A straightforward spring or cable repair on a standard single or double door is usually a same-visit job once we're on site - we carry the common torsion spring sizes that match this housing era, since we see them so often. Where it slows down is parts that aren't common: an opener model that's been discontinued, or a track width that doesn't match current stock. In those cases we're ordering in, and that can run from a couple of days to a couple of weeks depending on the manufacturer. We're honest about that timeline up front rather than guessing optimistic and missing it. Since we run out of New Haven, about four miles away, travel time isn't the bottleneck - it's almost always the part, not the drive.
