J Flannery Contracting Inc describes itself as a Metro Boston residential and commercial construction company providing remodeling, renovation and finish work since 2005. Its stated service area includes Boston, Watertown, Cambridge, Waltham, Belmont and Newton, with a focus on carpentry and home remodeling. Older Thumbtack reviews from 2014 and 2015 consistently praised porch framing, finish carpentry, careful workmanship, communication, schedule flexibility, photo updates and attention to detail. BuildZoom reports 13 projects and describes kitchen, bathroom, basement, whole-home remodeling and additions, while Thumbtack lists broad carpentry and remodeling services and three five-star ratings. Before booking, ask which entity and service address will appear on the contract and confirm the current license details. The sources place the business in Watertown, Dedham and Chestnut Hill, and the written customer accounts are dated rather than recent. This looks suited to homeowners seeking carpentry-led remodeling, additions or finish work. Confirm the project scope, current availability, references for similar recent work and the license information before signing.
