Clopay cable and drum replacement in San Antonio typically runs $130 to $250 installed, and we stock Clopay-compatible cable and drum sets on our trucks for same-day replacement on most torsion-spring systems. You’ll know this part has failed when you see a frayed cable dangling from the door, hear a loud snap followed by the door hanging crooked, or notice the drum at the top of the shaft spinning without the cable winding cleanly onto it. Most San Antonio homeowners catch the problem the moment the door refuses to lift evenly, or when one side sits visibly higher than the other. Left alone, a snapped cable puts the entire weight of the door on one side, which bends tracks, wears rollers, and can pull the door out of alignment fast.
Key takeaways:
- Installed cable and drum replacement in San Antonio: $130 – $250, written down before any work starts
- We carry Clopay cable and drum sets for torsion and extension spring systems
- Same-day service is available, and our technicians will send you their name and photo before arriving
- Every repair includes the 365-Day Done Right Promise: if the cable or drum fails within a year, we come back and make it right at no charge
Which Clopay Models This Applies To
Clopay builds doors across several series lines, but the cable and drum system is what matters most here. The drums are the grooved wheels mounted on the torsion shaft above the door, and the cables wind around them as the door moves. Clopay uses drum sizes based on door height and spring type, not the trim style or panel design. A 7-foot door takes one drum and cable length; an 8-foot door takes another; a high-lift setup in a San Antonio garage with extra vertical track changes the equation entirely.
Here’s the compatibility gotcha we see regularly in San Antonio: Clopay doors built before roughly 2010 often use smooth-face drums with a specific cable taper, while newer models use grooved drums with a different cable pitch. Mixing a new cable with an old drum can cause the cable to stack unevenly or jump the drum entirely. The reliable way to identify the right part is the cable length itself, measured from drum to bottom bracket, plus the drum’s diameter and groove count. We match by those measurements, not just by “Clopay” on the label. For OEM versus aftermarket: genuine Clopay cables are good quality, but several aftermarket sets built from aircraft-grade 7×19 galvanized steel hold up just as well in Texas heat at a lower price. We stock both and will tell you which one makes sense for your door’s age and use. Doyle Garage Doors San Antonio is an independent service provider and not affiliated with Clopay corporation.

Signs Your Clopay Cable & Drum Replacement Is Failing
- Visible fraying or unraveling on a cable. The cable strands separate before a full snap, usually near the bottom bracket where tension concentrates. If you see hair-like steel wires poking out, that cable is already compromised.
- The garage door hangs crooked or jams partway up. One cable takes the load while the other slips, and the door cants to one side. The rollers then scrape the track and accelerate wear on the side doing all the work.
- A loud snap followed by a banging door. When a cable lets go under tension, it sounds like a gunshot in the garage. The door drops onto the one remaining cable or slams shut, and you’ll likely see the broken cable wound loosely around the drum or spooled on the floor.
- The drum spins without the cable winding on evenly. If the drum has worn grooves or a chip on the edge, the cable won’t seat properly and stacks on one side. Every open and close scrapes the cable against the drum edge, which frays the strands steadily.
- You see a gap between the cable and the drum at rest. With the door closed, the cable should sit snug in the drum groove. A visible gap means the cable has stretched, the drum is worn, or the bottom bracket has pulled loose. Any of those conditions means replacement is the only correct fix, not adjustment.

AfterReplacement Cost & What’s Included
Cable replacement alone in San Antonio runs $130 to $180 per side, depending on door height and cable length. Replacing the cable and drum pair together runs $180 to $250, which is the job most Clopay doors actually need when a failure has gone past the early fray stage. We recommend replacing cables in pairs even if only one snapped, because the surviving cable has been carrying uneven load and is near its failure point too. Every quote at Doyle Garage Doors San Antonio is written down and handed to you before a single bolt is turned. That written price includes the parts, the labor, the adjustment of the spring tension (which is never a DIY step), and the 365-Day Done Right Promise in writing: if the repair fails within one year, we come back and make it right at no charge. We don’t quote over the phone and then add on once we’re in your garage. Aaron Teague built this shop on the rule of never quoting a job he hasn’t looked at first, and every tech under the Threshold Standard follows the same practice.
DIY or Call Us?
We understand wanting to keep a repair simple and cheap, especially when a YouTube video makes a cable swap look like a 20-minute job. Here’s what we’ll tell you straight: the cable and drum system carries the full tension of the torsion spring, and that spring sits wound with enough force to cause serious injury or death if it releases suddenly. That’s not a scare tactic; it’s the reason we tell every customer the same thing. You can safely check the cables visually: look for fraying, look for gaps at the drum, listen for grinding. You should not attempt to remove, rewind, or replace any cable, drum, or spring yourself. The winding cone on a torsion spring stores energy that no hand tools should ever release. One slip with a winding bar is all it takes. We train our technicians for years, and even they treat every spring job with respect. If your Clopay cable is compromised, call (806) 491-1594. We’ll send a background-checked technician whose name and photo you’ll have before they arrive, and the price will be in writing before any work begins.
FAQs
Clopay cables typically last 7 to 10 years in San Antonio’s climate, though the heat and humidity variation accelerates rust and fatigue at the bottom bracket faster than in dryer regions. Drums usually outlast two or three cable sets unless the door has gone out of balance, which chews the drum edges and shortens their life significantly. If your door is over 10 years old and still on original cables, plan on replacement before a snap leaves your car trapped in the garage. Call (806) 491-1594 and we’ll inspect the cable condition and give you a written price before anything gets touched.
No. A frayed cable cannot be repaired in any safe or reliable way. Once strands begin separating, the cable’s load rating drops sharply, and splicing or wrapping the damaged section just creates a weak point that will fail under door weight. We replace the cable, and we always recommend replacing both sides at once so the door lifts evenly. Call us at (806) 491-1594 for an exact quote; estimates are free and in writing.
Most Clopay cable and drum replacements take 60 to 90 minutes on site. The majority of the time goes to safely releasing spring tension, removing the old drum, and reseating the new cable under proper winding tension. If your door needs both cables and both drums plus realignment, expect closer to two hours. We carry the parts on the truck, so there’s no second visit for parts on standard 7- and 8-foot doors.
Yes, we stock Clopay-compatible cable and drum sets for standard 7-foot and 8-foot residential doors, along with parts for LiftMaster, Chamberlain, and Genie openers. If you have a high-lift or custom track configuration, we’ll measure at the appointment and have the specific parts ordered within one business day. Know what’s wrong, know what it costs, know who’s coming; that’s the whole job. Estimates are free; call (806) 491-1594 to schedule.
