Impact Window Cost in Miami
Every line we quote, with the range and the source behind it. Checked October 2026 against Miami-Dade and South Florida contractor pricing.
An impact window in Miami runs $1,000–$2,400 installed for a single-hung and $1,200–$2,800 for a casement or double-hung, which is roughly $40–$85 per square foot. A whole house of 15 to 20 openings usually lands $18,000–$45,000. Doors are their own thing: an eight-foot slider is $3,500–$6,000.
16 of the 18 rows below are grounded in published Miami-Dade or South Florida contractor pricing checked in October 2026. The rest are marked trade-typical, meaning we are telling you what the work normally costs rather than pointing at a source. We would rather label those than let them pass.
| Job | Range | Where the figure comes from |
|---|---|---|
| Single-hung impact window, installed | $1,000–$2,400 | Miami-Dade contractor: single-hung impact $1,000–$2,400. |
| Double-hung or casement, installed | $1,200–$2,800 | Same Miami-Dade source: double-hung $1,200–$2,800; a statewide guide puts entry-tier aluminum single-hung at $1,000–$1,500 and premium architectural units at $2,400–$3,800. |
| Picture or fixed window, installed | $700–$1,900 | Trade-typical. A fixed unit has no operating hardware, so it sits below a single-hung of the same size. Trade-typical, not sourced. |
| Per square foot, installed | $40–$85 | Miami-Dade County $40–$85 per sq ft installed; wider South Florida sources quote $40–$100+ depending on style and glass. |
| Whole home, 15–20 openings | $18,000–$45,000 | Contractor estimate for 15–20 windows: $18,000–$45,000. |
| Partial job, 8–12 openings | $8,000–$22,000 | Derived from the per-window range, and consistent with a published Miami HVHZ condo job of 10 units at $13,200 (about $1,320 each). |
| Impact slider, two-panel 6 ft | $1,500–$3,000 | South Florida guide: 6 ft two-panel $1,500–$3,000. |
| Impact slider, two-panel 8 ft | $3,500–$6,000 | Two independent South Florida guides agree on $3,500–$6,000 installed. |
| Impact slider, three-panel 9–12 ft | $5,000–$9,000 | South Florida guide: 3-panel $5,000–$9,000. |
| Multi-panel pocketing slider | from $15,000 | South Florida guide: multi-panel pocketing $15,000–$40,000+. |
| Impact entry door, single | $1,200–$2,800 | Miami-Dade installer $1,200–$2,200 installed; a Florida guide gives $1,500–$2,800 retail for a standard 36×80. |
| Entry door with sidelights | $2,500–$5,000 | Trade-typical. Sits between a single door and a double, because the sidelights are rated glass in their own frames. Trade-typical, not sourced. |
| Double entry or French doors | $4,500–$8,500 | South Florida guide: double-door configurations $4,500–$8,500 installed. |
| Miami-Dade permit, per project | $350–$600 | One guide gives $350–$600 per project; per-opening figures cluster at $150–$400. Fees are set by municipality, so the number is a range and not a formula. |
| HVHZ coastal premium | +15–25% | Contractor: properties within about a mile of the coast carry a 15–25% premium. |
| NOA code-compliant product premium | +10–15% | Contractor: Miami-Dade and Broward add 10–15% for mandatory NOA-rated products. |
| Structural engineering, where needed | $500–$1,500 | South Florida contractor checklist. |
| Labor only, per window | $250–$350 | Florida specialist installer labor-only rate. |
These prices are estimates. They are here so you know the scale before you call. Impact units are priced per opening, and the only number that counts is the written one you get after someone has measured. The measure is free.
What actually moves the number
- Size and style of each opening. Operating windows cost more than fixed ones; large spans cost more per square foot, not less.
- How close you are to the water. Higher required wind pressure ratings mean heavier frames and stronger glass.
- Glass choice. Low-E and tinted laminated glass cost more than clear and are worth it in this climate.
- Frame material. Aluminum is the Miami default; vinyl and composite price differently.
- What is behind the frame. Rotten bucks, stucco repair or a header that needs attention are real work, and they show up as their own lines.
- Access. A second story, a balcony with no elevator access, or a high-rise with a service elevator booking all add hours.
How to compare two quotes properly
Ask both for the same four things and the cheap one often stops being cheap: the Miami-Dade NOA number for the exact product, the glass and frame specification, whether the permit is included, and whether removal and disposal are included. Then compare per opening rather than on the total.
What is not in these numbers
Window treatments, interior trim beyond basic patching, and any structural work beyond the opening itself. If your job needs engineering, that is the $500–$1,500 line and we will say so at the measure rather than later.
FAQ
Questions about cost
Why is the range so wide?
Because a window is priced per opening. A small fixed bathroom window and an eight-foot casement in a corner of a waterfront house are both 'a window', and they are an order of magnitude apart. The per-square-foot figure is the fairest way to compare quotes.
Why are Miami prices higher than the rest of Florida?
Two reasons, and both are real. Miami-Dade is a High Velocity Hurricane Zone, so the products must carry a Miami-Dade Notice of Acceptance, which costs more than a product rated only to the statewide code. And near the coast the required wind pressure ratings climb again.
Is the permit included in your quote?
Yes, and so is removal and disposal of the old units. If a quote you are comparing is notably cheaper, check whether those two lines are in it. They are the usual omissions.
Does the price change if my frames are bad?
It can. If an opening has a rotten buck or stucco that has to be cut back and rebuilt, that is extra work and it goes on the quote as its own line after the measure. We would rather find it at the measure than on install day.
Can I do the house in stages?
Yes. Many people do the most exposed elevation first. The one thing to know is that wind mitigation credit generally needs every opening protected, so partial work usually will not move the insurance until the house is finished.
Are there grants or financing?
Florida has run a matching-grant program for home hardening in recent years, and whether it is open and funded changes. We will tell you what we know at the time, but check with the state rather than taking a contractor's word for it.

A range tells you the scale. A measure tells you the price. We come out, measure every opening and leave you a written figure per opening with no obligation to use it.
If the honest answer is that your existing windows have years left, that is what you will be told.
