Quick math: count your windows and multiply. A standard three-bedroom home has 10 to 12; at Angi’s $750 average that is $7,500 to $9,000 — the same $7,000 to $9,000 Angi quotes for that house type with standard double-hung windows.1 Labor is $100 to $300 of each window, about a fifth of the mid-range price.1
Cost by number of windows
| Windows replaced | Angi (double-hung, pro install) | HomeGuide (single-hung) |
|---|---|---|
| 6 – 8 | $4,500 – $6,000 | — |
| 8 – 12 | $6,000 – $9,000 | — |
| 10 | — | $4,500 – $15,000 |
| 12 – 16 | $9,000 – $12,000 | — |
| 15 | — | $6,750 – $22,500 |
| 16 – 20 | $12,000 – $15,000 | — |
| 25 | $18,000 – $20,000 | $11,250 – $37,500 |
HomeGuide’s bands are wider because they span basic aluminum through premium wood frames; Angi’s assume standard double-hung replacements.12 Replacing everything at once usually lowers the per-window price — ask for bulk pricing before phasing the project.13
Cost by frame material
| Frame material | Per window (Angi) | Installed (HomeGuide) |
|---|---|---|
| Aluminum | $75 – $400 | $175 – $1,000 |
| Vinyl | $100 – $900 | $200 – $1,500 |
| Composite | $300 – $1,200 | $400 – $2,300 |
| Wood | $150 – $1,300 | $800 – $3,800 |
| Fiberglass | $500 – $1,500 | $400 – $2,000 |
Vinyl is the popular middle: low-maintenance, energy-efficient, mid-price.1 Wood tops the range and needs ongoing sealing against rot.12 Fiberglass lasts the longest with no maintenance.1 Custom finishes or oversized windows add 25% to 50% to material costs.1
Cost by window style
| Style | Per window (Angi) | Installed (HomeGuide) |
|---|---|---|
| Single-hung | $100 – $400 | — |
| Double-hung | $150 – $650 | $350 – $2,500 |
| Picture | $65 – $700 | $300 – $1,300 |
| Casement | $150 – $1,000 | $400 – $3,000 |
| Awning | $400 – $950 | $400 – $2,000 |
| Egress | $100 – $700 | $3,000 – $7,000 |
| Bay | $900 – $7,100 | $2,000 – $6,000 |
| Bow | $1,500 – $6,500 | $3,000 – $8,000+ |
| Skylight | $900 – $2,500 | — |
The egress row shows how much definitions matter: Angi’s $100 to $700 covers the window unit, while HomeGuide’s $3,000 to $7,000 includes cutting and digging the code-required basement well. Same word, very different job.12
Glass and efficiency options
| Glass type | Per window (Angi) |
|---|---|
| Single-pane | $200 – $500 |
| Double-pane | $500 – $2,000 |
| Triple-pane | $1,000 – $4,000 |
| Tempered | $200 – $700 |
| Low-E | $300 – $1,100 |
Double-pane with Low-E coating is the mainstream choice; triple-pane earns its premium mainly in cold climates.1 In Florida and coastal states with hurricane codes, impact windows start at $1,200 to $1,500 per window installed, permitting included.1
Worked examples
Example 1 — three-bedroom house, 10 to 12 windows. 10 × $750 = $7,500 and 12 × $750 = $9,000 at Angi’s average, matching its published $7,000 to $9,000 estimate for exactly this house.1
Example 2 — 15 windows at HomeGuide’s range. 15 × $450 = $6,750 and 15 × $1,500 = $22,500 — identical to HomeGuide’s per-count table, so its table is simple multiplication with no volume discount baked in.2 Ask for that discount; both Angi and Fixr say it exists.13
Example 3 — labor share on a mid-range vinyl window. A $975 mid-range installed window with $200 of labor (midpoints of the published ranges) means about 20% of the bill is labor and 80% is the unit — so shopping the window itself matters more than negotiating the install. Our arithmetic from Angi’s figures.1
FAQ
Is it cheaper to replace all windows at once? Usually yes — installers commonly discount per-window pricing on whole-house jobs.13
Which frame material is the best value? Vinyl for most homes: low maintenance, efficient, mid-priced. Fiberglass if you want the longest lifespan.1
Are new windows worth it for energy savings? Double-pane Low-E glass improves temperature consistency and can trim heating and cooling bills; triple-pane pays off mainly in cold climates.13
Why are bay and bow windows so expensive? They project from the wall and need structural support — $900 to $7,100 for bay and $1,500 to $6,500 for bow.1
Do I need a permit? Often, especially for new openings or impact windows in hurricane zones, where permitting is typically bundled into the quote.1
