Garage door spring formula
Total cost = count × (spring price + labor)The cost includes the spring (torsion above the door or extension along the tracks) plus labor: installation, tensioning and balancing the door.

1 × ($150 spring + $150 labor) = $300.
FAQ
Frequently asked questions
Torsion or extension?
Torsion springs mount above the door, last longer and are safer; extension springs run along the tracks and are cheaper. Converting costs $400-$800.
Why replace both?
Springs on the same door wear together — replacing one leaves the other ready to snap. Most pros replace the pair.
How long does it take?
A standard replacement takes 1-2 hours. The tech must re-balance the door after installation.
