What Impact Windows Actually Cost in South Florida
Impact windows cost between $400 and $1,800 per window installed in Florida, with most homeowners paying $800 to $1,400. A typical whole-home project covering 15 to 20 windows runs $12,000 to $25,000 fully installed — including permits, removal of old windows, and cleanup.
That range is wide because the final price depends on your window type, frame material, glass options, the county you live in, and the condition of your existing openings. A standard single-hung vinyl window in a non-HVHZ area costs far less than a custom architectural aluminum window in Miami-Dade. This page breaks down every factor so you know what to expect before your first estimate.
The prices below reflect what we see in the field every day across Broward, Miami-Dade, and Palm Beach counties — not recycled averages from a national publisher. We have installed impact windows on over 3,000 homes and commercial properties over the past two decades. Where competitors cite HomeAdvisor data, we cite our own project history.
Impact Window and Door Cost by Type
Not all window styles cost the same. Operating hardware, frame complexity, and glass area drive the differences:
Single-Hung
Bedrooms, bathrooms, standard openings
$400 – $900
Sliding (Horizontal)
Florida rooms, lanais, wide openings
$500 – $1,100
Casement
Maximum ventilation, tightest seal
$550 – $1,200
Picture / Fixed
View walls, stairwells, no ventilation needed
$350 – $800
Awning
Bathrooms, kitchens — ventilate during rain
$500 – $1,100
Architectural / Custom
Non-standard shapes, arched, geometric
$800 – $1,800+
Impact Doors
Sliding Glass Doors
Patio and pool access, Florida rooms
$1,800 – $4,500
French Doors
Entry, formal spaces, large openings
$2,000 – $5,000+
Single-hung windows are the most common and least expensive because their hardware is simple and manufacturers produce them at scale.
Custom and architectural windows — arched tops, trapezoids, or oversized fixed panels — cost more because they are manufactured to order and require custom framing during installation.
Impact Window Cost by Frame Material
Frame material affects price, performance, and longevity. In Florida, the two dominant choices are vinyl and aluminum:
Baseline
Vinyl
$400 – $1,100
per window installed
- Best insulation value
- Corrosion-proof
- Lowest cost
Best for: Budget-conscious, residential, inland homes
Limitations: Thicker sightlines, limited colors, large openings (60"+) push structural limits
60–70% of our residential installs
+15–30%
Aluminum
$600 – $1,500
per window installed
- Strongest, thinnest frames
- Largest openings possible
- Salt-air resistant
Best for: Coastal, modern, large openings, condos, salt air zone
Limitations: Conducts heat (needs thermal break), higher cost
Standard for high-rise and waterfront
+40–60%
Wood-Clad
$900 – $1,800+
per window installed
- Interior wood aesthetic
- Exterior protection
- Historic properties
Best for: Historic districts, high-end custom where review board requires wood
Limitations: Highest cost, very few HVHZ-rated products, maintenance-intensive in humid climates
Rare in South Florida
Vinyl is the right choice for most single-family homes where budget matters and window sizes are standard. Modern formulations use titanium dioxide stabilizers and fusion-welded corners that hold up well in Florida heat, though very large openings can push vinyl frames to their structural limits.
Aluminum is the standard for high-rise condos, coastal homes within the salt air zone (3,000 feet of saltwater), and any project requiring large spans or thin sightlines. The cost premium is 15–30% over vinyl for the same window size. If your home is directly on the water or above the third floor, aluminum is usually the better long-term investment.
Wood-clad impact windows exist but are rare in South Florida. Very few manufacturers produce wood-clad products that carry a Miami-Dade NOA, and the ongoing maintenance requirements make them impractical for most homeowners.

