| HomeAdvisor (2025 data, updated Jun 2026) | $12,442 average; $4,613 – $20,436 normal range; $55 to $100 per square foot | Matches Angi at the headline; sibling relationship disclosed |
| Fixr (updated Aug 2025) | $2,090 national average for a set of 8 storm windows; $1,505 – $2,737 average range; $812 low end to $8,032 high end | Separately published from the figures above, with no shared sourcing stated; scoped to 8 windows |
Cost per window
| Basis | Cost | Source |
|---|---|---|
| Per window (typical range) | $90 – $400 | HomeAdvisor (2025 data) |
| Exterior, per square foot (standard size) | $55 | Angi/HomeAdvisor (matching) |
| Exterior, per square foot (custom size) | $100 or more | Angi/HomeAdvisor (matching) |
| Interior, per square foot | $24 | Angi/HomeAdvisor (matching) |
Angi figures are from a 2026 guide; the matching per-square-foot figures on the sibling pages are not independent corroboration.
Cost by size (Angi & HomeAdvisor, matching)
| Size (inches) | Average cost |
|---|---|
| 24 x 30 | $275 |
| 32 x 36 | $440 |
| 48 x 44 | $810 |
| 52 x 44 | $875 |
| 52 x 60 | $1,190 |
| 60 x 60 | $1,375 |
| 60 x 96 | $2,200 |
The two sibling publishers carry this table at identical figures – matching figures alone don’t establish independent corroboration. HomeAdvisor scopes its table to one fixed window with no moving parts, excluding labor.
Cost by size (Fixr, 2025, materials only)
| Size (inches) | Average cost |
|---|---|
| 24 x 30 | $46 – $84 |
| 32 x 36 | $73 – $134 |

| 52 x 44 | $116 – $211 |
| 52 x 60 | $169 – $307 |
| 60 x 60 | $199 – $363 |
| 60 x 96 | $337 – $613 |
Fixr’s table is materials only – a different scope from the table above, kept separate rather than compared directly.
Cost by frame material
| Frame material | Average cost per window | Source |
|---|---|---|
| Aluminum | $90 – $275 | Angi/HomeAdvisor (matching) |
| Vinyl | $100 – $300 | Angi/HomeAdvisor (matching) |

| Wood | $129 – $235 | $322 – $586 | Fixr (2025) |
The Fixr table is materials only, so it is kept separate rather than compared directly. Note the material ordering differs between publishers – the source pages don’t explain why.

|---|---|---|
| Fixed | $100 – $300 | Fixr (2025) |

| Triple-track | $150 – $400 | Fixr (2025) |
| Two-track slider | $150 – $400 | Fixr (2025) |
Different scopes, kept separate rather than compared directly.

Angi reports plexiglass at around $300 per window as the most affordable option in its guide, and notes tempered glass pushes project totals toward the $34,000 high end.
Labor costs
| Item | Cost | Source |
|---|---|---|
| Labor per window | $30 – $200 | Angi/HomeAdvisor (matching) |
| Labor per hour | $30 – $100 | Angi/HomeAdvisor (matching) |

| Labor per window | $67 – $123 | Fixr (2025) |

| Item | Cost | Source |
|---|---|---|
| Stabilizer bars | $20 – $40 per bar | All three publishers (matching) |

The stabilizer-bar match combines the corporate siblings with one separately published figure; the pages state no shared sourcing. The weatherstripping figures have very different scopes and are kept separate.
Removal and ongoing costs
| Item | Cost | Source |
|---|---|---|
| Old storm window removal | $10 – $20 per window | Angi (2026) |
| Old window removal (added to replacement) | $50 per window | HomeAdvisor (2025 data) |

| Repairs | $25 – $200 per window | Angi (2026) |
