Cable repair, not replacement
A snapped cable on one side of a double door is a parts-and-labor job, not a door replacement, and at this income level that distinction is the whole point of the call.
Riviera Beach, Jupiter
Snapped or frayed garage door cable in Riviera Beach, FL? We match cable gauge and drum size to 1980s-era doors instead of pushing a full replacement.
Job timing
Median household income in Riviera Beach sits at $62,152, well below the $86,562 median across the wider service area. That gap matters here because it decides which repairs get quoted and which get talked through first.
A snapped cable on one side of a double door is a parts-and-labor job, not a door replacement, and at this income level that distinction is the whole point of the call.
We don't carry a crew stationed in Riviera Beach - the truck comes 10 miles from Jupiter for every job, so there's no local branch number to quote you, just the drive.
Once the truck is on site, cable work itself is usually the shorter job on the ticket: pull the broken cable, check the drum for wear where it rode, cut and seat the replacement, rebalance the door against the spring. It's the diagnosis before that - is it just the cable, or did the drum groove under the strain - that decides whether the visit runs long or short.
DIY or pro
A garage door cable runs under spring tension, and that tension doesn't go away just because the cable snapped. If one side let go, the other side is usually still loaded, which means the door can drop, twist, or the opposite cable can whip loose while you're standing under it. Unwinding a winding cone on an extension spring, or backing off a torsion spring to get the drum off, takes a bar and a stance most homeowners have never practiced. We're not going to pretend this is a weekend project with the right YouTube video. If you can see the broken cable hanging loose and the door is stuck halfway, the safest thing you can do yourself is leave the opener unplugged, block the door where it sits, and make the call. Anything past that - pulling the drum, re-threading cable - is where a slipped bar or a dropped spring turns a $150 repair into an ER visit.
The repair
Cable repair on a residential door comes down to matching gauge and length to the drum and the spring system the door was built with.
Houses across the service area were built mostly in the 1980s and 90s, with a service-area median build year of 1981, and Riviera Beach's housing stock lines up close to that, centered around 1980.
Doors from that era were set up with a mix of extension spring systems on the sides and early torsion conversions overhead, and the cable spec for one doesn't fit the other. Get the gauge wrong and the cable either slips on the drum or binds and frays again inside a year.
The job itself is: release tension safely, pull the failed cable off the drum or pulley, inspect the drum groove and the pulley bracket for the wear that caused the failure in the first place, cut new galvanized cable to length, re-seat and re-tension, then run the door through a full cycle to check it tracks straight and doesn't drift.
Warning signs
A frayed or snapped cable shows up as a door that hangs crooked - one corner low, the other still roughly level - or a door that won't move at all because the opener senses the imbalance and refuses to run. Sometimes you'll see the cable itself, a loose coil of thin wire dangling near the bottom bracket, before the door even fails fully. On older extension-spring setups common in houses built around 1980, the first sign is often a door that slams the last foot of travel instead of settling, because one side is still carrying spring tension the other side lost. The mild temperate climate here doesn't put the kind of rust load on steel cable that colder, wetter regions see, so when a cable fails here it's almost always fatigue from years of cycling, not corrosion eating through the strands.
Watch-outs
With roughly 13,567 households in Riviera Beach and most of that housing stock going up around 1980, we run into a fair number of doors that have had one piece replaced over the decades but not the rest - a newer opener bolted onto an original extension-spring frame, or a replacement cable from a prior repair that's the wrong gauge for the drum it's riding on.
That mismatch is the complication that turns a straightforward cable swap into a longer visit: if the drum is worn from years of the wrong cable size, swapping the cable alone just repeats the failure.
Sometimes the honest call is to replace the drum and cable together rather than patch one part. We'll tell you which one you're looking at before we start, not after.
On the truck
The truck stocks galvanized aircraft cable in the common residential gauges and lengths used on both extension-spring and torsion-spring setups, along with standard drums, pulleys, and end fittings. For a door built in the early 1980s style still common in this part of the service area, that covers the repair in one visit most of the time. What doesn't always come standard is a drum or bracket sized for a door that's been modified or replaced piecemeal over 40 years - those sometimes need a part ordered rather than pulled off the shelf. We'd rather tell you that up front than send you a second invoice for a second drive out from Jupiter.

Questions
Almost always a repair. A snapped cable alone doesn't mean the door or opener is done - it means the drum takes a new cable and the door gets rebalanced. Replacement only makes sense if the drum, track, or panels are also damaged, which is a separate inspection, not assumed.
Doors from around 1980 in this area were built with either extension-spring or early torsion hardware, and each uses a different cable diameter and drum profile. Put the wrong gauge cable on the wrong drum and it slips or frays again within months, which is a repeat call nobody wants.
No. The truck runs out of Jupiter, about 10 miles out, for every Riviera Beach call. There's no local branch to call separately - the scheduling and the drive both route through Jupiter.
It helps with rust, since the service area's mild temperate conditions don't put the corrosion load on steel cable that colder, wetter climates do. Most failures we see here are fatigue from years of cycling, not rust eating through the strands.
