# Summit Insulation Co **Trade:** Insulation & Weatherization · **Address:** 166 Queen Anne Rd, Harwich, MA 02645 · **Phone:** (508) 430-8144 · **Languages:** English **Rating: 3.1/5** (low confidence) — from 1 reviews across 5 sources. ## The honest read 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. **Strengths:** - Responsive to inquiries — reviewer praised owner's fast pricing reply - Registry-verified license — HIC 191068 active under company's own name **Concerns:** - Limited review history — only one customer account currently on file - No completed-job account — sole review covers a pricing inquiry, not finished work **Where sources disagree:** - BBB categorizes the business under Plastering Contractors, but the company's own name, license type, and BuildZoom category all point to insulation work — likely a BBB miscategorization rather than a different trade. - BuildZoom lists phone (508) 237-1259 for this business while BBB lists (508) 430-8144 for the same PO Box 1337, Harwich address — two different numbers, unclear which is current. ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Holds Massachusetts HIC license #191068, registry-verified active under the company's own name, Summit Insulation Co., Inc. _(confidence: high)_ - [State License Registry](https://contractorhub.mass.gov/s/hic-contractor-search) — “MA hic license 191068 registry-verified active — registry holder of record: SUMMIT INSULATION CO., INC.” - A 2022 Google reviewer praised owner Bill Hadfield for responding quickly with foam-vs-fiberglass insulation pricing. _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChZDSUhNMG9nS0VJQ0FnSUR1bU51WmRREAE!2m1!1s0x0:0x438740d880cecd3e!3m1!1s2@1:CIHM0ogKEICAgIDumNuZdQ%7C%7C?hl=en) — “5★ I was looking for pricing for foam insulation versus fiberglass.
