If your door is sagging at one corner, sticking halfway up, or the seams along the panel are starting to separate, that's steel fatigue typical of a door that's been through repeated Heat Moderate summer cycles without insulation backing - common on original 1987-era doors. If the opener strains audibly or the door reverses on its own partway through closing, that's very often a spring that's lost tension, not the opener itself, and it's worth a look before you commit to full replacement. A new install makes sense when the door itself - panels, hinges, rollers - is worn past adjustment, not just when one component is loud. We'll tell you plainly if a repair gets you another few years cheaper than a full swap; that call depends on what we find at the door, not on what's easiest to sell.
