Estimates window replacement cost per unit based on window size and style (single-hung, double-hung, casement, sliding, picture, bay/bow), frame material — vinyl ($250–$600), wood ($400–$900), fiberglass ($500–$1,000), or aluminum-clad ($450–$800) — glass package (double-pane Low-E at $0 upcharge, triple-pane at $50–$100/unit, argon vs. krypton gas fill), and installation type: retrofit insert into existing frame ($150–$300 labor) vs. full-frame replacement with new flashing and interior trim ($300–$600 labor per unit).

Data Sources:

• RSMeans 2024 Residential Cost Data
• Energy Star window efficiency data and Most Efficient product list
• HomeGuide window replacement surveys (35,000+ projects)
• National Fenestration Rating Council (NFRC) U-factor and SHGC performance labels
• Remodeling Magazine Cost vs. Value Report 2024 for vinyl and wood window ROI

Key Assumptions:

• Retrofit (insert) installation into existing frames is the baseline
• Low-E double-pane glass is the standard specification
• Existing wood frames are structurally sound with no rot — frame rot repair adds $100–$300 per window
• Lead-safe work practices are followed for pre-1978 homes per EPA RRP Rule (may add $50–$100 per window in containment costs)
