If you are a homeowner in Miami-Dade, Broward, or Palm Beach County, you already know that impact-resistant doors and windows are not optional. Florida's High Velocity Hurricane Zone (HVHZ) building code demands them for new construction and major renovations, and more homeowners every year are upgrading voluntarily for the insurance savings, energy efficiency, and peace of mind they deliver.
The single most common question we hear at National Glass is simple: how much will it cost? The honest answer is that pricing varies significantly based on your home's size, the products you select, and the scope of installation work required. This guide gives you real numbers drawn from South Florida market data so you can plan your budget with confidence.
Whether you are pricing a full-house replacement or looking to upgrade just a few key openings, the tables and breakdowns below will help you understand what to expect. We also cover financing options, insurance savings, hidden costs, and strategies to reduce your total investment without sacrificing storm protection.
How Much Do Impact Windows Cost in Miami?
Impact windows in Miami typically range from $40 to $100+ per square foot installed, depending on the window style, frame material, glass configuration, and the complexity of the installation. That per-square-foot figure includes the window unit itself, installation labor, permitting, and basic finishing.
For most homeowners, it is easier to think in terms of per-window cost. Here is what you can expect for the most common window types, fully installed, in the Miami market as of 2026:
Impact Window Costs by Type (Installed)
Single-Hung (36" x 60")
Horizontal Sliding (48"-72" x 48")
Picture / Fixed (48"-72" x 60"-72")
Casement (30"-36" x 48"-60")
Single-hung windows are the most affordable because they are the most common residential size and have the simplest operating mechanism. Sliding windows cost more as sizes increase, particularly for wide openings common in Florida living rooms. Picture windows carry a premium because the glass lite is larger (no dividing rail), and casement windows require more complex hardware for their crank-out operation.
These ranges assume standard aluminum frames and clear impact laminated glass. Upgrading to Low-E coatings, tinted glass, or vinyl frames will shift prices toward the higher end of each range. Custom sizes or unusual shapes (arched tops, geometric windows) can push costs above the ranges listed here.
How Much Do Impact Doors Cost in Miami?
Impact doors generally cost more per unit than windows because they are larger, heavier, and require more robust framing and hardware. Doors also carry higher structural demands since they are primary entry and exit points that must meet both impact and forced-entry standards.
Impact Door Costs by Type (Installed)
Entry Door (Single, 36" x 80")
Sidelights optional; premium designs higher
Sliding Glass Door (2-4 panel, 6'-8' wide)
Most popular impact door type in South Florida
French Doors (Double, 5'-6' wide)
Both panels operable; synchronized locking hardware
Pivot Door (Oversized, 4'-5'+ wide)
Dramatic size and specialized pivot hardware
Entry doors span a wide range because material and design options vary dramatically. A basic fiberglass impact entry door with a simple panel design sits near the lower end, while a premium decorative impact door with sidelights and a transom can easily exceed $5,000. Sliding glass doors are the most popular impact door type in South Florida, and pricing depends heavily on the number of panels and the overall opening width.
French doors command higher prices because both panels are operable and require synchronized locking hardware that meets impact testing standards. Pivot doors represent the top of the market: their dramatic size and specialized pivot hardware put them in a category of their own. If you are considering a custom pivot door, expect to invest $8,000 to $12,000 or more for a fully installed unit that meets HVHZ requirements.
Factors That Affect Price
No two homes are priced identically. Understanding the variables that drive cost up or down will help you evaluate quotes and make trade-offs that match your budget. Here are the primary factors.
Size of the Opening
Larger openings require more glass, more frame material, and heavier structural support. Oversized products also require special handling during installation, adding to labor costs.
Glass Type and Low-E Coatings
Low-E coatings reduce cooling costs by 15-25% vs clear impact glass. Tinted glass and insulated (dual-pane) configurations add cost but deliver meaningful energy performance.
Frame Material
Aluminum frames are standard and most affordable. Vinyl offers better thermal insulation. Premium options like fiberglass or thermally broken aluminum deliver superior energy performance at higher cost.
Design Pressure (DP) Rating
Higher DP ratings cost more. Your Florida building code requirements for location and elevation directly influence costs. DP50 costs less than DP70.
Brand and Manufacturer
Popular brands like PGT, ES Windows, MrGlass, and ECO each occupy different price tiers. Premium brands carry higher tags but may offer superior aesthetics or performance.
Number of Openings
Volume matters. Whole-house projects achieve better per-unit pricing because mobilization, permitting, and project management costs are spread across more units.
Installation Complexity
Straightforward replacements are most affordable. Costs rise when openings need resizing, access is difficult, or existing framing needs structural reinforcement.
Structural Modifications
Older homes may need steel lintels, reinforced wall sections, or upgraded tie-down systems. These modifications add cost but are essential for proper performance.
