What Is Going On
Most of the calls we get start the same way: "it's making a noise and I don't know if that's normal." The honest answer depends a lot on when your house went up. A lot of what we work on in this area was built between 1967 and 2006, with the heaviest run through the 1980s and 90s. That matters because doors and openers installed in that window are now anywhere from 20 to 55 years old, and torsion spring hardware from that era wasn't built to last forever quietly.
A rhythmic thump once per rotation usually means a flat spot on a roller, or a roller that's worn down and riding unevenly in the track. A sharp metallic bang, once, is almost always a cable or spring letting go - don't touch the door after that sound, just stop using it. A steady grinding whine as the door travels is often the opener's gears wearing out, which tracks with age for units installed when a lot of this housing stock was new. None of these are mysterious once you know roughly how old the hardware behind the wall is.
The area
When to Call Someone
Call same-day for a loud bang followed by the door refusing to move, or moving unevenly on one side - that's a broken spring or snapped cable, and springs under tension are not a weekend project. Call soon, not urgently, for a grinding or screeching sound that's gradual and getting worse over weeks; that's wear, not failure, and you've got some runway.
Don't call anyone, and don't panic, for a single soft click at the very top or bottom of travel. That's usually just the opener's limit switch doing its job. The distinction that matters is sudden versus gradual. Sudden, loud, and the door stops working - that's urgent. Gradual, rhythmic, and the door still runs - that's maintenance, and it can wait for a scheduled visit instead of an emergency one.
What we find
The Common Mistake
The mistake we see most is spraying WD-40 on a grinding sound and calling it fixed. It quiets things down for a week, sometimes two, because WD-40 is a solvent, not a lubricant - it strips old grease rather than replacing it. On hardware that's already 20-plus years old, which describes a lot of the doors installed during the 1980s and 90s building run through here, that leaves bare metal grinding on bare metal once the solvent evaporates.
The second mistake is assuming a noise that showed up in winter will go away in spring. Sometimes it does, if it was just stiff grease. But if the underlying roller or bearing was already worn, cold weather just exposed a problem that was coming anyway. Treating the symptom instead of asking what changed is how a $20 roller job turns into a cable snapping six months later. We'll tell you plainly when a noise is cosmetic and when it isn't - we don't pad a service call.

How Local Conditions Play In
This area sits in a cold-moderate climate band, not the deep freeze further north, but enough winter cold that lithium grease on rollers and hinges stiffens up by January if it hasn't been serviced since fall. That stiffening is often what turns a quiet door into a noisy one with no other change - the metal didn't fail, the lubricant did.
Across the roughly 37,594 households in the service area, with 11,497 owner-occupied houses concentrated in that 1980s-2006 construction window, we see the same pattern repeat: original steel track and torsion hardware that was fine for two decades starts complaining the first hard cold snap after a worn part finally loses its margin. It's not dramatic weather causing the problem - it's ordinary seasonal cold meeting hardware that was already due. Carrboro, three miles off, sits on much of the same builder-grade stock from that era, so the same noises show up there for the same reasons.
