Most homeowners pay somewhere between a few hundred dollars and about $1,500 per standard window once installation is included, and a whole house usually lands in the thousands to low tens of thousands. HomeGuide’s 2026 cost guide puts the typical range at $450 to $1,500 per window, or $4,500 to $22,500 for the 10 to 15 windows in an average home.
Where your project falls inside that spread depends on four things: the frame material, the window style, the glass package and how much work the opening needs. This guide walks through each one with published price ranges so you can read a quote with confidence.

Key takeaways
- HomeGuide puts average replacement at $450 to $1,500 per window installed, and $4,500 to $22,500 for 10 to 15 windows.
- Frame material is the biggest single lever: aluminum and vinyl sit at the low end, wood and fiberglass at the high end.
- Style matters too. Picture and single-hung windows are the cheapest, bay and bow units the most expensive.
- Labor typically runs $100 to $500 per window, according to HomeGuide, and climbs when the frame or surrounding wall needs repair.
- In a hot, humid climate like ours, low solar heat gain glass is worth budgeting for because cooling drives the energy bill.
What the average window replacement costs
Two national cost guides give a useful picture of the market. HomeGuide reports $450 to $1,500 per window installed, with the window unit alone running $250 to $1,400 or more before labor.
HomeAdvisor’s 2026 data looks at the whole project instead. It reports that most window installation jobs cost between $3,436 and $11,837, with an average of $7,347.
Those two numbers aren’t in conflict. HomeAdvisor’s project totals reflect how many windows people typically replace at once, while HomeGuide’s per-window figure helps you scale up for your own house.
Whole-house totals by window count
HomeAdvisor breaks its project data out by the number of windows. These are its reported ranges, which are handy for a quick sanity check on a quote.
| Number of windows | Reported project range |
|---|---|
| 6 to 8 | $4,500 to $6,000 |
| 8 to 12 | $6,000 to $9,000 |
| 12 to 16 | $9,000 to $12,000 |
| 16 to 20 | $12,000 to $15,000 |
| 20 to 24 | $15,000 to $18,000 |
| 25 | $18,000 to $20,000 |
HomeGuide’s range for 25 windows is wider, at $11,250 to $37,500, because it includes larger custom sizes and premium wood units at the top end.
Window replacement cost by frame material
The frame is where most of the price difference lives. It also decides how much upkeep you’ll do for the next couple of decades, so it’s worth choosing on more than the sticker.
Here’s how HomeGuide prices each common frame material, installed, per window.
- Aluminum: $175 to $1,000. HomeGuide calls it the cheapest option but notes it isn’t as durable or energy efficient as other materials.
- Vinyl: $350 to $1,500. One of the most popular residential choices for its durability and efficiency.
- Fiberglass: $400 to $2,000. HomeGuide says it tends to last longer than all other frame materials.
- Composite: $400 to $2,300. Blends of polymers and wood fiber that aim for the look of wood with the upkeep of vinyl.
- Wood: $800 to $3,800. Classic and common in historic districts, but it needs more maintenance and is susceptible to rot.
Manufacturer pricing can run higher than these survey averages. Pella’s own 2026 cost guide lists installed vinyl at $800 to $1,600 per window and fiberglass and wood at $1,100 to $2,200 or more, reflecting its product lines rather than the whole market.
Pella also points out that vinyl offers built-in resistance to moisture, which helps keep maintenance needs relatively low. In a city where humidity sits high most of the year, that’s a practical point in vinyl’s favor.
Cost by window style
Style changes the price because it changes the hardware, the glass area and how much labor the install takes. A fixed picture window has no moving parts, so it’s usually cheaper than an operating window of the same size.
These are HomeGuide’s installed ranges for the styles we see most on local homes:
- Single-hung: $300 to $2,100
- Picture: $300 to $1,300
- Sliding: $300 to $2,300
- Double-hung: $350 to $2,500
- Casement: $400 to $3,000
- Awning: $400 to $2,000
- Garden: $1,000 to $4,000
- Bay: $2,000 to $6,000
- Bow: $3,000 to $8,000 or more
Brand averages
Brand moves the number as well. HomeAdvisor lists average per-window costs that run from about $1,100 for Milgard and $1,150 for Champion up to $1,550 for Larson and $1,600 for Harvey, with Andersen at $1,175 and Pella at $1,250.
Treat those as a rough guide only. Each brand sells several product lines, and the line you pick inside a brand often matters more than the name on the label.
If you’re replacing like for like, the style is mostly decided for you. You can compare the options on our window types page.
