Cables are the part nobody thinks about until one lets go and the door drops several inches on one side. They carry the full weight of the door whenever the springs are doing their job, and they fail quietly, from the inside out.
Updated 2026
A door sitting at an angle has lost a cable on one side, and the other one is now carrying everything. Do not run the opener and do not try to straighten it by hand. Leave it down and call us.
Cables jump their grooves when a door comes off its track, when a spring breaks, or when the opener is run with something in the way. Getting the cable back on is not the whole job — the part that matters is working out why it came off.
Steel cable rarely snaps in one go. It goes strand by strand, starting where it wraps the drum at the top and where it sits in the bottom bracket — the two places nobody ever looks. By the time fraying is visible from the driveway, most of the cable’s strength is already gone.
Corrosion speeds all of it up, and between Clear Lake and Galveston Bay there is no shortage of that. Cables on waterfront doors reach the end noticeably earlier than the same cable a few miles inland.
A cable almost never fails on its own. It fails because something else changed first, and if that is not found the new cable goes the same way.
When a spring lets go, the cables take the whole load in an instant. Very often both parts need replacing and only one of them is obvious from where you are standing.
Corrosion starts at the bottom bracket, the lowest point on the door and the part sitting in whatever comes in under it. Waterfront neighbourhoods see this years sooner than the rest of the city.
If the springs are no longer holding the weight, the cables carry more than they were sized for on every single cycle. They do not complain, they just wear faster.
The drums are the grooved wheels the cables wind onto. A drum that has worn, loosened or moved lets the cable ride wrong, and a cable riding wrong saws at itself.
One good jam can slacken a cable enough to jump the drum. The damage happens in about a second and the door often works fine afterwards, right up until it does not.
✓ Both cables replaced, not just the one that failed
✓ Cable matched to the weight of your door and the size of the drums
✓ Drums checked and reset so the door sits level
✓ Bottom brackets inspected while the door is safely down
✓ Springs and balance checked, since one usually explains the other
✓ Safety reverse tested before we leave
The bottom brackets stay under spring tension even with the door closed, which is why this is not a job to take on with what is in the garage. Every cable repair carries our 90-day workmanship guarantee.
Across League City — including the waterfront neighbourhoods where we see cable corrosion earliest, South Shore Harbour, Waterford Harbor, Marina Del Sol and Marina Bay Park — plus Friendswood and Pearland.
If a spring went at the same time, and it often does, broken spring repair covers what that involves and what it costs.
What people ask us most when a cable has failed.
No. The remaining cable is carrying a load meant for two and the door is no longer level, so it will bind in the tracks and can come off them entirely. Leave it closed until it is repaired.
They were fitted on the same day, they have done the same number of cycles and they have sat in the same air. The second one is not far behind the first, and replacing it now costs you parts rather than another call-out.
Seven to ten years is typical, but it is really about cycles and conditions rather than the calendar. Near the water, where salt air gets into the strands and the bottom brackets, we see them go noticeably sooner.
Treat it as urgent. Fraying means strands have already failed and the remaining ones are carrying that load. There is no reliable way to look at a frayed cable and say how long it has left.
Often, yes, and sometimes the spring went first and took the cable with it. We check both whenever either one fails, because replacing the cable and leaving a spring at the end of its life just brings us back.
We would rather you did not. The bottom brackets stay under spring tension even with the door closed, and that is where people get hurt. Re-seating the cable is also only half the job if nothing has established why it jumped.
Tell us what the door is doing and we will tell you what we think it is. Cable failures go near the front of the queue, because a door in that state is not safe to keep using.
