How much you should pay to have a garage door spring replaced depends on type of spring, door size, and labor, but typical costs provide fair pricing guidance. For torsion springs that mount above door and are most common, professional replacement of single torsion spring costs 200 to 400 dollars including parts and labor, while pair of torsion springs costs 300 to 600 dollars including labor, as most professionals recommend replacing both springs at same time since they have same age and cycles and second will break soon after first, saving service call fee later. Extension springs that run along sides of door cost less, with pair costing 150 to 350 dollars professionally replaced. Cost breakdown includes spring itself costing 50 to 150 dollars per spring and labor costing 100 to 200 dollars, with service call fee of 75 to 150 dollars often included. Factors that increase cost include large or heavy wood door requiring larger springs, high-cycle springs rated for 20,000 cycles costing more, emergency or after-hours service adding 50 to 100 dollars, and difficult installation requiring more time. DIY spring replacement is not recommended due to high tension danger that can cause severe injury, as torsion springs store energy and require special tools like winding bars. Getting multiple written estimates from reputable garage door companies ensures you pay fair price and that springs are correctly sized for door weight and balance. Properly replaced springs last 7 to 12 years or 10,000 cycles.
