Yes. In Florida, impact windows can lower the windstorm portion of your homeowners insurance through what the state calls wind mitigation credits. The savings are not a gimmick and they are not automatic either. You have to install approved products, permit the work, and file a wind mitigation inspection with your insurer. This guide explains how the credits work, how much you might save, and the steps to claim them.
Why Florida gives you a discount
A large share of a Florida homeowners premium covers windstorm risk. When you harden your home against that risk, you file fewer and smaller claims, so state law requires insurers to pass part of that reduced risk back to you. Impact windows are one of the strongest features you can add, because they protect the openings that fail first in a storm. Cover every opening and you remove one of the biggest ways wind and debris get inside.
How much can you actually save?
This is where honesty matters. The credit depends on your insurer, your county, your home’s construction, and how much of your premium is tied to windstorm coverage. Homes in high-risk coastal areas carry a larger windstorm share, so they tend to see bigger dollar savings. We will not promise a specific percentage, because the number is different for every home. What we can say is that the credit recurs every year for as long as the windows are in place, so even a moderate annual savings compounds into real money over a decade.
Key point: The discount applies to the windstorm portion of your premium, not the whole policy. In coastal South Florida, that portion is often large, which is why impact windows can move the needle more here than in inland states.
The catch: you have to cover every opening
To earn the full opening protection credit, every window, door, and skylight has to be impact rated or protected. If you replace most of your windows but leave one old slider or an unprotected garage entry, the home may not qualify for the top credit, because a single weak opening still lets wind pressurize the house. This is one reason we recommend doing the whole home at once, and it is where financing helps, since it lets you protect everything now rather than in stages.
How to claim your discount, step by step
- Install approved impact products. They must carry the ratings your county requires, with Notice of Acceptance approval in Miami-Dade and Broward.
- Permit and inspect the work. The job needs a permit and a passed final inspection. Unpermitted windows may not count and can cause problems at resale.
- Get a wind mitigation inspection. A licensed inspector completes the state form (often called the OIR-B1-1802) that documents your openings and roof features.
- Submit the form to your insurer. Your insurer applies the credits to your policy. Keep a copy for renewals and for the next owner if you sell.
Reputable installers handle the permitting and can point you to a qualified wind mitigation inspector. If your quote skips permits, that is a red flag for both your safety and your discount.
Insurance is only part of the payback
The insurance credit is one of several ways impact windows earn their cost back. You also get lower energy bills from low-E glass, a quieter home, and higher resale value. Stacked together, these returns recover a real portion of the price over time. We break down the whole picture in are impact windows worth it, and the pricing in our Florida cost guide.
Impact windows vs. shutters for insurance
Approved shutters can earn some wind mitigation credits too, but impact windows usually qualify for stronger credits because they protect every opening at all times with nothing to deploy. If you are weighing the two, our comparison of impact windows vs. hurricane shutters lays out the trade-offs on cost and protection.
The bottom line
Impact windows lower your insurance in Florida, but the savings come with steps: approved products, permits, a wind mitigation inspection, and full opening coverage to earn the biggest credit. Do it right and the discount rewards you every year, on top of the energy, comfort, and resale benefits. Browse the lines we install on our impact windows and impact doors pages.

Frequently asked questions
Do impact windows lower your homeowners insurance in Florida?
Yes. They can qualify you for wind mitigation credits on the windstorm portion of your premium, as long as the products are approved, permitted, and documented with a wind mitigation inspection.
How much do you save on insurance with impact windows?
It varies by insurer, county, and home. Coastal homes with a larger windstorm premium tend to save more. The credit recurs every year the windows are in place.
Do I need to replace every window to get the discount?
To earn the full opening protection credit, every window, door, and skylight must be impact rated or protected. One unprotected opening can disqualify the home from the top credit.
What paperwork do I need to claim the credit?
You need permitted, inspected installation and a wind mitigation inspection form (often the OIR-B1-1802) submitted to your insurer, who then applies the credits.
Do shutters give the same insurance discount as impact windows?
Approved shutters can earn some credits, but impact windows usually qualify for stronger credits because they protect every opening at all times.
