Genie cable and drum replacement in Alpharetta typically costs $130 – $250 installed, parts included, and we carry the common sizes on the truck so the work gets done in one trip. You’ll usually discover the problem the hard way: a loud snap or pop, then one side of the door hangs crooked and refuses to lift. That’s the lifting cable letting go, and the drum above it has usually been chewing itself up for months before the failure.
We work on Genie systems across Alpharetta every week, from Windward to Crabapple. The good news: this is a repair we can usually complete the same day you call, because the failure is loud, visible, and easy to confirm when we walk up to the door.
Which Genie Models This Applies To
Genie has been making residential garage door hardware for decades, and the cable and drum setup varies by series. The IntelliG, TriloG, and ReliaG lines all use torsion spring systems where the lifting cables wrap around machined aluminum or steel drums mounted on the spring shaft. If your door has a torsion spring above it, this is the system we’re talking about.
Here’s the compatibility gotcha most homeowners don’t know: the drum isn’t universal. Genie uses specific drum profiles, and the cable length is matched to your door height and drum circumference. A drum from a 7-foot door won’t work right on an 8-foot door, and vice versa. We identify the right part by reading the labels on the spring shaft or measuring the drum diameter and cable length directly. In Alpharetta, humidity and temperature swings harden and fray cables faster than the national average, so we see more cable failures here than in drier climates.
We’re an independent service provider, not affiliated with Genie, but we stock Genie-compatible OEM and quality aftermarket components. For most homeowners, a quality aftermarket drum and cable set does the job every bit as well as OEM at a lower installed price. When we do use aftermarket parts, they’re sourced from suppliers we’ve run on hundreds of doors, not whatever’s cheapest on a shelf somewhere.
Styles & brands we work with






Signs Your Genie Cable Is Failing
- Visible fraying or broken strands. If the cable looks like a rope that’s starting to unravel, it’s past time to replace it. Those strands are load-bearing; when enough let go, the remaining steel can’t hold the door.
- The door hangs crooked or jerks while moving. One cable is carrying more weight than the other. That uneven load strains every moving part and will eventually yank the drum out of alignment.
- A screeching or grinding sound near the top of the track. The drum is scored or the bearings are worn. Each cycle grinds it a little worse, and the damage accelerates fast.
- The door comes down too fast, then slams or rebounds. This one is urgent. It usually means a cable has snapped and the door is no longer controlled. Don’t keep operating it.
- You hear a pop and the door won’t move at all. The cable snapped completely. This is the moment you call, because continuing to use the opener can bend the track and turn a cable job into a track replacement.

AfterReplacement Cost & What’s Included
Plan on $130 – $250 for a complete Genie cable and drum replacement in Alpharetta, installed. The range comes down to a few things: whether one or both cables are being replaced, the drum condition (if the drum is scored, it goes too), and whether we need to rebalance the torsion spring as part of the job.
We always replace cables in pairs. If one side has failed, the other is the same age, the same material, and has been under the same load. Doing both keeps the door lifting evenly and prevents a second failure within weeks. That’s included in the price, not an add-on.
Every quote is in writing before we unbolt anything, and the number you approve is the number on the invoice. Your repair is covered in writing for 365 days. If it fails in that window, we return at no charge. That’s the guarantee on every job we run in Alpharetta, and it’s part of how we work under the Garrison Standard.
DIY or Call Us?
Here’s the honest split. You can safely eyeball the cables and drums from the ground: look for fraying, check if one side of the door sags, and note any grinding sounds when the door moves. That’s good information to have. What you shouldn’t do is remove or loosen anything on a torsion spring system. The spring is under hundreds of pounds of rotational force, and if it lets go while you’re on a ladder, the result can be serious injury or worse.
We see this exact scenario a few times a year in Alpharetta: a homeowner tries the YouTube shortcut, the spring unwinds while his hand is on the winding bar, and now he’s calling us for a bigger job than the one he started with. Don’t be that guy. Call us at (229) 404-6747. Wade Mercer and his crew handle cables and drums the same way we handle every job: diagnose it straight, quote it in writing, fix it right, and stand behind it for a year.
FAQs
A standard two-cable, two-drum replacement on a residential Genie door takes about 60 to 90 minutes once we’re on site. We carry the common sizes in the truck, so we’re usually done in one visit. Some older Genie models with nonstandard drums may need a parts order, which adds a day or two.
No. A spliced or clamped cable is a cable that will fail again, and when it fails, the door can come down uncontrolled. We replace cable and drum assemblies together when either is worn; it’s the only way we’ll stand behind the work for 365 days. Call (229) 404-6747 and we’ll tell you exactly what your door needs.
Yes. Our trucks carry the most common Genie drum profiles and cable lengths for 7-foot and 8-foot doors, which covers the large majority of homes in Alpharetta. If your model takes a less common spec, we’ll verify it and have the right part in hand before the return visit.
Most failures come down to age and moisture. In Alpharetta, humid summers accelerate rust and strand fatigue on cables that are seven years old or more. A misaligned or worn drum adds friction, which speeds things up. We’ll check the drum alignment and spring balance during the replacement so the new cables aren’t set up to fail the way the old ones did.
