Ask three contractors for a number and you’ll get three different answers. Installed impact window costs run anywhere from $700 to nearly $3,000 per window, and the spread comes down to three things: window size, frame material, and how close the house sits to the water.
On the Gulf Coast, that last factor matters more than people expect.
| Tier | Frame | Cost Per Window (Installed) |
|---|---|---|
| Entry | Aluminum single-hung | $700 – $1,200 |
| Mid-range | Vinyl or aluminum casement, Low-E glass | $1,200 – $2,000 |
| Premium | Custom/architectural, insulated laminated glass | $2,000 – $3,000+ |
Sliding glass doors run separately, usually $2,000 to $6,000+ each depending on panel count and size.
Escambia County’s building code sets wind speed zones ranging from 120 mph inland up to 140 mph and higher along the coast, and homes within one mile of the Gulf fall inside Florida’s wind-borne debris region. That triggers stricter product approval and, in most cases, a higher installed price than what you’d pay a few miles inland.
If your house sits on Perdido Key or near the bay, expect quotes on the higher end of any range you’re given.
What actually moves the price on a quote:
- Window opening size and shape (custom or arched openings cost more to manufacture)
- Frame material: vinyl is typically 15-30% cheaper than aluminum for the same size
- Glass upgrades like Low-E coating or insulated glass, which add $30-$120 per window
- How many windows go in at once, since permitting and mobilization costs get spread across the job
- Structural repairs if the existing frame or stucco has water damage, common in homes built before 1990
Brand matters too, and it’s worth knowing the names before you sit through a sales pitch. PGT and CGI are the two most commonly installed impact brands in this part of Florida, both manufactured in-state. Simonton and ES Windows (built by Tecnoglass) show up frequently in mid-range quotes.
None of these are objectively “better” across the board, the right pick depends on your wind zone, your budget, and whether you’re matching an existing product line for a partial replacement.
Here’s the part most quotes leave out: Florida Statute 627.0629 requires insurers to offer a wind mitigation discount once all openings are protected, and that discount can run several hundred to a few thousand dollars a year depending on your policy and coverage area.
The My Safe Florida Home program has also offered a 2:1 grant match up to $10,000 for qualifying wind-mitigation work, including impact windows, though funding availability changes year to year and it’s worth checking current status before you count on it.
A full house replacement, 15 to 20 openings, typically lands between $15,000 and $35,000 depending on tier and window count. That’s a wide range on purpose. Get a written, itemized quote before comparing anyone’s number to it.
