Verified record
J Walsh William & Son Inc is a small Canton, Massachusetts general contractor run by William Walsh, with a Better Business Bureau file that puts the company at 15 years in business. The one detailed account available describes a new-home foundation on a tight lot in Newton — the reviewer credits the crew's aluminum-form work with hitting the setback lines exactly and finishing on schedule and on budget. Beyond that there isn't much else written about the company online, and its BBB file carries no rating either way, so it's worth asking for a couple of recent addresses or references before signing on for a bigger project.
Simply the best foundations. His aluminum forms are incredible. Larry Walsh has meticulous attention to detail, is efficient, smart and stays on schedule and budget. Building a large house on a small lot in Newton MA, the foundation couldn't miss by an inch as we were tight to the setbacks, and Larry and his team nailed it. The foundation is perfect.
