What Mathews Brothers does
Mathews Brothers Company is a family-owned window and door manufacturer headquartered in Belfast, Maine, operating as America's oldest window manufacturer since its founding in 1854. The company produces two principal product families: the premium Sanford Hills Collection, featuring historically accurate profiles, extensive customization options, and industry-leading PG50 Performance Grade ratings, and the Spencer Walcott Collection, a value-tier offering of energy-efficient vinyl windows and doors targeted at everyday residential projects. In 2026 the company introduced VIG (Vacuum Insulated Glass) technology, a vacuum-sealed two-pane glass system claimed to outperform tri-pane alternatives on u-values while weighing less. Core manufacturing technology includes Low-E insulating glass with argon gas fill, Duralite warm-edge spacers, and fusion-welded frame construction across two production facilities in Belfast and Hermon, Maine.
The company operates a manufacturer-only go-to-market model, selling exclusively through a network of 180+ authorized dealers across seven Northeast states (Maine, Massachusetts, New Hampshire, New York, Vermont, Connecticut, and Pennsylvania). End customers include homeowners, builders, contractors, and architects serving both residential replacement/renovation and new construction use cases, with named channel partners including Hammond Lumber, RK Miles, Erie Materials, Belletetes, Cape Cod Lumber, and Brill Lumber. The Hawthorne family — currently represented by President Scott Hawthorne, VP of Operations Kyle Hawthorne, and Executive Vice President Alex Hawthorne — has led ownership since 1986, with no disclosed external investors, private equity, or parent company. The business transitioned from a retail-plus-manufacturing model to a pure manufacturing/distribution model in 2008.
Revenue mechanics are tied to wholesale hardware sales of windows and doors through dealer partners; consumer pricing is not publicly disclosed and is managed at the dealer level. Marketing combines TV advertising, organic social (Facebook, YouTube), a digital visualizer tool, technical documentation (REVIT and CAD models), and dealer-led bottom-of-funnel conversion. Recognition includes Best Places to Work in Maine (2025, 2026), a 2011 National Glass Association Crystal Achievement Award, and a 2000 Window & Door magazine national industry award for small business marketing.

Mathews Brothers competitors and assessment
Company assessmentBroad incumbents
- Alside: Associated Materials vinyl window and door brand focused on remodeling and replacement via dealer and contractor channels. Competes with the Spencer Walcott value line in dealer-served U.S. markets.
- Andersen Windows & Doors: Largest U.S. window and door manufacturer (100-Series, 400-Series, A-Series) with national dealer and big-box presence. Overlaps with both Mathews Brothers product families but at vastly greater scale and broader category coverage.
- Pella Corporation: Major national window and door manufacturer with multiple product tiers (Pella Reserve, Pella Impervia, Pella 250/350/350 Lifestyle) and a strong dealer-network model analogous to Mathews Brothers' channel strategy.
- JELD-WEN: Public global manufacturer of windows, doors, and millwork products across multiple price tiers. Direct competitor in the window and door categories with national distribution, supplying builders and dealers across the U.S.
Direct peers
- Harvey Building Products: Northeast U.S. window and door manufacturer and distributor with a similar regional dealer-based go-to-market. Direct competitor in replacement and new construction markets across New England and Mid-Atlantic where Mathews Brothers operates.
- Marvin Windows and Doors: Family-owned premium window and door manufacturer (Warroad, MN) with comparable high-end and historically accurate product lines (Marvin Signature, Integrity). Direct premium-segment competitor serving similar architects, homeowners, and custom builders.

- Integrity Windows and Doors: Marvin's Ultrex-fiberglass-based window and door line targeting premium replacement and new construction. Comparable in positioning to the Sanford Hills premium tier with a focus on durability and energy performance.
- Window World: Largest U.S. direct-to-consumer window replacement franchise. Tangentially comparable in replacement-customer focus, though operating a fundamentally different (company-owned store, vertical sales) business model than Mathews Brothers.
