Window Replacement Cost by Material
Window cost is driven by frame material, glass type (single, double, triple-pane), and window style (double-hung, casement, picture). Here are 2026 installed costs per window for standard sizes:
| Frame Material | Double-Hung (installed) | Notes |
|---|---|---|
| Vinyl | $450–$700 | Low maintenance, good value, limited colors |
| Wood | $800–$1,400 | Classic look, requires painting, premium price |
| Fiberglass | $700–$1,200 | Durable, paintable, energy-efficient |
| Aluminum-clad wood | $900–$1,600 | Low-maintenance exterior, wood interior |
Add 20–40% for triple-pane glass, 15–30% for argon/krypton gas fills, and significantly more for custom sizes or historic reproductions. For a tailored estimate, use our Window & Door Replacement Calculator.
Window Cost by Style
Window style affects price as much as material. Installed costs for a vinyl-frame window in 2026:
- Double-hung: $450–$700 — most common, both sashes tilt in for cleaning.
- Casement: $500–$800 — crank-out, great ventilation, more weatherstripping to wear.
- Slider: $450–$750 — slides horizontally, common in modern homes and basements.
- Picture (fixed): $500–$1,200 — large unoperable pane, priced by size.
- Bay or bow: $1,500–$4,000 — multi-window projection, structural and roofing work involved.
Full-Home Window Replacement
Most homeowners replace windows in batches or all at once. For a typical 2,000 sqft home with 10–15 windows:
| Material | 10 Windows | 15 Windows |
|---|---|---|
| Vinyl | $4,500–$7,000 | $6,750–$10,500 |
| Fiberglass | $7,000–$12,000 | $10,500–$18,000 |
| Wood | $8,000–$14,000 | $12,000–$21,000 |
Full-home replacement usually wins on per-unit cost — contractors discount for volume. Labor and disposal are also more efficient in one project.
Installation Type: Insert vs Full-Frame
Two installation methods affect cost significantly:
- Insert (pocket) replacement: New window fits inside the existing frame. Cheaper ($100–$200 less per window), faster, less mess. Works when the existing frame is solid and level.
- Full-frame replacement: Old frame comes out down to the rough opening. More expensive ($200–$400 more per window), but necessary when frames are rotted, warped, or you are changing window size.
A good contractor inspects frames before quoting and recommends insert where viable. A contractor pushing full-frame on every window may be inflating the bid.
Exterior Door Replacement Cost
Entry door replacement is one of the better-ROI exterior projects. Costs by material, installed:
| Door Material | Installed Cost | ROI |
|---|---|---|
| Steel | $500–$1,200 | ~65% |
| Fiberglass | $800–$2,000 | ~75% |
| Wood | $1,200–$2,500 | ~60% |
Fiberglass doors lead on ROI because they mimic wood, resist dents and rust, and insulate well. Steel is the budget pick but dents and conducts heat. Wood looks best but requires maintenance and warps in some climates. Adding sidelights or a transom window can push a door project to $3,000–$5,000.
Energy Savings Reality Check
Window companies love to quote energy savings, but the payback is often longer than advertised. Replacing single-pane windows with double-pane typically saves $100–$300 per year on heating and cooling — meaning a $10,000 project takes 30+ years to pay back on energy alone. The real value is comfort (fewer drafts, less noise), curb appeal, and resale. Treat energy savings as a bonus, not the primary justification.
Case Study: 12-Window Vinyl Replacement, Denver, Colorado
A homeowner replaced 12 double-hung windows (original 1985 aluminum units) with vinyl double-pane windows for $7,200. Breakdown: 12 windows at $475 each ($5,700), full-frame installation on 4 windows with rotted frames ($1,000 extra), disposal ($300), permits and inspection ($200). The contractor used insert installation on the 8 windows with intact frames, saving about $1,600 versus full-frame on all. Colorado labor runs slightly above the national average. Annual energy savings estimated at $180, with the bigger benefit being eliminated drafts and improved home value of about $4,800 — a 67% ROI.
