Amarr Cable & Drum Replacement: The Arlington Owner’s Guide
Amarr cable and drum replacement in Arlington typically runs $130 to $250 installed, and we stock the common Amarr-spec cables and drums on our trucks so most jobs are done in a single visit. You’ll usually discover the problem when the door hangs crooked on one side, makes a grinding noise near the top of the track, or refuses to open all the way because one cable has jumped the drum and wrapped around the shaft. The cable and drum work as a matched pair on torsion-spring doors: the drum winds the cable as the door moves, and when one side fails, the whole system fights itself.
We’re an independent service provider, not affiliated with Amarr, but we work on their doors every week across Arlington, Dalworthington Gardens, and Pantego. The photo record we hand you before quoting is the same one Marcus Deller, our owner, built the company on: you see the frayed cable and the grooved drum before you approve a dollar of work.
Which Amarr Models This Applies To
Amarr builds their residential lines under a few series names you’ll recognize: Heritage, Classica, Stratford, Oak Summit, and Lincoln. All of them use a torsion spring assembly when they’re fitted with standard lift, and that’s where the cable and drum live. The part compatibility comes down to two measurements: cable length (usually 8’6″ or 12’6″ for a 7-foot or 8-foot door) and drum diameter (typically 4 inches for residential doors).
The compatibility gotcha with Amarr is this: their newer doors shipped after roughly 2018 use a 5/32-inch aircraft-grade cable as standard, while older builds and some builder-grade Heritages used a thinner 1/8-inch cable. You can’t tell by looking at the door. You measure the cable diameter with a caliper or read the drum’s stamped part number. We carry both diameters, plus aftermarket drums from DURA-LIFT and Coupler that cross-fit Amarr’s standard 4-inch drum profile at a lower cost than OEM. For most Arlington homes, a quality aftermarket drum paired with a new 5/32-inch cable is the right call: same lifespan, less money. If you want OEM Amarr parts specifically, we can order them, but the lead time is usually 5 to 7 business days rather than same-day.
Signs Your Amarr Cable & Drum Replacement Is Failing

- The door hangs uneven or sits crooked in the opening. One cable has stretched or begun to fray, which means one side of the door is carrying more tension than the other. The drum on that side often shows visible grooves where the cable has been sawing into it.
- You see a cable dangling, unwound, or wrapped around the shaft. This usually happens after a cable jumps the drum because the door was forced open while the spring was broken, or because the drum’s cable track wore down enough to lose its grip.
- A grinding or scraping sound near the top of the door during operation. The drum is running metal-on-metal against the shaft or the cable is rubbing the header. In Arlington’s summer heat, lubrication breaks down faster and this sound gets louder before the part fails completely.
- The door opens farther on one side than the other, then stops. A cable that’s lost a few strands will wind unevenly on the drum. Each cycle makes the discrepancy worse until the door binds in the track.
- You find loose strands of wire on the floor or on the track. A fraying cable doesn’t fail silently. If you’re seeing wire strands anywhere near the door, the cable is already failing, and the remaining strands are carrying more than they’re rated for.

AfterReplacement Cost & What’s Included
In Arlington, a cable and drum replacement on an Amarr door runs $130 to $250 installed. That’s the flat price you’ll get in writing before we touch the door, per Clause 1 of The Haven Standard. The range is driven by three things: cable diameter (5/32-inch costs slightly more than 1/8-inch), whether one or both drums need replacing, and whether the door is standard lift or high lift, which requires a different drum profile.
Every replacement includes the parts themselves, removal of the old cable and drum, installation and balancing of the new pair, lubrication of the shaft, and a documented photo record of the failed parts and the completed work, which you get before we leave. The labor warranty is covered under our 365-Day Done Right Promise: if something isn’t right, we come back and make it right. If you’re holding a written estimate from another company for the same work, bring it in. We’ll give you a Free Second Opinion on the paperwork.
DIY or Call Us?

We’ll be honest with you about this one: this is not a safe DIY job. The cable and drum are under full torsion spring tension. If you remove a cable or unbolt a drum without properly releasing that tension, the drum can spin violently and the cable can whip. We’ve seen the aftermath of internet-tutorial repairs in Arlington garages, and the injury risk is real. What you can safely do is inspect: look for rust on the drum, count the loose strands on the cable, and watch whether the door moves evenly. Write down what you saw, then call us.
Marcus Deller likes to say the quiet part out loud: “Name the part. Quote the price. Then fix it.” That’s the whole job, and we’ll give you the written number before anything comes off the wall. Call (682) 452-1782 for a free estimate, or describe what you’re seeing and we’ll tell you straight whether it’s a cable and drum replacement or something simpler.
FAQs
Amarr cables and drums typically last 8 to 12 years on a door that’s cycled twice daily, but North Texas heat and humidity can shorten that to 6 or 7 years because the cable’s galvanized coating degrades faster and the drum’s aluminum oxidizes sooner. If your door is over 10 years old and you’re seeing any of the signs above, it’s time to plan for replacement rather than waiting for the snap.
No, and we won’t take your money to try it. A frayed cable has already lost its rated strength, and a drum with worn tracks can’t be machined back to tolerance. The repair is replacement, which is why our Arlington price is predictable and why we stock the common Amarr sizes on the truck. Call (682) 452-1782 and we’ll confirm the measurements before we dispatch.
Most Amarr cable and drum replacements take 45 to 90 minutes on site, assuming the springs are healthy and only the cable and drum need work. If the torsion spring is also failing, we’ll address that in the same visit and give you the combined written price before any work starts.
Yes. We carry 8’6″ and 12’6″ cables in both 1/8-inch and 5/32-inch diameters, plus 4-inch drums in the standard lift profile that matches Amarr’s Heritage, Classica, Stratford, Oak Summit, and Lincoln lines. We also keep parts for LiftMaster, Chamberlain, and Genie openers in the truck, because the door and the opener often need attention at the same time. If your door needs something we don’t have on board, we’ll give you the written price before we leave, not a callback window.
