We don't have a fixed number to quote here without seeing the door - cable length, drum size, and whether anything else got damaged when the cable let go all move the price. What we can say is that a straight cable swap, no secondary damage, is a smaller job than a full spring and cable replacement, and we'll tell you which one you're actually facing before any work starts. Given that Union's median household income runs well above the service area's $80,814 average, cost usually isn't the deciding factor for homeowners here - the bigger question is usually how fast the door can be back in service. We price the job after we've looked at it, not before.
