What Brosco does
BROSCO, operating as a Boise Cascade location since 2023, is a wholesale distributor of doors, windows, and millwork products serving the Northeastern United States. Founded in 1890 as Brockway & Smith in Lynn, Massachusetts, the company has operated continuously for over 130 years through multiple name changes and is currently the largest millwork distributor in the Northeast, with 550,000+ square feet of warehouse, shop, and office space across three facilities in Andover, Hatfield, and Portland. Its distribution footprint covers New England, Eastern New York, New York City, Long Island, and Northern New Jersey, exclusively through independent lumberyards, home centers, and retailers — the company does not sell direct to consumers.
The company operates eleven product categories including exterior and interior doors, windows, moulding, stair parts, railing systems, columns, commercial products, composite millwork, specialty windows, and storm/screen doors. BROSCO runs in-house fabrication shops at its Hatfield and Portland distribution centers producing custom 'Built by BROSCO' door and window units with NFRC energy ratings, NAMI structural certifications, Warnock-Hersey fire-door labeling, and Energy Star compliance. Its proprietary BROSCO Flat Shaker Fiberglass Doors line launched in 2025, while supplier-brand partnerships with ODL, Simpson, LARSON, Eclisse, INTEX, and Crown Heritage supply additional product breadth.
Revenue is generated through wholesale hardware sales to the dealer network and professional services revenue from custom unit assembly. Pricing is quote-based and catalog-driven at the dealer level, with dealers setting end-consumer pricing. The BROSCO XPress online portal supports dealer ordering, quoting, and invoicing. Distribution is exclusively indirect-to-dealer, with no direct-to-consumer sales channel. The company's strategic supplier relationships (notably the ODL primary-supplier agreement rolling out in 2026) and brand positioning around Northeast-specific climate-engineered products form the core of its value proposition to building professionals and homeowners.
