Cable replacement is one of the most common DFW garage door repairs (behind springs). Here's what to expect for pricing and what causes cables to fail.
DFW Cable Replacement Prices
| Scope | DFW installed cost |
|---|---|
| Cable pair (standard 1/8") | $175–$300 |
| Cable pair (heavy-duty 3/32" or 5/32" for wide/three-car door) | $225–$400 |
| Cable pair + cable drums | $300–$700 |
| Cable pair + drum + bottom bracket replacement | $325–$600 |
Time on-site: 30–60 minutes for a standard pair replacement, 60–90 minutes if drums also need swapping.
Why Cables Always Go in Pairs
Cables sit under matched tension — if one fails from wear, the other is usually within weeks or months of the same failure. Replacing just one leaves your door balanced today but broken again soon. We always quote pairs.
What Causes Cable Failure in DFW
- Rust from summer humidity — DFW's 60–80% summer humidity oxidizes exposed steel cables faster than dry climates
- Bottom bracket water intrusion — where the cable connects to the door, moisture wicks up the strand and creates internal rust
- Drum wear — grooves in the cable drum fray the cable at every open/close
- Spring failure aftermath — when a spring snaps, the shock load stresses the cable. It may not fail immediately, but 2–6 weeks later is common
- Debris in the track — anything the cable rubs against wears it down
When to Also Replace Drums
Cable drums are the aluminum spools at the top of each track that wrap the cable as the door opens. Signs they need replacement:
- Visible grooves worn into the drum surface
- Cable jumps the drum groove during operation
- Drum shows corrosion or cracks
- Drum is loose on the torsion shaft (worn set screws)
Fresh drums add $100–$200 to the job. Skip only if drums are visibly clean and smooth.
Signs Your Cable Is About to Fail
Check both cables once a year for:
- Frayed individual wire strands sticking out of the twisted cable
- Kinks or bent sections
- Rust bloom (orange discoloration)
- Cable jumping off the drum or hanging loose at rest
Any of these = replace before failure. A proactive $250 job vs. an emergency call (spring + cable + hardware, often $600+).
DIY Cable Replacement?
Don't. Cables sit under residual tension even when the door is at rest — disconnecting them without unwinding the spring first can whip the cable end into your face or hand at high speed. Also, the cable end fittings and drum-to-shaft alignment require specific technique to prevent premature failure.
