The Symptom
The door won't go up, or it goes up crooked and slams back down
One side hangs lower than the other, or you hear a sharp snap followed by the door dropping hard onto the track. That's a cable - the thin steel wire that runs from the bottom bracket up to the drum at the top of the torsion shaft. When it frays and lets go, the door loses the one thing holding it level on that side.
Sometimes it's not a full break
You'll see strands peeling off the cable like a frayed shoelace, usually right where it wraps the drum. That's the warning sign most owners miss until the cable actually parts. A door that's slow to close, or that tips to one side as it travels, is already telling you the cable is on its way out.
Cables don't fail because of one bad day
They fail from thousands of cycles of friction against the drum groove, rust working into the strands, and tension that was never quite right in the first place. On a two-car door, one bad cable usually means the other one isn't far behind - it's seen the same mileage.
How We Fix It
We don't patch a frayed cable. Once the strands start separating, the cable gets replaced - splicing or re-tensioning a damaged cable under spring load is how people lose fingers, and it doesn't hold anyway. The job starts with locking down the torsion spring so the shaft can't spin while we work, then pulling the old cable off the drum and bottom bracket.
We check the drum groove itself while the cable's off. A groove that's worn a channel into the drum will chew through a new cable just as fast as it did the old one, so a worn drum gets replaced along with the cable, not left in place. Same goes for the bottom bracket if the fixture holes have stretched or rusted out - a new cable on a bad bracket is a short-term fix.
On a double door we replace both cables together even if only one has gone, because they're carrying matched tension and a mismatched pair will pull the door crooked again within a season. Once the new cable is seated and the drum re-tensioned, we run the door through a full cycle to check it travels level and the opener isn't fighting the balance. If the spring itself is also worn past safe tension, we'll tell you - that's a separate job, not something we fold into a cable swap to pad the ticket.
Why This Fails Locally
Most of the houses standing in Newark and the towns around it - Harrison, Irvington, Kearny, East Orange, Hillside - went up between 1938 and 1996, with the typical build year sitting around 1958. A garage door installed anywhere near that era has had decades to put cycles on its original hardware, and cables are a wear part with a finite life regardless of how well the door was maintained.
The climate does the rest of the damage. This area sits in a severe cold band, which means the cable and drum assembly goes through real freeze-thaw swings every winter. Cold stiffens the grease in the drum groove, cables drag instead of feeding smoothly, and that extra friction is exactly what frays strands faster than a mild climate would. A cable that might last another two seasons somewhere warmer gives out here first.
Across the service area there are roughly 1,193,552 households and 358,096 owner-occupied houses, a lot of them sitting on housing stock from that same pre-1960 window. That's not a coincidence - it's the same generation of garage doors hitting the same failure point at roughly the same time, which is why cable calls cluster the way they do once the weather turns.
The Cost of This Job
We're not going to put a number here that isn't backed by a real quote
Pricing on a cable job depends on whether it's one cable or a matched pair, whether the drum or bottom bracket needs replacing too, and whether the spring is also past its rated tension. Those are the variables that actually move the ticket, not the day of the week you call.
What we can tell you
Across the service area, median household income runs around $120,958, and most of the jobs we see are owners who'd rather replace both cables and a worn drum in one visit than come back out in six months for the second side. That's usually the more honest call anyway, since a mismatched pair of old and new cables rarely holds level for long.

If the spring is also shot, that's a separate repair
And we'll say so up front rather than fold it quietly into the cable price. A cable job on a door with a healthy spring and clean drum is a straightforward fix. A cable job on a door that's been ignored for years, with a rusted drum and a stretched bracket, costs more because there's more actually wrong with it - not because of markup.
