Garage doors can be easily damaged by high winds during a hurricane or severe storm. Metal reinforcement kits are available that attach to the concrete slab and framing above the door to provide two additional points of support, or you can make your own garage door reinforcement from 2x4s.
To make your own garage door reinforcement, start by attaching a 2×4 to the concrete floor inside the door using lead shields or concrete screws.
Next, make two sturdy braces from 2x4s by attaching them together into a “T” shape. Extend the 2×4 on the brace that faces the outside of the garage 1½” to allow for attachment to the floor plate.
Make two support brackets from 2x4s and attach them to the framing above the door.
Secure the braces to the brackets above the door using bolts.
Secure the braces to the 2×4 plates on the floor with screws from the outside of the brace into the floor plate.
Unplug the garage door operator to prevent the door from accidentally opening while the braces are in place.
