Springs wear out by the cycle
Every time the door opens and closes, the springs use up one cycle. B&D rates its Panelift springs at 10,000 cycles, Panelift Icon at 20,000 and Roll-A-Door at 30,000, so a busy family garage gets through them faster than a door used once a day.
B&D's manual also says springs naturally lose tension over time. A door that has slowly become harder to lift, or a motor that has started to labour, can be a spring near the end of its life rather than a failing motor.
Before cyclone season
Sunshine Coast Council says cyclones can occur from December to April. The coast sits in Wind Region B on the 2011 map, where homes are built for weakened tropical cyclones, and the 2023 emergency management report on south east Queensland says they are not designed for the pressure that builds inside when a door gives way.
So spring is a sensible time for a service. A door that is balanced, running straight in its tracks and locking properly is the one you want shut when a storm comes through.
Servicing a Sunshine Coast door
- Steel-Line's sectional door manual asks for preventive maintenance at least every six months, more often if conditions call for it.
- B&D recommends a regular service every two years for its sectional doors.
- Lightly oil the hinge points, roller stems and locks, as Steel-Line's manual describes, but keep oil and grease off the tracks.
- Steel-Line says owners should never paint the tracks, rollers, hinges, lift cables, springs or locks.
A loose cable or a door off its track
The lift cables carry the whole weight of a sectional door, Steel-Line says, so a frayed or slack one is a job for experienced door people only. If the door has come off its guide rails, B&D's advice is not to lift it back on yourself: a spring or cable may already have broken.
Repairs around the Sunshine Coast
Coastal streets
Before paying for rust repairs on a newer door near the beach, check the maker's terms. Steel-Line's warranty does not reach installations within 800 metres of the sea.
Leafy streets
If leaves and dust keep finding their way under the door, ask about seals. B&D says its Panelift Icon has 360° perimeter seals to help keep them out, which its standard Panelift does not.
Licences
A repair valued over $3,300 needs a QBCC licence in Queensland. Below that, QBCC says it cannot step in if things go wrong, so get even a small quote in writing.
What we would do
If the door has not been serviced in a couple of years, book it for spring rather than waiting for a fault. Ask the door specialist to check the spring balance and the cables while they are there, since those are the parts you should never touch yourself.
