The area sits in a cold, severe winter climate band, and that affects torsion springs and steel track the same way it affects any metal that contracts in the cold: springs lose a little tension, tracks can bind, and a door that worked fine in October sometimes needs a hard shove by January. On 1990s-era doors like most of what's in Douglas, this usually shows up as a slow or uneven close rather than a dead door, because the hardware is newer and better sealed than older stock.
The other complication is simpler: distance. At 10 miles out, Douglas is farther from our shop than some of the other towns we cover - Beechwood, for instance, sits at 2 miles - so a same-day call to Douglas gets scheduled into a route rather than squeezed in on the way past. That's not a promise about speed, just an honest note on how routing works when you're not the closest stop.
