Professional Composite Deck Builders

Installing composite decking requires precise construction methods to ensure the system performs correctly over time. Unlike timber, composite boards expand and contract with temperature changes and must be installed using the appropriate fixing systems and spacing.

Northern Decking Co installs composite decking using correct framing structures, hidden fixing systems where appropriate and expansion allowances that allow the boards to move naturally. This ensures the finished deck maintains its appearance and structural integrity over many years.

By combining proper subframe construction with modern composite materials, we deliver decks that are both durable and visually appealing.

Composite Decking Designed for WA Conditions

Homes across Perth’s northern suburbs experience intense UV exposure, coastal winds and salt air. Composite decking performs particularly well in these conditions because it is engineered to resist moisture, fading and insect damage.



Modern composite boards are manufactured using a blend of recycled materials and durable polymers, creating a decking surface that is highly resistant to weathering. This makes composite decking a practical choice for coastal suburbs such as Alkimos, Mullaloo and Yanchep where outdoor structures must withstand challenging environmental conditions.


With correct installation and ventilation, composite decking can maintain its appearance and performance for many years.

Perfect for Perth


Composite decking is well suited to a wide range of outdoor applications and is particularly popular for modern homes and entertaining spaces.


Composite boards provide a clean, modern finish that integrates well with contemporary outdoor designs.

Common composite decking projects include:

• Alfresco entertaining areas
• Backyard entertaining spaces
• Pool surrounds
• Rooftop or elevated decks
• Deck replacements for older timber structures

Where Composite Decking Works Best

Benefits of Composite Decking

Composite decking offers several advantages for homeowners looking for a durable and low-maintenance outdoor surface.


For many homeowners, the reduced maintenance requirements make composite decking an attractive long-term investment.

Key benefits include:

• Strong resistance to fading, moisture and insect damage
• Consistent colour and finish across the deck surface
• Modern appearance suited to contemporary homes
• Long lifespan when installed correctly

Composite Deck Replacements

Many homeowners across Perth’s northern suburbs are choosing to replace older timber decks with composite alternatives. Over time timber boards can warp, split or require ongoing maintenance to maintain their appearance.


Northern Decking Co can assess your existing deck structure and determine whether it can be resurfaced with composite boards or if a full rebuild is required. In some cases, the existing structural frame can be retained while the decking surface is upgraded to modern composite materials.


This approach can transform the appearance of an outdoor space while reducing ongoing maintenance requirements.

Frequently asked questions

  • Is composite decking better than timber?

  • Does composite decking get hot in the sun?

    Like most outdoor surfaces, composite decking can warm in direct sunlight. Modern boards are designed to minimise heat absorption compared to older composite materials.

    When installed correctly, composite decking can last many years with minimal maintenance.
