Torsion spring replacement on single and double doors is the most common call we get from Highland, usually tied to the age of the door rather than any one failure event. Second most common: opener logic boards and circuit failures on units that have been cycling through severe summer heat for a couple decades without being swapped. We also replace worn rollers and reset off-track doors more in Highland than in newer-built areas, which lines up with the 1982 median build year. One limitation worth saying plainly: if a door's torsion tube or jamb bracket has been bent as part of the spring failure, patching the spring alone won't hold - that's a case where we tell you straight that replacement hardware, not just a new spring, is the honest fix.
