The Bottom Line Up Front
Florida homeowners who install qualifying hurricane impact windows and doors can typically receive a windstorm insurance premium reduction of 15–45% on the windstorm portion of their homeowner's policy. This is enabled by Florida Statute §627.0629, which requires insurers to offer premium discounts for wind-resistant construction features.
To claim the discount, you need a licensed inspector to complete a wind-mitigation report (form OIR-B1-1802) after installation, which you then submit to your insurance carrier. The carrier applies the credits based on what the inspector documents.
Important: The exact discount amount varies significantly by insurer, policy, how much of the windstorm premium applies, and what percentage of your openings are protected. Always confirm with your specific carrier before committing to a project based on insurance savings.
How the Florida Wind-Mitigation Process Works
Install impact windows and/or doors
Work with a licensed contractor (like Anchor Windows & Doors) to install Florida Product Approval-rated impact windows, doors, or shutters. Keep all product documentation and permits.
Schedule a wind-mitigation inspection
After installation is complete, hire a licensed wind-mitigation inspector. They will inspect your home's storm-resistance features and document them on form OIR-B1-1802 (the standard Florida wind-mitigation inspector's report). Inspections typically cost $75–$150.
Submit the report to your insurer
Provide the completed OIR-B1-1802 to your homeowner's insurance carrier. They review the credits earned and adjust your premium accordingly. Contact your agent to initiate the process.
Receive your adjusted premium
Your carrier will apply the applicable discounts, typically effective at your next policy renewal or immediately depending on your carrier. Wind-mitigation reports are typically valid for 5 years.
What Qualifies for a Wind-Mitigation Credit?
The OIR-B1-1802 form documents several categories of wind-resistant features. For opening protection specifically, the inspector looks at your windows, doors, skylights, and other openings and classifies each as:
| Protection Type | Typical Credit Level |
|---|---|
| Impact-rated windows and doors (all openings) | Highest credit — typically the largest discount |
| Impact-rated windows and doors (partial) | Proportional credit based on % of openings protected |
| Hurricane shutters (accordion, roll-down) | Credit, though typically less than full impact |
| No protection (standard glass) | No credit for unprotected openings |
Credits vary by insurer. This table is illustrative, not a guarantee of any specific discount amount.
Is This Worth It in Sarasota and Bradenton?
Windstorm insurance is a significant expense for Sarasota County and Manatee County homeowners. If the windstorm portion of your annual premium is $3,000–$6,000 (common for homes in this area), a 30% discount would save $900–$1,800 per year. Over 10 years, that's $9,000–$18,000 in cumulative savings — which makes a meaningful dent in the cost of impact window installation.
Impact windows also eliminate the need for and labor of hurricane shutters, add resale value, reduce noise, block UV, and may reduce cooling costs — so the windstorm discount is often just one component of the ROI case.
Frequently Asked Questions
How much of a windstorm insurance discount can I get in Sarasota for impact windows?
The discount varies by insurer and policy, but is commonly cited in the range of 15–45% on the windstorm portion of your homeowner's insurance premium. The windstorm portion is not the total premium — but it's often a significant portion for Sarasota County and Manatee County homeowners. Confirm the specific amount with your insurance carrier before making your investment decision.
What is the wind-mitigation inspection for impact windows in Florida?
A wind-mitigation inspection is a professional assessment of your home's storm-resistance features, completed by a licensed inspector. The results are documented on form OIR-B1-1802 (or its equivalent). This form is submitted to your insurance carrier to claim credits for impact-rated openings, roof features, and other wind-resistant construction.
Do hurricane shutters also qualify for a wind-mitigation discount in Sarasota?
Yes — properly installed and documented storm shutters (accordion, roll-down, panel) are recognized as opening protection on the wind-mitigation inspection form. However, they generally provide a smaller discount than fully impact-rated windows and doors, and require action before every storm rather than providing permanent protection.
Do I need impact windows on every opening to get the insurance discount?
No — a partial opening protection can still earn a credit, though the discount is typically larger when all openings are protected. The inspector documents the protection level of each opening type. Your carrier applies discount credits based on the percentage and type of protected openings.
