Garage door springs, also known as torsion springs, are the most common form of garage door repairs. Often the main spring for the garage will brake into two pieces and make a very loud 'bang' sound.  At Supreme Garage Door Repair we recommend that only a professional perform this repair. The garage door spring holds a lot of pressure that can easily injure or severely harm the person who is trying to repair it. You should always have a trained professional come out and perform the job properly.
