Closed Cell Structures, LLC, also known as Build With Foam, describes itself on its own website as a family-owned and operated business whose mission is to provide "the latest innovations in spray foam technology." On the Better Business Bureau, the company describes its own work as spray foam insulation, air tight ceilings, air leak testing and thermal imaging for residential and commercial clients. In 2012, sprayfoammagazine.com described it as a full service building envelope contracting company serving all of eastern Massachusetts and southern New Hampshire. In 2014, sprayfoammagazine.com reported that Angie's List had awarded it the "Super Service Award" for the second year running. A February 2021 Google review said "You could warm my house with a candle after these guys were done!" and said they "communicated seamlessly with my contractor through the whole project." Its Massachusetts home improvement contractor registration, number 157748, is expired on the state registry. The Better Business Bureau grades the company F.
