Can You Do This Yourself
A cable under tension is not a weekend project, and we'll say that plainly. On a torsion system the cable works against a wound spring, and on an extension system it works against a stretched one - either way, there's stored energy in that garage that can put someone in the hospital if the cable lets go while you're working on it. We've seen enough half-finished DIY jobs to know where people get hurt: releasing spring tension without clamps, or reaching into the drum area with the door still holding weight on one cable. If you're comfortable and have the right clamps, replacing a hinge or tightening a track bolt is reasonable. Cable work on a door this size isn't.
How Long You Are Without the Door
We travel from Burleson, about 5 miles up the road, so Joshua isn't a long haul for us, but we're not going to promise a same-hour window we can't back up. Once we're on site, a straight cable swap on a standard door usually runs under an hour. If the cable broke while pulling a drum off its shaft, or took a track bracket with it on the way down, that adds time. We'll tell you on the phone, before we drive out, roughly what we're looking at based on what you describe - a door that's stuck halfway with one cable hanging loose reads differently than one that's fully down and square.
The Complications
The complication we run into most in Joshua isn't the cable itself, it's what's attached to it. On a lot of these 1990s-built doors, the cable drum and the spring cone are the same age as the house, and pulling one worn part off a shaft that hasn't moved in decades can reveal a second problem - a seized bearing plate, a drum that's grooved from years of cable wear, or an opener that's been compensating for the slack and straining its gears. None of that shows up until we're actually on the ladder. We also run into doors where a previous repair used a mismatched cable length or gauge, which throws the drum off balance and wears a replacement cable faster than it should.
What the Repair Takes
A standard cable repair means releasing spring tension safely, pulling the old cable off the drum, checking the drum and the bottom bracket for wear grooves, and running new cable sized to match your door's weight and track height. We check both cables even when only one failed, because if one gave out from age the other is on the same clock. On torsion systems we also check the winding cone is still seated right before we put weight back on the door. We don't sell a full door replacement as a fix for a cable problem - if the door itself is sound, a proper cable job should hold for years.
