Before you call anyone, look at three things. First, the panels - hairline cracks or rust-through on steel, or soft, delaminating spots on wood, mean the door's structure is failing, not just a part. Second, the track - if it's bent rather than just dirty, straightening it is often false economy on a door this old. Third, the springs - if nobody's touched them in years and the door feels heavy to lift by hand with the opener disconnected, that's wear, not a fluke.
Given Pasadena's mild climate, rust and warping are less common here than in wetter or colder regions, so if you're seeing heavy corrosion or wood rot on a door in this area, it usually points to a specific problem - a leak, irrigation spray hitting the door, or deferred maintenance - rather than the climate doing it on its own.
One limitation worth saying plainly: we don't recommend patching a door where the springs, tracks, and panels are all original and all near end of life at once. At that point, replacement usually costs less over five years than repair after repair.
