Raynor cable and drum replacement in San Antonio typically runs $130 to $250 installed, and we stock Raynor-compatible cables and drums on our trucks for same-day or next-day service across the city. The cable is the braided steel line that lifts the door, and the drum is the grooved spool at the top that winds it. When either fails, you will usually see the problem before you hear it: a frayed cable dangling loose, a door cocked sideways in the tracks, or a grinding noise from above the opening. Cable and drum failures rarely announce themselves with a clean break. More often, the evidence is a door that suddenly runs rough, jerks mid-travel, or refuses to stay level. If you are seeing any of that on a Raynor door, the rest of this page tells you exactly what we replace, what it costs, and how the job goes. It is a repair we handle several times a week in neighborhoods all over San Antonio, from Stone Oak to Alamo Heights to the older subdivisions west of Blanco Road.
Key takeaways:
- Installed cable and drum replacement for Raynor doors runs $130 – $250 in San Antonio, written and agreed before we start.
- We stock Raynor-compatible cables and drums on the truck, so most calls are one visit.
- Cables and drums should always be replaced as a pair, not one side only.
- This is a high-tension job. We do not recommend DIY cable work on any torsion-spring door, Raynor included.
- Every replacement is covered by our 365-Day Done Right Promise.
Which Raynor Models This Applies To
Our technicians are trained on Raynor residential doors across the current and recent model range. The cable and drum setup we most often service in San Antonio includes the Raynor Aspen, RockCreeke, and Tradition series for single and double doors, plus the heavier build on Estate and ShowCase models in some of the larger custom homes around the Dominion and north of Loop 1604. Most Raynor residential doors use a standard torsion shaft with cast aluminum or stamped steel lift drums, and a 7-foot or 8-foot cable size. The main compatibility gotcha we see: Raynor drums are machined for a specific cable length and shaft diameter, and using a generic drum from another brand can cause the cable to stack unevenly on the spool. That is a real issue, because uneven stacking is exactly what frays a cable early. When you call, we will ask for the model name or the number on the sticker inside the door panel, and we will confirm drum size and cable length on site before any part goes on the door. We use OEM Raynor parts where they are available quickly and a quality aftermarket equivalent where it is the same gauge, same length, and same winding geometry. Either way, the price is quoted before the work, and both options are covered by the same 365-day warranty.

Signs Your Raynor Cable & Drum Is Failing
- A cable looks loose or has visible fraying. Braided steel starts to separate strand by strand before it snaps. If you see a fuzzy or unraveled section anywhere along the cable, it is already on borrowed time. On Raynor doors, this often starts where the cable enters the drum due to slight misalignment over years of San Antonio heat cycling.
- The door lifts unevenly or jams partway up. When one cable stretches or slips on its drum, the door rides higher on one side. The roller in the track may bind, and the opener will strain or reverse. This is the symptom most San Antonio homeowners notice first.
- The top of the door bangs or grinds when opening. A worn drum with chipped grooves lets the cable jump and reseat under load. That produces a metallic clicking or grinding from directly above the opening, and it will only get worse with continued use.
- The cable has slipped off the drum entirely. You will see a bare drum and a cable lying loose along the track or coiled at the bottom. The door may still open partially from the other side, but this is a full failure, not a cosmetic one. Do not run the door on the opener in this condition.
- The bottom of the door shows a gap on one side when closed. A cable that has stretched unevenly or a drum that has slipped on the shaft changes the resting position of the door. Left too long, it pulls the door out of square and accelerates track and roller wear.

AfterReplacement Cost & What’s Included
Cable and drum replacement on a Raynor door in San Antonio runs $130 to $250 installed, depending on door height (7-foot doors are at the low end, 8-foot doors at the high end), whether we are doing one side or both (we always recommend and price both as a pair), and whether the drums are standard Raynor stamped aluminum or the heavier cast type found on some Estate and ShowCase series doors. The price you get is a written price, presented before any work begins, and it includes the cost of the parts, the labor, a full tension check and rebalance of both cables, a track alignment check, and a quick hardware tighten across the door. We do not tack on a “trip fee” or a “parts surcharge” after the fact. If we quote $210, you pay $210. We also photo-document the before and after, and we verify the door runs quietly half a dozen times before we consider the job done. Every cable and drum replacement is covered by our 365-Day Done Right Promise: if it is not right, we make it right, no charge and no negotiation.
DIY or Call Us?
The honest answer on Raynor cable and drum work: this is not a DIY job. The cables on a Raynor torsion door run under full tension from the springs, and a cable that slips or snaps during a partial disassembly can release that tension violently. We have been called to more than one San Antonio home where a well-meaning owner removed a cable without a winding bar and ended up with a bent torsion tube and a damaged door panel, not just a broken cable. The consequences of getting it wrong are serious enough that we would rather you call us than risk it. What you can safely do is turn the opener off, leave the door closed, and take a photo of the cable and drum from a few feet away. Send it or describe it to the live person who answers our phone at (806) 602-8374, and we will tell you whether it sounds like a standard cable-and-drum swap or something more involved before we even schedule the truck. We carry the parts for Raynor doors on the truck, so when we arrive, we can usually have the job done and your door running smoothly again the same visit. Call us before you grab a ladder. It will save you more than money.
FAQs
We typically see Raynor cables last 8 to 14 years in San Antonio, with drums lasting somewhat longer unless the cable has been running misaligned for an extended period. The two constants that wear them out here are heat and humidity. Long stretches of 100-degree days harden the cable’s lubrication and make the braids slightly less flexible, and the humidity from a coastal front can add surface corrosion on doors that are not in a conditioned garage. If your Raynor door is past the 10-year mark and you are seeing any fraying on a cable, replacing the pair now is cheaper than replacing the secondary damage later.
No, and we will not try. Once a braided cable has broken strands, its strength is permanently reduced, and a repaired cable does not have a predictable breaking point. A drum with worn or chipped grooves causes uneven winding and will damage a new cable within months. The part must be replaced, and on a torsion system, both sides should be done together. The good news is that cable and drum replacement is one of the more affordable repairs on a Raynor door, especially compared to a door panel or an opener.
Most Raynor cable and drum replacements take about an hour to an hour and a half once we are on site. That includes removing the old parts, installing the new cables and drums, rewinding the springs to the correct tension, setting both cables evenly, rebalancing the door, and running it through several full open-close cycles to make sure it tracks straight and runs quiet. If the door has additional issues beyond the cable and drum, we will point them out and give you a separate written price for any additional work before we do it.
Yes. We keep a range of Raynor-compatible cables in both 7-foot and 8-foot lengths, and we stock standard and high-lift Raynor drum profiles on our service vehicles so we can complete most cable and drum calls in one visit. We also carry parts for LiftMaster, Chamberlain, and Genie openers, along with service parts for the other major door brands our technicians are trained on. For uncommon sizes, we can usually have the exact part in hand the next business day, and we will tell you plainly if that is the case before we schedule.
If your Raynor door is showing any of the signs we covered here, call us at (806) 602-8374. A live person answers around the clock, and we will help you figure out whether the problem is the cable, the drum, or something else entirely. Estimates are free and the price we quote is the price you pay, written before any work starts.
