New Hampshire Spray Foam Insulation

New Hampshire Spray Foam Insulation works out of Manchester, offering residential and commercial spray foam, attic insulation, crawl space insulation and insulation removal, according to the company's own site. Reviewers keep describing the same thing: fast, professional service, often on short notice. Seven Google reviews from 2022 through 2025 are all five stars, with real specifics behind them. In a 2025 review, a customer described the crew insulating around a newly installed air conditioner so no cold air escaped during the summer, and reinforcing the insulation around the windows and doors at a discount. Another 2025 review credited the work with a warmer home and lower energy bills, and said the crew explained the process clearly along the way. Further back, a 2022 review described all three attics in a house being sealed, calling the crew professional and adding a plan to call them again for future work. The company describes itself as "licensed, bonded and insured" on its own site, though it doesn't list a license number — New Hampshire doesn't require a state license for insulation work, so there's no registry to check that claim against. For attic, crawl space, or spray-foam sealing work around Manchester, this is a crew with a small but consistently positive track record; it's worth asking what proof of bonding and insurance they can show before booking, since that part rests on their own word.
