Frequently asked questions
Do I need a permit to replace a front door in Florida?
Most Florida jurisdictions require a permit when the door frame is replaced, because the opening's wind-borne debris protection changes. A slab-only swap in the existing frame is sometimes exempt — confirm with your building department.
How long does exterior door replacement take?
Half a day to one day of work, 2-5 weeks with permitting. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are door material: steel, fiberglass or wood; impact rating and glass area; whether the frame and threshold are replaced.
