Clopay cable and drum replacement in Alpharetta typically runs $130 – $250 installed, and we stock Clopay-compatible cables and drums on our trucks so most jobs are done in a single visit. What owners usually notice first is that the door hangs crooked, makes a grinding noise, or won’t lift evenly. The cable has either snapped, slipped off the drum, or the drum itself has worn enough that the cable no longer tracks cleanly.
This page covers what fails, what it costs, which Clopay models we service, and what you should know before anyone touches your door. We’re an independent service provider, not affiliated with Clopay, but our technicians train on Clopay hardware specifically because so many homes across Alpharetta have it.
Which Clopay Models This Applies To
We replace cables and drums across the Clopay line: the Classic series, Gallery, Coachman, Canyon Ridge, and the newer Bridgeport and Modern Steel collections. The compatibility gotcha most Alpharetta owners don’t know is that Clopay uses different drum profiles depending on the spring system. Torsion spring setups use a tapered drum that must match the door’s weight and cable length, while extension spring systems on lighter single-car doors use a flat pulley drum. Installing the wrong profile means the cable either stacks unevenly or slips within a few cycles.
The fastest way to identify what you have is to look at the sticker on the end stile of the door panel just inside the garage. That label lists the door model and often the original hardware spec. If the sticker’s gone or faded, which we see regularly on Alpharetta homes with west-facing garages that catch years of afternoon sun, we take measurements on site: door height, weight, drum cone taper, and cable diameter. For most Clopay residential doors, cable diameter runs 1/8 inch or 3/32 inch in a 7×19 aircraft-grade strand. The drum replacement decision comes down to whether you want OEM Clopay parts or a quality aftermarket equivalent. We carry both. OEM is the safest match when the rest of the hardware is original. A good aftermarket drum from the same spec range costs less and performs identically in most cases, but we’ll show you why one might fit your door better than the other before we quote anything.

Signs Your Clopay Cable & Drum Replacement Is Failing
- The door hangs visibly crooked when opening. One cable has stretched or slipped on the drum, so one side lifts before the other. The door’s fighting itself every cycle.
- You hear a grinding or squealing sound near the top of the door. The cable is dragging against a worn drum groove instead of seating cleanly. The groove gets polished smooth over time and loses its grip.
- The cable looks frayed or has visible broken strands. Georgia humidity accelerates corrosion on cables that have lost their galvanized coating. Once strands start separating, the cable is done.
- The cable has come off the drum entirely and is wrapped loosely around the shaft or hanging against the wall. This often means the drum’s set screws loosened or the drum itself has a hairline crack from years of torsion stress.
- The door stops partway up or slams when closing. A drum that’s no longer synchronized with the opposite side means the door’s travel is uneven, which puts extra load on the remaining cable and the springs.

AfterReplacement Cost & What’s Included
Cable replacement for a Clopay door in Alpharetta runs $130 – $250 per side, installed. If the drum needs replacing as well, the job is usually at the upper end of that range, since the drum and cable are replaced as a matched pair on that side. What drives the difference is mostly door weight: a heavy double-wide Canyon Ridge door needs heavier cable and more labor than a single-car Classic door.
The price you’re quoted is the price you pay. We hand over a written quote before any work starts, and that number includes the parts, the labor, the adjustment to the opposite side so the door tracks true, and a full cycle test once everything’s back together. Every cable and drum replacement we do is covered by our 365-Day Done Right Promise, which simply says if it’s not right, we come back and make it right, no negotiation needed. Jesse Calder is the first to say a cable job that doesn’t check the springs and tracks is just a rescheduled problem, so we read the whole system before we touch anything.
DIY or Call Us?
There are two things an owner can safely do. One: look at the cables visually and note where they’re frayed or off the drum so you can describe it accurately on the phone. Two: test the door’s balance by pulling the release handle and lifting the door halfway. If it holds, the springs are doing their job and the issue is likely isolated to the cable or drum. If it drops, you have a spring problem too, and that changes the repair.
What we’d ask you not to do is attempt the cable or drum removal yourself. The cables on a Clopay torsion system run under the same tension as the springs, and that tension is stored energy that releases the wrong way if the drum or set screws aren’t handled in the right order. A snapped cable under load moves fast enough to cause serious injury. We’ve taken over more than a few Alpharetta jobs where the cable was halfway off and the homeowner wisely stopped. That was the right call. If the door’s crooked, grinding, or hanging by one cable, call us at (229) 471-5755 and we’ll have a technician out, with the parts on the truck.
FAQs
In Alpharetta’s climate, you can expect Clopay cables to last 8 to 12 years and drums to outlast them by several years, though it depends heavily on how often the door cycles and whether the springs have ever been replaced, since old springs put extra strain on the cables and drums. If you’re at the 10-year mark and seeing frayed strands, replacement now is cheaper than a snapped cable later. Call us for an on-site assessment and an exact price.
No, a frayed or damaged Clopay cable cannot be safely repaired; the entire cable must be replaced once strands begin separating, because the cable’s load rating is compromised and the next failure point is unpredictable. We also check the drum on that side, since a worn drum will chew through a new cable quickly. For a quote, call (229) 471-5755.
Most Clopay cable and drum replacements are finished in about an hour and a half, including the rebalancing of both sides and a full cycle test, so you’ll have the door working the same day we arrive. We keep common Clopay cable sizes and drum profiles on the truck, which is what makes the single-visit turnaround possible. Call (229) 471-5755 and we’ll confirm the parts are loaded before we head your way.
Yes, we stock Clopay-compatible cables in the common residential sizes, plus drums for both torsion and extension spring setups, alongside parts for LiftMaster, Chamberlain, and Genie openers, so most Alpharetta calls are completed in one trip. If your door needs a non-standard spec we’ll tell you on the phone and order it before scheduling. Reach us at (229) 471-5755 to check availability for your specific model.
