Broken torsion and extension springs swapped for correctly matched sets.

Frayed, slack or unwound lift cables renewed and rewound evenly on both drums.
What's involved
Garage Door Cable Repair
Lift cables are the quiet part of the system. They run from the bottom brackets up to grooved drums on the torsion shaft, and they translate the spring's stored energy into lifting the door evenly on both sides. When a cable frays, slips a wrap or snaps, the door immediately stops travelling square, and a door out of square is on its way out of the track. Cable work is fast when caught early and expensive when it is not.

Symptoms
Signs You Need This Service
- One side of the door lifts before the other, or the door hangs crooked
- A cable is visibly slack, kinked, or hanging free beside the door
- Frayed strands or a broom-straw appearance near the bottom bracket
- The door jams in the tracks part-way through its travel
- A grinding or slapping sound from one side as the door moves
Repair or replace?
Galvanised lift cables commonly last ten to fifteen years in a dry garage and notably less in a damp, salted one. They rarely fail without warning, though: fraying, kinking and rust staining at the bottom fitting appear first, which is why an annual look at the lowest few centimetres of both cables is worth more than any other inspection you can do yourself. Replacing cables in pairs, keeping the threshold draining away from the door and keeping the counterbalance correct are what get you to the top of that range.

Root causes
What Actually Goes Wrong
Corrosion at the bottom of the cable
The lowest few centimetres of cable sit where water, snowmelt and road salt collect against the threshold. That is where cables rust from the inside of the strand outward, so a cable can look acceptable at eye level and be nearly gone at the fitting. This is the single most common cable failure in Hamilton's older east-end and lakeside garages.
A spring failure that shock-loaded the cable
When a spring breaks, the load it was carrying arrives somewhere else in an instant. Cables are frequently kinked, stretched or thrown off their drums by that event, which is why cables are always inspected as part of a spring repair rather than treated as a separate item.
Drum, bracket or track misalignment
A drum that has slipped on the shaft, a bent bottom bracket or a vertical track that has shifted will make a cable run at an angle. Running at an angle abrades the strand against the drum flange, and abrasion at one spot is how a cable that is otherwise sound fails early.
A door that hit an obstruction
If the door closes onto a bin, a snowbank or a vehicle bumper, one cable goes slack while the drum keeps turning. The cable then rewinds badly or jumps its groove. On short lower-city driveways and narrow laneway aprons, obstructions near the threshold are a routine hazard rather than a rare one.
Local conditions
Why This Matters in Hamilton
Road salt is the local villain here. Hamilton receives around 156.5 centimetres of snowfall in a season at the airport station, and the salt that comes with clearing it arrives in the garage on tyres and boots and ends up in the meltwater at the threshold. Lower-city and Stoney Creek lakeside garages, many of them unheated and built before 1961, give that mixture the longest contact time with the cable ends. Rinsing the bottom of the door and the threshold after the salt season is a small habit with a measurable payoff.
Safety
What to Handle Yourself
Cables are under spring tension whenever the door is not fully supported, and the bottom bracket they attach to is one of the most dangerous fittings on the door. Never loosen a bottom bracket, never try to re-seat a cable on a drum by hand, and do not run the opener to see whether a slack cable will sort itself out. If a cable has snapped, keep the door down and out of use. A door hanging on one cable can twist out of the track without warning.
The visit
How We Work Through It
-
Secure the door before touching anything
A door with a failed cable is not properly supported. It is secured in the track and the opener is isolated so it cannot pull against it. Only then is the bottom bracket area approached, since that bracket is under cable tension and is a known injury point.
-
Find out why the cable failed
Replacing a cable without establishing the cause guarantees a repeat. The drums, shaft, bearings, bottom brackets, track alignment and spring condition are all inspected, and the failure pattern on the old cable usually says which of them is responsible.
-
Fit matched cables and set the winds
Cables are replaced in pairs so both sides have the same condition and length, seated properly in the drum grooves and wound so that tension is equal at rest. Even tension is what keeps the bottom section level throughout the travel.
-
Cycle, square and retest
The door is cycled by hand and then under power, watching the bottom section for level travel and listening for contact at the drums. Limits and force are reset if needed, and the photo eyes and contact reverse are tested before the visit finishes.
Questions
Garage Door Cable Repair FAQs
Can I just put the cable back on the drum myself?
It is not a do-it-yourself job, because the cable is only slack while the door is resting somewhere it should not be relied on to stay. Re-seating a cable means managing spring tension, and the bottom bracket end of it is where injuries happen. Cables that have jumped a drum have usually been kinked in the process too, so they need replacing rather than refitting.
Should both cables be replaced when one fails?
Yes. They are the same age, have taken the same number of cycles and have sat in the same damp corner of the garage. Replacing one leaves you with a mismatched pair and a second call in the near future, and unequal cable condition is exactly what puts a door out of square.
Why did my cable fail so soon after a spring replacement?
Most likely it was already damaged by the spring failure itself, or the drums and bearings were left as they were. A spring breaking shock-loads everything downstream of it. That is why a proper spring job includes a cable and drum inspection, and why an honest quote sometimes covers more than the part that visibly broke.
Is a rusty cable urgent even if it still works?
Treat it as urgent. Cable corrosion progresses inside the strand, so the visible surface understates it, and the failure mode is sudden. A door dropping because a cable let go is one of the more dangerous things a garage door does. Replacing a rusted cable is inexpensive compared with repairing what a dropped door damages.
