We stock Craftsman-compatible cable and drum assemblies on our trucks and install them across Alpharetta the same day in most cases. A complete cable and drum replacement typically runs $130 – $250 installed, depending on drum size, cable length, and whether one or both sides need work. Most Alpharetta homeowners discover the failure the hard way: the door jerks to one side mid-cycle, a cable snaps with a sharp crack, or the door slams down after the cable lets go. If you’re seeing any of that, the door is now unbalanced and unsafe to operate manually or with the opener.
Which Craftsman Models This Applies To
Craftsman garage doors sold through Sears and, later, Amazon and Lowe’s came with a range of hardware depending on the year and door weight. The cable and drum setup on a Craftsman 8×7 steel door with a torsion spring differs from the assembly on a 16×7 door with extension springs, and the drum diameter matters: 4-inch drums for standard lift, 5-inch or 6-inch for high-lift track configurations, and tapered drums on some older Craftsman models that never made it to the big-box shelves. The quick way to identify your hardware: look at the labels on the door’s end stile and the track. You’ll find the model number stamped on a white or silver tag. If the tag is gone, measure the drum diameter and count the cable’s strand construction; 7×19 aircraft-grade steel cable is the OEM standard on most Craftsman doors, and a thinner 7×7 cable was used on some lightweight models. We match against those measurements, not just the brand name. When OEM Craftsman-labeled parts are unavailable or backordered, we use quality aftermarket equivalents from the same suppliers that manufacture for the major brands. Brock Garage Doors Alpharetta is an independent service provider, not affiliated with Craftsman; we stock parts that meet or exceed OEM spec because that’s what actually keeps the door running in north Georgia humidity and heat.

Signs Your Craftsman Cable & Drum Replacement Is Failing
- Crooked door travel: One side of the door sits higher than the other as it moves. This almost always traces to a stretched or fraying cable on the low side, which changes the effective length and throws the lift geometry off.
- Visible slack in the cable when the door is open: A cable should stay taut throughout the full cycle. Slack means the drum isn’t spooling the cable correctly, often because the drum set screws have loosened or the cable has jumped the groove.
- Fraying or birdcaging near the bottom bracket or drum: Steel cables don’t fail cleanly overnight. In Alpharetta’s humid summers, moisture works into the cable strands and accelerates corrosion, and the first visible fatigue is almost always near the wear points. We see this constantly in older Craftsman doors in Windward and Crabapple.
- Grinding or scraping from the drum area: A worn drum with a scored or gouged cable groove will make noise every cycle. If left alone, the damaged groove eats the cable and the failure cascades.
- Door drops suddenly when released: If you pull the emergency release and the door feels heavier than it should or drops fast, the spring system isn’t carrying its share of the load. Often the cable has stretched or slipped, and the drum is no longer winding evenly.

AfterReplacement Cost & What’s Included
In Alpharetta, cable and drum replacement runs $130 – $250 installed for most Craftsman doors. The low end covers a single cable replacement with the existing drum in good condition. The upper end covers both cables and both drums, which is what we recommend when the door has more than 10 years on it; by the time one side fails, the other side has the same wear. The written price you approve before we start covers the parts, the labor, the rebalancing of the door, and a final cycle test. It also covers something most Alpharetta homeowners don’t expect to get: a 365-Day Done Right Promise in writing. If the cable or drum fails within a year, we come back and correct it at no charge. No verbal assurance, no fine print, no fee for the second trip.
| Service | Alpharetta Price Range |
|---|---|
| Single cable replacement | $130 – $180 |
| Both cables, standard drums | $180 – $250 |
| Both cables, both drums | $220 – $250 |
| Cable + drum with spring adjustment | $200 – $275 |
DIY or Call Us?
You can safely check two things yourself: inspect the cable for visible fraying and confirm the door’s model label is legible. That’s where owner involvement should end. The cables on a torsion-spring Craftsman door run under extreme tension, and a cable that releases while you’re working near it can throw a steel fitting or the cable itself with enough force to cause serious injury. Even a door with extension springs stores enough energy to break a hand. We’ve been on calls in Alpharetta where a well-intentioned DIY attempt turned a $150 cable job into a bent track, a shattered bottom bracket, and a door that needs a full realignment. If the cable has snapped, do not try to lift the door manually and do not run the opener. Call (229) 404-6747 and tell us what it’s doing wrong. We’ll figure out the rest from there.
FAQs
Cables on a well-maintained Craftsman door last seven to 12 years in north Georgia, but humidity, salt air if you’re close to the lakes, and infrequent lubrication can shorten that to five years. Drums are metal and rarely “break” unless an axle or bearing fails first; they wear through groove scoring and lose their ability to guide the cable cleanly. If your door is 10 years old and one cable is done, replace both cables and inspect the drums; the math almost always works in your favor at that age.
Cables cannot be safely spliced or repaired; once a strand is broken or the cable is stretched, it’s a replace-on-sight item. Drums can sometimes be salvaged if the grooves are clean and the set-screw holes are not stripped, but a scored or wobbling drum is not repairable. We’ll tell you honestly which side of that line your parts are on, and the written quote will reflect only what needs replacing. Call (229) 404-6747 if you want a straight answer before you commit.
A standard Craftsman cable and drum replacement takes 45 to 90 minutes on site, including rebalancing and testing the full cycle. If we find a worn spring or a failing bottom bracket during the job, we’ll quote that separately in writing before adding it; you approve every number before a single additional bolt turns.
Yes. We carry the most common Craftsman drum sizes, 7×19 cable stock, bottom brackets, and hardware on every truck that rolls to an Alpharetta job. Our technicians are trained on Craftsman systems along with LiftMaster, Chamberlain, Genie, and other major brands, so the right part goes on your door the first trip, not a generic substitute that sort of fits. For an exact quote on your Craftsman model, call (229) 404-6747; estimates are free, and the price you hear is the price you’ll see in writing.
