Window and Door Replacement Costs: A GC's Pricing Breakdown
Replacing windows and exterior doors is one of the most visible home improvements you'll make, and costs vary wildly depending on materials, energy ratings, and your region. As a licensed GC, I've replaced hundreds of windows—here's what you actually need to know.
Window Types and Costs
Double-Hung Windows are the workhorse. They tilt inward for easy cleaning and fit most home styles. Vinyl double-hung runs $300–$800 per window installed. Fiberglass, which holds paint better and resists warping, costs $600–$1,200.
Casement Windows (hinged like a door) offer better air sealing and a European look. Budget $400–$1,000 per window. They work great for kitchen sinks or bathrooms where you want the sash to swing out.
Picture Windows are large, fixed panes with no operable sashes—basically a view frame. Cost $500–$2,000 per window. Combine them with operable casements or double-hungs on the sides for ventilation.
Bay and Bow Windows are multi-pane projections that add dimension to a room. These are the pricey ones: $1,500–$3,500 per unit installed. They look great but create thermal bridging challenges.
Frame Materials Matter
Vinyl dominates the market because it's durable, low-maintenance, and affordable. Expect $300–$1,200 per window depending on size and energy rating.
Fiberglass is stronger and takes paint forever. It resists warping better than wood, especially in humid climates. Add 30–50% to vinyl pricing for the same size.
Wood looks gorgeous and ages well in some climates, but demands maintenance. You're painting or staining every 7–10 years. Wood windows cost $800–$2,500 per unit. I use them for historical homes or where aesthetics demands it.
Aluminum is rare in residential now because it conducts heat poorly, but you'll see it on commercial doors and sunrooms. Not recommended for primary windows.
Energy Ratings: U-Factor and SHGC
The two numbers that matter:
- U-factor measures heat loss. Lower is better. Anything 0.30 or below qualifies for federal tax credits. If you live in Minnesota or Maine, aim for 0.25 or below.
- SHGC (Solar Heat Gain Coefficient) measures solar heat transmission. In cold climates, you want higher SHGC (0.50+) to capture winter sun. In hot climates, go low (0.20–0.30).
Triple-pane windows always outperform double-pane on U-factor but cost 20–30% more. In cold climates, the energy savings justify it. In moderate climates, double-pane with good coatings is fine.
Installation Labor and Permits
Installation runs $100–$300 per window on average. Some crews charge per opening; others give a project flat rate. Always get it in writing.
Permit costs typically range $150–$400 depending on your jurisdiction. A few municipalities waive permits for like-for-like replacements in the same opening. Always check first—I've seen surprise reinspections kill deals at closing.
Removal of old windows is included in most bids, but ask. Disposal of old frames and trim adds 50–100 dollars per window in some markets.
Exterior Door Replacement
Entry Doors (front/back) cost $400–$1,500 for the door itself, plus $200–$400 for installation. Solid wood or fiberglass doors with multi-point locks run toward the high end. Hollow core doors are cheaper but feel cheap.
Sliding Glass Doors (for patios) cost $800–$2,500 depending on size and frame material. Vinyl is fine here; the door takes less abuse than entry doors.
Storm Doors add $200–$600 and extend the life of your entry door. Good value if your main door is exposed to weather.
Window and Door Replacement Cost Table
| Component | Vinyl | Fiberglass | Wood |
|---|---|---|---|
| Double-hung window | $300–$800 | $600–$1,200 | $800–$1,800 |
| Casement window | $400–$1,000 | $700–$1,300 | $1,000–$2,000 |
| Picture window | $500–$2,000 | $900–$2,500 | $1,200–$3,000 |
| Bay window | $1,500–$3,500 | $2,200–$4,500 | $2,500–$5,000 |
| Entry door | $400–$1,200 | $600–$1,500 | $800–$2,000 |
| Installation per unit | $100–$300 | $150–$350 | $200–$400 |
Prices are national averages and vary by region, size, and energy rating.
Federal Tax Credits and Incentives
The Inflation Reduction Act offers up to $3,200 in federal tax credits for energy-efficient window and door upgrades (2024–2025). You need:
- Windows with a U-factor of 0.30 or below
- Entry doors with a U-factor of 0.20 or below
- Maximum $500 per window, $500 per door
Fiberglass and wood doors rarely hit the 0.20 threshold, but many vinyl entry doors do. Check the NFRC label before you buy.
What People Get Wrong
Myth 1: "Bigger is always better for energy savings." Reality: A triple-pane window that's thermally broken beats a cheap double-pane every time. Glass quality matters more than quantity.
Myth 2: "You can recover costs in 5 years." Reality: In most climates, payback is 10–15 years. Buy them for durability, resale appeal, and comfort—the energy savings are a bonus.
Myth 3: "DIY installation saves thousands." Reality: Improper installation creates air leaks that kill energy performance. I've seen bad installs cause water intrusion and mold. Hire pros.
