Indoor Fireplace & Firebox Repair in South Boston, Boston, MA

Looking for indoor fireplace & firebox repair in South Boston in Boston, MA? Ultimate Boston Masonry is a licensed, insured, family-owned masonry contractor serving Boston and the rest of Suffolk County from our Boston base. From Back Bay brownstones to triple-deckers in Dorchester, Boston masonry is old, soft-brick work that needs the right mortar and a careful hand.

Housing in South Boston in Boston includes tight lots with shared driveways and close neighbors, and New England's 60–100 freeze-thaw cycles a winter is what wears this masonry down. That is why our indoor fireplace & firebox repair work starts with understanding what your building is made of — brick type, stone, mortar hardness, and drainage — before we price anything. Cracked firebrick, loose hearths, and eroded smoke chambers are fire hazards. We rebuild fireboxes with firebrick and refractory mortar, reset hearths, and restore brick and stone surrounds inside the home.

Response time in Boston: Same-day estimates, most weeks · Typical range $500 – $6,000
