## The honest read

McNamara Construction & Design is a Holden family-owned contractor focused on substantial additions, remodeling, and design-build work. Recent Google customers describe a two-story addition, deck expansion, and multiple projects with clear communication and timely delivery; older reviews describe hardwood replacement and a university renovation. The Massachusetts registry verifies active HIC 133670 and CSL CS-067598 registrations. BBB gives an A+ grade but says the company is not accredited, while BuildZoom lists a 98 score and up to $1 million insured coverage. This looks suited to an addition or major remodel; confirm current insurance, scope, schedule, and payment milestones before signing.

**Strengths:**
- Large remodels — recent reviews describe additions and full-room renovations
- Clear communication — customers repeatedly mention steady project communication
- Project timing — reviewers cite on-time or ahead-of-schedule completion

**Concerns:**
- Insurance confirmation — BuildZoom coverage should be verified before signing
