## The honest read

Prime Building Inc is a general contractor working out of the Medway/Milford area, offering general contracting, design-build and construction management across commercial, industrial and residential work. The company's own site says it was founded in 2012, with a team it describes as carrying 20-plus years of trade experience.

BuildZoom's permit data backs up a real, established shop: 28 permitted projects on record, a BuildZoom score in the 95th percentile of Massachusetts contractors, and permit valuations ranging from $15,000 up to roughly $1 million across towns including Boston, Brookline, Somerville, Worcester, Taunton and Topsfield. Owner Mark Judson holds a Massachusetts Construction Supervisor license and a Home Improvement Contractor license that BuildZoom verified active in 2026; a separate 1-&-2-Family Construction Supervisor license on file shows inactive.

The two available Google reviews are both five stars and both point to the same names — Mark, Alex and Joe — with one client saying they've worked with the team over a long stretch and would use them again.

Given the range of project sizes on record, it's worth discussing scope and which team handles a job of your size before signing a contract.

**Strengths:**
- Established track record — 28 permitted MA projects, 95th-percentile BuildZoom score
- Licensed — active Construction Supervisor and Home Improvement Contractor licenses on file
- Repeat relationships — reviewers describe long-standing work with the same team

**Concerns:**
- License history — one construction-supervisor license shown inactive on BuildZoom

**Where sources disagree:**
- Website describes the company as based in Milford, MA, while directory records list its address in Medway, MA
