Well, it appears from other reveiws that broken springs are a common problem. I called Covenant Garage Doors from the recommendation of a neighbor. When he came out, He politely introduced himself, assesssed my garage door, gave me a price for the srpings. He also noted that the cables were frayed and suggested I replace them as well. He did the work, also gave me a set of rollers for no additional charge (nice surprise!), cleaned up and now the door works great. I am glad I listened to my neighbor and called them.
