Sertex Utility Services

What Sertex Utility Services does

Sertex Broadband Solutions (legal entity Sertex LLC) is a New England-based fiber optic outside plant infrastructure services provider founded in 1994 and headquartered at 22 Center Parkway, Plainfield, Connecticut. The company delivers end-to-end fiber broadband services spanning engineering and design, aerial and underground construction, fiber splicing and testing, in-home installation and service activation, and ongoing network operations and maintenance. All crews are trained and certified across the full OSP stack, and Sertex markets its ability to design and build in remote, mountainous, and complex New England terrain as a core competency.

The company serves four primary customer segments: ISPs (municipal ISPs, co-ops, and private ISPs such as DVFiber, BroadbandBI, and OpenCape), municipalities and public agencies pursuing broadband initiatives (including Western Massachusetts Municipal Utilities and Maine's Moose Net Middle Mile Network), electric utilities requiring smart grid fiber backbones, and enterprise customers needing dedicated high-capacity connections. Geographic focus is the New England region, with active projects in Massachusetts, Vermont, Maine, Connecticut, and Rhode Island.

Revenue is generated through project-based professional services contracts awarded via a competitive bid process, with pricing quote-based and not publicly disclosed, typically structured as multi-year engagements. The company distributes through direct enterprise field sales targeting municipalities, public agencies, electric utilities, and ISPs. In 2024, Sertex expanded through the acquisition of Maine-based Trenchworks Inc., adding in-house underground trenching capacity for the Maine market. The company is privately held, has no disclosed parent, and shows no public funding rounds or revenue figures in the available data.