What Drives the Price: Why Quotes Vary So Much
If you've gotten two quotes for the same house and been baffled by a $10,000+ difference — you're not alone. Here's why it happens:
1
Window Size Matters More Than Window Count
A 24×36" bathroom window costs a fraction of a 48×72" living room window. Two homes with the same number of windows can have dramatically different project costs if one has large picture windows and sliding glass doors. Tip: Compare quotes on a per-square-foot basis, not per unit, for an apples-to-apples comparison. Typical range: $55–$100 per square foot installed.
2
Glass Options Add Up
Standard laminated impact glass is the base. Upgrades include:
- Low-E coating: +$30–$80/window — reflects heat, recommended for west/south-facing windows
- Insulated glass (IG): +$50–$120/window — best thermal and acoustic performance
- Tinted glass: +$20–$50/window — reduces glare and solar heat gain
- Acoustic glass: +$40–$100/window — maximizes noise reduction, ideal near airports or highways
3
Your County Determines Which Products Qualify
Miami-Dade and Broward counties are High Velocity Hurricane Zones (HVHZ) — every product must carry a Miami-Dade County Notice of Acceptance (NOA). NOA-approved products cost 10–20% more than standard FBC-approved products due to stricter missile impact and pressure cycling testing. In Palm Beach County, coastal areas fall under partial HVHZ requirements, while inland areas have lower requirements.
4
Permit and Inspection Costs Vary by Jurisdiction
Florida requires a building permit for window replacement. Costs and timelines differ by county:
- Miami-Dade: $300–$800 — NOA documentation adds processing time
- Broward: $250–$600
- Palm Beach: $200–$500
5
Structural Modifications Add Cost
If existing openings need resizing, headers need reinforcement, or stucco has water damage, that's additional work. Common in homes built before 1990. Adds $200–$800 per opening. A retrofit installation into existing frames costs less than a full-frame replacement where the entire frame is removed and rebuilt. A reputable installer identifies these needs during the measurement visit — not after demolition.
6
Installation Quality Is the Invisible Cost Driver
The biggest legitimate reason for price differences between companies. Proper impact window installation includes structural anchoring to the building frame, continuous sealant bead, backer rod and foam insulation, flashing integration with exterior waterproofing, and final inspection sign-off. A crew that cuts corners quotes less — and the window leaks during the next tropical storm. The window is only as good as its installation.
7
Manufacturer Matters
PGT/CGI, ES Windows, WinDoor, and Lawson all price differently and offer different product lines. We source from multiple manufacturers to match each project's specific needs rather than pushing a single brand.
Impact Window Cost by Project Size
Here is what whole-project costs look like for common scopes:
Single window replacement
1 opening
$500 – $1,500
Partial home (bedrooms, front)
5 – 8 openings
$3,500 – $10,000
Typical whole home
1,200 – 2,000 sqft 15 – 20 openings
$12,000 – $25,000
Large home / estate
2,000 – 3,000+ sqft 25 – 40+ openings
$25,000 – $55,000
Condo unit
Varies 5 – 12 openings
$4,000 – $15,000
Whole-home projects carry a lower per-unit cost than single-window replacements because the installer mobilizes once, pulls one permit, and achieves repetition efficiency. If you plan to do the whole house eventually, doing it all at once is almost always more cost-effective.
Condo projects may involve additional coordination with the HOA or condo association, which may require specific manufacturers, colors, or installation methods. Ask your association for their approved product list before getting quotes.
Thinking About Doing It in Phases?
Many homeowners start with the most vulnerable openings — large sliding glass doors and front-facing windows — then complete the rest in a second phase. We can plan your project in stages while keeping the per-unit cost competitive.

How Impact Windows Pay for Themselves
Impact windows are not just a hurricane expense — they return value through multiple channels:
Insurance Savings
15–45% off windstorm premiums
= $450–$2,250/year on a typical South FL policy
Florida law (Section 627.0629) requires insurers to offer wind mitigation discounts. All openings must be protected for the full credit on the OIR-B1-1802 form.
Energy Savings
15–25% lower cooling costs
= $300–$800/year in South Florida

Property Value
3–5% home value increase
= $15,000–$25,000 on a $500K home

Avoided Storm Damage
Average FL claim: $40,000+

Net Cost Analysis
A $20,000 whole-home project with $1,500/year in combined insurance and energy savings has an effective payback period of 8–10 years — and the windows last 25–30+ years. Add the property value increase and avoided storm damage, and the investment often pays for itself before the first major storm.
No More Shutter Hassle
If you currently use shutters or plywood, impact windows eliminate the pre-storm scramble — permanent, 24/7 protection with zero setup labor. For snowbirds or homeowners with mobility limitations, this convenience alone justifies the investment.

Why are insurance savings this high? From 2006 to 2017, the U.S. experienced what climatologists call "The Hurricane Drought" — a 12-year stretch without a single major hurricane landfall, unprecedented in the modern record. When Hurricanes Irma (2017), Ian (2022), and Milton (2024) ended the lull, Florida insurers recalibrated. Premiums have more than tripled in many markets since 2019, making wind mitigation discounts worth far more today than at any point in the past two decades.

