LiftMaster cable and drum replacement in San Antonio typically runs $130 – $250 installed, and we stock compatible cables and drums on our trucks for same-visit swaps on most residential LiftMaster models. You’ll know this part has failed when the door jerks going up, sits crooked in the opening, or you spot a frayed cable hanging loose near the side track. The cable and drum work as a matched pair – the cable winds onto that notched drum above the side of the door, and when either piece wears out, the other takes damage fast. In San Antonio’s heat, LiftMaster cables get brittle faster than most people expect, especially on west-facing garage doors that bake in the afternoon sun.
If you’re hearing that grinding, slapping sound from one side of the door, or the door won’t open at all because one cable snapped, that’s the situation we walk into most weeks across neighborhoods from Alamo Heights to Stone Oak. Jaylen Ross, our owner, puts it straight: “Tell me what’s broken. I’ll tell you what it costs. Then we fix it.”
Key Takeaways
- Cost: $130 – $250 installed for cable and drum replacement on a LiftMaster residential door in San Antonio.
- Speed: We carry LiftMaster-compatible cables and drums on the truck; most replacements are done in one visit.
- Safety: The cable assembly is under extreme tension. Do not attempt to remove or re-spool a cable yourself.
- Warranty: Every replacement is covered by our 365-Day Done Right Promise in writing.
- Compatibility: We match the exact cable length and drum style to your LiftMaster model before we touch a tool.

Which LiftMaster Models This Applies To
This guide covers the cable and drum assembly used on residential LiftMaster garage doors across San Antonio – from 7-foot doors on newer builds near The Pearl and Southtown to 8-foot doors on older homes in Terrell Hills and Castle Hills. The drum itself is the grooved wheel mounted on the torsion bar above the door opening. The cable winds into those grooves as the door closes and unwinds as it opens. LiftMaster uses model-specific drum geometries – a 4-inch drum with a specific taper on a standard 7-foot door, different again on an 8-foot door or a low-headroom track setup.
You can identify your exact part by checking the white label on the door panel itself, not the opener motor. That label lists the door’s manufacturer, model number, and cable length. On LiftMaster residential doors, the label is usually near the bottom of the top section, behind where the opener arm connects. If the label is gone – common on doors that predate the Obama administration – we measure the cable length and drum diameter on site.
One compatibility gotcha we see repeatedly: homeowners order a “LiftMaster cable” online assuming one size fits all, then discover the replacement is two inches too short or the drum doesn’t seat correctly on the torsion bar. We match the parts to your exact door, not just the brand name. We use OEM LiftMaster cables and drums when available and quality aftermarket equivalents from the same manufacturers we trust for Chamberlain and Genie doors when OEM lead times stretch too long. Both hold up, but the aftermarket route only works when the specs line up on cable diameter, length, and end fitting style.
Signs Your LiftMaster Cable & Drum Replacement Is Failing
- The door jerks or shudders on the way up. A cable that’s starting to fray doesn’t wind smoothly into the drum grooves. You’ll feel the door hesitate and lurch as the cable catches, releases, and catches again.
- One side of the door sits lower than the other when closed. When a cable stretches or the drum slips, the lift becomes uneven. The door may look fine for weeks while the problem quietly worsens.
- You can see loose wrap, gaps, or overlapped coils on the drum. A properly seated cable wraps flush against itself in a single neat layer. Overlaps mean the drum groove is worn or the cable has stretched – and both get worse every cycle.
- The cable looks shiny, fuzzy, or has broken wire strands near the bottom bracket. That shine is metal fatigue. In San Antonio’s dry heat, the outer strands oxidize and harden, then snap one at a time until you’re left with a pencil-thin thread holding the door up.
- The door is stuck partway with one cable completely off the drum. This is the failure mode we see after a hard close or an opener forcing the door down against an obstruction. The cable jumps the drum, snarls around the shaft, and the door wedges in place.

AfterReplacement Cost & What’s Included
In San Antonio, LiftMaster cable and drum replacement costs between $130 and $250 installed. The final number depends on three things: whether you’re replacing one cable and drum or both (we almost always recommend both – replacing one side only leaves you with a mismatched pair and a future call), whether the drum is standard or low-headroom, and whether the cable damage pulled the door out of alignment.
Here’s the breakdown:
- Single cable replacement: $130 – $180
- Single cable plus drum: $160 – $220
- Both cables and both drums: $190 – $250
- Track realignment (if the cable failure pulled things out of line): $120 – $240, quoted separately if needed
The written price you get before we start includes the parts, the labor, the balancing of the door, and a full cycle test. It’s the same number on the invoice when we finish. Every cable and drum replacement we do is covered by the 365-Day Done Right Promise, which means if the fix fails within a year, we come back and make it right at no charge. That’s stated in writing on the quote, not hidden in fine print.
DIY or Call Us?
Here’s the honest answer, because you deserve it: the cable and drum system on a LiftMaster door is not a safe weekend project. The cables are connected to a torsion spring that’s wound under enough tension to break bone or worse if it releases suddenly. In the garage door trade, cable and spring injuries are the ones we warn our own families about. You should call a trained professional for any cable or drum replacement, period.
What you can safely do is inspect. Look at the cables where they meet the bottom bracket. Look at the drum for clean, even winding. Photograph what you see. Then call us. Jaylen Ross has been running crews across San Antonio for well over a decade, and he’s lost count of the number of times a homeowner tried the “one YouTube video and a screwdriver” approach and ended up paying double to fix the mess. Call (361) 314-2738, tell us what you’re seeing, and we’ll give you a written price before we ever touch the door.
FAQs
LiftMaster cables typically last 7 – 12 years in San Antonio, but doors that face west or southwest can see cable failure in 5 – 7 years because the afternoon heat accelerates the metal fatigue inside the wire strands. Drums usually outlast two cable replacements, but we inspect both on every call and replace the drum if the grooves show any flattening or uneven wear. Call (361) 314-2738 and we can tell you over the phone whether your door’s age and orientation put it in the replace-now or watch-and-wait category.
No. A frayed cable cannot be safely repaired – once the individual wire strands start snapping, the cable is weakening unpredictably and can fail completely under a full load. Splicing, taping, or crimping a residential garage door cable is dangerous and will not hold. Replacement is the only correct fix, and at $130 – $250 in San Antonio, it’s the cheaper option compared to the damage a snapped cable can do to the door, the track, and anything parked underneath it.
On a standard LiftMaster residential door in good alignment, we complete a cable and drum replacement in 60 – 90 minutes once we’re on site. If the cable failure also pulled the tracks out of alignment or damaged the bottom bracket, the visit will run longer, typically about two hours. We’ll tell you the time estimate up front, and you’ll see your tech tracking toward your house with The Relay Visibility Guarantee before we arrive.
Yes. Our trucks carry LiftMaster-compatible cables in all common residential lengths, plus drums for standard 7-foot and 8-foot doors, low-headroom setups, and the high-lift configurations we see in some San Antonio custom garages. For unusual or discontinued LiftMaster models, we source OEM parts and return within one to two business days. We also keep parts for Chamberlain and Genie doors on the same trucks, so if you’ve got a second door from another brand, we can handle that in the same visit. Call (361) 314-2738 for a free estimate.
