8–12 Windows

Factors That Affect Your Window Replacement Cost
Window Style
Double hung windows cost less than casement, awning, or large sliding options. Bay and bow window configurations require custom structural framing support.
Glass Package
Low-E solar coatings, argon gas fill, triple-pane glass, and hurricane-impact ratings add to the per-unit material cost.
Frame Material
Vinyl is highly affordable. Fiberglass, composite, and premium wood-clad frames cost significantly more due to advanced manufacturing methods.
Installation Type
Insert replacement is fast and cost-effective if existing frames are sound. Full-frame replacement is required if existing wood frames have structural rot.

Window Replacement Cost & Calculator FAQs
- How much do replacement windows cost on average?
- Replacement window costs vary by style, frame material, and glass package. In Birmingham AL, vinyl double hung windows typically cost $450–$1,300 per window installed, fiberglass windows $1,250–$2,500, and wood-clad windows $1,500–$3,500. A full-home project of 15–25 windows typically runs $10,000–$25,000. Our calculator gives you a personalized estimate based on your exact selections.
- What's the most cost-effective window frame material?
- Vinyl is the most budget-friendly and popular choice for Alabama homeowners. Vinyl windows require virtually no maintenance, offer excellent energy efficiency, and last 25–40 years. For homeowners wanting maximum durability, fiberglass frames expand and contract at the same rate as glass, creating a superior seal that lasts 40–50 years.
- Are energy efficient windows worth the investment?
- Absolutely. Energy efficient replacement windows with Low-E glass can reduce your heating and cooling bills by 25–30% in Alabama's climate. With average annual energy savings of $200–$400 and a typical resale ROI of 70–80%, they pay for themselves while making your home significantly more comfortable year-round.
- What's the difference between double hung and casement windows?
- Double hung windows have two vertically sliding sashes and tilt inward for easy cleaning — they're the most popular and affordable option. Casement windows are hinged on the side, crank outward, and provide the tightest air seal of any operable window. We recommend double hung for bedrooms and living areas, and casement for kitchens and hard-to-reach locations.
- How accurate is this window cost calculator?
- Our calculator uses current 2025–2026 industry pricing data for materials, labor, and installation in the Birmingham metro area. The ±10% range accounts for variables like window size, structural modifications, and accessibility. For a precise, binding quote, we provide a free in-home consultation where we measure every opening and assess your specific needs.
- How long does a full-home window replacement take?
- Most window replacement projects take 1–3 days depending on the number of windows. Our crews typically install 8–12 windows per day. Bay and bow window installation requires an additional day due to structural support requirements. We'll provide a specific timeline during your free consultation.
- Do you offer financing for window replacement?
- Yes, we provide flexible financing solutions through certified lenders to help fit your window replacement project into your monthly budget. Ask our specialists about current zero-down or low-APR options during your free in-home consultation.
- What warranty comes with replacement windows?
- We provide a 3-year workmanship warranty on all window installations. Our window manufacturers (Wincore, Windsor, and Norandex) offer lifetime frame and glass warranties. We register your manufacturer warranty during the final walkthrough so you're fully covered from day one.
