Garage Door Garage Door Cable Repair St. John, MO
Homeowners across Schuermann Heights and the surrounding St. John area call us for garage door cable repair because we know St. John. The common drivers locally are degraded weatherstripping from UV and moisture, moisture-tripped openers and sensors after storms, rusted track hardware and seized rollers, and mildew and rust on shaded, north-facing doors — and we fix the cause, not just the symptom.
In Missouri's humid subtropical region, hot, humid summers and short, mild winters, with frequent storms and moisture that lingers in the air most of the year. For St. John garages that translates into damp garages that pit galvanized parts over time, mildew and moisture on shaded, north-facing doors, and salt-tinged coastal air that accelerates rust near the shore, so our tune-ups focus on the components that wear first under these conditions.
From Schuermann Heights and the surrounding St. John area, the issues St. John customers describe are typically degraded weatherstripping from UV and moisture, moisture-tripped openers and sensors after storms, rusted track hardware and seized rollers, and mildew and rust on shaded, north-facing doors. We quote flat-rate, fix it in one trip, and back the work for 10 years.
Lift cables transfer the spring's stored energy to the door panels — they're under high tension every cycle and degrade slowly through fraying, corrosion, and mis-spooling on the drum. A cable repair visit replaces both cables (always replace as a pair so the door stays balanced), re-spools the drums to the correct number of wraps, recalibrates spring tension to match, and inspects related components like the bottom bracket where one end of each cable terminates.
Cables are galvanized aircraft-grade steel — typically 1/8-inch diameter for residential doors and 3/16-inch for heavier or commercial doors. We carry both diameters along with the bottom-bracket fittings, drum caps, and shaft set-screws that occasionally need replacement alongside the cables.
Cable failure usually leaves the door off-track or hanging crooked. Continuing to operate the opener after one cable has snapped causes the other side to take the full load and is the fastest way to bend tracks or damage panels. Stop the opener and call for repair when you see a frayed or snapped cable — fast service is standard.
Signs you need garage door cable repair
Frayed cable visible at the drum
Strands of steel poking out of the cable indicate active wear. Cables don't self-heal — frays accelerate to snap.
Door hangs crooked when closed
If one corner is higher than the other when the door is fully down, one cable has stretched, slipped on the drum, or partially failed.
Snapped cable, door stuck
A fully snapped cable leaves the door off-track or jammed. Don't try to force it — call for repair.
Rust streaks on cables
Coastal homes see cable corrosion progress until the strands weaken. Visible rust means the cable is no longer at full strength.
Loud bang followed by crooked door
Cable snap sounds similar to spring snap but is usually quieter. If the door is crooked after the noise, suspect cable failure.
Common causes & what we fix
Mis-spooled drum
When a cable jumps off its drum groove, it crosses over itself and wears at the crossover point. Re-spooling fixes the spool but the wear point becomes the weak link.
Drum cap or set-screw failure
If the drum slips on the shaft, one cable unwinds while the other tries to hold. This sudden imbalance can snap the loaded cable.
Bottom bracket failure
The bracket where the cable attaches at the door bottom occasionally cracks or pulls free, letting the cable whip free under tension.
Coastal corrosion
Salt-air pitting on uncoated cables can drop tensile strength 30–40% over 10+ years. Galvanized aircraft cables resist this far better.
Spring imbalance
An over- or under-tensioned spring puts uneven load on the cables and accelerates wear on the loaded side.
