We stock and install Amarr cable and drum replacement parts right here in Marietta, and in most cases we can complete the job the same day for $130 to $250. The cables and drums work together as a pair: the torsion tube runs through the center of both drums, and each cable spools onto its drum to lift and lower your door evenly. When one side fails, you’ll notice it immediately by the door hanging crooked, a loud snap followed by a slamming door, or cables that look frayed and unraveling when the door is open.
Almost every Amarr door in Marietta and East Cobb uses the standard torsion system, which means we carry the right drum profiles and cable lengths on the truck for the vast majority of service calls. Aaron Teague and our crew have replaced cables on everything from older Amarr Heritage series doors to newer Classica and Stratford models, and we can confirm the difference between the 4-inch and 6-inch drums usually takes about five minutes to identify once we’re looking at the door.
Which Amarr Models This Applies To
This applies to virtually every Amarr residential door built with a torsion spring system, which includes the Heritage, Classica, Stratford, Hillcrest, and Lincoln series. The critical compatibility detail is the drum size and the cable length, both of which are determined by your door’s height and weight, not by the series name stamped on the panel. Amarr doors are rated by door height, and a 7-foot door uses a different drum and cable set than an 8-foot door, even if the two doors look identical from the outside.
The surest way to match the part is to check the label on the door edge near the bottom panel, which lists the door model and size. If that label is gone, we measure the drum diameter and cable length on site. For the cable and drum replacement, we use either Amarr OEM parts or high-grade aftermarket equivalents that meet the same torsion and tensile specs. The OEM versus aftermarket question on Amarr doors is straightforward: the OEM parts are an exact match, but quality aftermarket cables and drums typically cost 15 to 20 percent less and perform identically. We stock both and will always tell you the difference so you can choose. We are an independent service provider, not affiliated with Amarr, and we service LiftMaster, Chamberlain, and Genie openers alongside Amarr doors.

Signs Your Amarr Cable & Drum Replacement Is Failing
- Door hangs crooked when opening or closing. One cable has stretched, slipped, or broken, and the drum on that side is no longer taking up slack. The uneven lift puts immediate strain on the opposite cable and the torsion spring.
- Frayed or unraveling cables with the door open. Amarr cables are 3/32-inch aircraft-grade steel, and in Marietta’s humid summers, the cable near the bottom bracket is the first place rust and wear show up. You’ll see individual strands breaking apart before the cable gives completely.
- Loud snap followed by the door slamming down. That’s a broken cable giving way entirely. Do not try to open the door by hand after this. The spring still holds tension, and the remaining cable is now bearing double the load it was designed for.
- Grinding or scraping sound during operation. A worn drum with a rough groove will chew through the cable as it spools, leaving visible metal dust on the door tracks or floor. This is a drum failure, not just a cable problem, and both need to be replaced together.
- Door jerks or shudders partway up the track. The cable is catching on the drum, sometimes from a kink, sometimes from a bent drum flange. Every jerk stresses the spring, the hinges, and the opener’s travel module.
Replacement Cost & What’s Included
For Amarr cable and drum replacement in Marietta, you’re looking at $130 to $250 installed, with most jobs landing in the $160 to $200 range for a single door. The spread comes down to a few factors: door height (8-foot doors cost more because the cables are longer and the drums are deeper), whether one or both drums need replacing, and whether we’re working with OEM or aftermarket parts on the drum set.
Every quote from us includes the parts, the labor, and the written guarantee before a single bolt is turned. Here’s the breakdown:
- Cable replacement only: $130 – $180
- Cable plus one drum: $150 – $220
- Cable plus both drums: $180 – $250
- 8-foot door adjustment: add $20 – $40
The price you’re quoted is the exact price you pay. No surprises written in after the fact, ever, and that includes the 365-Day Done Right Promise: if anything fails within 365 days, we come back and fix it at no charge.

Every Amarr door with a broken cable still has a fully loaded torsion spring, which can hold hundreds of pounds of stored force. If that spring unwinds while the door is partially open and the cable is off the drum, the spring and the winding cone become a projectile. We say this not to scare you, but because it is the single most common way homeowners end up in the emergency room with an injury a professional never would have had.
What you can safely do is unplug the opener, keep kids and pets away from the door, and close the door if it will move smoothly without force. Then call us. We’ll have the truck loaded with Amarr-specific cable and drum options before we leave, and the repair itself typically takes 45 to 75 minutes on site. Call (762) 209-3693 and we’ll talk through what you’re seeing.
FAQs
On a properly maintained Amarr door in the Marietta climate, cables and drums typically last 10 to 15 years. Heat, humidity, and infrequent lubrication shorten that lifespan, especially in homes near the Chattahoochee where moisture sits on the metal. Annual inspection and lubrication will usually nearly double the life of the cable set. Call (762) 209-3693 if you can’t remember the last time the door was serviced.
With cables, replacement is the only safe option. Once the strands begin separating inside the braid, the cable has lost a measurable portion of its working strength, and every cycle with the spring loaded brings it closer to a complete break. We don’t sell or install “patched” cables for good reason: the labor is the same either way, and a new set locks in the full lifespan. The replacement is quick and comes with our 365-day warranty.
Most Amarr cable and drum replacements take 45 to 75 minutes once the tech starts work. That includes unwinding and rewinding the torsion spring, removing the old drums and cables, setting the new parts, and testing the balance and travel on the door. We also inspect the opposite cable and the spring while we’re in there, because a door that’s eaten one cable has usually stressed everything else on the torsion tube.
We stock Amarr-standard drum sets and cable lengths on every truck, including both 4-inch and 6-inch drum profiles and cable sets for 7-foot and 8-foot doors. In the rare case of a non-standard door or an unusual hardware configuration, we can have the specific part from our supplier the same afternoon in most of Marietta. You’ll know before we start work either way.
