Quietstar Industries LLC

Complete silence in a 19th-century co-op: that is what a March 2023 Google reviewer said they got after Quietstar Industries' crew member John installed an acoustic entrance door in their apartment, enough that the neighbors could no longer complain about the reviewer's loud music. The Randolph company describes itself as a noise-control specialist for industrial and architectural applications, offering noise-reducing rooms, doors, windows, barriers, enclosures, operable and glass wall partitions and air moving attenuators. The Procore Construction Network shows 54 of its projects and lists acoustic treatment, doors and frames, and door and window hardware among its services. It has four Google ratings, all 5 stars.
