Foundation & Basement Masonry in Nashua, NH
Looking for foundation & basement masonry in Nashua, NH? Ultimate Boston Masonry is a licensed, insured, family-owned masonry contractor serving Nashua and the rest of Hillsborough County, NH from our Boston base. Nashua's mill-era brick and granite foundations get restoration-minded repointing from our crews.
Housing in Nashua 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 Nashua: Estimates within 72 hours · Typical range $1,500 – $18,000

Process
How foundation & basement masonry works in Nashua

3. Rebuild and repoint
Joints packed in layers with appropriate mortar, then parged where specified.
4. Water management
We address splash, grading, and drainage so the repair is not undone next spring.

Do I need a permit for foundation & basement masonry in Nashua?
Minor repairs usually don't need a permit, but rebuilds, new structures, and tall retaining walls often do under the New Hampshire building code. We check with the Nashua building department and pull permits when required.

Are you licensed and insured to work in Nashua?
Yes. Ultimate Boston Masonry is licensed, fully insured, and family-owned with 5 years of experience on Greater Boston brick and stone.
Are foundation cracks always serious?
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.
Why is my basement damp after heavy rain?
Usually open mortar joints, splash from gutters, or negative grading at the wall. Masonry repair plus water management fixes most cases.
