Barton Creek sits about 7 miles from where the truck starts its day, so the honest answer is: it depends on where the call falls in the route, not on a fixed number we can promise in writing. What we can tell you is that a house built around 2002, which is the median year for this area, almost never needs a special-order part. The steel sections, torsion springs, and openers common to that build era are still in normal production, so once the truck arrives the fix itself is usually quick - it's the drive time that adds the variable, not the parts hunt. Older stock elsewhere in the region sometimes needs a day or two for an odd-width spring or a discontinued track bracket. That's not the situation here. With roughly 1,438 households in this pocket, most doors are close enough in age and spec that one van stocked for a 1990s-through-2010s range covers nearly everything we're likely to find on a given call.
