I heard a LOUD bang in the morning and went to the garage to see what happened. Garage door would not open. I called Halls and the tech told me the spring had probably broken. Sure enough. Just from the sound he knew what happened. He said he could come that morning. I had to go out so he repaired it without me there greased the other door to the garage and left the work area clean. He called to say work was done. WOW great service..
