You call, we ask where you are and what the door's doing - won't open, makes a noise, opener runs but the door doesn't move. For towns closer in, like Southwood Valley or Cedar Ridge, that's a short drive. For Hearne, Clay, or Snook, it's a longer one, so travel time factors into when we can get there, not whether we will.
Once we're on site, we look at the actual hardware rather than assume based on the neighborhood's build year. A moderate-heat climate like this one doesn't put much stress on doors from cold or ice, but it does mean springs and cables go through a lot of thermal cycling over the years - expansion and contraction that fatigues metal even without dramatic weather.
