## The honest read

Golden Key Advisors is Shari and Sheldon's general contracting and carpentry outfit in Boston, working out of a Centre Street office since the LLC was formed in 2023. Reviewers name the two of them by name in almost every account, and the jobs described go well past typical construction work — everything from building a backyard gazebo to mounting a television.

The reviews describe consistent, hands-on service across a range of jobs. In a 2024 review, a homeowner said the team poured concrete footings and built a 12-by-20-foot gazebo over two days. In a 2025 review, a customer credited Sheldon with a neat, professional gazebo installation from start to finish, and another 2025 review described the two of them helping a first-time homeowner choose appliances and light fixtures before installing everything smoothly. In a 2023 review, a customer said Shari and Sheldon painted their condo and that they'd hire them again "at a drop of a hat."

They also take on smaller household requests. In a January 2026 review, a customer described them removing old forced-air vents from a condo and sealing the walls and floors, and other reviews mention them assembling a swingset and installing a large flat-screen TV. Every one of the 17 reviews on Google, dated 2023 through early 2026, is five stars.

The business is certified as both a Minority Business Enterprise and a Women Business Enterprise by the Massachusetts Supplier Diversity Office, verified active through October 2027. The Better Business Bureau grades it A+, though it isn't BBB-accredited and shows no complaints on file.

One thing worth confirming directly: Golden Key's own website states it holds a Massachusetts Home Improvement Contractor registration, but that number hasn't been checked against the state registry. BuildZoom separately lists two HIC license numbers for the business, and the more recent one showed an October 2025 expiration date at BuildZoom's last check — worth asking whether it's since been renewed.

For a backyard structure, small renovation, or an odd install-and-assemble job around the house, Golden Key's history of five-star, repeat-customer reviews makes a strong case — just confirm the current license status before signing anything.

**Strengths:**
- Custom outdoor structures — reviewers describe gazebos, decks, and porches built to spec
- Wide small-job range — TV mounts, appliance installs, and furniture assembly all covered
- Repeat customers — several reviewers say they've hired Shari and Sheldon more than once

**Concerns:**
- License status unclear — the website's registration number isn't checked against the registry
- BuildZoom license expiring — its more recent number showed an October 2025 expiration

**Where sources disagree:**
- The business's website states a Massachusetts Home Improvement Contractor registration that has not been verified against the state registry, while BuildZoom separately lists two different HIC license numbers, one showing an October 2025 expiration at its last check.
