How We Fix It
Weston's housing stock centers on 1964, which puts most garage doors here squarely in the extension-spring era rather than the torsion-spring era that took over in the 1970s. That matters for cable work because extension-spring doors route the lift cable over a pulley at the top of each track, down to the spring on a stationary pulley at the back. When that cable frays or jumps the pulley, the door usually drops crooked on one side before it binds completely. We pull the old cable off the drum or pulley fitting, check the pulley itself for a worn groove (a common failure on doors this age), and run a new galvanized cable sized to the track length. We test the door through a full cycle before we leave, because a cable that looks fine on a slow hand-pull can still catch under motor speed. We come from our Waltham shop, four miles off, so there's a short drive built into any visit here, not a dispatch from a local branch.
Stocked Parts
We carry standard-gauge lift cable and the common pulley sizes that fit the extension-spring hardware found on doors built through the 1960s and into the 1970s, which covers the bulk of what's on the road and in driveways in this part of the service area. If a door has a less common drum fitting or a pulley bracket that's been welded or modified over the years, we may need to source that part rather than pull it off the truck, and we'll tell you that up front rather than guess at a fix. We don't stock torsion-spring cable drums as heavily, since that hardware is less common on homes built before the mid-1970s.
How Long It Takes
A straightforward cable swap on an extension-spring door, once we're on site, usually runs under an hour - pull the old cable, check the pulleys and drum, run the new cable, cycle the door a few times under load. Add time if both cables need replacing, which is common since they wear at close to the same rate and most owners wait until one fully snaps before calling. Add more time if the pulley groove is worn enough that it needs replacing too, or if the door has been riding on a damaged cable long enough that the track has shifted out of alignment. We quote the job once we've looked at the actual hardware, not before.
