What the Weather Here Does to It
Gastonia sits in a cold-moderate climate band, which means the ground freezes and thaws more than once a season instead of staying locked one way all winter. That back-and-forth moves concrete. A garage slab that heaves even a quarter inch at one corner twists the track bolted to the framing above it, and the door starts riding the rollers against one side of the track instead of straight down the middle. You'll hear it before you see it - a grinding or a tick on the way up that wasn't there last spring. This isn't a one-time event. It's a repeating cycle tied to how many freeze-thaw swings a given winter brings, and some winters bring more than others. Houses with the garage slab poured separately from the foundation (common in this area) move independently of the house itself, which is exactly the setup that walks a track out of alignment over a few seasons. None of this is dramatic. It's slow, and that's what makes people ignore it until the door binds hard enough to stall the opener or pop a roller off the rail entirely.
The Situation
Housing across the Gastonia service area was mostly built between 1967 and 2011, with the thickest cluster going up in the 1980s and 90s, spread across the 17 named areas we work in. That matters for track problems specifically because the garage framing methods and track hardware from that build window weren't engineered for decades of slab movement - they were engineered to pass inspection once. A door track mounted to a 1980s stud wall with the fasteners of that era doesn't have the same holding power as something installed last year, and after 30-plus years of seasonal shift, the anchor points loosen before the track itself fails. With roughly 20,806 owner-occupied houses in the broader service area, most of them land in this same build window, which is why track misalignment shows up as a pattern here rather than a random one-off. It's rarely the track that's defective. It's the wall it's screwed into, and the slab under that wall, that have both moved a little more than the hardware was built to tolerate.
What to Look At First
Start at the bottom corners of the slab, not at the door. If you can see a gap or a lip where the slab meets the driveway apron, that corner has likely shifted, and that's usually the side where the track binds first. Next, check whether the vertical track is still plumb against the wall - a level held against it will show a lean most people can feel with a hand before they see it. Look at the lag screws holding the track brackets to the jamb; in houses from the 1980s and 90s stock common here, those are often still the original fasteners, and they back out slightly as the wood around them compresses over the years. Finally, run the door by hand with the opener disconnected and feel for the exact point where it drags - that's your misalignment point, not the whole track. Fixing the one spot that binds is a different job, and a cheaper one, than replacing a track that's actually fine everywhere else.
