New Hampshire Spray Foam Insulation

Three attics in one house, all sealed in a single job — that 2022 write-up is the biggest piece of work anyone has described for New Hampshire Spray Foam Insulation, and the customer said the crew delivered on everything they had promised and left the house far more comfortable. The company works out of Webster Street in Manchester, spraying foam and insulating attics and crawl spaces for homes and commercial buildings, and it also pulls out old insulation; its site says it covers New Hampshire without naming particular towns. What people writing more recently talk about is heat and bills. A homeowner in August 2025 said the house already felt warmer and the energy bills were coming down, and that the crew explained everything clearly as they went. Another August 2025 reviewer described the company taking the job at short notice and finishing inside a reasonable stretch of time. In March 2025, a customer who used them on a kitchen called the work fast, affordable and reliable. One August 2025 customer had them go past the foam: the crew put in an air conditioner and sealed all the way around it so cold air would not escape over the summer, then went back over the insulation at the windows and doors. If you want the whole envelope handled in one visit, ask up front how far beyond the foam they will go. Seven five-star Google ratings run from 2022 to 2025. The fit here is a cold attic or a crawl space rather than a whole-house remodel — ask what R-value they are targeting, which cavities are in the scope, and for a certificate of insurance before the trucks arrive.
