Indoor Fireplace & Firebox Repair in South End, Portsmouth, NH
Looking for indoor fireplace & firebox repair in South End in Portsmouth, NH? Ultimate Boston Masonry is a licensed, insured, family-owned masonry contractor serving Portsmouth and the rest of Rockingham County, NH from our Boston base. Portsmouth's historic brick downtown requires soft lime mortar and traditional joint profiles.
Housing in South End in Portsmouth includes homes sitting on fieldstone and block foundations, 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.
