Summit Insulation Co

Summit Insulation Co is a Harwich-based insulation and weatherization contractor run by William (Bill) Hadfield, who holds Massachusetts Home Improvement Contractor license #191068 in the company's own name — verified active with the state registry. The Better Business Bureau lists the business as operating since 1995 with about 9 employees, though its BBB file (opened in 2018) carries no accreditation and no rating for lack of sufficient information. The one retrievable customer account, a 2022 Google review, describes Hadfield responding quickly with foam-versus-fiberglass insulation pricing — the reviewer credited him with a fast, direct reply to a pricing request rather than describing a finished installation. Because the record here is thin — a single review and no completed-job accounts — homeowners should ask for references or examples of recent insulation work before booking, and confirm current licensing and insurance directly.
