A door built around 1997 is old enough now that its original torsion spring is near or past the end of a normal cycle life, even if it looks fine from the driveway. That's the main driver of maintenance calls in this part of the service area - not storm damage, not a hit from a car, just a spring that's quietly worn down after two and a half decades of daily cycles. Moderate heat is the climate factor that matters most here; it doesn't crack panels the way freeze-thaw does further north, but it does dry out lubrication faster and makes nylon rollers brittle sooner than a shaded, cooler garage would. Combine an aging spring with dried-out rollers and a track that's never been cleaned, and you get the slow, grinding start-up most owners describe as 'it's just gotten loud.' We travel the 13 miles out from Sugar Land for exactly this kind of call - not an emergency, just a door that's telling you it's due.
