Insulate 2 Save is a family-run insulation and weatherization contractor based in Fall River, MA, working on wall, attic, basement, crawlspace and knee-wall insulation, air sealing and ventilation for homeowners across South Coast New England, often through Mass Save and other utility rebate programs. The company says it was founded in 2009 by Roland Langevin, his wife Karen Langevin, and step-son Keith Vieira, with Karen Langevin taking over as CEO/President in 2018 and Roland serving as COO/Vice President.
Customers who hired the company consistently describe thorough, professional work. In a 2025 review, a homeowner with a construction background described the crew removing 30-year-old fiberglass insulation from a tight, unconditioned Cape attic and re-insulating with mineral wool batts and rigid foam on the roof rafters, calling the result a 'first class job' comparable to what's illustrated in Fine Homebuilding. In a 2023 review, a homeowner described insulating a 3,600 sq ft 1908 home through the Mass Save program, saying the work had a 'HUGE impact' on the home's air-tightness and that the crew communicated clearly and left the site clean every day. Other reviews spanning 2022 through mid-2026 repeatedly name crew members Mike, Amber and Nelson as attentive and accommodating, describing on-time, tidy work and, in one case, a job finished in two days rather than the week originally quoted. Google shows a 4.6★ average from 37 ratings, and BBB rates the business A+. BuildZoom's permit history shows 540 projects overall, with 168 pulled in the last three years across towns including Falmouth, Teaticket, Braintree, Taunton and South Easton, averaging around $4,783 per project.
One thing worth confirming directly: the company's Massachusetts home improvement contractor license, held under the name Insulate 2 Save, is registry-verified but currently shows as expired.
For attic, wall or basement insulation and air-sealing work in the South Coast region, Insulate 2 Save's project volume and customer track record are strong — it's worth asking directly about the license status before booking.
