We replace LiftMaster cables and drums throughout San Diego, and most jobs run $155 – $295 installed. We carry LiftMaster-compatible cables and drums on the truck, so we can usually complete the swap the same day we come out. The typical call starts with a homeowner hearing a loud snap, finding the door hanging crooked, or noticing a frayed cable dangling loose near the top of the track.
The cable and drum work as a pair. The cable winds around the drum, and the drum translates the torsion spring’s force into lifting power. When either part fails, the door won’t move evenly, and that’s when you’ll see it cocked sideways or stuck partway up. Marcus Ellery has replaced hundreds of these across neighborhoods like Clairemont, Scripps Ranch, and North Park, and the failure pattern is usually the same: the cable frays first, then snaps, then the drum takes the shock and goes next.
Which LiftMaster Models This Applies To
This repair covers essentially every residential LiftMaster, Chamberlain, and Genie torsion-spring setup in San Diego: the older chain-driven series, the belt-driven openers that came with LiftMaster’s premium garage door lines, and current models still rolling out of the box. The part that matters isn’t the opener motor, it’s the torsion assembly above the door: the shaft, the two drums at either end, and the cables running down to the bottom brackets.
The compatibility gotcha we see often in San Diego is drum size. LiftMaster doors built for 7-foot-high openings typically use a 4-inch drum; 8-foot doors use a 5-inch drum, and some older D-style shafts need a stepped bore rather than a straight one. If the drum’s inner diameter doesn’t match the shaft, the cable stacks unevenly and fails again within months. We verify measurements on the door itself before quoting anything.
OEM LiftMaster parts are our default recommendation for doors under 10 years old, because the taper and cable-wrap profile match the spring’s cycle count. For doors past the 12-to-15-year mark, quality aftermarket drums and cables are often a smarter spend: same galvanized steel, same cycle rating, less money. We’ll tell you which makes sense for your specific door and your planned timeline in the house.

Signs Your LiftMaster Cable & Drum Replacement Is Failing
- The door hangs crooked or one side sits higher than the other. This is the most common first symptom. A stretched or frayed cable on one side means the drum on that side can’t keep pace with the other, so the door tilts as it moves.
- You can see frayed strands or kinks in the cable. Once strands start snapping, the cable loses about 30% of its rated strength within a few cycles. In San Diego’s coastal air, rust accelerates this even faster in beach communities like Ocean Beach and La Jolla.
- A loud snap comes from above the door while it’s in motion. That’s a cable letting go under load. The door may drop a few inches instantly. Do not stand under it or try to force it open.
- The door jerks, shudders, or makes a grinding noise as it lifts. When the drum’s groove wears down, the cable doesn’t wind cleanly anymore. It climbs over itself, and the door moves in little lurches instead of a smooth arc.
- One cable is slack while the other is taut. A broken or unwound cable on one side puts the full lifting load on the remaining cable and the spring on that side. The door is now working twice as hard as it should, which shortens the life of everything else.

AfterReplacement Cost & What’s Included
Cable repair in San Diego typically runs $155 – $295, with drum replacement loading toward the higher end of that range when both drums need to come out. Here’s the breakdown:
| Job | Typical Price Range (San Diego) |
|---|---|

| Both cables, parts & labor | $210 – $295 |
| Drum replacement (one side) | $180 – $260 |
| Both drums + both cables | $265 – $460 |
| Full LiftMaster cable & drum assembly | $240 – $395 |
Every quote includes the parts, the labor, re-tensioning the torsion spring, and balancing the door afterward so it opens and closes evenly. Before we touch anything, you get a written price. The number on that sheet is the number on the invoice. Our 365-Day Done Right Promise covers the repair for a full year: if a cable or drum we installed fails inside that window, we come back and make it right at no charge.
What drives the range? Drum condition is the big one. If the drum still has clean grooves and no wear, you’re only paying for the cable. If the drum has been chewed up by a snapped cable dragging against it, you need both. Door height matters too: 8-foot doors use longer cables and larger drums, which cost a bit more.
DIY or Call Us?
This one isn’t a judgment call, it’s a safety line. The cables on a LiftMaster door are under constant high tension from the torsion spring, and when they let go they move fast enough to cut through leather gloves. There is no safe way to re-tension a torsion system without the proper winding bars and a clear sense of where to stand. A cable that snaps under hand-loading sends the winding cone spinning hard enough to break bones.
What you can do safely: unplug the opener, keep the door closed, and take a photo of the make, model, and any label printed on the drum or the shaft. That’s useful information for when you call us. If the door is stuck partway open, don’t try to muscle it down, and don’t pull the release cord while it’s under load. Call (619) 374-2463 and talk us through what you’re seeing. We’ll get a technician out to your San Diego home, usually the same day.
FAQs
In coastal San Diego communities, expect 8 to 12 years from galvanized steel cables before fraying starts; drums can go 15 to 20 years if the cables haven’t snapped and scored the grooves. Inland and in the East County heat, sun exposure and temperature swings shorten that slightly. If you’re past the 10-year mark and seeing any fraying, replacement now beats an emergency later. Call (619) 374-2463 for an inspection.
No, and any tech who tells you otherwise is gambling with your door’s weight. Splicing or re-wrapping a frayed cable is never safe, never up to code, and never something a reputable San Diego shop will do. You replace it, and while ours is out we’ll check the drum and cable pad wear so you know exactly where the assembly stands. Call (619) 374-2463 for a written quote.
We complete a standard cable and drum swap in 60 to 90 minutes for most residential doors in San Diego. The longest stretch is de-tensioning the torsion spring, which we do before touching anything else. After the new parts go in, we re-tension, balance the door, and cycle it a half-dozen times to confirm everything runs clean.
Yes. Our vans carry standard 4-inch and 5-inch drums, both 7-foot and 8-foot cable lengths, and the matching bottom brackets for LiftMaster doors. We also stock compatible Chamberlain and Genie parts, so if your door turns out to be a different brand than the opener mounted on the ceiling, we can still fix it the same day. Call (619) 374-2463 and we’ll confirm what we’re bringing before we head out.
No. We quote the repair before any work begins, and that written price includes parts, labor, and re-balancing. The only thing that changes a quote is if you decide to add work while we’re there, and you’ll approve that new number before we do anything. That’s the Kingswell standard we run every job by in San Diego.
