The five things the inspection weighs
- The panel
- The door itself: the curtain, sections or tilt panel. Solid panel, easy call. Rust through the bottom rail, water-swollen timber, cracked sections: the door's structure is finished, and new springs can't fix structure.
- The spring
- Consumable by design. A failed spring on a sound door is the classic repair. A failed spring on a finished door is the classic trap: money spent twice.
- The running gear
- Rollers, hinges, cables, drums. Cheap to replace individually; telling when they're all worn at once, because the rest of the door is usually the same age.
- The tracks
- Bent or rusted tracks can be repaired or replaced alone, but heavily corroded tracks on an old door usually signal the whole system is at end of life.
- The opener
- Judged separately. A good opener happily drives a new door; a dying opener shouldn't decide the door's fate.
Three worked scenarios
These are typical scenarios, written to show the reasoning. They're not real jobs and no real customer appears in them.
Scenario A · the young door with a bang
An eight-year-old sectional in Macquarie Hills drops with a bang one school morning. Inspection: snapped torsion spring, everything else sound, panel unmarked, tracks true.
The call: repair. Springs are consumable; the door has decades left. Replace the spring, check its partner, rebalance, done. Anyone who quotes a whole new door for this is quoting their target, not your door.
Scenario B · the original that's finished
A tilt door original to a 1950s Cardiff South fibro. Rust through the bottom edge, panel sagging on its frame, tracks pitted, spring dead, and the door has been "going heavy" for years.
The call: replace. Every load-bearing part is at end of life at once. A new spring would move a finished door for a little while, and every dollar of that repair would be owed again within a couple of years. A sectional measured to the original opening is the honest spend.
Scenario C · the in-between
A 25-year-old roller door in Glendale: heavy, noisy, but the curtain is straight and rust-free. Inspection finds tired spring tension and bone-dry running gear, structure sound.
The call: yours, with the facts. A rebalance and service puts this door back in honest running order now; its age says start thinking about replacement on your own schedule rather than a breakdown's. You get both paths quoted and the trade-offs plainly, and nobody leans on you.
What "replace" actually involves
A free measure and quote: the opening measured properly (post-war openings are rarely square), the door types that genuinely fit it laid out, and a fixed quote for the door, hardware and fit. We fit doors from the mainstream Australian makers, described plainly, and we don't carry dealer badges or a reason to push one box over another. The full picture of the door types is in the glossary.
The one rule that holds every scenario together
Repair what has life left. Replace what's finished. Say which is which, and why.
That's the whole framework. It's also, not coincidentally, how the workshops up the road decided whether a part went back on a locomotive or into the scrap bin. The discipline travels.
Close the entry
If your door is somewhere in these scenarios, the next step is the same in all three: eyes on the door. Book a repair for a fault, or a free measure and quote if you suspect the answer is a new door. Undecided? The Overhaul Card will point you to the right visit.
