Quick answer: choose timber for lower upfront cost, a natural look and easy privacy; choose aluminium for near-zero maintenance, rust-free durability and coastal or pool sites. Timber is cheaper to install but needs re-staining every few years, while aluminium costs more upfront and then you essentially fit it and forget it. For most inland Auckland boundaries timber wins on value; near the coast or around a pool, aluminium usually pays off.
Both are excellent fences when installed properly — the right pick comes down to your budget, your site and how much maintenance you're willing to do. Here's how they compare on the things that actually matter.
Cost: Upfront vs Over the Life of the Fence
On day-one price, timber almost always wins — a treated-pine paling fence is one of the most affordable solid fences you can build. Aluminium panels cost more to supply and install, so if you're comparing quotes purely on the initial figure, timber looks the clear winner.
The picture changes over 20–30 years. Timber needs re-staining every few years and may need the odd paling or post replaced, whereas aluminium's powder-coat finish just needs an occasional wash. Once you add up years of stain, brushes and weekends, aluminium's lifetime cost often lands close to — or below — timber, especially in harsh coastal conditions where timber weathers faster.
Maintenance, Looks and Privacy
Timber gives a warm, natural appearance and makes full privacy easy — close-boarded palings leave no gaps to see through. The trade-off is upkeep: it needs cleaning and re-coating to hold its look and resist rot. Aluminium offers a sleek, modern profile in a range of powder-coat colours and shrugs off rust and salt, but standard slat spacing means it's less private unless you choose a close-board or louvre style.
So the look you want matters as much as the material: timber for a traditional, fully private boundary; aluminium for a clean contemporary line and minimal fuss. Many homeowners even mix the two — an aluminium feature fence at the street with timber down the side boundaries.
Which Suits Your Auckland Site?
If your boundary is coastal, around a pool, or somewhere you simply don't want ongoing maintenance, aluminium is usually the better long-term call — it won't rust in salt air and meets pool-fence requirements neatly. If you want maximum privacy on an inland section at the lowest upfront cost, timber is hard to beat.
There's rarely a single right answer for a whole property, which is why we assess exposure, privacy needs and budget on site and often recommend a combination. A free quote is the quickest way to see which works best for your section.
Frequently Asked Questions
Yes, upfront — aluminium costs more to supply and install than a treated-pine timber fence. Over the fence's life the gap narrows, because aluminium needs no re-staining while timber does, so lifetime costs can be similar, especially near the coast.
Aluminium generally lasts longer because it doesn't rust or rot, comfortably reaching 25–30+ years. Timber can last 15–20 years when built with H4 in-ground posts and maintained, but it weathers faster if neglected or in salt air.
Standard slat aluminium leaves small gaps, so it's less private than solid timber. Close-board or louvre aluminium styles give strong privacy while keeping the low-maintenance benefit, though they cost a little more than open slats.
