Foundation & Basement Masonry in Strawbery Banke, Portsmouth, NH
Looking for foundation & basement masonry in Strawbery Banke 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 Strawbery Banke in Portsmouth includes homes sitting on fieldstone and block foundations, and road salt and plow damage every winter is what wears this masonry down. That is why our foundation & basement masonry work starts with understanding what your building is made of — brick type, stone, mortar hardness, and drainage — before we price anything. Older Boston homes sit on fieldstone and brick foundations that need attention every few decades. We repoint, parge, and repair cracks so the structure stays dry and stable.

No. Hairline vertical cracks are common and often cosmetic. Stair-step, horizontal, or widening cracks need evaluation, and we will tell you when an engineer should be involved.
