What Window Nation does

Window Nation is a privately-held residential window and door replacement company founded in 2006 and headquartered in Fulton, Maryland. The company sells and professionally installs custom-built replacement windows (vinyl, fiberglass, composite, and wood) in seven primary styles — double hung, sliding, casement, bay, bow, garden, and specialty — plus entry, French, and sliding doors, marketed under 1,500+ style and color combinations sourced from multiple manufacturers including MI Windows and Doors, Milgard, Soft-Lite, Harvey, Vytex, and ProVia. It operates a sales-led go-to-market model combining 36+ retail showrooms with a field sales force that conducts in-home consultations, on-site measurements, and customized proposals, with factory-trained installation crews typically completing projects in a single day and backed by a lifetime warranty.

The business generates revenue from three streams: one-time product sales of windows and doors at unit prices ranging from approximately $550 to over $3,500 per window; bundled professional installation, measurement, and disposal services; and customer financing programs (zero down, deferred payments, zero interest for two years on qualifying purchases). The company self-describes as the nation's largest independent window replacement company, citing 3M+ windows installed over a 20-year operating history. It has pursued an aggressive inorganic growth strategy, acquiring ARMORVUE Window & Door in September 2024 and NewSouth Window Solutions from MITER Brands in September 2025, the latter adding nine markets in Florida and South Carolina plus an impact-resistant product line for hurricane-prone regions. In 2026, the company announced expansion into five additional markets including Michigan, New York, and New Jersey, bringing its showroom footprint to 36 locations across the United States, supported by a 501-1,000 employee base and recognition including USA TODAY 2025 Best Places to Work, BBB accreditation, and the Remodeling Magazine Top 500.

Revenue model

1. Window and Door Product Sales: Window Nation generates revenue primarily through the sale of replacement windows and doors to homeowners. Products include various window styles (double-hung, casement, bay, bow, picture, sliding, awning, hopper, garden) and door options (entry doors, patio doors, storm doors) in materials such as vinyl, fiberglass, composite, and wood. Pricing varies by window type, size, material, and features, with ranges from approximately $550 to over $3,500 per window.
2. Professional Installation Services: Bundle of product sales with professional installation services. Window Nation provides complete in-home measurement, professional installation, and old window removal and disposal as part of their service offering. This creates a bundled revenue stream combining product markup with labor and service fees.
3. Financing Programs: Window Nation offers financing options to customers including zero down payment, zero payments for an initial period, and zero interest for two years on qualifying purchases. Financing facilitates higher-ticket sales by enabling customers to pay over time, and the company may receive referral fees or interest income from financing arrangements.
