Replacing a Clopay cable and drum in Pasadena typically costs $130 – $250 installed, and we keep compatible cables and drums on our trucks so most jobs are finished in one visit, often the same day you call. The cable is the braided steel line that runs up each side of the door and wraps around the drum; the drum is the grooved aluminum or steel spool at the top of the torsion shaft that guides the cable as the door moves. When either fails, you’ll usually see it before you hear it: the door hangs crooked, one side sits higher than the other, or a cable is visibly frayed and dangling. If the door still moves at all, it moves rough and you can feel the strain through the wall.
Which Clopay Models This Applies To
Clopay builds doors across several series lines, and the cable and drum setup varies by door weight, height, and spring configuration. You’ll find these parts on Classic, Gallery, Coachman, Bridgeport, and Reserve Collection doors, as well as Clopay’s commercial and value-line models. The compatibility gotcha many Pasadena homeowners run into is this: Clopay pairs cable length to door height and drum groove width to cable diameter, and mixing a standard 7-foot cable onto an 8-foot door is a common cause of repeat failure. OEM Clopay cables are aircraft-grade galvanized steel in 1/8-inch or 5/32-inch diameter, depending on door weight; the drum must be cut for the correct diameter or the cable binds. Quality aftermarket equivalents that match those specs work fine, and we install both, but we always verify the door’s size and spring type before selecting the part. Brock Garage Doors Pasadena is an independent service provider, not affiliated with Clopay Corporation, and we stock cables and drums that fit Clopay geometry alongside parts for LiftMaster, Chamberlain, and Genie openers.

Signs Your Clopay Cable & Drum Replacement Is Failing
- Door hangs uneven or crooked. One cable has stretched or begun to separate, so one side carries less load. You’ll see a visible gap at the bottom of the door on the side that’s dragging.
- Frayed cable strands near the drum or bottom bracket. Cables don’t fail all at once; individual strands snap over weeks of use. Once you see fraying, the remaining strands are carrying more than their rated load and failure is close.
- Grinding or scraping sound when the door moves. A worn drum groove or a cable that’s jumped the groove creates metal-on-metal contact. The noise usually tracks to one side.
- Cable loose or completely off the drum. This frequently happens when a door is run with a broken spring; the cable loses tension and falls out of the groove. If you see a loose cable, do not run the door.
- Door jerks or catches mid-travel. A drum that’s worn unevenly or a cable with a kink will feed erratically, making the door stutter as it moves.

AfterReplacement Cost & What’s Included
In Pasadena, Clopay cable and drum replacement runs $130 – $250 installed, with most single-door cable jobs landing between $150 and $200. If the drum itself is scored or cracked, or if both drums need replacement to match the cable diameter, you’ll be toward the upper end of that range. We hand over a written quote before any work starts, so the number you approve is the number you pay. Every cable and drum replacement includes new cable, inspection of both drums and the bottom brackets, lubrication of the torsion shaft bearings, and a full cycle test. Your repair is covered in writing for 365 days. If it fails in that window, we return at no charge.
DIY or Call Us?
You can safely check a few things: look for frayed strands, see if the door hangs level when closed, and visually confirm both cables are seated in their drum grooves. What you should not do is attempt to re-seat or replace a cable yourself. The cables work under tension from the torsion spring, the thick coiled spring mounted above the door that bears most of the lifting load, and that spring holds enough force to cause serious injury if mishandled. Even with the door fully open and the spring relaxed, releasing the wrong bolt in the wrong order sends a cable and drum spinning. This is work for a trained professional with the right winding bars and a healthy respect for what a wound spring can do. If you’re seeing a frayed cable or a crooked door in Pasadena, call (626) 788-0967 and we’ll get it sorted.
FAQs
Clopay cables typically last 7 to 12 years in Pasadena’s climate, though doors near the foothills or within a few miles of the coast can see earlier wear from moisture exposure and salt air. Drums last longer, often 15 years or more, but a scored groove from a cable that was run while frayed will shorten their life considerably.
No. Once a cable shows fraying, the structural integrity of the remaining strands is compromised, and patching or splicing a garage door cable isn’t a repair we’ll do or recommend. Replacement is the only safe fix, and at $130 – $250 it’s far less expensive than the damage a snapped cable can cause to your door, your vehicle, or a person. Call (626) 788-0967 and we’ll give you an exact quote before any work begins.
Most Clopay cable and drum replacements take 45 to 90 minutes on site, assuming the door and springs are otherwise in serviceable shape. If we find the spring also needs replacement, the visit runs longer, and we’ll tell you that before we start the extra work, with a written price for the full job.
We carry cables and drums sized for the most common Clopay door heights and weights in the Pasadena area on every truck, including 7-foot and 8-foot cable sets in 1/8-inch and 5/32-inch diameters. For less common commercial or high-cycle models, we source the exact spec and return within a day or two. Call (626) 788-0967 and we’ll confirm what we’re bringing to your door.
