Damon Insulation Co is a mechanical insulation contractor based in Bow, New Hampshire, with a second office in Bangor, Maine, working strictly commercial and industrial jobs — pipe insulation, high-temperature removable insulation blankets on steam turbines, and design-build insulation projects for clients that range from convenience stores to paper mills, including pharmaceutical facilities. Procore Construction Network's directory tracks 44 projects under the company's name, averaging $7.37 million each — a scale that points to sustained work on sizable industrial and commercial builds rather than one-off jobs. The written record here is thin and dated: the one review on file, from a 2020 Google rating, is a brief, general note about a mutual working relationship rather than a description of specific work, so there isn't much beyond the company's own account to weigh. Anyone considering them for a commercial or industrial mechanical insulation project should ask for current references and recent project examples directly, since the public review trail doesn't offer much to check against.
