Somehow the safety cable got wrapped around the opener cable and I had a door that wouldn't go down. Called Davis and someone was at the house within two hours! Matt fixed the problem; no parts needed. He also tightened what was loose and lubricated the moving parts. I shared a story about the last garage door company charging me $400 for a repair. He was gobsmacked, then he told me a whole new door would have cost $480. My turn to be gobsmacked. The moral of the story: other guys will rob you. Davis Doors treats you right. Call them first!
