It Needs More Attention Than You Think
Most homeowners do not think about their garage door until it stops working. That is understandable. It opens, it closes, it does its job. But a garage door is the largest moving part on your home, and it operates under significant mechanical load every single day.
A bit of basic maintenance keeps it running reliably for 15 years or more. Without it, you are looking at breakdowns, repair costs, and in some cases a full replacement well before the door has reached the end of its useful life.
Here is what you need to know, whether you are in a new build or have had the same door for a decade.
Most garage door failures are avoidable
Torsion springs do most of the heavy lifting every time your garage door moves. They are rated for a set number of cycles, typically between 10,000 and 20,000 depending on the grade. If your household uses the garage door four times a day, you will hit 10,000 cycles in under seven years.
Springs that are not inspected and lubricated regularly fail without warning. When they go, the door either drops or stops moving entirely. That is both a security issue and a safety risk.
The same wear happens across all the moving parts:
- Rollers wear down and create drag on the track
- Cables fray and can snap under load
- Hinges loosen and cause the door to sit unevenly in the frame
- Tracks collect debris and fall out of alignment
- Opener chains and drive belts stretch and slip
None of these are freak failures. They are the predictable result of a mechanical system that has not been looked after. The difference between a garage door that lasts 15 years and one that causes problems at year three is almost always maintenance.
New Zealand conditions make it worse
Canterbury winters push hardware hard. The temperature can drop to near zero overnight and climb past 20 degrees by afternoon on a nor’wester day. Those swings put metal springs, tracks, and fixings through constant expansion and contraction cycles.
Coastal Canterbury and parts of Auckland face salt air on top of that. Salt accelerates corrosion on steel components, particularly the bottom seal, springs, and any exposed fixings. A door that has not been properly maintained in these conditions shows it quickly. Binding in the track, surface corrosion, panels that start to warp at the edges.
A well-maintained garage door handles all of this. One that has been ignored does not.
What to do and when
You do not need a technician for most of this. A basic routine keeps the door in good shape:
- Every six months: lubricate springs, rollers, hinges, and tracks with a purpose-built garage door lubricant. Not WD-40, which attracts dust and dries out quickly
- Once a year: check cables and bottom seals for wear or fraying
- Balance test: disconnect the opener and lift the door manually to the halfway point. A balanced door stays put. If it drops or rises, the springs need attention
- Auto-reverse test: place a piece of timber under the door and close it. The door should reverse on contact. If it does not, stop using the opener and get it checked
- After any nearby construction or dusty conditions: wipe down the track and check for debris
The whole routine takes under 30 minutes twice a year. It is the kind of thing that is easy to skip, right up until the door fails on a Sunday morning.
When to call someone in
Some things are not DIY. Get a technician out if you notice:
- The door moves unevenly or jerks on the way up or down
- There is a loud bang when the door operates (often a spring failure)
- Cables look frayed or have come off the drum
- The door will not stay in the open position when lifted manually
- The opener is straining noticeably or running slow
Torsion springs in particular are under high tension and should only be adjusted or replaced by someone who knows what they are doing. It is not a job to attempt yourself.
