Window replacement is one of the most heavily marketed home improvement services, which means it is also one of the most commonly overpriced. National brands often quote $800-$1,500 per window for mid-range vinyl that independent installers offer for $350-$700. Understanding the real pricing helps you avoid the markup.
Window Cost by Material
| Material | Cost per Window (Installed) | 15-Window Home | Lifespan |
|---|---|---|---|
| Vinyl | $300–$700 | $4,500–$10,500 | 20–40 years |
| Wood | $600–$1,200 | $9,000–$18,000 | 30–50+ years |
| Fiberglass | $500–$1,500 | $7,500–$22,500 | 30–50+ years |
| Aluminum | $350–$800 | $5,250–$12,000 | 20–30 years |
| Wood-clad (exterior aluminum) | $700–$1,500 | $10,500–$22,500 | 30–50+ years |
Cost by Window Type
| Window Type | Cost per Window (Installed) |
|---|---|
| Double-hung | $300–$900 |
| Casement | $350–$950 |
| Sliding | $250–$800 |
| Picture (fixed) | $300–$1,200 |
| Bay/Bow | $1,000–$3,500 |
| Egress (basement) | $1,500–$5,000 |
The Big Brand Markup Problem
National window companies (Renewal by Andersen, Pella, Window World) often charge $800-$1,500 per window for products that independent installers offer for $350-$700. The product is similar — the markup covers their massive advertising budgets. Get quotes from at least one local independent installer alongside any national brand to see the price difference.
What Affects Cost
Full frame vs. insert replacement: Insert (pocket) replacement fits a new window inside the existing frame — faster and cheaper ($250-$700). Full frame replacement removes everything including the frame and trim ($400-$1,200) but is necessary when the frame is rotted or you want to change the window size.
Glass packages: Double-pane Low-E glass is the standard. Triple-pane adds $100-$200 per window and is most valuable in extreme climates. Argon gas fill (standard) vs. krypton (premium) makes a marginal efficiency difference.
Trim and casing: Interior and exterior trim work after installation can add $50-$200 per window if the existing trim does not fit the new windows.
Red Flags
“Today-only” pricing after an in-home consultation: This is the signature high-pressure sales tactic of the national window companies. Legitimate pricing does not expire in 24 hours.
Per-window price over $1,000 for standard vinyl: Unless these are very large or specialty-shaped windows, standard double-hung vinyl should not exceed $700-$800 installed.
No mention of Low-E coating: Any modern replacement window should have Low-E glass. If the quote does not mention it, the contractor may be installing outdated or builder-grade glass.
