Clopay Cable & Drum Replacement: The Garland Owner’s Guide
A Clopay cable and drum replacement in Garland typically runs $130 to $250 installed, parts and labor included, and we carry Clopay-compatible drums and cables on the truck for same-day service in most cases. You’ll usually discover the failure when the door starts lifting unevenly, one side hangs lower than the other, or you hear a metallic pop followed by the door jamming halfway up. The cable is the steel wire that runs up each side of the door and wraps around the drum, which sits on the torsion shaft above the opening; when either one goes, the door can’t travel evenly and the whole system works harder, which means more wear on every other component.
Here’s what Garland homeowners need to know about getting this fixed right the first time, including what fails first, what it should cost, and what kind of documentation you should expect before anyone touches your door.
Key takeaways:
- Installed replacement cost in Garland: $130-$250, written price before the work starts per Clause 1 of The Haven Standard
- We stock Clopay-compatible cables and drums, plus OEM Clopay parts when the door needs a specific profile
- The photo record you receive shows the failed part before we quote the replacement, not after
- This is not a safe DIY job if the torsion spring is still under tension; one honest paragraph on that below
- Servo Garage Doors Garland is an independent service provider, not affiliated with Clopay
Which Clopay Models This Applies To
Most residential Clopay doors built in the last 25 years use a standard torsion-system cable and drum, but there are two compatibility points that matter. First, the drum: Clopay uses a 4-inch drum on most standard-lift doors, but high-lift and vertical-lift configurations, common in garages with tall ceilings around Firewheel Town Center and newer builds off Naaman School Road, take a different profile. Second, the cable length and diameter: 7/32-inch aircraft-grade cable is the Clopay standard for doors up to 8 feet tall, while 8-foot and taller doors often step up to 1/4-inch. If you match the drum but not the cable, the door will still drift out of level within a few weeks.
You can usually identify the right part by looking at the side of the door panel for the Clopay label with the model number, or by opening the parts guide stapled to the door’s left jamb from the original install. If neither is present, we match by measuring the drum’s outer diameter and the cable’s wire gauge on site. For Clopay doors specifically, we recommend OEM drums when the door is under 10 years old and still on its original torsion spring; aftermarket equivalents from the same Garland suppliers we use for LiftMaster, Chamberlain, and Genie openers work well on older doors, but the OEM drum’s groove profile tends to seat the cable more cleanly on newer models. We’ll quote both options as written line items so you can see the difference before deciding.
Signs Your Clopay Cable and Drum Is Failing

- Door lifts crooked or binds on one side. This is the classic cable failure signal: one cable has slipped or snapped, so the door rides on the remaining cable and twists in the track. You’ll hear it scraping against the track and may see the bottom panel kick out slightly.
- Frayed or rusted cable strands visible near the drum. Garland’s summer humidity and spring rain cycles put moisture against steel cables, and the first strands to break are usually right where the cable exits the drum. You’ll see it if you look up at the shaft with the door closed.
- Loud pop then the door slams down crooked. When a cable snaps under load, the door drops on one corner fast. If you hear this, stop using the door and pull the release cord carefully if you need to get a car out; the remaining cable is now holding extra tension.
- Cable has jumped the drum groove and is wrapped around the shaft. This happens when the drum’s groove wears or the cable stretches. The cable spools over itself, the door jams, and the opener’s force setting usually kicks in and stops it but not before the top panel takes a hit.
- Door jerks during the first foot of travel. A drum that’s worn on one side can’t feed cable at the same rate as the other side, so the first few inches of lift feel rough. This gets worse in cold snaps, when the metal contracts and the cable binds in the worn groove.

AfterReplacement Cost & What’s Included
In Garland, expect to pay $130 to $250 for a Clopay cable and drum replacement installed. The low end covers one cable and one drum replacement with a basic 4-inch drum profile on a standard 7-foot door. The high end covers both cables and both drums, or a high-lift drum profile that requires more bench time to set. Here’s how it breaks down:
- Single cable replacement (one side): $130-$180 installed
- Single drum replacement (one side): $140-$210 installed
- Both cables and both drums (recommended when one side fails): $210-$250 installed
Every quote includes the written scope and flat price before work starts, the actual replacement, a rebalance of the door’s travel and force settings, and the documented photo record when we leave. The photo record shows the failed drum or frayed cable on the shaft before removal, the replacement part seated in place, and the door in the fully open and fully closed positions. If we recommend doing both sides at once, it’s not an upsell; when one cable fails, the other has the same number of cycles and the same exposure. We quote it as a separate line item, and if you want to do one side now, we’ll note the remaining side’s condition on the written scope.
DIY or Call Us?

What a Garland homeowner can safely check: with the door closed, look at the cables on both sides and check for fraying, rust, or kinks near the drum. You can also run the door halfway and watch whether it stays level. Those checks cost nothing and help you describe the problem accurately when you call.
What you should not do: remove or replace a cable or drum yourself while the torsion spring is wound. The spring is holding enough stored energy to break a wrist or worse if it unwinds without the proper winding bars and technique. That’s the honest line: we replace these parts with the spring safely unwound and the door braced, and then we bring the spring tension back to the manufacturer’s spec, not just “tight enough.” Name the part, quote the number, then do the work. If you’re in Garland and the cable has already snapped, call (469) 949-6806 and we’ll give you the installed price before we dispatch anyone.
FAQs
Cables typically last 7 to 12 years in Garland’s climate, with the drum grooves wearing fastest on doors that cycle more than four times daily. Garland’s humidity accelerates cable rust at the drum exit point, which is where most cables fail first.
No. A frayed cable has already lost strands and can’t be spliced back to original strength. Replacement is the only correct repair, and it’s the cheaper option anyway at $130 to $180 installed versus gambling on a door coming down on a car.
Most single-door Clopay cable and drum replacements in Garland take 45 to 75 minutes on site, including the safety checks and the photo record. Both sides run closer to 90 minutes.
We stock Clopay-compatible cables and 4-inch drums on the truck, and we carry OEM Clopay drums for the standard-lift models most common in Garland. Oddball high-lift profiles may require a next-day order, and we’ll tell you that on the call before anyone drives out.
