The honest answer is that a single impact window installed in Florida usually runs between $650 and $1,200, and a whole-home project lands somewhere around $12,000 to $25,000. Your number depends on how many openings you have, the size and shape of each one, the frame material you pick, and the condition of the walls behind the old windows. This guide breaks down what actually drives the price so you can budget with real figures instead of a vague range.
Average impact window cost in Florida
Most South Florida homeowners pay by the opening, not by the square foot, and installers quote a per-window price that already includes labor and permitting. Here is what typical openings cost once they are in and sealed.
| Window type | Typical installed price |
|---|---|
| Single-hung (standard bedroom size) | $650 – $950 |
| Double-hung | $800 – $1,200 |
| Casement | $900 – $1,400 |
| Sliding / horizontal roller | $1,000 – $1,800 |
| Picture / fixed (large) | $1,200 – $2,500 |
These are installed ranges for a standard retrofit, not bare product prices you might see online. A quote that only covers the window and leaves out labor, permits, and cleanup is not a real quote. When you compare bids, make sure each one includes the same scope.
What drives the price up or down
Number and size of openings
This is the biggest lever. A three-bedroom house with 12 to 15 openings costs far less than a waterfront home with two dozen large sliders and picture windows. Bigger glass also means thicker laminated units and heavier frames, which push the per-window price higher.
Frame material
Aluminum frames tend to cost less and carry more glass in a slim profile, which many South Florida homes prefer. Vinyl frames insulate better and often price a little higher. The right pick depends on your home and your priorities, and we walk through that in our guide on vinyl versus aluminum impact windows.
Glass package
Laminated impact glass is standard. If you add low-E coatings for heat control, upgraded interlayers for sound, or tinting, each option adds cost. Most homeowners see the best value in a mid-tier low-E laminated package.
Condition of the opening
If the installer opens the wall and finds rot, stucco damage, or an out-of-square frame, repairs add to the bill. Older homes almost always need some patching. A good estimator flags this during the site visit so it does not surprise you later.
Permits and inspections
Every county in South Florida requires permits and a final inspection for impact windows. Reputable installers build that into the price and handle the paperwork. If a bid looks unusually cheap, check whether it skips permitting, because unpermitted work can stall a future home sale.
Quick budgeting rule: Count your openings, multiply by roughly $900 for a mixed set of standard windows, then add a cushion for large sliders and any wall repairs. That gets you a ballpark before we ever visit.
Impact windows vs. cheaper protection
Impact windows cost more up front than hurricane shutters or plywood, and that gap is real. What you get for the difference is protection that stays in place year-round with nothing to deploy, plus energy savings, noise reduction, and an insurance benefit that chips away at the price over time. We compare the two side by side in impact windows vs. hurricane shutters, and we cover the payback math in are impact windows worth it.
Ways to lower your out-of-pocket cost
- Wind mitigation insurance credits. Impact windows can qualify you for premium discounts on the windstorm portion of your policy. See how that works in our post on impact windows and insurance discounts.
- Do the whole house at once. Bundling every opening into one project usually earns a better per-window rate than replacing a few at a time.
- Finance the project. Monthly plans spread the cost so you can protect the whole home now instead of waiting. We lay out the options on our financing page.
- Time it outside peak season. Demand spikes when a storm is in the forecast. Booking in the off-season often means faster scheduling and better pricing.
What a fair quote looks like
A trustworthy estimate is itemized. It lists each opening, the window type and series, the glass package, permit fees, labor, and the warranty. It should also name the product line so you can look it up.
