Looking for chimney repair & rebuilds 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 a mix of Victorian, colonial, and mid-century homes, and spring snowmelt that saturates masonry and soil is what wears this masonry down. That is why our chimney repair & rebuilds work starts with understanding what your building is made of — brick type, stone, mortar hardness, and drainage — before we price anything. New England chimneys take the worst of the weather. We repair crowns, rebuild spalled brickwork above the roofline, reset crooked caps, and seal the flashing so water stops finding its way inside.

Response time in Cambridge: Estimates within 24 hours · Typical range $650 – $6,500

Are you licensed and insured to work in Cambridge?

Yes. Ultimate Boston Masonry is licensed, fully insured, and family-owned with 5 years of experience on Greater Boston brick and stone.

How do I know if my chimney needs a rebuild instead of a repair?

If mortar joints are soft more than an inch deep, bricks are flaking or shifting, or the stack leans, a rebuild above the roofline is usually the lasting fix. Anything shallower is normally a repoint and crown repair.

Will you match my existing brick?

Yes. We source brick by size, color, and texture, and tint mortar to match aged joints so the repair blends with the original stack.
