We don't have a fixed number to quote you here - every job depends on whether it's a spring swap, a full roller set, or something the door's track geometry is fighting us on. What we can tell you is that a broken torsion spring is usually a same-visit repair once we're on site with the right spring size, and a full door swap is a bigger job we'd walk you through before starting, not after. If a shop quotes you a price over the phone sight unseen for a Bokeelia job, be skeptical - the honest number comes after someone looks at the spring size, the track condition, and the opener.
