Frequently asked questions
Do I need a permit to replace windows in Florida?
Yes. Window replacement is a permitted alteration statewide because the opening protection and attachment must meet the wind-load requirements of the Florida Building Code. Product approval numbers are submitted with the application.
Are impact windows worth it in Florida?
Impact windows typically cost 40-70% more than standard units but can replace shutters entirely and often qualify for a wind mitigation insurance credit. In HVHZ counties, opening protection is required, so the practical choice is impact glass or approved shutters.
