Genie Cable & Drum Replacement: The Alpharetta Owner’s Guide
If you’re searching for Genie cable and drum replacement in Alpharetta, the direct answer is this: we stock Genie-compatible cables, drums, and the related hardware on our trucks, and a complete cable and drum replacement on a Genie door typically runs $130 to $250 installed, depending on whether it’s one side or both. Most Alpharetta homeowners discover the failure the same way: the door won’t lift evenly, one corner dips, or there’s a loud snap followed by a door that’s suddenly stuck. The cable is the braided steel line that runs from the bottom of the door up around the drum, which is the barrel-shaped spool at the top of the torsion assembly that winds and unwinds the cable as the door moves.
Here’s what matters and what we’ve learned working on Genie doors across Alpharetta since 2015. Marcus Deller, our owner, started in this trade because he wanted work where you could see the problem, fix it, and test it before you left. That’s how we approach every cable and drum job: name the part, quote the number, then we decide.
Which Genie Models This Applies To
The cable-and-drum assembly on a Genie door is more standardized than people assume, but there are two real compatibility points that matter. The first is the drum diameter. Most Genie residential doors use a 4-inch drum, but economy Genie models from the 2000s occasionally shipped with a 3-inch drum, and if you pair the wrong drum with your existing cables, the door lifts crooked within a week. The second is cable length, which is set by your door height, not the opener. A 7-foot door and an 8-foot door take different cables, and even a six-inch difference changes how the door sits at the top of its travel.
We work on the full Genie residential line: Pro Series, IntelliG, SilentMax, and the builder-grade ReliaG models installed in a lot of Alpharetta subdivisions built between 2000 and 2015. Servo Garage Doors Alpharetta is an independent service provider, not affiliated with Genie or The Genie Company. That matters because it lets us stock both true Genie OEM parts and quality aftermarket equivalents without pressure to steer you one way. For Genie specifically, we recommend OEM drums on any door with a Genie-branded torsion assembly; the aftermarket drums are fine on the cable side, but the hub taper on Genie torsion tubes is slightly different from the generic hardware, and that’s a tolerance worth respecting.
Signs Your Genie Cable & Drum Replacement Is Failing

This failure is rarely silent. Here are the five symptoms we see most often on service calls across Alpharetta, from Crabapple to the Windward corridor:
- The door lifts crooked or one side sits lower than the other. This is the number one sign. The cable on one side has either stretched or is about to let go, and the drum is no longer winding both sides evenly.
- A visible fray or broken strand on the cable. Genie factory cables are 1/8-inch 7×19 aircraft-grade steel, and when you can see individual strands poking out, the cable’s strength is down substantially. It is not going to re-braid itself.
- A snapping sound followed by the door slamming to one side. That is a full cable break. The door is now hanging on one cable and the roller channels, and continuing to run the opener while it’s like this bends the panel and damages the track.
- Gouging or scoring on the drum face. When the cable jumps the groove, the drum edge chews the steel, and once a drum face is scored, a new cable fails prematurely on the rough spot within months.
- The cable is no longer seated in the drum groove, or it’s wound over itself. This is called cable overlap, and it changes the effective drum diameter on one side, which makes the door lift unevenly until the cable snaps under load.

AfterReplacement Cost & What’s Included
In Alpharetta, a Genie cable and drum replacement runs $130 to $250 installed. The low end covers one cable and one drum on a standard 7-foot door with the torsion hardware already in good shape. The high end covers both cables and both drums on an 8-foot or heavyweight door, including shimming the torsion assembly so it sits true before tensioning adjusts. Every price is flat and written before the first fastener turns; that is Clause 1 of The Haven Standard, and it means the quote you see is the invoice you pay.
Here’s the cost breakdown so you know exactly what you’re paying for:
- Genie-compatible cable (7-foot door): $15-$35 each
- Genie-compatible cable (8-foot door): $20-$45 each
- Drum, 4-inch or 3-inch, Genie-compatible: $25-$60 each
- Labor, both sides, including tension setup and balance test: $75-$120
- Documented photo record of the work: included on every visit, per Clause 4 of The Haven Standard
Our 365-Day Done Right Promise applies to every cable and drum replacement. If the repair isn’t right, we make it right. And if you have a written estimate from another Alpharetta company, bring it; we’ll give you a free second opinion and our own flat price.
DIY or Call Us?

We’ll be straight with you. The garage door torsion assembly is the one component on a house that will hurt you without meaning to. A torsion spring under tension holds enough stored energy to break bone, and when a cable snaps, that energy releases instantly. Replacing a cable or drum yourself requires unwinding the torsion spring with two winding bars, which is not a beginner task. If you’re not trained on torsion systems, this is the one repair where we tell you plainly: call us at (678) 679-2096.
What you can safely do is inspect the door from the inside while it’s closed. Look at both cables where they wrap the drums, check for fraying where the cable enters the bottom fixture, and photograph anything that looks wrong. That photo is genuinely useful; send it to us or have it ready when our technician arrives, and it establishes the same baseline we document ourselves. We do same-day cable and drum replacement in Alpharetta on most calls, because the parts are on the truck and the job takes about an hour.
FAQs
On a Genie door in Alpharetta, factory cables typically last 8-12 years, but the Georgia heat shortens that in unconditioned garages. The cables are steel, but the torsion assembly expands and contracts with every season, and that slow cycling wears the cable at the drum groove and at the bottom fixture loop. If your door is over 10 years old and you’ve replaced the springs once, plan on replacing the cables and drums as a set with the next spring change. Call (678) 679-2096 and we’ll quote a flat price while we’re already at the house.
No, and we don’t. A frayed or broken Genie cable cannot be safely spliced, welded, or rewound. The steel has already failed, and any repair that reuses a damaged cable is a liability we won’t put on your door. The replacement cable is the correct fix, and it’s a $15-$45 part, so it’s rarely the part of the repair worth economizing on. We’ll show you the failed cable and the new one side by side before we install it; that photo documentation is part of every visit.
On a standard Genie door, replacing both cables and both drums takes 45-75 minutes in Alpharetta, including unwinding and retensioning the torsion spring, setting the drum heights, and running the door through five full cycles to verify balance. If we find the spring is also failing, add 30 minutes and the spring repair price range is $180-$340. We carry the cables, drums, and springs on the truck, so there’s no second appointment needed.
Yes. Our trucks carry Genie-compatible 4-inch and 3-inch drums, 7-foot and 8-foot cables in both 1/8-inch and 3/32-inch gauges, and the bottom fixture hardware that connects the cable to the panel. We also stock parts for LiftMaster and Chamberlain openers, so if the opener side of the job needs attention, we handle it in the same visit without a second dispatch fee. Name the part. Quote the number. Then we decide.
If your Genie cable or drum has already failed, or you’re seeing the warning signs and want a flat written price before anything gets touched, call us at (678) 679-2096. Live person, 24/7, no recorded trees and no callback window. We’ll give you the price range on the phone, send a technician with the parts, and you’ll have a documented photo record of everything we found and everything we did before we leave the driveway.
