Most of the garage doors in Tempe went up between 1985 and 2007, with the median build year sitting at 1995. That means a lot of the original lift cables on these doors are somewhere between twenty and forty years old - well past the point where the galvanized coating is doing much for the strand underneath.
Heat is the other half of it. Tempe's summers run hot enough, long enough, that the light lubricant on a cable dries out faster than it would almost anywhere else. Once that coating goes, the strands rub against each other and against the drum every time the door cycles. You get fraying first, usually near the bottom bracket or where the cable wraps the drum, and then one hot afternoon under load, it lets go.
Across the four main pockets of housing stock in this part of the Valley - mostly 1980s and 90s builds - the pattern repeats house after house. It's rarely one bad cable in isolation. If a house was built in that window and the cables haven't been swapped since, the other side of the door is usually not far behind.
A garage door is under spring tension whether the cable is broken or not, and that tension is what makes this one of the few home repairs we tell people flat out not to attempt without the right bar and clamps. A snapped cable on a torsion-spring door means the other cable and the springs are still loaded, and the door can drop or the drum can spin hard enough to take a finger with it.
If the door is already down and won't move, that's actually the safer state to leave it in. Don't force the opener, don't try to muscle the door up by hand, and don't disconnect anything at the top until someone's looked at the spring tension. If you're comfortable with hand tools and want to inspect before calling, you can visually check the cable at the bottom bracket and the drum for fraying - that costs nothing and tells you a lot. Replacing the cable itself is where we draw the line for a DIY recommendation.
We don't post a flat number for cable repair because the job isn't the same on every door. A single frayed cable on a lighter door is a different job than both cables gone on a heavier insulated door, and the drum, bottom bracket, and spring tension all get inspected as part of the same call - sometimes one of those needs attention too, sometimes it doesn't.
What we can tell you is how we price it: you get a number before any work starts, based on what's actually wrong once we're looking at the door, not a phone-quote guess. If the cable failure has also bent a bottom bracket or damaged the drum, that gets called out separately so you know why the price moved. We'd rather tell you we need to see it than make up a figure that doesn't hold once the truck's in the driveway.
A cable that's about to go doesn't usually fail without warning. Look for a door that jerks or hangs unevenly partway through its travel, one side visibly lower than the other when it's open, or a faint popping or scraping sound near the top corners as the door moves. Fraying often shows up first as a few loose wire ends sticking out where the cable loops the bottom bracket.
Once a cable actually snaps, the door will usually stop dead, tilt hard to one side, or drop suddenly if you're mid-cycle when it happens - which in a hot Tempe afternoon is exactly when a stressed, dried-out cable is most likely to let go. If your door won't budge and one side looks lower than the other, leave it alone and get it looked at before anyone tries the opener again.
It depends on whether one or both cables failed, whether the drum or bottom bracket took damage, and how heavy the door is. We inspect first and give you a firm number before starting work rather than quoting blind over the phone.
It rarely happens with zero warning - fraying at the bottom bracket or drum usually starts weeks before a full break. In Tempe's heat, dried-out lubricant speeds up that fraying, so a cable that looked fine a month ago can go quickly once it starts.
Yes, a broken cable on one side just means the door won't open safely, not that your car is trapped, unless the door was mid-cycle when it failed. Leave the door alone and don't force the opener until the cable and spring tension are checked.
Yes. Cables run from the bottom brackets to the drums and carry the door's weight during travel; springs store the tension that lifts it. A cable snapping doesn't always mean a spring failed, but a technician checks both since they work under the same load.
