Pricing reviewed October 2026
Impact-resistant (hurricane) windows typically cost $700 to $2,875 per window installed according to Angi (updated Oct 19, 2026). This Old House, citing Angi and HomeAdvisor data, puts the average at about $1,250 per window, with most installs between $1,175 and $1,350 (updated June 23, 2026). For a 22-window home, Angi estimates $15,400 to $63,250. All figures checked Oct 27, 2026.
Impact windows use laminated glass in a reinforced frame. The glass is designed to stay in the opening when wind-borne debris hits it. In hurricane-prone coastal areas they're often a code requirement, not an upgrade. They can also cut the windstorm part of your insurance premium and, in Florida, qualify for state matching grants. This guide covers what they cost, where they're required, and how to make sure you're paying for an approved product.
Impact window cost at a glance
| Item | Typical cost | Source (as of Oct 27, 2026) |
|---|---|---|
| Installed, per window | $700 – $2,875 | Angi |
| Installed, per window (average) | $1,250 (most $1,175 – $1,350) | This Old House |
| Installed, per window (broader range) | $300 – $1,700+ | This Old House |
| Window only, per sq. ft. | $30 – $60 | This Old House |
| Simplest single-hung in Florida, incl. permit | Starting at $1,200 – $1,500 | Naples, FL contractor quoted by Angi |
| Premium over a comparable standard window | 25% – 35% | Angi |
| Labor | $100 – $300 per window; up to $600 | Angi |
| Permit | About $50 per window | Angi |
| 10 windows / 22 windows | $7,000 – $28,750 / $15,400 – $63,250 | Angi |
Why the spread? Angi's range runs from small vinyl units up to large fiberglass ones. This Old House's $1,250 is an average for a typical window. The Naples contractor's $1,200–$1,500 floor reflects a real Florida market with permits included. If you live in Miami-Dade or Broward, budget toward the upper end. Products approved for the High-Velocity Hurricane Zone are the most demanding (see below).
Cost by frame material, style and size
| Frame (Angi) | Installed per window |
|---|---|
| Vinyl | $700 – $2,500 |
| Composite | $750 – $2,625 |
| Aluminum | $800 – $2,750 |
| Fiberglass | $850 – $2,875 |
| Style or size | Typical cost | Source |
|---|---|---|
| Single-hung | $300 – $950 | This Old House |
| Casement | $450 – $575 | This Old House |
| Horizontal sliding | $300 – $1,000 | This Old House |
| Small 24" × 24" casement | $700 – $800 | Angi |
| Medium 36" × 60" double-hung | About $1,800 | Angi |
| 12-ft sliding glass door | $8,000 – $9,000 | Angi |
| Custom hurricane bay or bow | Up to nearly $10,000 | Angi |
This Old House's style figures are well below Angi's size-based ones. That is another reason to price your actual openings rather than rely on one national number.
Where impact windows are required
FEMA's coastal construction guidance summarizes the model-code rule. In wind-borne debris regions, glazing must be impact-resistant or protected by an impact-resistant covering that meets ASTM E1996 and ASTM E1886 or another approved standard. Wood structural panels are allowed as an alternative within limits (FEMA Technical Fact Sheet 6.2). That fact sheet quotes the 2009 IBC and IRC. Under those editions, debris regions include areas within 1 mile of the coast where the basic wind speed is 110 mph or more, areas where it is 120 mph or more, and Hawaii. Current codes use updated wind maps, so your building department's map is the one that counts.
In Florida, Miami-Dade and Broward counties form the High-Velocity Hurricane Zone (HVHZ). The rest of the state is non-HVHZ, further divided by a wind-borne debris line (Miami-Dade Product Control brochure, as of Oct 27, 2026). Miami-Dade's Product Control Section approves building-envelope products, including windows and shutters, through a Notice of Acceptance (NOA). Before you sign, ask for the NOA or Florida Product Approval number for the exact window, size and design pressure being installed.
