Garage Door Repair Cape Town
A garage door that will not open is not a small inconvenience. If the house is your only parking, the car is trapped. If it is stuck open, the house is not secure. Most failures come down to one of a short list of parts: a torsion spring that has snapped, a cable that has jumped its drum, a roller that has left the track, or a motor that has stopped responding. This page explains the common causes, what is safe for you to check, and what the repair actually involves.
The failure you are most likely looking at
- A snapped torsion spring. The door feels impossibly heavy, the opener strains or clicks and nothing moves. This is the single most common cause of a door that will not lift, and it is the one you must not work around.
- A cable off the drum. One side of the door drops lower than the other, or the door goes up crooked and jams. The cable has usually come off because the door is out of balance.
- A roller out of the track. The door shudders, scrapes or stops halfway with a bang. Often the track itself is bent where something struck it.
- A dead remote or opener. The door will not respond to the remote but the wall button works, which points at the remote, the receiver or the battery rather than the door.
- A safety sensor blocked or knocked out of line. The door starts down and reverses immediately, or refuses to close at all. Look at the two small eyes at the bottom of the track.
- Worn hinges, rollers and bearings. The door opens and closes but noisily, and it gets worse every month. Noisy is the early warning, not the fault.
What you can safely check before you call anyone
- Whether the remote works and the wall button works. If the wall button runs the door, the motor is fine and the fault is in the remote, its battery or the receiver.
- Whether both safety eyes are lit and pointed at each other. A simple misalignment stops a door closing, and it is a two-minute fix to test.
- Whether anything is under the door or in the track. A stone, a piece of packaging or a broom handle in the track stops a door dead.
- Whether the door is visually crooked. Stand back and look at the gap at the bottom of the door on both sides. If one side sits lower, stop using the opener.
What is never a good idea
- Do not try to wind, unwind or replace a torsion spring yourself. A tensioned torsion spring stores enough energy to break a wrist or kill. This is the one part of a garage door that a homeowner should never touch.
- Do not keep pressing the opener on a door with a broken spring. The motor will burn out its gear or its capacitor, which turns one repair into two.
- Do not force a crooked door down by hand to secure the house. If it jams halfway it is harder to release than it was to close.
- Do not cut a cable or remove a hinge to get the car out. The door is under load and can drop.
- Do not accept a quote for a full replacement door before someone has actually looked at the mechanism. Most stuck doors are a repair, not a new door.
What the repair visit involves
- The contractor looks at the whole mechanism, not just the broken part: springs, cables, drums, rollers, hinges, track, brackets and the opener.
- The door is balanced first. A door that is not balanced will destroy a new spring or a new motor in months, so balance is not optional.
- Only the failed parts are replaced. Ask for the old part back if you want to see what failed.
- The opener's force setting and travel limits are reset after a spring or cable repair, because the load on the motor has changed.
- The safety reverse is tested before the job is signed off. If the door does not reverse on contact, the job is not finished.
- You get a written scope before work starts, and a clear answer on what is covered afterwards.
What drives the cost of a repair
- Which part failed. A roller, a hinge and a remote are small jobs. A matched pair of torsion springs and a service is a bigger one.
- How many parts are worn together. Springs, cables and rollers usually wear out as a set, and replacing one and leaving the rest means a second call-out.
- Whether the door is balanced and adjustable, or bent and out of square from years of running crooked.
- Access and height. A double sectional door in a low-roof garage is slower to work on than a single roll-up.
- The type and age of the door. Older timber and tip-up doors take longer to set up than a modern sectional.
- Time and day. After-hours and weekend call-outs are priced differently from weekday work.
- The plan publishes no price list for this network and we do not publish a price that a contractor has not confirmed. Ask the contractor for the call-out fee and the rate before work starts.
How to choose the contractor who repairs your door
- Ask what they will check before they quote. A repair quote that does not mention balance is a quote from someone who plans to fit a part and leave.
- Ask whether the springs will be a matched pair and ask for the spring spec on the invoice.
- Ask if the track, rollers and hinges will be inspected at the same visit, because a second call-out costs more than the inspection.
- Ask what happens if the repair does not fix the fault. A contractor confident in the diagnosis will say.
- Ask for the old parts back if you want to see what failed - it is a fair request and it keeps everyone honest.
Repair or replace - how the decision should be made
- If the panel, the drum and the bracket assembly are sound, repair is almost always the better spend.
- If the door is warped, the frame has moved, or the panel is cracked through a stress line, a repair buys months rather than years.
- If the parts are unavailable because the door is a model that is no longer made, the decision is forced.
- If the door has failed twice in a year for different reasons, the pattern is the message.
- A new door is also an opportunity to fix the things a repair cannot: draughts, water under the seal and a noisy opener.

Frequently asked questions
Can I still open my door if the spring has broken?
Only if you can lift it safely with help, and only to get the car out. A door with a broken spring weighs far more than it should, so treat it as unsafe and get it repaired before using the opener again.
Is a stuck garage door an emergency?
It is urgent rather than dangerous in most cases, but a door stuck open leaves the house unsecured. Say so when you send the details and it will be routed as a priority job.
Why does my door go up crooked?
Almost always a cable off its drum or a spring that has lost tension on one side. Stop running it, because the track bends and the door panel can crack.
Can the door be repaired on the spot?
Most repair call-outs are completed in one visit, because the common parts - springs, cables, rollers, hinges - are carried on the van. A door that needs a specific panel or a matched spring can take longer.
Do you replace the whole door when a part fails?
No. A repair is offered first. A replacement is only the right answer when the door panel or the drum and bracket assembly is beyond repair.
How do I know a repair is not just a patch?
A proper repair leaves the door balanced, quiet and reversing correctly. If the door is still heavy or still crooked after the visit, the job is not finished and you should say so before paying.
Will you tell me if a replacement is the better spend?
Yes. A repair is offered first, and a replacement is only recommended when the panel, the drum or the bracket assembly makes repair uneconomic. Ask for that reasoning in writing if you are unsure.
How do I know when a door is genuinely beyond repair?
When the panel is cracked, the frame has moved or the parts no longer exist. Anything else is usually repairable, and a contractor should say which of those three applies.
Will a repaired old door still be noisy?
It can be made much quieter by replacing worn rollers and hinges in the same visit. Noise is usually the parts, not the door.
