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.
How long does impact window installation take?
1-3 days of installation, 3-8 weeks including product lead time and permitting. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are number and size of openings; design pressure rating required for your wind zone; aluminum versus vinyl frames.
