Alpha Weatherproofing Corporation is a Quincy-based building-envelope restoration contractor that, by its own description, has spent nearly 45 years working with engineers, architects, building owners and property managers across Greater Boston and New England — facade inspection, concrete and masonry restoration, waterproofing, roofing, and structural repair, with the company crediting its founding to 1981 under Paul Capobianco and Jim Saulnier. Beyond that self-description, there isn't much of a customer record to go on. Google shows a 3-star average from only two ratings, and the one written review on file — from 2023 — described unsecured material falling off a company truck onto the reviewer's car, calling the incident unsafe and unprofessional. Two things are worth checking before hiring. The company's Massachusetts home improvement contractor registration is verified expired with the state, and its Better Business Bureau profile carries a B- grade — downgraded after the company did not respond to a complaint filed against it — with no BBB accreditation. Given how thin the public record is, and that Alpha describes its client base as largely commercial and institutional rather than residential, a homeowner considering them for a house project would do well to confirm current licensing directly and ask for recent, comparable residential references before signing anything.
Company truck didn't strap down material and had all of it cover my car making me almost crash very unsafe and unprofessional.
