When choosing a new fence for your property, the two most popular options for Kiwi homeowners are timber and aluminium. Each offers unique benefits and drawbacks in terms of style, durability, maintenance, and cost. Whether you’re building in Palmerston North or anywhere else in New Zealand, the right material depends on your priorities and property layout.

This guide compares timber and aluminium fencing to help you make an informed decision.

Appearance and Aesthetics

Timber

• Offers a natural, classic look that suits traditional and rural homes
• Can be stained, painted, or left to weather naturally
• Ideal for full-privacy fencing and solid boundary walls

Aluminium

• Sleek, modern lines suit contemporary homes and urban builds
• Available in powder-coated colours and slat designs
• Often used in semi-private or decorative applications

Durability and Weather Resistance

Timber

• Treated pine or hardwood can last 15–25 years with proper care
• Vulnerable to rot, insects, and warping without regular maintenance
• Best suited to dry or well-drained sites

Aluminium

• Naturally rust-resistant and ideal for coastal or damp environments
• Won’t warp, crack, or rot over time
• Lifespan of 30+ years with minimal upkeep

Maintenance Requirements

Timber

• Requires regular staining, sealing, or painting every 2–3 years
• May need occasional board replacements due to damage or rot
• Prone to weathering and fading if left untreated

Aluminium

• Virtually maintenance-free—occasional wash-down with water is sufficient
• No need for painting or sealing
• Great for homeowners seeking low-maintenance fencing

Cost Comparison

Timber

• Lower upfront cost (especially for treated pine)
• Hardwood and feature fencing styles increase pricing
• Ongoing maintenance costs should be factored in

Aluminium

• Higher upfront investment than pine, often comparable to hardwood
• Long-term savings from reduced maintenance and longer lifespan
• Excellent value for modern builds and premium aesthetics

Environmental Considerations

Timber

• Renewable material when responsibly sourced (FSC-certified)
• Can be reused or recycled in part
• Some hardwoods may be imported from unsustainable sources—always check

Aluminium

• Often made from recycled materials
• Fully recyclable at end of life
• Requires more energy to produce initially, but offset by longevity

Security and Privacy

Timber

• Solid construction provides excellent privacy and noise buffering
• Easily customised for height and coverage

Aluminium

• Slatted designs provide visibility and airflow but less full privacy
• Often integrated with automated gate systems for added security

Best Use Cases

• Choose Timber If: You want full privacy, natural aesthetics, and don’t mind ongoing maintenance
• Choose Aluminium If: You want low maintenance, modern styling, and superior durability in wet or coastal conditions

Final Thoughts

Both timber and aluminium fencing offer strong benefits depending on your needs. Timber is versatile, affordable, and traditional—but it comes with maintenance demands. Aluminium is sleek, durable, and maintenance-free, making it ideal for busy homeowners or homes exposed to the elements.
