How much does it cost to replace windows in Florida?
Replacing windows in Florida runs $400 to $1,200 per impact window installed on HomeGuide's published figures, because the code drives the product choice.
The important thing about Florida is not a different price list. It is that the cheap window on a national price list is often not a window you are allowed to fit, so the comparison a Florida homeowner needs is between storm-rated products rather than between ordinary ones.
Nobody publishes a Florida price, and we are not going to invent one
There is no published state multiplier for windows. The bands on this page are national ones from a named guide, and the Florida-specific parts of the answer below are code, programme and law — things that genuinely are different here, and that are published.
The published bands
| Window | Published cost per window installed |
|---|---|
| Hurricane (impact) window | $400 – $1,200 |
| Storm window fitted over an existing one | $150 – $400 |
| Single-hung | $300 – $2,100 |
| Double-hung | $350 – $2,500 |
| Sliding | $300 – $2,300 |
| All windows, average range | $450 – $1,500 |

HomeGuide also prices a whole house of impact windows at $6,000 to $24,000 for the 10 to 15 windows it calls an average home, labour at $100 to $500 per window, and hurricane windows alone, before fitting, at $300 to $800. Its storm-protection guide gives a second reading for the same product at $40 to $70 per square foot. The two do not agree and both are printed.

A storm window is not an impact window
HomeGuide prices storm windows at $150 to $400 each installed and says plainly that, unlike impact windows, they do not protect against flying debris or hurricane-force winds. They are a second pane fitted over the existing window for noise and insulation. The names are close enough that quotes get compared as though they were the same product. They are not.

What Florida adds that other states do not
My Safe Florida Home offers a free wind mitigation inspection and grants of up to $10,000, and lists impact windows and doors among the approved upgrades. Separately, Florida Statutes section 627.0629 requires residential property insurance rate filings to include discounts for construction that reduces windstorm loss, naming opening protection and window strength, and since October 1, 2023 requires insurers to describe their hurricane mitigation discounts on their website. Neither the statute nor the programme publishes a discount percentage, so ask your carrier for its own figure.

The approval number is the thing to check
HomeGuide names the standards a storm-rated product is tested to: the Florida Building Code, Miami-Dade TAS 201, 202 and 203 for the High-Velocity Hurricane Zone, ASTM E 1886 and E 1996, and AAMA 506. It warns that inside the High-Velocity Hurricane Zone, ASTM testing on its own is not sufficient. Ask for the approval number of the exact unit being quoted, in writing, before any money changes hands.

Questions people ask next
- Does Florida pay for impact windows?
- Partly, for homeowners who qualify. My Safe Florida Home offers a free wind mitigation inspection and grants of up to $10,000, with impact windows and doors listed among the approved upgrades. The inspection comes first, then the grant application.
- How much does it cost to replace all the windows in a Florida house?
- On HomeGuide's published figures, $6,000 to $24,000 for a house of 10 to 15 impact windows. A house with large openings or sliding glass doors runs above that, and the same guide's per-square-foot band is the better check in that case.
- Is there a difference between hurricane windows and impact windows?
- In everyday use they are the same product, and HomeGuide's cost table lists them under one heading. What matters is not the word on the quote but the product approval number, which is what tells you the unit was tested to the standard your county enforces.
