How We Fix It
First we check whether the track itself is bent or just unbolted, because those are two different jobs. On a lot of these 1957-era garages the fix is re-securing the track brackets into solid framing, since the original mounting points have often worn oversized from decades of vibration. If the track is bent, it gets replaced rather than hammered back into shape - a track that's been bent once is weaker at that point permanently, even if it looks straight afterward. We check the rollers next, since worn or cracked rollers are what let a door wander off a track that's otherwise sound. On extension-spring systems specific to this housing era, we also check that both springs are matched and carrying even tension, because one weak spring pulling harder than the other is a common reason these older doors walk off-track on one side over time. We don't force a bent track back into service to save a trip charge - that's the kind of shortcut that puts you back where you started in a few weeks.
The Cost of This Job
We don't have a fixed number to quote here without seeing the door, since the range between rebolting a loose bracket and replacing a bent track section plus rollers is wide. What we can say is that Compton's median household income runs $74,270, noticeably below the $83,538 median across the wider service area, and we take that into account when we talk through repair versus replace options rather than defaulting to a full system swap. On the older extension-spring hardware common to this town's housing stock, track and roller repairs are usually the more affordable path unless the door itself is warped or the springs are original and due anyway.
How It Shows Up
On these older two-track systems, the first sign is usually a door that shudders or catches at the same spot every time it opens, right before one side dips visibly lower than the other. Sometimes it's quieter than that - a gap opens up between the roller and the track that you can only really see from underneath the door with it half open. If a cable has come off a drum on one of these extension-spring setups, the door will hang crooked at rest, tilted toward whichever side let go. None of these are safe to force through with the opener; running the motor against a door that's already off-track usually bends the track further or pulls the opener's drive gear, turning a bracket repair into a bigger bill.
