Blouin

What Blouin does

Blouin (legal entity Charles P. Blouin, Inc.) is a family-owned industrial HVAC and sheet metal mechanical contractor founded in 1933 in South Boston, currently headquartered in Seabrook, New Hampshire. The company delivers pre-construction planning, in-house fabrication, logistics and material management, and field installation services for complex institutional HVAC and sheet metal projects across the New England region (Massachusetts, New Hampshire, Maine, Rhode Island). It serves four primary verticals: Healthcare, Biotech/Pharmaceutical, Education, and Commercial/Industrial, with marquee clients including Massachusetts General Hospital, Dartmouth College, Novartis Institute for Biomedical Research, Harvard, MIT, Genzyme, Biogen, and Amgen.

Blouin's technical capability centers on a 35,000 square foot Seabrook fabrication shop supported by certified welding, state-of-the-art CNC machinery, 3D BIM modeling for MEP coordination and clash detection, and modular/prefabricated construction methodologies. A secondary Canton, MA office serves as a design, modeling, and BIM coordination hub. The company operates a proprietary logistics fleet of trucks and trailers for just-in-time delivery from a 20,000 SF warehouse and over 10 acres of staging. The branded Airside Direct delivery method packages BIM, equipment procurement, and field labor into a single direct subcontract to construction managers.

The business model is project-based B2B contracting with custom quote-based pricing tied to scope, complexity, and labor/material requirements, structured as multi-year contracts under direct subcontracting or design-assist arrangements with general contractors, construction managers, and institutional owners. Revenue is generated through sheet metal fabrication and installation services. The company is family-owned with no disclosed external capital, no public listings, and no publicly disclosed financial figures, and currently employs 101-250 people.
