The climate here is mild temperate, so we're not dealing with the freeze-thaw cycles that crack wood panels outright, but decades of dry heat and cool nights still cycle the wood, and that slow expansion and contraction is what throws torsion springs out of balance on houses built when this area was mostly framed in the 1960s. It's a different failure path than newer construction sees. A door built to a 2020s code, on 2020s steel, doesn't carry the same spring load or sag the way a 1963 wood panel door does after sixty years of that cycle. Income levels here run well above the region's median, which we mention only because it shows up in the choices owners make once we're in the driveway - more of them opt to replace an original door outright rather than nurse it along, once they see what a full rebuild would run. Either way is a fair call. We just want the diagnosis to be honest about which one you're actually facing before you decide.
