Clopay Cable & Drum Replacement: The Florida Owner’s Guide
Clopay cable and drum replacement in Florida typically runs $130-$250 installed, and we stock the common Clopay drum sizes and cable lengths on every truck. Most replacements are finished in under an hour, same day you call. Homeowners usually notice the problem when the door hangs crooked, one side lifts faster than the other, or the cable has unspooled from the drum and now sits in a heap at the bottom of the track.
Which Clopay Models This Applies To
Clopay has used several drum designs across their lines, and matching the right one matters. The stamped steel 400-8 and 400-12 drums found on Classic, Premium, and Coachman series doors are not interchangeable with the cast aluminum drums used on heavier Reserve Wood and Grand Harbor models. The cable diameter also varies: 1/8-inch for standard 8-foot doors, 3/32-inch for lighter flush-panel models, and 5/32-inch for wind-load-rated doors common in coastal Florida counties.
We carry OEM-equivalent drums and galvanized aircraft-grade cables that meet Clopay’s original specs, plus the heavier-duty versions for high-cycle applications. The part number is usually stamped on the drum face or printed on a sticker inside the door’s top section. If that label is gone, we measure drum width, bore diameter, and cable groove count on-site. We are an independent service provider, not affiliated with Clopay, but our technicians are factory-familiar with their full product line.
Signs Your Clopay Cable & Drum Replacement Is Failing
- Door lifts unevenly or one side hangs lower. The cable on the lower side has likely slipped its drum groove or frayed enough to stretch under load. The drum may also have a worn groove that no longer grips the cable consistently.
- Loud popping or snapping sound from the header area. This is often a cable breaking strand by strand under tension. Clopay cables in Florida’s salt-air environments corrode from the inside out, so visible rust is usually the late stage of a longer process.
- Cable has completely left the drum and hangs loose. The set screws on the torsion tube have loosened, or the drum’s keyway has wallowed out from years of torque cycling. Either way, the door is now operating on a single cable and the remaining one is overloaded.
- Door feels heavier than usual or opener strains. A frayed cable increases friction in the system and throws off the spring balance. Your opener works harder, burns out faster, and the door may not stay open at the halfway point.
- Visible rust, kinking, or birdcaging on the cable. Florida’s humidity and garage condensation accelerate corrosion. Once a cable develops flat spots or the strands begin to separate like a birdcage, it is past the point of safe operation.
Replacement Cost & What’s Included
| Service | Price Range |
|---|---|
| Clopay cable replacement (single) | $130-$190 |
| Clopay cable replacement (pair) | $180-$250 |
| Drum replacement (each) | $140-$220 |
| Cable + drum replacement (full set) | $220-$340 |
The range depends on door height, whether we are matching a single failed part or replacing both sides as a balanced pair, and whether the torsion system needs re-tensioning after the swap. We state the flat price before starting. Parts, labor, lubrication, and a full safety check are included. Every cable and drum replacement carries our 90-Day Done Right Promise in writing.
DIY or Call Us?
There is a safe way to look and an unsafe way to touch. You can inspect the cable for fraying, check if the drum set screws are loose, and verify the door is disconnected from the opener before anything else. Do not attempt to unwind or adjust the torsion spring to free a stuck cable. The spring stores enough torque to cause serious injury or worse, and Clopay’s heavier solid-core doors common in Florida add even more load to the system.
We carry the right drums, cables, and winding bars on every truck. Most Clopay cable and drum jobs in Florida are done in one visit, no waiting on parts. If you are unsure which drum or cable your door needs, call (844) 871-6326 and we will walk you through identifying it, or come out and handle it start to finish.
FAQs
Expect 8-12 years from quality cables in a dry garage, but Florida’s coastal humidity and salt air can cut that to 5-8 years. Drums typically outlast cables unless the set screws have been over-tightened or the keyway is damaged from a previous improper installation. Call (844) 871-6326 for a free inspection if you are near that range.
No. A frayed cable must be replaced. Splicing or welding compromises the rated breaking strength and creates a weak point that will fail under load, often without warning. We replace cables in matched pairs to maintain even door balance. Call (844) 871-6326 for upfront pricing.
Most Clopay cable and drum replacements take 45 minutes to an hour. That includes removing the old parts, installing the new ones, re-tensioning the spring system, and testing the door balance and safety reverse. We arrive with the parts, so there is no second trip. Call (844) 871-6326 to schedule same-day service.
Yes. We stock 1/8-inch, 3/32-inch, and 5/32-inch galvanized cables, plus the 400-series and heavy-duty cast drums that cover nearly every Clopay door in Florida. If you have an older or specialty model, we will source the exact match and still honor our flat-rate quote. Call (844) 871-6326 to confirm fitment.
