The Cost of This Job
Most houses in Carnuel were built around 1975, which puts the neighborhood right in the middle of the 1968-1999 building window we see across this service area. That era matters for cable repair specifically: doors from the mid-1970s were almost always installed with galvanized aircraft cable on a standard drum-and-torsion setup, not the newer nylon-coated cable or the extension-spring track systems that show up in houses built after the late 1980s. That's good news for cost. Original torsion hardware on a 1975 door is straightforward to work on - the cable sizing is standard, the drums aren't proprietary, and we're not hunting down a part that only fits one builder's system. The job is a cable swap, a check of the drum for grooving, and a balance test on the spring, not a full teardown. Where cost climbs is if the drum itself is worn from decades of the old cable riding in the same groove, or if both cables need replacing because they're the same age and one going usually means the other isn't far behind.
What the Fix Involves
We pull the door down under control, release tension off the torsion spring so nothing is loaded while we work, and pull the old cable off the drum. On a house this age, that drum has usually never been touched, so we check it for wear grooves before running new cable through it - a cable running in a chewed-up groove will just fray again in a year. New cable gets seated, tension goes back on the spring, and we run the door a dozen times watching the drums turn evenly on both sides. An uneven cable length is the single most common comeback on this job, and it's avoidable if it's set right the first time. Carnuel sits in the same cold-moderate winter band as the rest of the area, and cold snaps stiffen old cable and make a marginal one snap instead of just fraying further - worth knowing if yours has been squeaking before it broke. One honest limit: if the drum is gouged badly enough that new cable won't sit true, we're not going to sell you a cable-only fix that fails again in six months - that's a drum job, not a cable job.
