JEC Service Company, Inc.

What JEC Service Company, Inc. does

JEC Service Company, Inc. is a private, full-service mechanical contractor headquartered at 58 Main St, Bolton, Massachusetts, operating across the Greater Boston market. The company delivers HVAC piping, sheet metal fabrication and installation, electrical services for HVAC and mechanical upgrades, and ongoing service and maintenance to commercial, institutional, industrial, and multi-family customers. Its capabilities are anchored in an in-house fabrication shop, union-affiliated labor through IBEW Local 103, in-house CAD drafting, certified welding, and 24/7 emergency on-call response, allowing the firm to act as a single prime for mechanical scopes rather than a specialty sub.

The company's revenue model blends two streams: project-based construction and renovation work billed on a per-project basis, and recurring preventative maintenance and on-call service contracts with property managers, financial firms, and healthcare operators. Pricing is custom-quoted per scope; no standardized rate card is published. Customer acquisition is sales-led, driven primarily through website inquiry and direct outreach, with a project portfolio used as top-of-funnel social proof.

JEC's client base is unusually enterprise-weighted for its size, including Harvard, Brigham and Women's Hospital, Beth Israel Deaconess, Dana Farber, Biogen, Takeda, Ginkgo Bioworks, Microsoft, Tufts, and Northeastern, alongside property managers such as CBRE and Lundgren. The firm operates in a single geography (Massachusetts), holds multiple state trade licenses (PMU 002232, RC 148406, SM 12782, 13159A), and is led by President Wayne Greenwood with a Donato family operations bench (Marc Donato VP, Paul Donato Director of Operations, Paul T. Donato Project Manager), with roughly 20 named personnel across estimating, project management, foreman, and CAD functions.
