There is no Massachusetts masonry license, masons work under Home Improvement Contractor (HIC) registration and insurance. A structural chimney rebuild, fireplace repair, or work affecting the building envelope needs a building permit from the Hudson Building Department, 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. Visible exterior masonry work on older homes near the downtown can draw added review, and footings near the Assabet River may involve the Conservation Commission, so confirm before starting.

Hudson sits in the Metrowest/central Massachusetts band, below Boston metro pricing but above the western part of the state. Chimney repointing or tuckpointing typically runs $1,000-$3,000. Rebuilding a chimney above the roofline runs roughly $2,500-$7,000. Relining a flue is usually $2,500-$6,500 depending on height and liner type. A crown or cap repair runs $300-$1,500. Brick or paver walkway and step repair lands around $1,500-$5,000, and a retaining wall can run $4,000-$15,000 or more depending on height and drainage.

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.
