The entry door is often the weakest opening in an older Fort Lauderdale house. If it fails in a storm, wind pressure gets inside and starts working on the roof. An impact door closes that gap, and it usually seals out water and street noise far better than the door it replaces.
Where your home sits changes the job. Simple exact replacements on houses, duplexes, and townhouses can use the city's Walk-Thru review. In the historic districts a new door needs a Certificate of Appropriateness. Near the beach, the city's flood maps include VE zones that face wave action, which affects ground-floor door choices. We check all three before ordering.