Insurance discounts, grants and tax credits
- Florida insurance. Florida law requires residential property insurance rate filings to include discounts, credits or deductible reductions for windstorm mitigation. The listed techniques include "opening protection" and "window, door, and skylight strength" (Fla. Stat. 627.0629, 2026). Your discount depends on your insurer and a wind-mitigation inspection.
- My Safe Florida Home. Grants are matched at $2 from the state for every $1 from the homeowner, up to a $10,000 state contribution. Windows are listed under opening protection, and the program may require all openings to be protected before it reimburses (Fla. Stat. 215.5586, 2026). Funding and application windows change, so check before you plan around it.
- Federal tax credit. The IRS says the Energy Efficient Home Improvement Credit (which covered up to $600 for qualifying windows) applies to property placed in service through December 31, 2025 (IRS, as of Oct 27, 2026). Windows installed in 2026 don't qualify under that credit.
Impact glass warranties are shorter
Read the glass section of the warranty. Several major makers cover laminated or impact glass for less time than standard insulated glass:
| Manufacturer document | Impact / laminated glass | Standard insulated glass |
|---|---|---|
| JELD-WEN warranty (products made on/after June 1, 2019) | ImpactGard glass units: 10 years | 20 years |
| Pella warranty brochure (vinyl lines incl. Hurricane Shield; correct as of 3/1/2024) | Laminated glass: 10 years | 20 years |
| Milgard replacement warranty (effective Jan 1, 2026) | Delamination of laminated/impact units: 10 years | Seal failure (obstructed vision): 20 years |
Pros and cons of impact windows
| Pros | Cons |
|---|---|
| Always-on protection, with no shutters to put up before a storm | Costs 25%–35% more than comparable standard windows (Angi) |
| Meets code for glazed openings in debris regions with an approved product | Shorter glass warranty terms at several brands |
| May qualify for Florida insurance credits and My Safe Florida Home grants | Heavier units and more anchoring mean higher labor |
| Laminated glass adds security and noise reduction | Federal efficiency tax credit no longer applies (2026 installs) |
Who impact windows are for
- Homes in wind-borne debris regions and the Florida HVHZ, where replacement glazing generally must be impact-rated or protected.
- Owners tired of shutters. Angi puts hurricane shutters at $1,475–$5,850 on average. Some owners keep them anyway for extra protection.
- Florida homeowners who can combine a wind-mitigation insurance credit with a state grant.
- Not necessary for most inland homes outside hurricane regions. Standard double-pane windows cost far less there; see window cost by type and window cost by material.
Comparing brands? Several of them make impact lines: Milgard vs. JELD-WEN, Andersen vs. Pella, and Pella vs. Simonton. Replacing old louvers? See jalousie window cost.

How much does it cost to put impact windows in a whole house?
Angi estimates $7,000–$28,750 for 10 windows and $15,400–$63,250 for 22 windows, the EPA average number of windows per home that Angi cites.
Are impact windows required?
In wind-borne debris regions, model codes require glazing to be impact-resistant or protected by an impact-resistant covering meeting ASTM E1996 and E1886. In Florida, Miami-Dade and Broward form the High-Velocity Hurricane Zone, where products need HVHZ approval such as a Miami-Dade NOA.
Do impact windows lower insurance in Florida?
Florida Statute 627.0629 requires residential property insurance rate filings to include discounts or credits for windstorm mitigation, including opening protection and window strength. The amount depends on your insurer and a wind-mitigation inspection.
Is there a grant for impact windows in Florida?
The My Safe Florida Home program (Fla. Stat. 215.5586) matches $2 of state money for every $1 from the homeowner, up to $10,000, for eligible mitigation including windows.
Can I still get a federal tax credit for impact windows?
The IRS says the Energy Efficient Home Improvement Credit applies to qualifying property placed in service through December 31, 2025, so windows installed in 2026 do not qualify under it.
