The Short Answer
Installing impact windows and doors on your Florida home can reduce your wind insurance premium by 20–40%, depending on your home's location, construction, and your insurance carrier. For many Southwest Florida homeowners, this translates to $300 to $3,500+ in annual savings.
Over the 20–30 year lifespan of impact windows, those annual savings can total $6,000 to $100,000+ — often offsetting a significant portion of the installation cost.
How Florida Wind
Mitigation Credits Work
Florida law requires insurance companies to offer premium discounts for hurricane-resistant construction features. The mechanism for documenting these features is the Uniform Mitigation Verification Inspection Form (OIR-B1-1802), commonly called a wind mitigation inspection.
After your impact windows and doors are installed, a qualified inspector completes this form, documenting your home's hurricane-resistant features. Your insurance company uses this form to calculate your premium credits.
The wind mitigation form evaluates six key attributes of your home: roof coverings, roof shape, roof-to-wall connections, roof deck attachment, secondary water resistance, and opening protection. Impact windows and doors fall under Opening Protection — one of the most heavily weighted factors in the credit calculation.

Factors That Affect
Your Savings
Your Wind Zone
Coastal and barrier island homes see larger dollar savings because their base premiums are higher.
Miami-Dade NOA vs. Florida Product Approval
Some insurance carriers offer larger credits for products with Miami-Dade Notice of Acceptance certification.
Your Insurance Carrier
Different companies calculate wind mitigation credits differently. Shopping your renewal after installation often reveals significant differences between carriers.
Other Mitigation Features
A hip roof, strong roof-to-wall connections, and secondary water resistance multiply your total credit. The more mitigation features your home has, the larger your combined discount.
Your Deductible
Some policies offer reduced hurricane deductibles with documented mitigation features — an additional savings layer beyond the premium discount.
How to Claim
Your Savings
Install impact windows and doors with a licensed contractor
Keep all documentation — product approval numbers, permit records, and installation invoices. Your contractor should provide a complete package.
Schedule a wind mitigation inspection
Typically $75–$150, and the resulting OIR-B1-1802 form is valid for 5 years. Your inspector will document every mitigation feature on your home.
Submit the completed form to your insurance company
Your carrier is required by Florida law to apply the appropriate credits. Processing typically takes 1–2 billing cycles.
Shop your renewal
Once credits are documented on your form, compare quotes from multiple carriers. The same mitigation features can produce very different premium results across insurance companies.
