How to Protect a Garage Door from Storm Damage

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.

  1. Hello Ben,
    Thanks for the prompt response and the pictures !
    I had new garage doors installed a few months ago and have put off reinforcment preparations until today, when the weatherman forecasted hurricane Irene was going to pay us a visit this weekend.
    I am planning on using some 4 inch wide metal to attach the braces to the header . Other than that, I will follow your instructions. I will send pictures when completed tomorrow, if you are interested.
    Thanks again for the immediate response.
