Cable Repair for Litchfield's 1980s Garage Doors

What You Pay

Litchfield's housing mostly went up around 1986, which means the garage doors on most driveways here are steel sectional units - a 16-foot double or a 9-foot single, hung on galvanized aviation cable instead of anything fancier. That's the door we're quoting when a cable job comes up. A single frayed or snapped lift cable on a one-car door costs less than a matched pair on a 16-foot double, since a double carries two cables working together and both usually get replaced at once even if only one let go - mismatched wear on the second cable is a callback waiting to happen. We don't post a flat number here because a slipped cable that's still on the drum is a different job from one that's jumped the track and bent a roller bracket on the way down. We'll give you the number on-site before we touch anything, not after.

What the Fix Involves

On a door this age, the cable usually runs 1/8-inch or 3/32-inch 7x19 galvanized aircraft cable from the bottom bracket up to the drum on the torsion shaft, or on older extension-spring setups, over a pulley at the top corner. We release spring tension first - this is not a step to skip or improvise, and it's the part that hurts people who try it themselves. Then we pull the old cable, check the drum grooves and bottom bracket for wear, and re-string with new cable sized to match the original. If the bottom bracket itself is bent or the roller's seized in its track from age, we replace those parts too rather than lace new cable through hardware that's already failing. We test the balance by hand afterward, not just by running the opener, because a door that's out of balance will eat the next cable just as fast as it ate this one.

What Causes It Around Here

Litchfield sits in a cold, severe climate band, and that matters more for cable than most homeowners expect. Cable itself doesn't care much about temperature, but the galvanized coating on older runs - the kind common on doors built around 1986 - wears thin faster when the door cycles through repeated freeze-thaw swings over 35-plus years, and a thin or rusted strand frays instead of breaking clean. The other driver is simple mileage: a door built when Reagan was in office has had three or four decades of openings and closings, and cable is a wear item even on a door that's never had any other problem. We also see cables that jump the drum groove after a spring loses tension gradually - the cable looks fine until it's suddenly not, because it's been riding off-track for months.

What Can Go Wrong

A cable that's frayed but not yet broken will sometimes still lift the door, which tricks people into waiting. Don't - a cable under load that's shedding strands can let go without warning, and a door coming down uncontrolled on a double-wide span is a lot of falling steel. If a cable snaps while the door's open, the opposite side usually can't hold the weight alone, and the door drops hard, often bending the track or the bottom panel on the way. We've also found that a cable job called in as
