After reading reviews on Kudzu.com, I chose Covenant Garage Doors. Mace arrived at the scheduled time and explained how long it would take to replace the broken spring. In addition to replacing the springs, he tightened all garage bolts, checked the rollers, lubricated the rollers and springs with silicon spray, checked the track, checked the overhead lifter and the pulley cables. His warranty is longer than his competitors. Highly recommend and if needed I will use Covenant Garage Doors again.
