Foundation & Basement Masonry in Porter Square, Cambridge, MA
Looking for foundation & basement masonry in Porter Square in Cambridge, MA? Ultimate Boston Masonry is a licensed, insured, family-owned masonry contractor serving Cambridge and the rest of Middlesex County from our Boston base. Cambridge is dense with 19th-century brick that was built with lime mortar. We match historic joints instead of forcing hard modern mixes onto old walls.
Housing in Porter Square in Cambridge includes tight lots with shared driveways and close neighbors, and spring snowmelt that saturates masonry and soil 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.
Response time in Cambridge: Estimates within 24 hours · Typical range $1,500 – $18,000

Joints packed in layers with appropriate mortar, then parged where specified.
