Knights Masonry & Foundation Waterproofing

There is no Massachusetts masonry license, masons work under Home Improvement Contractor (HIC) registration and insurance. A structural chimney rebuild, fireplace repair, or any work affecting the building envelope needs a building permit from the City of Boston Inspectional Services Department (ISD), and chimney lining must meet the state fire code (527 CMR) for clearances and listed liners. CSIA chimney-sweep certification is voluntary but worth asking for. In Back Bay, Beacon Hill, and Bay Village historic districts, any visible exterior masonry change, a rebuilt chimney top or repointing color, draws Boston Landmarks Commission review.

Boston masonry runs high for the state because of building density, parking and staging constraints, scaffolding on tall row houses, and union labor. Chimney repointing or tuckpointing typically runs $1,500-$3,500, more when a lime-mortar match and roof-level access are involved. Rebuilding a chimney above the roofline runs roughly $3,000-$8,000 and up on a four-story triple-decker. Relining a flue is usually $2,500-$7,000 depending on height and liner type. A crown or cap repair runs $400-$1,500. Brick step and walkway repair lands around $2,000-$6,000, with historic-brick matching pushing the upper end.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential masonry & chimney work; ask for the registration number and check it before paying a deposit.
