Garage door repairs cost between $150 to $350 on average. But this depends on the type of repair and the extent of the damage, and repairs can range from $100 to $800. Broken garage door springs, chains, cables, rollers replacement, sensor repairs and realignments, track realignments and repairs, and dent repairs are on the lower end, ranging from $100 to $300. On the other hand, door panel replacements can be on the higher end, costing around $500.
