"The big heavy sliding gate in the driveway decided to freak out. It came off the tracks and weighs over 500 pounds. Alpha Security Group is my hero! The team immediately found the issue, fixed it, and welded a stopper on the gate so it wouldn't happen again. Prompt response, friendly, courteous, and they have a great understanding of how to make old gate openers work again!"
