Hurricane force winds can turn landscaping materials into missiles that can break windows and doors. Replace gravel/rock landscaping materials with shredded bark and keep trees and shrubbery trimmed. Cut weak branches and trees that could fall on your house. 

Buy the materials you need to brace garage doors and windows. If you live in a mobile home make sure you know how to secure it against high winds. If you have a boat on a trailer, it too needs to be protected. Make sure you’ll be able to move it close to the house, fill it with water to weigh it down and lash it securely to the trailer. You’ll need to be able to anchor the trailer to the ground or house. 

Consider retrofitting your home against hurricane damage. This can be an expensive project, but you can do it in stages. Insurance companies may offer discounts for retrofitting which can help offset the cost. 

Protect windows and doors against breakage. Much of the property damage associated with hurricanes occurs after the windstorm when rain enters structures through broken windows, doors and openings in the roof. Install impact-resistant windows or hurricane shutters. 

Make certain doors have at least three hinges and a dead bolt security lock with a bolt at least one inch long. Since sliding glass patio doors are more vulnerable to wind damage than most other doors, consider installing impact-resistant doors made of laminated glass, plastic glazing or a combination of plastic and glass.
