Quality Insulation is the Nashua, NH branch of TruTeam, a national insulation network, installing spray foam, blown-in, and fiberglass insulation along with gutters, garage doors, fireplace surrounds, and foundation waterproofing and sealing for homeowners and builders across southern New Hampshire and northeastern Massachusetts. The business carries a Better Business Bureau A+ grade, and its review record is unusually large — 198 reviews on Google from 2021 through mid-2026, most of them five stars.
The strongest theme across that record is builders and contractors themselves vouching for the work: one local builder describes the company as consistently precise, efficient, and always on schedule; a general contractor working on a six-unit townhouse calls the crew knowledgeable and dedicated; another contractor, describing himself as holding very high standards for work on his own home, says the insulation and air sealing were done correctly and neatly. Several reviews describe large commercial and multi-unit jobs — a library project, a six-unit townhouse, a building remodel — completed cleanly and on time. One especially specific review describes a 150-year-old farmhouse where an elderly widow had gone without adequate heat for decades until qualifying for the state's Weatherization Program, which sent Quality's crew to finally fix the problem. Pricing and scheduling both come up repeatedly as strengths, with several reviewers specifically calling the quotes competitive and the turnaround fast.
But the record also holds several serious, specific complaints spread across different years and crews. A July 2025 review describes a newly installed garage door coming off its hinges with the glass shattering — twice, exactly a week apart, the second time with the reviewer's 13-year-old son nearby. A January 2025 review describes an insulation job that took five separate visits to finish, including a crew that admitted mid-job it hadn't brought enough material and initially had no plan to return with more. A large-scope 2022 review from a general contractor who spent an estimated $30,000 to $35,000 on foundation waterproofing, insulation, a gas fireplace, and gutters expresses clear dissatisfaction with the results. A March 2024 review separately describes a crew whose work the reviewer felt fell well short of expectations on a big job.
Given the volume and variety of the review base — many different named crews handling everything from residential attics to commercial builds — quality appears to vary somewhat by which team shows up, and the last six months brought six more reviews, all positive. For a routine insulation or weatherization job, the record here is deep and mostly strong; for a large-scope project spanning multiple trades, it's worth confirming crew assignment and getting clear commitments on materials and scheduling up front.
