Window Nation Quick Overview
Aging single-pane or aluminum-frame windows leak heat in winter, let humidity fog glass in summer, and allow street noise inside. Homeowners replace them with energy-efficient vinyl units to cut bills, boost comfort, and update curb appeal. Window Nation fixes this as the third-largest window replacement company in the US. Brothers Harley and Aaron Magden founded it in 2006 in Fulton, Maryland. The company grew organically to 15 markets, now serves 101 metro areas with 785 employees, and has installed over 3 million windows. They focus on vinyl replacements through a buy-two-get-two-free promotion, custom-made for each opening. Over 45,000 customer reviews average 3.8 out of 5 stars overall. More than 95% of their products carry ENERGY STAR certification. In 2026, they expand into five new markets, including Michigan.
Window Nation Company History and Scale
Window Nation started in 2006 when brothers Harley and Aaron Magden launched a family-owned installer in Maryland. Headquartered at 8110 Maple Lawn Boulevard in Fulton, MD, it expanded without heavy franchising. Previously backed by Cortec Group, AEA Investors acquired it recently. Today, it ranks as the third-largest replacement window company nationwide by volume.
They employ 785 people and operate local teams in 101 metro areas. Growth landed them on the Inc. 5000 list of fastest-growing private companies and keeps them in the top 5% of Qualified Remodeler's Top 500 by revenue. Unlike window manufacturers like Pella or Andersen, Window Nation specializes in full-service installation. They custom-measure every job and partner with factories for production. Customers praise prompt, professional crews and one-day installs. Common issues include poor post-sale support and high-pressure sales.
Window Nation Windows and Styles
Window Nation offers vinyl as its best-selling material, with multiple frame options. Glass packages start with double-pane Low-E coating and upgrade to triple-pane with Low-E, argon gas, or premium krypton (98.8% fill) for top efficiency.
Popular Styles
- Double-hung: Both sashes tilt in for cleaning; most common US style.
- Casement: Crank-out for full ventilation and tight seals.
- Bay and bow: Project outward for extra light and space; bays at angles, bows curved.
- Specialty shapes: Custom triangles, semi-circles, octagons, and odd sizes.
They also handle door replacement. Every window custom-fits your openings, even odd sizes. Certified installers on each crew know local weather. One-day installation covers 8–12 standard windows per two-person team. Bay/bow units take longer.
Over 95% qualify for ENERGY STAR, meeting zone-specific U-factor and SHGC ratings (e.g., Northern Zone: U ≤ 0.27). NFRC labels show U-factor, SHGC, VT, air leakage, and condensation resistance. Homeowners report up to 20% lower energy bills.
Window Nation Pricing and Value
Window Nation sits in the mid price tier. Expect $300–$700 per window installed for mid-tier vinyl double-hungs with Low-E and argon in standard sizes. Budget single-hungs run $150–$400; premium glass or fiberglass hits $700–$1,500+. Their buy-two-get-two-free deal lowers effective cost but draws scam complaints from some.
Breakdown: materials 40–60%, labor 30–50%, permits/disposal 5–10%. Labor varies by region. Compared to big-box DIY kits or low-end flyers, Window Nation charges more for custom sizing, certified crews, and lifetime warranty. Value shines in scale (3 million windows installed) and efficiency savings: DOE estimates $100–$465/year per home replacing single-pane units. Payback takes 7–15 years; most replace for comfort and looks, not just energy.
Federal 25C tax credit covers 30% up to $600/year for ENERGY STAR windows (nonrefundable, via IRS Form 5695, through 2032). Aggregate $1,200 cap includes doors/insulation.
Window Nation Warranties and Certifications
Window Nation provides a lifetime warranty on all parts and materials as long as you own the home. It transfers to the next owner for 5 years. This beats basic manufacturer warranties by covering labor too in many cases.
Products carry ENERGY STAR (95%+ qualified) and NFRC labels for energy ratings. AAMA certification ensures structural strength, water resistance, and forced-entry protection (typically R or LC class for residential). Vinyl frames save nearly 2 trillion BTUs yearly nationwide vs. other materials, per Franklin Associates.
They recycle over 8 million pounds of waste annually via manufacturer programs. BBB rates them A+ (accredited since 2024), though customer score is 3.19/5. Angie's List gives 4.7/5.
Window Nation Service Areas
Window Nation operates in 101 metro areas nationwide from its Maryland HQ. Local teams handle regional needs like hurricane impacts in Florida or cold snaps in the Northeast. In 2026, they enter five new markets, including first sites in Michigan.
Check their website for your zip code. They grew to this footprint organically. Coverage beats regional players but trails some franchise networks. Installs follow local codes, including egress (5.7 sq ft clear opening for bedrooms) and permits (required for most jobs beyond like-for-like swaps).
