Quick answer
Most South Florida homeowners pay about $850–$1,850 per standard impact window installed, and roughly $16,500–$40,000 for a typical home with 12 to 20 openings. Impact entry doors average about $2,200–$4,900, two-panel impact sliding doors about $2,400–$4,850 and two-car impact garage doors about $5,000–$9,500. Size, window style, glass package, county rules and permits all move the price, so the only exact number is a measured quote.
The prices below are averages: we combined the price ranges we publish for our own work with the ranges published in 2026 price guides by other South Florida installers, then rounded. They are planning numbers for installed work, not quotes. Your exact price comes from a free in-home measurement.
Impact window prices in South Florida
| Window | Average installed price |
|---|---|
| Standard-size impact window (per window) | $850–$1,850 |
| Single-hung impact window | $800–$1,200 |
| Horizontal-roller (sliding) impact window | $1,400–$2,800 |
| Picture / fixed impact window | $1,200–$3,100 |
| Whole home, about 12–20 openings | $16,500–$40,000 |
Larger openings, custom shapes, second-floor installs and coastal homes that need higher design pressures land at the upper end. See our impact window replacement service for what is included.
Impact door and sliding glass door prices
| Door | Average installed price |
|---|---|
| Impact entry door, single | $2,200–$4,900 |
| Impact double / French door with sidelites | $4,750–$9,000 |
| Impact sliding glass door, 2-panel (6–8 ft) | $2,400–$4,850 |
| Impact sliding glass door, 3–4 panel (9–12 ft) | $4,250–$12,000 |
Very wide multi-panel sliders, typically 16 feet and up, are priced individually and can run well above these ranges. More on impact door installation.
Impact garage door prices
| Garage door | Average installed price |
|---|---|
| Impact-rated garage door, single-car | $2,750–$6,500 |
| Impact-rated garage door, two-car | $5,000–$9,500 |
The garage door is usually the largest opening in the house, and it counts toward the opening-protection credit on a wind-mitigation report. A heavier impact door may also need a stronger opener. See garage door repair and installation.

Permits and other costs
- Building permit: on average about $200–$1,000 per project, depending on the city and the scope. A reputable quote states whether the permit is included.
- County rules: Miami-Dade and Broward are in the High Velocity Hurricane Zone, so products must be approved for that standard; one 2026 guide estimates this adds roughly 10–15% compared with Palm Beach County.
- Structural changes: enlarging an opening or converting windows into a door is priced separately and changes the permit scope.
- Finish work: stucco, drywall and paint touch-ups around new openings should be listed on the quote, not discovered afterwards.
What changes the price?
- The number and size of openings — the biggest single factor.
- Window and door style: fixed glass and single-hung cost less than casements, large sliders and French doors.
- Glass package: low-E coatings, tints and obscure glass for bathrooms add cost but cut heat and glare.
- Frame finish and color, and whether grids are added.
- Location: coastal homes and upper floors often need higher design-pressure products.
- Access and removal: second-story openings and old window removal add labor.
How to lower the cost
- Insurance credits: once every opening is protected, file a wind-mitigation inspection — opening-protection credits can offset part of the cost every year.
- My Safe Florida Home: eligible owner-occupied single-family homes may qualify for the state’s matching hurricane-hardening grant, subject to eligibility and available funding.
- Repair what is repairable: a dragging slider often needs new rollers, not a new door, and foggy glass usually needs a new glass unit, not a new window — see our guides on sliding door service and foggy glass replacement.
- Shutters for rarely used openings: aluminum shutters cost less than impact glass where daily use and views matter less.
- Phase the project: some homeowners protect the most exposed elevations first and finish the rest later.

How we calculated these numbers
For each item we took the installed-price ranges we publish for our own work and the ranges published in 2026 price guides from other South Florida installers and window and door companies covering Miami, Fort Lauderdale and the wider region. We averaged the low ends and the high ends separately and rounded the results. Published prices come mostly from contractors, so treat them as planning ranges; quotes that include permits, finishing work and premium glass will sit higher than bare-product prices.
Frequently Asked Questions
How much does it cost to put impact windows in a whole house in South Florida?
For a typical single-family home with about 12 to 20 openings, the average installed cost is roughly $16,500–$40,000. Smaller condos and townhomes come in lower; large homes, oversized sliders and premium glass push the total higher.
Are impact windows more expensive in Miami-Dade and Broward than in Palm Beach?
Usually somewhat, because Miami-Dade and Broward are in the High Velocity Hurricane Zone and products must be approved for that stricter standard. One published 2026 guide estimates the difference at roughly 10 to 15 percent compared with Palm Beach County, but it depends on the product and the opening.
Do impact windows pay for themselves?
Partly, and sometimes substantially. Once every opening is protected and a wind-mitigation inspection is filed, Florida insurers apply opening-protection credits, you no longer need to buy, store or install shutters, and laminated insulated glass reduces cooling load. How fast that adds up depends on your policy and your home.
Why do impact window quotes vary so much?
Quotes differ in the product series and brand, glass package, design pressure, whether stucco and drywall repair, permits and debris removal are included, and how many openings change size. Compare itemized quotes that list each opening with its product approval number.
