How much does it normally cost to replace springs on a garage door?

The cost to replace garage door springs typically ranges from $150 to $350, encompassing both the cost of the parts and the professional labor required for the safe installation. If you have a lighter, single-car garage door that utilizes extension springs (which stretch along the sides of the horizontal tracks), the replacement cost is generally on the lower end, averaging between $150 and $200. However, most modern or double-car garage doors use a torsion spring system (mounted on a metal shaft directly above the door opening). Replacing torsion springs is more complex, dangerous, and requires heavier-duty parts, pushing the average cost to between $200 and $350. It is a strict industry best practice to replace both springs simultaneously, even if only one has snapped. Because both springs have endured the exact same number of lift cycles and physical wear, the unbroken spring is almost guaranteed to fail shortly after the first one, making a dual replacement the most sensible, cost-effective long-term decision.
