🪟 Window Replacement Cost: 2026 Pricing Guide

Window replacement is one of the most aggressively marketed home improvement services — meaning it's also one of the most overpriced. High-pressure sales tactics, "today only" offers, and confusing product tiers make windows notoriously difficult to price. Here's the straightforward breakdown.

Window Replacement Costs in 2026 (Per Window, Installed)

All prices include the window unit and standard installation (labor, disposal of old window, basic trim repair):

• Standard double-hung, vinyl, entry-level: $350–$600
• Standard double-hung, vinyl, mid-grade (Simonton, Pella 150): $500–$900
• Double-hung, fiberglass, mid-grade: $700–$1,300
• Double-hung, premium (Andersen 400 series, Pella Architect): $900–$1,800
• Casement windows: $600–$1,500 each
• Bay or bow window (factory unit): $2,500–$5,500
• Sliding glass door replacement: $1,200–$3,500
• Egress window (basement, with well): $2,500–$5,000

For a typical whole-house replacement (12–15 standard windows), expect $7,000–$18,000 for mid-grade vinyl windows and $12,000–$25,000+ for premium fiberglass or wood-clad windows.

Window Pricing: Frame Material Matters

• Vinyl (uPVC): Most affordable, good insulation, low maintenance. Doesn't take paint well. 90% of residential replacements are vinyl.
• Fiberglass: Stronger than vinyl, can be painted, better for extreme climates. Costs 30–60% more than comparable vinyl.
• Wood-clad (aluminum or fiberglass exterior, wood interior): Premium look, higher cost, requires interior maintenance. Andersen, Pella, and Marvin are the major brands. Add 50–100% over vinyl pricing.
• Aluminum: Commercial grade, less common in residential. Conducts cold — not ideal for cold climates without thermal breaks.

What Affects Window Replacement Costs

• Window size. Oversized windows, specialty shapes (arched, geometric), and custom sizes cost significantly more — often 2–5x a standard double-hung. Standard sizes (available in stock) are dramatically cheaper.
• Pocket replacement vs. full-frame replacement. Pocket (insert) replacement reuses the existing frame. It's faster and cheaper ($100–$200 less per window) but doesn't address frame rot or air leaks in the frame itself. Full-frame replacement removes everything to the rough opening and is appropriate for older windows with wood frame deterioration.
• Glass packages. Double-pane is standard. Triple-pane adds $50–$200 per window and is most beneficial in very cold climates. Low-E glass coatings are standard on quality windows and included in mid-grade pricing. Tempered glass (required in bathrooms, near doors) adds $50–$150 per window.
• Installation complexity. Second-floor windows require ladder work or scaffolding. Windows in difficult locations (over cabinets, tight spaces, historic frames) add $50–$200 per window in labor.
• Lead paint remediation. Pre-1978 homes may have lead paint on window frames. EPA RRP rules require lead-safe practices that add $15–$50 per window in compliance costs.

Red Flags in Window Quotes

• "Today only" pricing or high-pressure sales. The window industry is notorious for this tactic. Companies like Window World, Renewal by Andersen, and many regional retailers use "today only" discounts as a standard sales technique. The discount doesn't disappear tomorrow — they're built into the initial inflated price. Always get competing quotes.
• Pricing not broken out by window. If you're quoted "$14,000 for 12 windows" without per-window pricing, you can't verify what you're paying or compare quotes. Insist on itemized per-window pricing.
• Vague product descriptions. "Premium double-pane vinyl" describes half the windows on the market. Insist on brand, series, and model number before signing.
• Very low bids from unlicensed contractors. Windows installed improperly (incorrectly shimmed, inadequately flashed, poor caulking) are a major source of water intrusion and mold. The $100/window savings from a bargain installer often leads to $2,000+ in water damage.
• Including trim work without specifying extent. "Trim included" might mean re-caulking the interior sill or might mean full interior casing replacement at $150–$300 per window. Specify what's included in terms of trim repair.

What a Fair Window Quote Looks Like

For a whole-house replacement of 12 standard double-hung windows with mid-grade vinyl windows (Simonton, Pella 150, or equivalent), pocket replacement in good existing frames, expect $6,000–$10,000 installed in most U.S. markets. Coastal and high-cost metros run $8,000–$14,000. Any quote more than 40% above these ranges deserves a detailed explanation.

Don't Get Pressured Into Overpaying

Window companies invest heavily in sales training for a reason — their margins are high. Before signing any window contract, run the quote through QuoteScore. We'll benchmark each window against real market pricing and tell you if you're being quoted fairly or if it's time to get another estimate.
