It's family-owned, and the state's Supplier Diversity Office lists it as a certified Women Business Enterprise, verified active through 2029. In a 2018 case study about the entrance renovation at Massachusetts's State Transportation Building, the glazing contractor who performed the installation, Frank Greatorex Jr., is quoted describing the balanced-door work as trouble-free, saying the updated entrances 'look much more inviting.' K&G has also worked with revolving-door specialists as subcontractors on other commercial installs, including a 2015 restaurant pedestrian-revolver project. This is a commercial glazing and door contractor working on large buildings and storefronts — offices, transportation hubs, restaurants — rather than a residential home-improvement service. A fit for property managers, architects and general contractors with commercial entrance, storefront or revolving-door needs; not geared toward a typical homeowner project. **Strengths:** - Certified WBE — state-verified active Massachusetts Women Business Enterprise - 2018 State Transportation Building — installer praised for trouble-free entrance work - Long-established family firm — self-reports 40 years in business since 1986 ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - In a 2018 case study, the glazing contractor who performed the installation described the entrance renovation as trouble-free and said the updated entrances look more inviting _(confidence: medium)_ - [news.thomasnet.com](https://news.thomasnet.com/companystory/two-dozen-ellison-custom-balanced-doors-revive-boston-s-state-transportation-building-40020049) — “news.thomasnet.com — “I’ve been working with balanced doors for 28 years now and I always recommend Ellison,” says Frank Greatorex, Jr. of K…” - [ellisonbronze.com](https://www.ellisonbronze.com/projects/state-transportation-building) — “ellisonbronze.com — “I’ve been working with balanced doors for 28 years now and I always recommend Ellison,” says Frank Greatorex, Jr. of K&…” - Certified as a Massachusetts Women Business Enterprise (WBE), verified active through the state registry, expiring 2029 _(confidence: high)_ - [Diversity Certification Registry](https://diversitycertification.mass.gov/BusinessDirectory/BusinessDirectorySearch.aspx) — “Massachusetts Supplier Diversity Office Women Business Enterprise (WBE) certification 20200162 verified active — registry holder of record: …” - Self-reports as family-owned and operated, with 40 years in business since 1986 _(confidence: medium)_ - [Official Website](http://www.kgentrances.com) — “Company history (self-reported): The site says K&G Entrances has been a full service glazing company building first impressions for Boston a…” - [Official Website](http://www.kgentrances.com) — “Ownership (self-reported): Family owned and operated” - [Official Website](http://www.kgentrances.com) — “Stated ownership (self-reported): Family-owned” - [Official Website](http://www.kgentrances.com) — “Self-reported 40 years in business” - Full-service architectural glass and glazing contractor that also services and maintains revolving and commercial swing doors for buildings across New England _(confidence: high)_ - [Official Website](http://www.kgentrances.com) — “K&G Entrances is a Billerica, MA full-service architectural glass and glazing contractor that also services and maintains revolving and comm…” - In 2015, brought in a revolving-door specialist as a subcontractor to install a restaurant's pedestrian revolving door _(confidence: medium)_ - [uniondoors.net](https://uniondoors.net/2015/legal-crossing-revolving-pedestrian-door/) — “uniondoors.net — K & G Entrances brought in Union Doors as a subcontractor to install the restaurant’s Horton manual pedestrian revolver.” - Specializes in Windows / Siding / Gutters _(confidence: high)_ - [news.thomasnet.com](https://news.thomasnet.com/companystory/two-dozen-ellison-custom-balanced-doors-revive-boston-s-state-transportation-building-40020049) — “news.thomasnet.com — “I’ve been working with balanced doors for 28 years now and I always recommend Ellison,” says Frank Greatorex, Jr. of K…” - [Official Website](http://www.kgentrances.com) — “K&G Entrances is a Billerica, MA full-service architectural glass and glazing contractor that also services and maintains revolving and comm…” ## Ownership - **Certified woman-owned** — verified against Massachusetts Supplier Diversity Office (WBE #20200162, verified 2026-08-12).
