Window Replacement Cost in 2026: Per Window and Whole House Prices
You get three quotes for new windows and the numbers do not even look related. One says $500 a window. Another says $1,200. The third lumps everything into a single total. That confusion is normal. The window replacement cost depends on frame material and glass and style and how many openings you have. It also depends on which survey you trust.
This guide lays the main sources next to each other so you can see the real spread. We use Fixr and Pella and a 2026 homeowner survey published by This Old House. When their numbers clash we show both. When a figure is our own math we say so.
Window Replacement Cost at a Glance
Start with the per window price. The three sources disagree so read all three rows.
| Source | Average or typical installed cost per window |
|---|---|
| This Old House survey (2026) | $517 average |
| Fixr | $800 average with a typical range of $450 to $1,200 |
| Pella (vinyl) | $800 to $1,600 |
Why the gap? The survey averages what real homeowners reported across many window types. Fixr gives a broad market range. Pella prices by material and its vinyl range starts at the level where Fixr averages out. We cannot say which is right for your home. We can say that a quote below $450 per window deserves a question and a quote above $1,600 for a plain window deserves two.
Window Replacement Cost by Frame Material
The frame is the biggest price lever after size. Here is how the sources compare.
| Frame material | Fixr (per window) | This Old House survey (per window) | Pella (installed) |
|---|---|---|---|
| Aluminum | $200 to $800 | $453 | Not listed |
| Vinyl | $350 to $800 | $472 | $800 to $1,600 |
| Composite | $300 to $2,500 | $513 | Not listed |
| Wood | $600 to $2,000 | $544 | $1,100 to $2,200 or more |
| Fiberglass | $400 to $1,500 | $564 | $1,100 to $2,200 |
Fixr's own text says wood runs $400 to $2,000 while its table says $600 to $2,000. We show the table value. Vinyl is the budget pick in every source. Fiberglass and wood cost more. Wood has the longest lifespan according to Fixr but it asks for more upkeep. That upkeep point is our own note and not from the sources.
Cost by Glass Package
The glass inside the frame changes the price too. The survey gives this breakdown:
| Glass package | Average cost per window |
|---|---|
| Single pane | $400 |
| Double pane | $529 |
| Triple pane | $609 |
Double pane adds about $129 over single pane in the survey. Triple pane adds about $80 more. Fixr lists glass upgrades such as tempered or laminated glass at $100 to $800 per window. Ask which glass package is in the quote. A low price often means the base package.
Cost by Window Style
Style affects hardware and labor. The survey found a narrow spread across eight common styles. Fixr found a wide one.
| Style | This Old House survey | Fixr range |
|---|---|---|
| Single hung | $474 | $250 to $700 |
| Double hung | $551 | $300 to $1,000 |
| Casement | $529 | $400 to $1,200 |
| Sliding | $531 | $700 to $1,500 |
| Picture | $540 | $300 to $1,600 |
| Awning | $545 | $300 to $800 |
| Bay | $550 | $900 to $4,500 |
| Glass block | $505 | $400 to $1,300 |
The survey says the eight styles averaged $474 to $551 each. Fixr also lists bow windows at $1,500 to $8,000 and garden windows at $1,000 to $4,000. Pella says single hung and double hung windows sit at the lower end and bay and bow assemblies sit at the high end. Bay and bow windows are where quotes jump the most.
What You Pay for Labor and Extras
Labor is a large slice of the bill. Fixr says labor is about 30% of the total. It puts smaller windows at $150 to $300 each in labor and large bow or bay windows at up to $800.
Other costs that show up on quotes:
- Permits. Fixr says $50 to $300 on average.
- Glass upgrades. $100 to $800 per window by Fixr.
- Structural repairs. Fixr says a few hundred dollars or thousands depending on rot or water damage.
- Second story work. The survey says second story work raises labor and Fixr says large windows cost more.
- Haul away. Fixr gives no price. Ask if it is in the quote.
Fixr says insert replacement costs a reduced fee compared with full-frame replacement but gives no dollar figure. An insert fits into the existing frame. A full-frame job removes the old frame too. Full-frame costs more but it lets the installer fix hidden rot. If you suspect water damage ask for a full-frame quote.
Whole House Window Replacement Cost
Most people want one number for the whole house. Fixr gives these totals:
| Home size | Number of windows | Fixr total |
|---|---|---|
| Single story | 10 to 15 | $8,000 to $12,000 |
| Two story | 15 to 30 | $12,000 to $24,000 |
Fixr also shows these brackets by count: 5 to 10 windows cost $2,250 to $12,000. A count of 11 to 20 runs $4,950 to $24,000. A count of 21 to 25 runs $9,450 to $30,000. The ranges are wide because of the style and material mix.
