Princeton is an eleven-mile drive from our Allen shop, farther than the four-mile runs to Fairview or Parker and closer than the trip out past Melissa. That drive doesn't change how long the spring swap itself takes once the truck is in the driveway, but it does change how we build the day. We schedule Princeton calls in blocks rather than squeezing one in between two Allen jobs, because backtracking on that road wastes more time than it saves. If you call and we're already routed toward Princeton, or have another job nearby, you'll hear that upfront. If not, you're looking at the next available slot on the schedule, not a same-day guarantee - we're honest about that distance rather than promising a response time we can't back up from eleven miles away. Once the tech is there, a straightforward torsion spring replacement on a double door runs about the same regardless of which side of the county line the house sits on. The drive affects when we can get there, not what happens once we do.
