Repair it, or replace it? How the call actually gets made

The one distinction that decides most of it

Nearly everything on a garage door falls into one of two buckets, and the bucket matters more than the age of the door.

Bucket	What's in it	Which way it usually tips
Mechanism	Springs, cables, rollers, hinges, tracks, the opener	Repair. These are wear parts. They're designed to be replaced, and replacing them is routine work.
Structure	The panels or curtain, the frame, the bottom rail, the door's basic squareness	Replace, once it's genuinely gone. You can't re-tension rust, and straightening a badly racked door is throwing good money after bad.

A snapped spring on a forty-year-old tilt door sounds catastrophic and usually isn't: the spring is mechanism, and if the door itself is straight and sound, new springs give it years more. A door with a rusted-through bottom rail can feel fine to operate and already be finished: the structure is going, and every repair from here is a patch on a patch.

The questions we actually ask at the door

• Is the structure sound? Straight panels, a square frame, a bottom rail that's steel rather than rust. If yes, almost any mechanism fault is worth fixing.
• Is this the first fault, or the latest one? One failure in years of service is wear. The third callout-worthy fault in eighteen months is a door telling you something, and we'll pass the message on.
• What would the repair buy? A repair should buy years, not weeks. If the fix in front of us is sound but the next failure is already visible, we'll say so before you spend.
• Does the repair cost make sense against a new door? No dollar figures on this site, deliberately, but the principle is simple: when a repair starts costing a meaningful fraction of a replacement, on a door that's structurally near the end anyway, the money belongs in the new door. We'll tell you when you're in that territory, with the actual numbers in front of you on the day.
• Is there a safety question? Frayed cables, cracked spring anchors, a door that free-falls when the opener is disengaged. Safety faults outrank economics. They get fixed or the door gets retired; "she'll be right" is not one of the options we offer.

The opener wrinkle

Openers deserve their own paragraph, because they hide problems. An opener will keep dragging an out-of-balance door long after a human arm would have noticed something was wrong, right up until the motor quits. So when an opener dies, the honest first question isn't "which new motor", it's "why did this one die". Often the answer is a door that needs re-balancing, and fitting a new motor without fixing that just schedules the next failure.

Openers are also the one part of the door with a real safety standard story: modern units have auto-reverse behaviour for a reason, and recalls do happen. The ACCC's product safety recall list for garage door openers is public and worth a look if yours is old, and the relevant Australian standard for these units (AS/NZS 60335.2.95) exists precisely because a powered door that can't sense an obstruction is dangerous. We describe what standards cover; we don't certify anything from a web page, and neither should anyone else.

Where the honest call earns its name

Here's the part that costs us money and wins us neighbours: sometimes the right answer is "don't spend anything yet". A door that's noisy but balanced, old but straight, ugly but sound, doesn't need us this year. We'll tell you that, note what to watch for, and leave. The enquiries that come back to us two years later, when the door genuinely is done, are why.

If you want the quick version of all this logic, the which-side-of-the-line tool on the front page walks you through it in a couple of minutes. It gives you a lean, not a verdict, for the same reason this guide does: the honest call needs eyes on the actual door.
