Coppell, TX
Broken or fraying garage door cables on Coppell homes built 1959-2014. We explain what fails, why, and when a cable swap turns into a full replacement job.
DIY or pro
A snapped lift cable looks like a job you could handle with a wrench and an afternoon. It isn't, and here's why: the cable you're replacing is under load from the torsion spring the whole time you're working, even with the door down.
If that spring lets go while you're threading a new cable through the drum, it can take a finger or worse with it. We get calls every year from people who started this job and stopped halfway when they realized the spring wasn't going to hold still.
What you can safely do yourself: look at the cable. If you see rust, frayed strands, or a kink near the bottom bracket, that's your sign to call before it snaps on its own, usually while the door is halfway up and nobody's watching.
Cables rarely fail all at once from nothing - they fray for weeks first. Catching that fray costs you a service call. Missing it costs you a door stuck at whatever angle it broke.
Our process
Both cables get replaced together, even if only one broke. They carry the same load and age at the same rate, so the second one is close behind the first - we've pulled plenty of matched pairs where one was still holding by three strands.
We release the spring tension, pull the old cables off the drums, and run new galvanized cable sized to your door's weight and drum diameter, which varies more across Coppell than you'd expect given how much of the housing here shares a build era.
We check the drums, the bottom brackets, and the track alignment while we're in there, because a cable that frayed against a burred drum or a bent bracket will fray again on the replacement if we don't fix what caused it.
On a standard double door this is usually a same-visit job. On doors with worn-out rollers or a track that's pulled loose, we'll tell you before we start if the cable is really the whole story or just the first thing to give out.
Warning signs
Most Coppell garage doors are on torsion springs with cables running to drums at each end of the shaft, and the failure pattern is pretty consistent.
The door jerks or drops unevenly on one side before it opens all the way. You hear a snap and the door won't move at all, sitting cocked at an angle.
Sometimes it's quieter - a slow fray that shows up as a scraping sound near the top of the travel, months before the cable actually lets go. On homes with the original opener and hardware still in place, cable wear tends to show up alongside worn rollers, since both take the same daily cycling.
If your door is sagging on one side when it's fully closed, or one cable looks visibly looser than the other, that's not cosmetic - it means the drums aren't sharing load evenly anymore, and that shortens the life of whatever cable is doing the extra work.
Local causes
The housing stock across this service area runs mostly 1959 to 2014, with a median build year around 1999, so a large share of the doors we're called out to see are original or close to it - meaning original cables, original drums, a couple of decades of daily cycling with no failure point until now. That's not a defect, it's just cable life catching up with the calendar.
Heat plays a smaller role here than in harsher climates, but Coppell's summers still run hot enough to dry out cable lubrication and speed up rust once a coating nicks or wears thin, especially on doors that sit facing full sun most of the day. We don't see the cable failures tied to ice or freeze-thaw that colder regions deal with - this is a wear-and-heat story, not a cold-snap one. Across the roughly 55,758 owner-occupied houses in our service area, cable wear tracks pretty closely with how old the door hardware is, not how the house is landscaped or where it sits on the lot.
Questions
We don't have a set number to quote here since it depends on drum size, door weight, and whether the rollers or track need attention too. We'll give you a firm price on site before any work starts, not a phone estimate.
If the cable snapped, the door likely won't move at all, or it's stuck at an angle. Don't force the opener or try to lift it manually - the other cable and the spring are still under load and can shift suddenly.
Both, as a rule. They wear at the same rate since they carry the same load, and replacing just one means you're back out here in a few months for the second failure.
No, but they're often mistaken for each other. A broken spring usually makes the door feel heavy or impossible to lift by hand. A broken cable usually leaves the door stuck at an angle or lets one side drop faster than the other.
