Murphy, Plano
Cable repair for Murphy homes built mostly after 2000, where torsion-drum hardware and newer opener setups change what breaks and how the fix goes.
Local causes
Murphy's houses mostly went up around 2005, a few years newer than the 2001 median that covers the rest of our service area. That gap matters more than it sounds. Builders working after 2000 almost all put in torsion-spring systems with cables that wind onto a drum at each end of the spring shaft, not the older extension-spring setups where the cable runs along the track to a pulley near the top. Torsion cable failure shows up differently: the door drops crooked, hangs at an angle, or one side binds in the track while the other side moves free. That's the drum losing its grip on a frayed or snapped cable, not a spring giving out.
With about 5,907 households in Murphy, that's a smaller slice of the roughly 78,389 households across the whole area we cover, but the age of the stock is the more useful number for this particular repair. Homes built in that early-2000s wave came standard with steel torsion hardware sized for heavier insulated doors, and the cables on those systems carry more load per strand than what you'd find on an older extension setup. When one frays at the drum or at the bottom fixture, it goes quickly and takes the balance of the door with it.
Timing
A single frayed or snapped cable on a torsion system is a bracket-and-drum job: unwind the opposite spring safely, pull the old cable off the drum, seat the new one, re-tension.
On a standard double door that's typically a straightforward stop once the truck is on site. If both cables have gone, which happens more often than people expect since they age together, we replace the pair rather than the one that failed, so you're not calling again in a few months for the other side.
We run this out of Plano, about 8 miles from Murphy, so we don't carry a local response-time promise the way a shop with a branch in town might. Once we're on site, the cable swap itself doesn't take long.
What adds time is diagnosing whether the drum or the bottom bracket got damaged when the cable let go, which is common if the door was left running on a partly-failed cable before anyone noticed.
DIY or pro
A garage door cable sits under load from a wound torsion spring, and that spring can move fast and hard if you disturb it without the right bars and clamps.
This isn't a job to learn on your own door. Beyond the safety issue, the cable and drum have to match the spring's wind and the door's weight exactly, and getting that wrong leaves you with a door that slams down or won't stay up.
Murphy's median household income runs $165,109, well above the $121,724 median across the rest of our service area, and at that income level the calculation is usually simple: the parts cost is small, the labor to do it right isn't much either, and the downside of getting it wrong - a dropped door, a bent track, a trip to urgent care - dwarfs both.
We'll say plainly what we won't do: we don't talk anyone through a phone-guided DIY cable swap, because the failure mode is a spring letting go under tension, not a stripped screw.
Booking
Tell us it's a cable when you call - which side dropped, whether the door is stuck open or stuck shut, and whether you heard a bang or it happened gradually. That tells us whether we're bringing one cable or a pair, and whether the drum or bottom bracket needs a look too.

Watch-outs
The most common failure on Murphy's torsion setups is a cable fraying where it wraps the drum, usually from years of small misalignments nobody noticed.
Less often, the cable itself is fine but the drum cracked or the set screw backed out, and the door drops even though the cable looks intact - that's a drum replacement, not just a cable swap.
We've also seen cables get cut or crushed by a door that came off its track after a cable already failed on one side; once that happens, the track itself may need straightening or replacing before the cable fix means anything.
And on doors where the opener kept trying to run the door after a cable snapped, the opener's drive gear or belt can take damage too - worth checking so you're not back to square one in a month. None of this is guesswork once we're looking at the drum and bracket in person, but it's why a phone estimate for a cable job is always a range, not a fixed number.
Questions
That's the signature of a torsion cable failing on one drum while the other holds. The door tips because one side is still supported and the other isn't. It's not safe to run the opener like that - the imbalance can bend the track or strain the opener's drive gear further.
Cable and drum hardware for the torsion systems common in Murphy's newer builds is standard stock, so it's typically handled same-visit once we've confirmed the size and wind needed for your door.
Yes. Cables age together since they carry equal load and see the same cycles. If one has frayed from age rather than damage, we'll usually recommend replacing the pair so you're not paying for a second visit shortly after.
