Most calls start the same way: the door hesitates halfway up, or it slams down the last foot instead of settling. On a torsion-spring setup, that's usually a spring losing tension after years of cycles, and a lot of the doors we open up in Delray Beach are original to houses built between 1965 and 2005, with the bulk of that stock going up in the 1960s and '70s. Original hardware on a house that old has usually seen one or two spring replacements already, sometimes with parts that don't match the door's weight.\n\nYou'll also hear it before you see it - a grinding or popping sound from the tracks, or an opener that runs longer than it used to before the door actually moves. That's the motor working harder to compensate for a spring that isn't doing its share of the lifting anymore. On some of the older single-layer steel doors common in the 1960s-70s tracts across the area, the panels themselves are fine, it's the spring and roller hardware underneath that's given out. A door that's suddenly noisy, slow, or uneven side to side is telling you the spring and track system, not the panel, is the problem.
