## The honest read

Kinsella Built is a Brookline-based custom construction and renovation company serving Boston-area homeowners. Its own site says the company is fully licensed and insured and has more than 20 years of experience; directory profiles identify a Brookline address, list veteran-owned status, and name kitchen, bathroom, basement, whole-home remodeling, and additions among its services.

Homeowners describe detailed residential work rather than one narrow repair trade. Reviews from 2022 through 2025 discuss kitchen and bathroom remodels, additions, basement finishing, structural work, flooring, electrical and plumbing coordination, and a three-family modular project in Cambridge. Across the dated reviews, customers repeatedly mention responsive communication, careful workmanship, schedule control, and clear cost discussions. A 2025 review specifically praises a bathroom project for staying on budget, while 2023 reviews describe a seven-month addition and basement project and a major Cambridge build.

The public profiles also show concrete work history: BuildZoom lists 13 projects and recent permits for kitchens, bathrooms, siding, basements, and other residential renovations. The official site highlights custom cabinetry, built-ins, trim, decks, patios, tile, and wood floors. Before booking, confirm the exact scope, current license status, and which team members and subcontractors will be assigned, especially for projects involving structural, electrical, or plumbing work. BuildZoom lists Massachusetts Home Improvement Contractor license #196736 as active as of April 2026, while its EPA dust-sampling license entry is marked inactive.

Kinsella Built looks suited to homeowners planning a coordinated renovation, addition, or custom interior build in the Boston area. Ask for a current written scope, schedule, cost controls, insurance details, and any permits required for the proposed work.

**Strengths:**
- Communication — reviewers repeatedly cite prompt, responsive updates
- Renovation scope — documented kitchen, bath, basement, addition, and whole-home work
- Custom interiors — site and reviews support cabinetry, built-ins, trim, and flooring
- Project coordination — customers describe multi-trade work completed to schedule
- Cost clarity — a 2025 review specifically praises staying on budget

**Concerns:**
- Current licensing — confirm active credentials for the proposed scope
- EPA credential — BuildZoom marks dust-sampling license inactive
- Project assignment — confirm team members and subcontractors before booking

**Where sources disagree:**
- The official site says more than 20 years in business, while directory profiles report 22 years.
- BuildZoom lists Massachusetts Home Improvement Contractor license #196736 active as of April 2026 but marks EPA license #NAT-F210482-1 inactive.
- Angi and HomeAdvisor report 32 ratings each, while BuildZoom reports one review.
