Our tornado storm shelters are FEMA approved and tested at Texas Tech University to withstand F5 tornadoes and up to 250 mph winds. After you contact us to let us know you've chosen a shelter, we will schedule a date & time for installation. Our installers are fantastic!! Very friendly, quick, and clean! Our shelters come with a Geo Tracker service that notifies you after a tornado has been spotted near your location to make sure you are safe. You can call, text, email or msg us anytime.
