John A Williams

Twenty-nine permits filed and not a single review anywhere — John A Williams is a Marblehead builder whose whole public trace is paperwork. He works under his own name out of 21 Leggs Hill Rd, and he is the responsible person on the licence as well as the owner. The permits tell you more about the work than the marketing does. What he actually pulls paper for is exterior and structural repair — stripping and re-roofing, replacing skylights, swapping wood siding for vinyl, cutting out and repointing brick, power-washing and sealing masonry, and finishing basements into offices and bathrooms. The advertised list on his BuildZoom page leads with kitchen and bath remodels and whole-home renovation, which is not what the filings mostly describe. The geography is worth a question too. The page describes 28 years serving Marblehead and the North Shore, but most of the permitted addresses sit south and west of Boston — Brockton, Marshfield, Wareham, Dorchester and South Boston — with Beverly the one North Shore job among them. On credentials, BuildZoom lists a Massachusetts home improvement contractor registration, number 143841, and badges it as verified active as of July 2026. That is the directory's own check rather than a state confirmation, so ask him for the number and run it through the Commonwealth's Consumer Affairs site yourself. For exterior repair work — a roof, siding, masonry pointing, or turning a basement into usable rooms — this is a long-established one-man operation with a real filing history behind it. Because nobody has written publicly about the experience of hiring him, ask for two or three recent local references and confirm which towns he currently travels to.