Impact Windows vs. Hurricane Shutters: Cost Comparison
Shutters cost less upfront but cost more in every other way:
$12,000 – $25,000
- Zero maintenance — no annual upkeep
- Zero pre-storm setup — always protected
- Highest insurance tier — opening protection A
- 15–25% energy savings on cooling costs
- Noise reduction — STC 28–35
- +3–5% home value increase
- 25–30+ year lifespan
$3,000 – $8,000
- Annual lubrication and track cleaning
- 2–6 hours to deploy per storm
- Same insurance tier if all openings covered
- No energy savings
- No noise reduction when not deployed
- Minimal home value impact
- 15–20 year lifespan
Most of our customers who start with shutters end up switching to impact windows within 3–5 years. The ongoing inconvenience, forgone energy savings, and limited daily benefits make the upfront cost difference smaller than it appears on paper.

Frequently Asked Questions About Impact Window Costs
Most Florida homeowners pay $800–$1,400 per impact window installed, though costs can range from $400 for a basic single-hung vinyl window to $1,800 or more for large custom or architectural windows. The price depends on the window type, frame material, glass options, and your county's building code requirements.
A typical whole-home impact window replacement covering 15–20 openings costs $12,000–$25,000 installed in South Florida. Larger homes with 25–40 openings can run $25,000–$55,000. These ranges include permits, old window removal, installation, and cleanup.
For Florida homeowners, impact windows are one of the best investments you can make. Beyond hurricane protection, they reduce insurance premiums by 15–45% on the windstorm portion, lower energy bills by 15–25%, increase home value by 3–5%, provide 24/7 security, and block 99% of UV rays. Most homeowners recover the cost through insurance and energy savings within 8–12 years.
Yes. Florida law requires insurers to discount premiums for homes with wind mitigation features. Impact-rated windows and doors qualify for the highest opening protection credit on the wind mitigation inspection form (OIR-B1-1802). Savings typically range from 15–45% on the windstorm portion of your policy. All openings must be protected to receive the full credit.
Fixed picture windows are the least expensive per unit because they have no operating hardware. Among operating windows, single-hung vinyl impact windows offer the lowest cost, typically starting around $400–$500 installed for standard sizes.
Impact windows with a Miami-Dade County Notice of Acceptance (NOA) typically cost 10–20% more than products approved only under the general Florida Building Code. The NOA requires additional missile impact testing at higher wind speeds (175 mph vs. 140 mph). NOA-approved products are required in Miami-Dade and Broward counties.
No. Florida building code requires a licensed contractor to install impact windows, and a building permit with inspections is mandatory. Improper installation voids the product warranty, will not pass inspection, and creates failure points during storms.
Quality impact windows last 25–30 years or more with minimal maintenance. The laminated glass does not degrade, and modern frame materials are engineered for Florida's UV exposure, humidity, and salt air. Hardware may need replacement after 15–20 years. Clean glass and frames with mild soap quarterly and inspect seals for cracks annually.
Yes. Homes with impact windows sell for 3–5% more in Florida's hurricane-prone markets. On a $500,000 home, that translates to $15,000–$25,000 in additional value. Impact windows also reduce time on market, as buyers in South Florida actively seek properties with existing hurricane protection.
Yes. PACE financing requires no money down and no credit check. The My Safe Florida Home program provides matching grants up to $10,000. Traditional financing with $0 down and monthly payments is also widely available. See our financing options for details.
Impact sliding glass doors typically cost $1,800–$4,500 installed, depending on size, frame material, and glass options. Large multi-panel sliders or French doors with impact glass can exceed $5,000.
Hurricane shutters cost less upfront ($3,000–$8,000 for a whole home vs. $12,000–$25,000 for impact windows). However, impact windows provide year-round energy savings, equivalent insurance discounts, noise reduction, UV protection, and eliminate shutter deployment labor. Most homeowners who try shutters eventually upgrade to impact windows within 3–5 years.
This is generally not recommended. Mixing window types weakens your home's overall storm resistance, and Florida building code in wind-borne debris regions requires all openings to be protected. You also will not qualify for the full wind mitigation insurance discount unless every opening has impact-rated protection.
A Design Pressure rating measures how much wind force a window can withstand — the higher the number, the stronger the window. In South Florida, residential impact windows typically need a DP rating of 40–65+ depending on your location and floor level. Your installer should match the DP rating to the specific wind load requirements at your address. Look up your address to see your design wind speed and the DP rating you need.
