Impact windows cost $700 to $2,875 per window installed per Angi’s 2026 data, with an average of $1,800 for a prefab unit.1 HomeGuide puts the installed range at $400 to $1,200 per window,2 and This Old House reports a narrower average of $1,175 to $1,350.3 Prices below are the latest published national figures* from each source.
*National figures, not local quotes. Angi’s page is labeled 2026 data (updated October 19, 2026), This Old House’s guide was updated June 23, 2026, and HomeGuide’s article (titled 2026) is dated June 2023 with no update date shown. Your price depends on window size, style, frame material, and how many windows you replace.

What sources say
| Source | Figure | Scope |
|---|---|---|
| Angi | $700 – $2,875 installed; $1,800 average prefab; low $125, high $10,000 | Impact window projects on its platform (2026 data, updated Oct 19, 2026) |
| HomeGuide | $400 – $1,200 installed ($300 – $800 unit + $100 – $400 labor) | Hurricane window cost guide (titled 2026; article dated June 2023) |
| This Old House | $1,250 average; most installs $1,175 – $1,350 | Hurricane window cost guide (updated June 23, 2026) |
The published spreads differ widely, and the sources do not establish why. This Old House states that its cost data is based on estimates from Angi and HomeAdvisor, yet its published range is much narrower than Angi’s current page; the guide does not explain the difference.1,3 Treat each figure as that source’s own published number, not as points on one agreed scale.
Cost per window by frame material
The three sources measure different things here, so the tables are labeled by basis: Angi prices the full installed window, HomeGuide prices the unit alone, and This Old House prices frame material.
| Frame material | Angi (installed) | HomeGuide (unit only) | This Old House (frame material) |
|---|---|---|---|
| Vinyl | $700 – $2,500 | $300 – $600 | $100 – $300 |
| Aluminum | $800 – $2,750 | $200 – $400 | $90 – $275 |
| Fiberglass | $850 – $2,875 | $350 – $700 | — |
| Composite | $750 – $2,625 | — | — |
| Wood | — | $400 – $800+ | $175 – $400 |
All three sources agree on the ordering: aluminum frames are the budget option, and wood or fiberglass sit at the top.1,2,3 HomeGuide notes vinyl, fiberglass, and wood insulate better than aluminum, while This Old House notes aluminum remains common in coastal areas for its strength despite lower energy efficiency.2,3
Whole-home project totals
Angi recommends replacing every window for full protection, since one failed window can let storm pressure destabilize the structure; it cites EPA data that the average home has 22 windows.1
| Number of windows | Angi (installed) | HomeGuide (installed) |
|---|---|---|
| 5 | $3,500 – $14,375 | $2,000 – $6,000 |
| 10 | $7,000 – $28,750 | $4,000 – $12,000 |
| 15 | $10,500 – $43,125 | $6,000 – $18,000 |
| 20 | $14,000 – $57,500 | $8,000 – $24,000 |
| 25 | $17,500 – $71,875 | $10,000 – $30,000 |

Cost by window style
| Style | HomeGuide (installed) | This Old House (average range) |
|---|---|---|
| Fixed / picture | $400 – $750 | — |
| Single-hung | $400 – $950 | $300 – $950 |
| Double-hung | $500 – $1,100 | — |
| Casement | — | $450 – $575 |
| Sliding | $600 – $2,300 | $300 – $1,000 (horizontal) |
| Architectural | $500 – $2,400 | — |
Angi adds size-specific examples: a small 24-inch casement runs $700 to $800, a medium 36-by-60 double-hung about $1,800, and a 12-foot sliding glass door $8,000 to $9,000.1 This Old House’s size table (unit plus installation) starts lower, at $100 to $200 for a 19-by-26 window and up to $850 to $1,700 for a 53-by-76.3 The two size tables do not overlap, and the sources do not establish why their entry sizes are priced so far apart.
Brand pricing
| Brand | Installed cost per window (HomeGuide) |
|---|---|
| Champion | $400 – $1,200 |
| CGI | $400 – $2,400 |
| Jeld-Wen | $600 – $1,900 |
| Kolbe | $700 – $900 |
| Pella | $800 – $2,000 |
| Andersen | $1,200 – $2,500 |
HomeGuide notes well-known brands such as PGT, Andersen, and Pella cost more than average and tend to carry higher performance ratings.2
Labor, permits, and extras
| Item | Cost (source) |
|---|---|
| Labor per window | $100 – $300, up to $600 for large or hard-to-reach windows (Angi) |
| Labor per window | $100 – $400, or $30 – $65 per hour (HomeGuide) |
| Labor per window | $30 – $200; retrofit installs cost less than full-frame or masonry work (This Old House) |
| Permit | typically $50 per window (Angi); $50 – $200 (HomeGuide) |
| Weather stripping | $5 – $10 per window (HomeGuide) |
| Stabilizer bars | $20 – $40 per window (HomeGuide) |
| Ventilation stops | $10 – $50 per window (HomeGuide) |
| Interior trim | $100 – $250 per window (HomeGuide) |
| Hurricane shutters (add-on) | $35 – $350 per window (HomeGuide) |
The labor ranges do not agree across sources, and none of them explains the spread.1,2,3 Angi notes contractors often discount per-window rates on large multi-window jobs.1
Impact premium vs standard windows
Angi puts impact windows at 25 to 35 percent more than comparable standard windows.1 HomeGuide adds that replacing a standard window with a hurricane window costs about $25 to $50 more per window than installing one in new construction, and that enlarging or reframing an opening raises the price further.2
Where the Florida code requires protected openings
The 2023 Florida Building Code, Residential (8th Edition, effective December 31, 2023) defines windborne debris regions as areas within 1 mile of the mean high water line where an Exposure D condition exists upwind at the waterline and the ultimate design wind speed is 130 mph or greater, plus all areas where the design wind speed reaches 140 mph or more. In those regions, Section R301.2.1.2 requires exterior glazed openings to be protected against windborne debris, but the protection does not have to be impact windows: coverings tested to ASTM E1886 and E1996, TAS 201, 202 and 203, or AAMA 506 qualify.4
Angi’s guide states the Florida Building Code requires impact-resistant windows within a mile of the coast where wind speeds can reach 110 mph; the adopted code text sets the threshold at 130 mph, adds the Exposure D condition, and accepts approved coverings, so impact glazing is one way to comply, not the only one.1,4 The code also carves out a limited exception for wood structural panel shutters, which carries its own sizing, span, and attachment conditions and should be confirmed with the local building department before relying on it.4 Areas designated High-Velocity Hurricane Zones follow stricter provisions of the code, so local requirements can be tighter than the statewide baseline.4 This Old House recommends verifying ASTM E1886/E1996 certification and the window’s Design Pressure rating when comparing products.3
Hurricane, impact, and storm windows
HomeGuide and This Old House both warn the terms get used interchangeably but describe different products. Hurricane or impact windows use laminated glass and reinforced frames built for extreme wind and flying debris; storm windows are add-on panes installed over existing windows for insulation and noise reduction and do not meet hurricane codes.2,3 Storm windows cost $150 to $400 per window installed, well below impact window pricing.2
Worth it?
HomeGuide lists safety during storms, UV blocking, energy efficiency, and reduced home insurance as the benefits, against high upfront cost and the fact that some styles do not open.2 This Old House adds that hurricane windows can add long-term value through insurance discounts and resale appeal, and recommends professional installation for code compliance and warranty coverage.3 Neither source publishes a specific insurance-discount figure.
