100% of sentiment-scored reviews read net-positive. Last 6 months: 0 reviews, 0 negative.

## The honest read

Nano Building Corp. is a Waltham remodeling and construction company whose recent customers describe deck, stair, kitchen, bathroom, basement, and roofing work. The company says Luiz Fernando Nano founded it and that it has specialized in kitchens, bathrooms, basements, decks, and expansions since 2014.

The written customer history is consistently positive but dated: Google shows 5 stars from 20 ratings, with reviews from 2018 through September 2025. Homeowners describe finished kitchens and bathrooms, a roof, a multi-level deck, a basement office, a detached-garage loft, and water-damaged-basement rebuilding; several also mention on-time completion, tidy work areas, responsiveness, and help choosing materials.

The company’s own site lists renovation and maintenance, construction projects, roof installation and repair, and consulting, with a Waltham address and a self-reported 10 years in business. Houzz lists 11 projects, three Houzz Awards, and a 5.0 rating from three reviews, but the profile is marked suspended. Confirm the profile’s current status and the exact scope, schedule, and roofing or structural responsibilities before booking.

**Strengths:**
- Remodeling range — kitchens, bathrooms, basements, decks, and lofts recur in reviews
- Project care — customers cite tidy work areas and flexible communication
- Material guidance — homeowners mention help choosing tile, hardware, vanities, and glass

**Concerns:**
- Houzz status — profile is marked suspended; confirm current availability
- Scope confirmation — clarify roofing and structural responsibilities before signing
