A spring swap or opener repair on a door of this era usually takes less time than the same job on an older door, mostly because the hardware is in better shape to begin with and there's less improvisation needed to make old and new parts work together. The bigger variable is the trip. At 18 miles out, travel time from Aurora is part of the job, and we build that into the window we give you rather than pretending it isn't there. With roughly 4,523 households in Castle Pines compared to 107,476 across the whole service area, this isn't a town where we're already down the block on another call, so appointment windows here tend to be scheduled rather than same-hour.
