Where the money actually goes
A pair of galvanized aircraft cables is one of the cheapest parts on the whole door. So why does the job cost real money? Because those cables are under the same tension as your torsion springs. Replacing them safely means clamping the door, unwinding the springs with proper bars, swapping both cables, rewinding to the correct turn count and rebalancing the door. Done wrong, the door can free-fall or the spring can unload into someone's forearm. You are paying for a controlled procedure, not two pieces of wire.
A proper OKC-area quote should spell out three things:
- Both lift cables, sized to your door height and drum type
- Labor covering the spring unload, rewind and rebalance — the bulk of the job
- Worn cable drums, replaced as a pair if the grooves show wear
Why cables fail early in central Oklahoma
Cables fray from the bottom up, right where they anchor near the floor. Three local accelerants show up over and over on our repair calls: winter road brine tracked in on tires that corrodes the bottom loop, red-clay grit that works into the strands and acts like sandpaper, and slab moisture in older garages around Del City and Midwest City where the anchor bracket sits in occasional standing water. If you see rust bloom or a few broken strands sticking out like whiskers, the cable is on borrowed time.
One caution worth repeating: a door with one snapped cable will often still move, but it moves crooked, and that is exactly how doors jump their tracks. The follow-on damage costs far more than the cable job, as our answer on off-track repair pricing lays out. Stop using the door and call.
Always replace cables in pairs, and check the neighbors
Both cables went on the same day and have carried the same load for the same number of cycles. Replacing only the broken one nearly guarantees a second call within months, which is why any reputable company prices the pair. A good tech will also inspect the parts that live and die with the cables: drums for groove wear, bottom brackets for rust, and springs for stretch. We fold that inspection into the job at no extra charge, and if you want the whole system gone through once a year, a maintenance tune-up catches fraying cables long before they let go.
