880 house said the team, led by Chris, did a full blown-in cellulose install by reaching the framing from the siding, and that the third floor afterward held its temperature for hours after the AC came on. A recent customer says there were two issues with the ceiling at the end of an attic job, and that Nealon got someone out right away to fix them. Connecticut lists its home improvement contractor registration, HIC.0699578, as active, held by Nealon Insulation. **Strengths:** - An R-60 attic job — a recent customer described air sealing and blown cellulose - Aluminum siding work — a recent customer says there was no siding damage - Rebate paperwork — a recent customer says Jen coordinated the rebate application - A cramped attic — a recent customer says the crew reached R49 **Concerns:** - Two ceiling issues — a recent customer says both were fixed right away ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Air sealing, a poly vapor barrier and 17 inches of blown cellulose to reach R-60 in an attic _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2pOZmNEUTBaRWhxYUdGSU5qQm1iakY1YTFSMU5tYxAB!2m1!1s0x0:0x13fae8db9ac83ad6!3m1!1s2@1:CAIQACodChtycF9oOjNfcDQ0ZEhqaGFINjBmbjF5a1R1Nmc%7C%7C?hl=en-US) — “5★ Summary – Nealon Insulation did an exemplary job at reinsulating our home’s attic; their work met or exceeded all my expectations.
