# Frontier Energy Solutions, Inc

**Trade:** Insulation & Weatherization · **Address:** 139 Queen Anne Rd #6, Harwich, MA 02645 · **Phone:** (774) 237-0410 · **Languages:** English

**Rating: 3.4/5** (low confidence) — from 1 reviews across 3 sources.

## The honest read

Frontier Energy Solutions, Inc. is a Harwich-based home energy contractor that has been in business under Massachusetts registration for 19 years, according to its Better Business Bureau profile, and holds an active, registry-verified Massachusetts Home Improvement Contractor license (#160854). Based at 139 Queen Anne Rd in Harwich, the company specializes in energy audits, insulation, weatherization, solar energy, and windows per its BBB listing.

The one detailed customer account on file describes a strongly positive experience: a homeowner hired Frontier for insulation work that followed an energy audit through the Cape Light Compact/RISE program, praising owner John and his staff as courteous, efficient, reliable, and clean, with clear communication at every step. That account is consistent with a 4.3-star Google average from 6 ratings.

Frontier is not a BBB-accredited business, though BBB lists it with an A+ letter grade. The public review record here is thin -- a single detailed account plus a small Google rating base -- so it's worth asking about current pricing and scheduling directly and confirming licensing before booking.

For a homeowner in Harwich or elsewhere on Cape Cod looking for an insulation and weatherization contractor with a verified license and no red flags on file, Frontier is worth a call.

**Strengths:**
- Insulation work — detailed 5-star Google review naming owner and staff
- Active HIC license — registry-verified Massachusetts Home Improvement Contractor #160854
- BBB A+ grade — 19 years in business per Better Business Bureau

**Concerns:**
- BBB accreditation — Better Business Bureau lists them as not accredited