Impact Windows vs Shutters: Cost Comparison
One of the most frequent comparisons Miami homeowners make is between impact windows and hurricane shutters. Shutters have a lower upfront cost, but the full picture is more nuanced. Here is a side-by-side comparison of the two most common approaches:
| Factor | Accordion Shutters | Impact Windows |
|---|---|---|
| Cost per Sq Ft (Installed) | $15 – $20 | $40 – $100+ |
| Typical Whole-House Cost | $5,000 – $15,000 | $15,000 – $50,000+ |
| Storm Preparation Required | Yes — must close before storm | None — always protecting |
| Insurance Discount | Moderate | Maximum available credit |
| Energy Savings | None | $400 – $1,000/year |
| Noise Reduction | Only when closed | Year-round (STC 32-40) |
| Home Value Impact | Minimal | Increases value 5-10% |
| Aesthetic Impact | Visible tracks and housing | Clean, modern appearance |
| Lifespan | 15 – 20 years | 25 – 30+ years |
While accordion shutters cost roughly one-third to one-half the price of impact windows upfront, impact windows deliver dramatically better long-term value. The combination of higher insurance savings, year-round energy efficiency, increased property value, and zero maintenance or deployment effort makes impact windows the superior investment for most Miami homeowners who plan to stay in their home for five or more years.
That said, a hybrid approach can work well for budget-conscious homeowners. You might install impact windows on the primary living spaces and visible facades while using accordion shutters on utility areas, garages, or secondary bedrooms. Your contractor can help you determine where code allows this combination and where impact-rated products are required.
Average Whole-House Costs
A typical Miami home has between 15 and 25 window and door openings. The total cost for a full-house impact window and door replacement generally falls in the $15,000 to $50,000+ range, with most mid-size homes (1,500 to 2,500 sq ft) landing between $20,000 and $35,000.
| Home Size | Typical Openings | Estimated Total Cost |
|---|---|---|
| Small (under 1,500 sq ft) | 8 – 14 | $10,000 – $22,000 |
| Medium (1,500 – 2,500 sq ft) | 15 – 22 | $20,000 – $35,000 |
| Large (2,500 – 4,000 sq ft) | 22 – 35 | $30,000 – $50,000 |
| Luxury / Custom (4,000+ sq ft) | 35+ | $50,000 – $100,000+ |
These estimates include standard aluminum-framed impact windows and doors with clear laminated glass, professional installation, permitting, and basic finishing (caulking, trim). Premium product selections, structural modifications, or homes with very large openings will push costs toward the upper end of each range.
Keep in mind that the per-unit cost decreases as the project scope increases. A full-house replacement typically achieves a 10-15% cost efficiency compared to replacing the same windows one or two at a time over several years. Additionally, a single permit covers the entire project, saving on repeated permit fees.

The True ROI of Impact Windows & Doors
Impact windows and doors are one of the few home improvements that actively pay you back. The return on investment comes from insurance savings, energy efficiency, and increased home value, often recovering the full cost within 7 to 12 years.
Three Channels of Return
Insurance Premium Savings
Florida law requires wind mitigation discounts. Impact windows qualify for the highest credits, with annual savings typically ranging from $1,000 to $3,000 per year.
Energy Efficiency Savings
Modern impact glass with Low-E coatings reduces solar heat gain, lowering cooling costs. Homeowners typically save $400 to $1,000 per year on energy bills.
Home Value Increase
Impact windows increase South Florida home values by 5 to 10 percent. On a $500,000 home, that translates to $25,000 to $50,000 in added value.
Break-Even Analysis Example
Consider a typical scenario: a homeowner invests $30,000 in a full-house impact window and door installation. Here is how the payback accumulates:
| Savings Category | Annual Savings | 10-Year Total |
|---|---|---|
| Insurance Premium Reduction | $2,500 | $25,000 |
| Energy Bill Savings | $600 | $6,000 |
| Home Value Increase (at sale) | — | $25,000 – $50,000+ |
| Combined Annual Cash Savings | $3,100 | $31,000 |
In this example, the annual cash savings alone recover the full $30,000 investment in under 10 years. When you factor in the home value increase realized at sale, the return is significantly higher. Few home improvements in South Florida offer this combination of immediate cash flow benefits and long-term equity growth.
Financing Options
A full-house impact window and door project is a significant investment, but several financing programs make it accessible for homeowners at a range of budget levels. Here are the most common financing options available in South Florida:
How to Get an Accurate Quote
Not all quotes are created equal. A reliable impact window and door quote should be based on an in-person measurement of your home, not a phone estimate or rough online calculator. Here is what to look for and what to watch out for.
Questions to Ask Your Contractor
- Are you licensed and insured in Miami-Dade County?
- Do you handle the permitting process, and is the permit fee included in the quote?
- Which manufacturers and product lines do you carry?
- Do the products have a valid Miami-Dade NOA (Notice of Acceptance)?
- What is the lead time from order to installation?
- What does your installation warranty cover, and for how long?
- Will you provide the documentation I need for a wind mitigation inspection?
- Do you offer financing or work with PACE programs?
We recommend getting at least three quotes from licensed contractors. Compare not just the bottom-line price but the products specified, the scope of work included, and the warranty terms. The lowest price is rarely the best value when it comes to hurricane protection for your home.
