Northglenn, Aurora
Cable repair for Northglenn homes built around 1974, where original lift drums and galvanized cable are common. Serviced from our Aurora shop, 20 miles out.
Symptoms
Most houses in Northglenn went up around 1974, a decade before the median build year across the rest of our service area. That matters here because a door installed in the mid-70s is still running its second or third cable, not its first, and the failure looks different from what you'd see on a newer build.
You hear a bang, then the door won't budge, or it drops crooked and hangs at an angle with one side low. Sometimes it's slower: the door starts jerking partway through its travel, catching and releasing, because one strand of the cable has already frayed and is starting to slip on the drum.
If you can see silver wire poking out of the cable where it wraps the drum, stop using the door. A cable that's shedding strands under load can snap, and a door coming down uncontrolled on a torsion or extension system is not something you want to be standing under.
On the older stock in this town, the failure point is usually where the cable meets the bottom bracket or wraps the drum, not the middle of the run. Cold makes stiff old cable brittle right where it flexes most.
The repair
We pull the old cable off the drum, check the drum itself for wear grooves, and check the bottom bracket where the cable terminates. On a lot of the 1974-era doors in Northglenn, that bracket is original hardware and the mounting holes have worked loose over fifty years of use, so we're often re-securing the bracket at the same time as the cable. We measure the new cable to the drum's factory spec rather than eyeballing the old one, since a cable that's stretched over the decades will read long. Both cables get replaced together on a double door even if only one has failed - mismatched cable age on a shared torsion bar is how you end up back out here in six months for the second one. We check spring tension before we call it done, since a cable job on a door with a spring that's already lost tension will fail again fast.
Pricing
We don't have a flat number to put here for Northglenn specifically. Cable cost depends on drum size, door weight, and whether the bracket or drum needs replacing along with the cable - those add parts cost a straight cable swap doesn't have.
What we can tell you is that a same-visit cable repair is a smaller job than a spring replacement, and a lot smaller than a full door swap.
If you want an exact number before we're standing in front of the door, call and describe what you're seeing; a bent bracket or a grooved drum changes the quote.
DIY or pro
A garage door cable is under tension from the spring system the moment you loosen the wrong bolt, and on a torsion setup that tension is enough to break fingers or worse if the winding cone slips. We don't recommend DIY cable work on a torsion spring door, full stop - this is one job where the tools matter less than knowing how much force is stored in that bar before you touch it. If your door runs on an older extension spring system with exposed springs along the horizontal track, the stakes are lower, but you still need the door fully supported and the springs at rest before the cable comes off. If you're not sure which system you have, that uncertainty alone is the answer: call it in.
Local causes
Northglenn sits in a climate zone with severe cold, and cold is hard on cable in a specific way - galvanized wire loses flexibility as temperature drops, and a cable that's already a few decades old has less give left to lose.
Doors here also see more freeze-thaw cycling on the track and drum than doors in milder climates, and that cycling works moisture into any nick in the galvanizing, which starts rust at the strand level long before you can see it from outside.
Add in that median build year of 1974 - older than most of the rest of the area we cover - and you've got a larger share of original or first-replacement cable still in service, past the point where it should have been swapped on a schedule rather than waited out until it failed.
Watch-outs
The job gets more complicated when the cable failure has already let the door drop hard onto the track or slam down on a car underneath, because that impact can bend the track or crack a panel, turning a cable job into a track-and-panel job. It also gets complicated on doors where the drum itself is worn into a groove from decades of the same cable riding the same spot - a new cable on a grooved drum will just wear through again, so the drum has to go too. We travel from Aurora, about 20 miles out to Northglenn, so if a job turns out to need a part we didn't bring - a specific drum size or a bracket that's no longer stocked for a door this old - that can mean a second trip rather than finishing same-day. We'd rather tell you that up front than promise a one-visit fix we can't guarantee on hardware this age.
Questions
It rarely happens with no warning - the wire usually frays for weeks first, but the fraying is often on the section wrapped around the drum where you can't see it from the ground. On houses built around 1974, that cable has often gone decades without a look, so the first visible sign is the snap itself.
On a double door, yes. Both cables carry the same load history, and if one failed from age or wear the other is close behind. Replacing just one means we're back out for the second one within months, which costs you more in the long run than doing them together now.
No. A frayed or snapped cable means the door isn't held evenly, and it can drop without warning. Leave it closed, unplug the opener if you can reach it safely, and don't park under it until the cable's replaced.
We bring common drum and cable sizes on the truck, but Northglenn's older housing stock sometimes has hardware that's no longer a standard size. If that's the case, we'll tell you on-site and may need a second trip to bring the right part.