The survey reports an average project of $7,183 across an average of 7 windows. Here is a puzzle. Seven windows at the survey average of $517 comes to $3,619. That is about half of the reported project total. The page does not explain the gap. It may reflect extras such as trim and repairs and bigger windows. We cannot confirm that. So treat the per window price as a base and the project total as the number people actually paid.
Sample Budgets Using These Ranges
These are our own multiplications of the published ranges. They are not quotes.
Five vinyl windows. At Pella's $800 to $1,600 each the total is $4,000 to $8,000.
Ten vinyl windows. At Pella's range the total is $8,000 to $16,000. That fits with Fixr's $8,000 to $12,000 for a single story home.
Ten fiberglass windows. At Pella's $1,100 to $2,200 each the total is $11,000 to $22,000.
One bay window. Fixr says $900 to $4,500 before extras. Budget for framing work around it.

Surprises That Raise the Final Bill
The survey asked homeowners how the final price compared with the quote. The results are worth reading before you sign.
- 61% paid about the same as quoted.
- 27% paid more than their original quote.
- 14% reported unexpected costs.
- 11% needed follow-up work.
- 9% had wall or trim damage.
More than a quarter paid above the quote. Ask the contractor what happens if they find rot behind the old frame. Get the answer in writing. Also ask who repairs the trim and the interior paint. If you plan to repaint after the install our house painting cost guide helps you budget that step.
Is Window Replacement Worth It?
The survey asked about energy bills. Among double pane owners 36% reported lower monthly bills. Of those who saw savings the most common range was $25 to $49 per month or about $300 to $588 per year. In the Midwest 39% reported lower bills. That is not a guaranteed saving. Most owners did not see a drop.
Fixr puts the return on investment at 60% to 85% depending on materials. Energy efficient windows can reach the top of that range. Pella says savings and resale impact vary by home and market. The survey also found that 94% of homeowners were satisfied and 61% were very satisfied.
Our view is simple. Replace windows because they are broken or leaking or rotting. Do not replace them only to chase an energy bill. The payback is slow and uneven.
Repair or Replace?
Sometimes a repair is enough. The survey says repair is better for isolated issues such as worn weatherstripping. Replace when you see extensive damage or recurring drafts or poor operation or several problems at once.
Common reasons the survey found:
- Damaged frames or sills. This became a more common reason than energy efficiency in 2025.
- Broken glass. The most common reason in homes 10 years old or newer.
- Aging windows. The most common reason in homes more than 20 years old.
- Drafts and fogging. The survey lists drafts and fogging and deteriorating frames. Pella lists drafty and hard to operate windows.
If the problem is only a leaky seal try our guide on how to reseal windows before you spend thousands. That repair costs a fraction of a new window.
Windows in Tiny Homes
Small homes have fewer windows but each one matters more. Natural light makes a small space feel bigger. Heat loss through glass hits a small home hard because there is little wall to absorb it. We did not find a source with pricing for tiny home windows alone. Use the per window ranges above and check our tiny homes cost guide to see where windows sit in the whole build.
How to Lower Your Window Replacement Cost
- Get three itemized quotes. List the window type and the glass package and the labor and the trim.
- Replace only what you must. Replace the failing windows first. Phase the rest.
- Choose vinyl for budget. Every source lists it as the lowest cost mainstream frame.
- Pick standard sizes. Custom sizes raise the price.
- Check for rebates. Look at utility and state programs. We did not verify any current offers.
- Ask about timing. Off-season installs sometimes cost less. That is a common tip and we found no source that prices it.
Big window jobs often come with roof or HVAC work. If you are planning those too read our roof replacement cost guide and the home renovation cost guide to build a full budget.
Quick Decision Guide
- One or two bad windows: repair or replace only those.
- Whole house on a budget: vinyl double pane in standard sizes.
- Wet climate or rot risk: ask for full-frame installs.
- Large bay or bow window: expect the highest quote and ask about framing.
- Not sure: get three itemized quotes.

Not always. In the survey 36% of double pane owners saw lower bills and the common saving was $25 to $49 per month. Fixr puts the return at 60% to 85%. Replace for condition first.
What is the difference between insert and full-frame replacement?
An insert fits into the existing frame and costs less. A full-frame job removes the frame and lets the installer fix rot behind it. Fixr gives no dollar gap between the two.
How often do windows need replacing?
The survey points to age and damage. Aging windows were the top reason in homes older than 20 years. Fixr says wood has the longest lifespan but gives no number of years.
Final Thoughts on Window Replacement Cost
The window replacement cost runs from about $450 to $1,600 per window for most homes. The sources differ so use the range and not a single number. Material and glass and style decide where you land.
Get itemized quotes and ask what happens if rot appears. Repair small problems and replace the failing windows first. That keeps the bill honest and the house warm.
