AfterGenie Cable & Drum Replacement: The Hollywood Park Owner’s Guide
Genie cable and drum replacement in Hollywood Park typically runs $130-$250 installed, and we stock the common Genie drum sizes and cable lengths on our trucks for same-day completion. Most Genie screw-drive and chain-drive opener systems paired with sectional doors use either a 4-inch or 5-inch diameter drum with 1/8-inch or 5/32-inch aircraft-grade galvanized cable, depending on door height and weight. If your door is hanging crooked, cables are frayed near the bottom bracket, or the drum has chewed grooves into the cable, the assembly needs attention before it fails completely.
Homeowners in Hollywood Park usually notice the problem when the door starts closing heavier on one side, or they spot a cable unspooled and dangling beside the track. The Texas heat cycle, hard water mineral buildup on the cable, and the limestone dust that blows through this part of Bexar County all shorten the service life. We see it often enough near Bitters Road that our trucks carry the full Genie-compatible range.
Which Genie Models This Applies To
Genie has used several drum and cable configurations across its opener lines, and matching the right assembly matters. The screw-drive models, including the Excelerator and IntelliG series, typically pair with 4-inch drums on 7-foot doors and 5-inch drums on 8-foot doors. Chain-drive units like the ChainLift and ReliaG lines use similar drum sizing but may have different cable anchor points at the bottom bracket. The direct-drive models, including the SilentMax and TriloG series, sometimes use a proprietary drum hub that requires the OEM part rather than an aftermarket equivalent.
To identify what you need, check the label on the opener rail or motor housing for the model number, then measure your drum diameter and count the cable strands at a frayed section. A 7 x 7 strand count is standard for residential Genie systems; 7 x 19 is heavier duty and used on wider doors. We carry both OEM Genie drums and quality aftermarket equivalents from DURA-LIFT and Prime-Line that meet the same tensile specs. The aftermarket drums save twenty to thirty dollars and carry the same 90-day coverage under our promise. One compatibility gotcha: the Excelerator II uses a drum with a slightly deeper cable groove than the original Excelerator, and swapping them causes uneven winding. We verify the part before we leave the shop.
Signs Your Genie Cable & Drum Replacement Is Failing
- Door hangs crooked or one side drops faster. When one cable frays and stretches more than its mate, the drum pulls unevenly. The door tilts in the frame and the rollers start binding in the track. In Hollywood Park, we see this most often on north-facing doors where morning condensation corrodes the cable faster.
- Frayed or rust-speckled cable near the bottom bracket. The cable flexes most where it wraps around the drum and again where it anchors at the bottom fixture. Rust blooms at these stress points first, and once you see three or more broken outer strands, the cable is living on borrowed time.
- Grinding or clicking from the drum area during open/close. A cracked drum hub lets the cable seat unevenly, creating a rhythmic click as each revolution passes the flaw. The noise is the drum telling you it is shaving metal off itself.
- Cable unspooled and tangled beneath the drum. This happens when the set screw loosens or the drum splines strip. The cable drops in a heap, the door goes slack on that side, and the opener strain mounts fast. Do not run the opener again until it is fixed.
- Door feels heavier than usual or the opener labors. A properly wound cable and drum assembly carries the door weight in balance. When one side loses tension, the opener picks up the slack and the motor overheats. We have replaced openers in Hollywood Park that failed only because a cable issue was ignored too long.
Replacement Cost & What’s Included
| Service | Hollywood Park Price Range |
|---|---|
| Cable & drum replacement (single side) | $130-$190 |
| Cable & drum replacement (both sides) | $180-$250 |
| Additional bottom bracket replacement (if corroded) | $40-$75 |
The range depends on door height, drum size, and whether the bottom brackets need replacement too. A standard 7-foot single-car door with 4-inch drums and no bracket corrosion lands at the lower end. An 8-foot door with 5-inch drums, both sides, and seized hardware runs higher. We state the flat price before touching a tool. Parts, labor, lubrication, and safety check are all included. The 90-Day Done Right Promise covers the work in writing. If the cable does not run true or the door balance is off, we come back. No paperwork to file, no argument.

DIY or Call Us?
There is a safe middle ground here. You can inspect the cable for fraying and check whether the drum set screws are tight with the door fully closed and the opener disconnected. What you should not do is loosen a drum with the door under spring tension. The torsion spring above the door stores enough force to cause serious injury if the cable slips or the winding bar kicks back. We have seen homeowners in Hollywood Park try to reseat a cable with the door partially open, and the result is a bent top section or worse.
If the cable is simply off the drum and the spring system is intact, a trained technician can re-tension and reseat it in twenty minutes. If the drum is cracked or the cable is frayed, replacement is the only sound fix. We carry the parts, we quote upfront, and we finish in one visit. Call (830) 356-2849 when you are ready.
FAQs
In this climate, eight to twelve years is typical for cables, twelve to fifteen for drums. Hard water mineral deposits and limestone dust accelerate corrosion, so doors near construction or unpaved alleys tend to run shorter. Annual lubrication of the cable and drum groove adds two to three years. Call (830) 356-2849 for an $89 seasonal tune-up and we will check the wear before it fails.
No. A frayed or corroded cable is a total replacement item. Splicing or clamping a cable creates a weak point that will fail under load, and no reputable shop will do it. The drum can sometimes be reused if the groove is clean and the hub is not cracked, but we only recommend that when the cable failed from external damage rather than age. We will show you the part and explain the call before we proceed.
Most Genie cable and drum replacements take forty-five minutes to an hour for a single side, ninety minutes if both sides need work. That includes door balance check, opener force adjustment, and safety sensor verification. We arrive with the parts, so there is no waiting on a delivery.
Yes. We carry 4-inch and 5-inch drums, 7 x 7 and 7 x 19 cables in standard lengths, and the common Genie bottom bracket configurations. For older Genie models or specialty drum hubs, we can source next-day if needed, though that is rare. We confirm the part match when you call so we do not waste your time.
