Raynor Cable & Drum Replacement: The Van Nuys Owner’s Guide
Raynor cable and drum replacement in Van Nuys typically runs $130-$250 installed, and our trucks carry the drums, cables, and hardware needed for most Raynor residential models on the same day. The job itself takes about an hour on a standard 7-foot door once we’re on site. Most homeowners discover the problem when they hear a sharp snap from inside the garage, or when they notice one side of the door sitting visibly higher than the other.
The cable and drum work together as a pair: the drum is the grooved wheel mounted above the door on the torsion tube, and the cable winds onto it as the door lifts. When one side lets go, the door doesn’t just sag, it puts uneven tension on every other component. In Van Nuys, where garage doors get cycled year-round with no real winter shutdown, we see cables fray to the snapping point more often than in colder climates where doors get seasonal rest.
Which Raynor Models This Applies To
This replacement covers Raynor residential sectional doors from the mid-1990s forward, including the Aspen, AP, and Centura series, plus the newer Prodigy and Aluma lines. The parts that matter are the lift cables, the cable drums, and the retaining hardware at the bottom bracket. Raynor uses two dominant drum profiles: a 4-inch drum on standard 7-foot doors and an extended 5-inch drum on 8-foot doors. The cable length follows the door height directly: 7-foot doors use roughly 8-foot, 7-inch cables, and 8-foot doors run closer to 10 feet.
The identification short version: look for the manufacturer sticker on the inside of the door section or on the end bearing plate. If the sticker is gone, we measure. The drum diameter and the cable length are checkable in about two minutes. Servo Garage Doors Van Nuys is an independent service provider, not affiliated with Raynor, which means we’re not locked into a single parts source. For this part specifically, we stock both OEM-spec and quality aftermarket equivalents that match the original drum profile and cable length. The aftermarket option typically shaves $20-$40 off the installed price with no sacrifice in longevity.
Signs Your Raynor Cable & Drum Replacement Is Failing

- The door is visibly crooked or sits higher on one side. One cable has likely slipped or snapped, and the remaining cable is doing the full lifting load. Doors run this way for weeks; it’s the tension imbalance that kills the other components.
- A frayed cable, especially near the bottom attachment bracket. You’ll see individual wire strands separating anywhere along the cable’s length. Once you can count broken strands without touching anything, the cable is past its service life.
- The door jerks or shudders on the way up. This usually means the cable has jumped a groove on the drum. The drum keeps spinning out of sync, and each pass scores the cable surface a little deeper.
- A visible gap or slack in one cable while the door is closed. A seated cable should be taut. Slack at rest means the cable has hopped the drum and is no longer tracking in the groove. It will get worse every cycle.
- Scraping or grinding from the drum area. The cable is dragging against the bearing plate or the drum edge because the drum has shifted on the torsion tube, which is a sign of a worn or loosened drum set screw.

AfterReplacement Cost & What’s Included
Raynor cable and drum replacement in Van Nuys runs $130-$250 installed. The range exists because some jobs require one cable only, some require both drums and both cables, and some require a new bottom bracket. We break the quote into parts and labor separately, on paper, before anything is touched. That’s Clause 1 of The Haven Standard: a flat, written price and written scope delivered before any work begins. ‘Call for a quote’ has never been how this shop operates.
The written quote includes the parts match to your door’s drum profile and cable length, replacement hardware, and the labor to install and re-balance. It also includes something most companies won’t put in writing: a photo record. We photograph the failed component before quoting (Clause 4 of The Haven Standard), then photograph the completed work before we leave. You get both. The installation is covered by the 365-Day Done Right Promise: if the repair is not right, we make it right.
DIY or Call Us?

The honest split is this: you can safely inspect, and you should not replace. Inspection means looking at the cables closely, noting where the fray is, and checking whether the drum is seated. That’s all no-tool work. Replacement is different. The cables and drums live on the same torsion tube as the spring, and the spring is under tension even with the door open. One incorrect move at the drum set screw can release that tension unpredictably. We treat this as a professional-only repair, and we say so plainly. The risk isn’t worth the $200 saved.
If you live in Van Nuys or nearby and you’re seeing any of the symptoms above, call (213) 418-2520. You’ll get a live person, a named technician with an on-the-way text, and a written price before any work starts. We quote parts up, labor separately, and leave you with documentation, not a story.
FAQs
Around 7 to 12 years in Van Nuys, depending on cycle count and exposure. Doors near the 405 corridor and Van Nuys Airport see more airborne grit, which accelerates cable wear. A door cycled 4-5 times daily will beat that estimate down toward 7 years.
No, a frayed cable is past the point of safe service. Patching or splicing a garage door lift cable is not a practice we perform or recommend. The cable is replaced, and the adjacent drum and bracket are inspected at the same time. Call (213) 418-2520 for the exact range for your door.
About an hour on a standard 7-foot Raynor door, once the technician is on site. Doors with rusted hardware or extended-height setups may push closer to 90 minutes. We quote the exact labor before we start, and the price doesn’t change once we see the door.
Yes. Our Van Nuys trucks carry both Raynor drum profiles (4-inch and 5-inch), standard 7-foot and 8-foot cable lengths, and the necessary replacement brackets. If your Raynor model needs a specialty part we don’t stock, we’ll tell you before any work is scheduled, not after we arrive.

Raynor cable and drum replacement isn’t a job to postpone. The moment one cable fails, the whole door runs out of balance, and every cycle adds strain to the remaining cable, the rollers, and the spring itself. We make the fix straightforward: a flat written quote, parts and labor separated, a photo of the failed component before anything comes off, and an installed price you’ll see before a single bolt is touched. Call (213) 418-2520 for a free estimate.
