Garage door spring and cable repairs in Toowoomba

Replacing broken or worn springs, frayed lift cables and drums, then rebalancing the door so it lifts safely.

Why springs and cables matter

Springs do most of the work of lifting a garage door. They store energy as the door closes and release it as the door opens, so a person or a small motor can move a heavy door. On sectional and tilt doors, lift cables connect the bottom of the door to the spring system. When a spring breaks or a cable frays, the door can become far too heavy to lift, sit crooked or fall.

B&D says a broken spring can cause "an imbalanced door or complete operational failure", and that "DIY spring repair is highly discouraged due to the complexity and potential danger involved" (B&D). It also warns that a snapped cable can make the door "fall unpredictably" (same source).

Types of springs

• Torsion springs sit on a bar above the opening on many sectional doors and wind up as the door closes. They are under high tension. Only a trained technician should adjust or replace them.
• Extension springs run alongside the horizontal tracks on some sectional and tilt doors, and stretch as the door closes.
• Roller door springs sit inside the drum the curtain rolls onto. See roller door repairs.

Warning signs

• A loud bang from the garage, then a door that will not lift.
• A visible gap in a torsion spring coil.
• The door feels much heavier than usual, or only lifts a short way.
• The door sits crooked, or a cable hangs loose.
• The opener strains, stops part way or reverses.
• Frayed, rusty or kinked cables near the bottom corners of the door.

If a spring or cable breaks

1. Stop using the door and the opener. Running the motor against a broken spring can strain it.
2. Keep children and pets away from the door.
3. Do not try to wind, release or remove a spring, and do not pull on cables.
4. Be careful with the manual release. Steel-Line warns that when the door is open, "the door may fall rapidly due to weak or broken springs" (Steel-Line).
5. If your car is stuck inside, choose the urgent option on the quote form.

What a spring repair involves

The technician should identify the spring type and size, replace it with springs matched to the weight of the door, and then test the balance by hand with the motor released. On doors with a pair of springs, they may suggest replacing both at once so the door stays balanced; ask them to explain why. A good repair also includes a check of the cables, drums, bearings and opener settings, because a broken spring often puts strain on the rest of the system.

Published prices

Published estimates put a single spring replacement at around $180 to $350 and a pair at $280 to $550, with lift cable replacement at $110 to $400 per job (What's The Damage?, Brisbane, October 2026). An older Airtasker guide put typical spring repairs at $110 to $200 and cable repairs from $150 (Airtasker, updated 6/11/2023). These are national or Brisbane estimates, not Toowoomba quotes. See the full garage door price guide.

Questions to ask

• Which springs are you replacing, and why?
• Are the new springs matched to the weight and size of my door?
• Will you check the cables, drums and opener at the same time?
• What warranty applies to the parts and to the labour?
• Is there anything else on the door likely to need work soon?
