How much does it cost to replace a broken torsion spring?

Replacing a broken torsion spring typically costs 200 to 400 dollars by a professional, with most homeowners paying around 250 to 350 dollars for both springs replaced together. Pricing breaks down as 50 to 100 dollars per spring for parts, 150 to 250 dollars in labor, and a standard service call fee. Even though usually only one spring breaks, technicians strongly recommend replacing both at the same time because they wear at the same rate, and the second is likely to fail within months. Heavier double doors, 8-foot-tall doors, or commercial doors run 400 to 700 dollars. Upgrading to high-cycle springs rated for 20,000 to 30,000 cycles adds about 75 to 150 dollars per spring but roughly doubles the lifespan.
