Doing It Yourself
A garage door cable looks like a simple fix
A length of braided wire running over a drum or pulley - but it's under real tension even when the door is down. On an extension-spring system, which is what you'll find on a lot of Kenner garages, the spring itself is stretched and ready to let go the second the cable it's attached to gives way. People get hurt loosening the wrong bolt on these.
We'll say plainly: this isn't a weekend project
You can inspect your own cable - look for rust-colored streaks on the drum, frayed strands near the bottom bracket, or a door that sits crooked when it's down - but replacing it means releasing spring tension safely first, and that's where most DIY attempts go wrong. If you've got the tools and you've done it before on a torsion system, fine. If you're not sure which system you have, that uncertainty alone is the reason to call someone out rather than guess.
How It Shows Up
The most common sign is a door that hangs unevenly - one side drops an inch or two lower than the other because the cable on that side has stretched or started to unwind from the drum. Sometimes you'll hear a sharp pop and the door won't move at all; that's usually the cable letting go entirely rather than the spring.
On older extension-spring setups, which are common on Kenner's older housing stock, the first sign is often a scraping sound as a frayed strand catches on the pulley. Catch it there and it's a cable swap. Miss it and the door comes down hard, sometimes pulling the track loose with it. A door that's noticeably harder to lift by hand than it used to be is also worth checking - that's the spring taking on load the cable should be sharing.
What Causes It Around Here
Kenner's median home was built around 1977, a few years ahead of the broader area's 1980 median, which means a larger share of original hardware here - including original cable - never got touched during a renovation. Cable doesn't have a shelf life printed on it, but thirty-plus years of opening and closing wears the strands thin at the drum, and nobody's swapped it because nothing's visibly broken yet.
The mild climate with occasional freeze isn't hard on cable the way a true winter is, but it doesn't spare it either. Humidity sits on exposed galvanized strands, and small amounts of surface rust work their way into the wire over years, weakening it from the inside before you see it from the outside. Combine original-era hardware with decades of that slow corrosion and cable failure becomes a matter of when, not if.
Parts We Carry
For the extension-spring systems common on Kenner's older garages
We carry galvanized aircraft cable in the diameters and lengths that match hardware from the 1970s through 1990s - the era most of this housing stock was built in. We also stock cable drums and the small end fittings that wear out alongside the cable itself, since replacing one without the other is a false economy.
For torsion systems
Which show up more in newer or renovated garages, we carry the matching torsion cable and drum sets. One limitation worth naming: if your door uses an unusual or discontinued track width, we may need to order a part rather than carry it on the truck, which can add a day to the job. We'll tell you up front if that's the case rather than let you wait and wonder.
The Cost of This Job
We don't have a fixed number to quote here, and we'd rather tell you that than make one up. Cable repair cost depends on whether it's one cable or a matched pair, whether the spring also needs attention, and whether it's an extension or torsion system - torsion jobs generally run more because of the drum work involved.
What we can say is that with Kenner's median household income at $64,099, a worn cable replaced before it snaps is almost always the cheaper outcome than waiting for it to take the spring, the track, or a panel down with it. A straight cable swap on a door that's otherwise in good shape is a modest job. A door that's been running on a failing cable for months, with a bent track or a stressed opener to show for it, costs more to put right.
