Genie Cable & Drum Replacement: The Westminster Owner’s Guide
Genie cable and drum replacement in Westminster typically runs $130 to $250 installed, and we carry Genie-compatible cables and drums on our trucks for same-day service in most cases. You’ll usually discover the problem two ways: the door hangs crooked or jerks on the way up, or you hear a snap and find a frayed cable dangling near the track. Either way, the fix is straightforward when the right parts go on, and we quote the exact price in writing before any work begins.
Most Westminster homeowners we serve in neighborhoods like Bradburn Village and Countryside first notice the issue when one side of the door sits higher than the other. That’s the cable telling you something. The drum, which is the grooved spool that winds the cable as the door moves, rarely fails on its own. Usually it’s the cable that gives out first and takes the drum’s surface with it, or the drum’s set screws loosen over time and let the cable walk off the groove entirely.
Which Genie Models This Applies To
Genie uses a few cable and drum configurations across its residential line, but the most common setup on doors from the last 15 years is a 7-foot or 8-foot torsion spring system with 1/8-inch or 5/32-inch aircraft-grade cable. The IntelliG, TriloG, and legacy PMX series all use variations of this, and the drum size changes based on door height and weight. An 8-foot door needs a taller drum than a 7-foot door, and that’s a compatibility gotcha that gets missed more often than you’d think. The wrong drum means the cable stacks unevenly and the door binds within a few cycles.
To identify what you need, look at the label on the inside of the door panel. Genie stamps the model name there, usually near the top section or on the end stile. If the label’s gone, we measure the drum’s outside diameter and the cable’s wire diameter on site. We stock OEM Genie cables and drums plus quality aftermarket equivalents that match the original spec. For Genie specifically, the aftermarket cables from Action Industries hold up well and cost a bit less than OEM, but on heavier doors we prefer the Genie-branded part. We’ll tell you which way we’d go and why, and the written quote shows both options when it makes sense.
One thing worth knowing: Servo Garage Doors Westminster is an independent service provider. We’re not affiliated with Genie. We work on Genie doors every week, and we buy the parts from the same supply chains any authorized dealer uses. The advantage is that we don’t have a brand quota to hit, so the recommendation on OEM versus aftermarket is based on your door, not a sales target.
Signs Your Genie Cable & Drum Replacement Is Failing

- The door tilts to one side when opening or closing. This is the most common early sign. One cable has stretched or started to fray while the other still holds, so the door lifts unevenly. Left alone, the frayed cable snaps and the door can slam down hard on one side.
- A visible fray or broken strand near the bottom fixture. Genie cables attach to the bottom corner bracket with a loop and a crimped ferrule. That crimp is the first thing to corrode in a Westminster garage, especially one that sees road salt drip off cars all winter. Once one or two strands separate, the cable is done.
- The cable has come off the drum and is wrapped around the torsion shaft. This happens when a drum’s set screws loosen. The cable walks off the groove, winds around the bare shaft, and the door stops mid-travel or drops suddenly when the spring tension shifts.
- You hear a popping or clicking sound from above the door during operation. That’s the cable skipping across a worn drum groove. The groove’s edges get chewed up over time, and instead of seating cleanly, the cable pops in and out under tension. It’s loud enough to hear from inside the house.
- The door stops about a foot from the floor and won’t close the rest of the way. When a cable jumps the drum, the door binds on the track and the opener’s force sensor reverses it. Forcing it down with the opener button is how doors get pulled off their tracks entirely, and that turns a $130 cable job into a $600 track and panel repair.
Before
AfterReplacement Cost & What’s Included
In Westminster, Genie cable and drum replacement runs $130 to $250 installed, and that includes both cables and both drums replaced as a set. Replacing one side only is false economy. The un-replaced side has the same wear history as the one that failed, and you’d be back in the same garage within a year for the same repair on the other side. We replace both sides every time.
What drives the range is door height and whether the drums are standard or high-lift. A standard 7-foot door with standard drums sits at the bottom of the range. An 8-foot door or one with high-lift track needs larger drums and more cable, which pushes the price toward the top. The written quote you receive before any work starts shows parts and labor as separate line items, so you see exactly what you’re paying for. Every cable and drum replacement carries our 365-Day Done Right Promise: if it’s not right, we make it right, backed by The Haven Standard and a terms page, not a handshake.
DIY or Call Us?

We’ll be direct about this: cables and drums carry full torsion spring tension, and releasing that tension wrong is how people lose fingers and break jaws. The spring on a Genie door holds enough stored energy to lift a few hundred pounds. If you don’t have the winding bars and the experience to release and rewind that spring safely, do not attempt this repair yourself. That’s not scare tactics, it’s the same advice every door tech gives their own family.
What you can safely check is whether the cable is visibly frayed and whether the door is binding. Take photos. Then call us at (720) 807-1427. We’ll quote the repair over the phone, send a technician who photographs the failed part before quoting a replacement per Clause 4 of The Haven Standard, and the written price you get is the price you pay. Name the part. Quote the price. Then fix it.
FAQs
Genie cables and drums typically last 7 to 10 years in Westminster, and in our experience on the Front Range, the cable fails first. Colorado’s dry air keeps rust at bay, but the temperature swings between winter nights and summer afternoons put constant expansion stress on the cable’s crimped ends, which is where most failures start. If your door is over 8 years old and you’re seeing fraying, replace the set before it snaps under load.
No. A frayed cable cannot be spliced or repaired safely. Once strands separate, the cable’s load rating drops well below what the door needs, and the failure is imminent. The only correct fix is a new cable, and we always replace both sides and both drums together. Call (720) 807-1427 and we’ll confirm the price before we even schedule the visit.
A standard Genie cable and drum replacement takes 60 to 90 minutes from start to finish. That includes releasing spring tension, swapping both cables and drums, rewinding the spring, and testing the door through a full open-close cycle. Most Westminster customers have the work done the same day they call, and the technician leaves a documented photo record of what was found and what was installed.
Yes. We stock Genie-compatible cables and drums for 7-foot and 8-foot doors on every truck, covering the models most common in Westminster homes. If you have a high-lift setup or a less common Genie configuration, we can source the part within one business day. Call (720) 807-1427 with your model number handy and we’ll confirm availability on the spot.
