JP George & Son

JP George & Son works out of 64 Haywood Street in Greenfield and is hired almost entirely for insulation and weatherization: attic and wall insulation, dense-pack cellulose, air sealing, and the venting and door-seal details that go with them. It is a father-and-son crew, and customers name them — Joe George and his son Joe (Joey) — as the people actually leading the work on site. The company holds Massachusetts Home Improvement Contractor registration #156686, which the state registry lists as active under the company's own name. A large share of the work arrives through Mass Save. One homeowner describes an energy assessment on a Wednesday, a call Thursday, and the crew starting Monday. Others describe multi-day jobs on old houses — a three-day project on a home built in 1900, attic flats and knee walls, basement rim joists, weatherstripped exterior doors, a roof vent placed where the owner wanted it after the crew asked. Across 45 reviews written between 2024 and 2026, the same two themes recur: communication and cleanliness. Reviewers say the crew explained the plan before starting, answered questions as they went, and cleaned up so thoroughly at the end of each day that one wrote you would not have known they had been there. Several report a change they can feel — a large attic and crawl space that warmed up immediately, an ice-damming problem a homeowner now considers addressed, a house another owner calls much more efficient. A few accounts speak to how the company handles money and scheduling. A 2024 customer in Barre was rescheduled several times because of a separate contractor's delays and says the job was held on the books for months without complaint. Another says the company amended the Mass Save price after finishing so it matched what was actually done. A commenter in an r/massachusetts Mass Save thread described the same flexibility on scheduling. Windows sit at the edge of the record: a handful of customers mention whole-house replacement windows that have held up over years, a window clip repaired on request, and door kits installed. If windows rather than insulation are why you are calling, ask how much of that work the company still takes on. BBB also lists plastering as one of its categories, while every job customers describe is insulation, air sealing, ventilation or windows. The described jobs sit in western Massachusetts — Greenfield, Barre and nearby towns — so confirm they travel to you. For a Mass Save insulation or air-sealing job in the Greenfield area, this is a deep, recent and consistent record. Confirm the registration number with the state and get the scope in writing before work starts.
