Sanford is four miles from Lake Mary, a short drive that doesn't add meaningfully to the job itself. The repair time depends on what actually failed. A roller that's simply jumped the track and a bracket that needs a half-turn of the wrench is a short job - realign the section, reseat the roller, check the door through a few full cycles. A bent section of track or a bracket that's pulled loose from the framing takes longer, since the track has to come off, get straightened or swapped, and get re-shimmed level before the door runs clean again. We won't promise a number up front over the phone - door weight, how long the track has been out of alignment, and whether the opener's force setting has been fighting the problem all change the actual time on site.
