B. Alpha Construction LLC

Customers of B. Alpha Construction don't write about a company — they write about Yamil, Mark and Joel by name. Across four years of Google reviews the same partners keep turning up: coming back to re-measure an estimate in person, calling ahead when they were running a few minutes late, explaining what the crew was doing while the foam went in. The Chicopee company says it was founded in 2021 by three partners out of the insulation worker co-op Energia, with a combined 40-plus years in building performance, and that it is minority-owned and operated. The work is insulation and little else: two-part spray foam in open-cell, closed-cell and hybrid, plus blown cellulose and injection insulation, in houses, multi-family and new construction as well as commercial and municipal buildings across Western Massachusetts. It also handles the Mass Save and tax-credit rebate paperwork that can cover 60 to 100 percent of a retrofit. Its Massachusetts home improvement contractor registration is active. The written history runs deep for a five-year-old firm: a 4.8★ Google average across 24 ratings, a 5.0 across three Angi reviews, and nothing negative in the last six months. A July 2026 customer described a crew that was polite, explained the whole process and cleaned up well. A June 2026 homeowner met Mark about spray foam and came away recommending him. Reaching back, an October 2024 customer working through Mass Save said the crew found a problem inside a wall mid-job, flagged it immediately and photographed it; an August 2025 reviewer said the house was left cleaner than the crew found it, on a brutally hot day. Commercial work shows up too — a December 2022 reviewer had 20,000 square feet insulated at a facility in Lee with the crew working around the plant's operations, and a January 2025 customer had insulation supplied and installed for a mid-rise. Two dated accounts show how they handle trouble. In August 2023, a job stalled when the spray rig's gun failed and a second crew came out the next day to finish. In October 2025, another equipment problem came up and the customer's main contact adapted, taping off the whole house to get ready. Reviewers in 2022 and 2023 kept making the same point about crawl spaces and cramped, awkward spots: the crew got in and got it done. Two things to know before calling. The Better Business Bureau grades the company A-, citing the length of time it has been operating — consistent with its own 2021 founding. And equipment going down mid-job has come up twice in reviews, so it is fair to ask what the backup plan is if a rig fails on your house. For a crawl space, a duplex, an addition or a commercial retrofit in Western Massachusetts, this is a specialist rather than a general contractor branching out. Ask who your day-to-day contact will be, have them walk you through the Mass Save rebate math before you sign, and get the schedule in writing.
