What is the average cost to replace two springs on a garage door?

The average cost to replace two springs on a garage door, which is recommended when you have two torsion springs and one breaks, depends on spring type, door size, and labor, but typical costs help budgeting. On average, replacing two torsion springs professionally costs 300 to 600 dollars total, including parts and labor, with single torsion spring replacement costing 200 to 400 dollars, so pair costs more but saves future service call as second spring likely near end of life with same cycles. Cost breakdown includes two torsion springs costing 50 to 100 dollars each for standard 10,000 cycle springs, or 100 to 150 dollars each for high cycle 20,000 cycle springs that last longer, plus labor of 150 to 300 dollars for professional installation that includes winding springs with proper tension and balancing door. Extension springs that run along tracks are cheaper, with pair replacement costing 150 to 350 dollars professionally, as springs cost 20 to 40 dollars pair and labor less but still requires safety cables. Factors increasing cost include larger double garage door requiring larger springs, high cycle springs, emergency or same-day service adding 50 to 100 dollars, and additional repairs like cable replacement. DIY replacement is not recommended due to high tension danger, but if attempted, springs cost 50 to 200 dollars pair plus winding bars costing 20 to 40 dollars. Getting multiple estimates from reputable garage door companies ensures fair pricing and proper sizing based on door weight.
