Clopay Cable & Drum Replacement: The Denton Owner’s Guide
Clopay cable and drum replacement in Denton typically runs $130-$250 installed, and we stock the common Clopay drum sizes and cable lengths on our trucks for same-day completion. Most jobs take under two hours once we’re on site. You’ll usually notice the problem when the door hangs crooked, one side lifts faster than the other, or you spot a frayed cable hanging loose above the track.
Which Clopay Models This Applies To
Clopay builds doors across several series, and the drum and cable setup changes with door height and weight. The Classic Collection and Gallery Collection steel doors use standard-lift drums in 8-, 9-, and 16-foot widths, while the Avante and Reserve Wood lines often need high-lift or vertical-lift drums for taller ceiling clearances. The part number is stamped on the drum hub itself, usually a four-digit code starting with 4, 5, or 6 depending on drum diameter.
Clopay’s OEM cables are 7×19 galvanized aircraft cable, but we also carry quality aftermarket equivalents rated to the same 2,000-pound breaking strength. For most Denton homes built in the 1990s and 2000s with 7-foot Clopay doors, the 1/8-inch diameter by 132-inch length fits. If your door is 8 feet tall, the cable jumps to 156 inches, and that’s a common mismatch we see when homeowners order online without measuring the old cable end-to-end. Mainspring Garage Door Co. is an independent service provider, not affiliated with Clopay, but we’ve worked on enough of their doors to know the spec sheet by memory.
Signs Your Clopay Cable & Drum Replacement Is Failing
- The door sits crooked when closed. One cable has stretched or slipped off its drum, so that side of the door hangs lower. The torsion spring is still doing its job, but the uneven load will warp the top section over time.
- A loud bang from the garage, then the door won’t move. The cable snapped under tension. Clopay cables in Denton typically last 8-12 years, but our hot summers and occasional ice events accelerate fraying at the bottom loop where the cable meets the bottom bracket.
- The cable is unwound and dangling from the drum. The set screws on the drum loosened, or the drum itself has cracked at the hub. We see this more on Clopay doors with plastic-core drums installed before 2010.
- The door rises fast on one side and struggles on the other. One drum is not winding cable evenly, often because the drum bore has worn oval from years of torque. The cable piles up instead of laying in neat coils.
- Visible rust or broken strands at the cable loop. Even a few snapped wires mean the cable is living on borrowed time. Texas humidity gets into the garage more than people expect, especially in Denton homes near Lewisville Lake where the morning air sits heavy.
Replacement Cost & What’s Included
| Service | Price Range in Denton |
|---|---|
| Single cable replacement (one side) | $130-$190 |
| Both cables + both drums | $180-$250 |
| Drum replacement (each) | $40-$75 part + labor |
| Emergency / after-hours call | No additional fee |
What drives the range: door height (taller means more cable), whether the drum is standard or high-lift, and if the bottom bracket or cable fittings also need replacement. We state the flat price before touching a tool. Parts, labor, and the 90-Day Done Right Promise are all included in the quote. No add-ons after the fact.
DIY or Call Us?
There’s a safe middle ground here. You can eyeball the cable for fraying, check if the drum set screws are tight, and verify the door is unplugged from the opener before we arrive. What you should not do is release tension from the torsion spring or try to wind a new cable onto the drum yourself. The spring above your Clopay door holds lethal force. We’ve seen experienced DIYers in Denton neighborhoods like Southridge and Oakmont lose fingers or worse.
If the cable is simply off the drum and the drum itself looks intact, that might be a quick reset. But if the cable snapped, something caused it, and that something needs diagnosing. We quote it flat, we do it right, and we leave the door working. Call (817) 623-1087 and we’ll talk through what you’re seeing.
FAQs
Most last 8-12 years with normal use. Denton’s heat cycles and humidity shorten that if the garage isn’t ventilated well. Call (817) 623-1087 for a free look if you’re past the decade mark.
No. Once the 7×19 wire strands start breaking, the cable’s rated strength is compromised and splicing is not safe. Replacement is the only sound option. We carry the right length on the truck and can swap it today.
Most Clopay cable and drum jobs in Denton take 60 to 90 minutes. If both sides need work and the bottom brackets are corroded, plan on two hours. We finish in one visit because the parts travel with us.
Yes. Our trucks carry the common Clopay drum sizes and cable lengths for standard residential doors. For specialty high-lift or commercial-grade setups, we’ll confirm by phone and source same-day if needed. Call (817) 623-1087 to check your specific model.
