Frequently asked questions
Do impact windows need a permit in Florida?
Yes. Replacing a window changes an opening protection assembly, so every Florida jurisdiction requires a permit with product approval numbers and attachment details for each unit.
Do impact windows lower insurance?
Florida requires insurers to offer wind mitigation discounts for approved opening protection. Have a wind mitigation inspection done after installation so the credit is applied.
