why choose composite

Modern Outdoor Living Without the Work

Composite decking has transformed how Sydney families enjoy their outdoor spaces. It gives you the natural look of timber but with technology that makes it perfect for our busy lives and harsh climate.

Zero maintenance headaches

No sanding, no oiling, no staining. Just occasional washing with soap and water. Spend your weekends enjoying your deck, not maintaining it.

Built for Australian conditions

Composite doesn't fade in harsh sun, won't rot from rain, resists mould and mildew, and stays cool underfoot even on hot days.

Safe for families and pets

The surface won't splinter, crack, or warp. Kids can run around barefoot, and your pets' claws won't damage the surface.

Looks authentic, performs better

Modern composite technology replicates real timber grain patterns and colour variations. Your guests won't know it's not timber.

Long-term value

While composite costs more upfront than timber, you'll save thousands over the years in maintenance costs and time.

FAQs

Common Questions

The life expectancy of a composite deck can vary depending on quality of materials, maintenance level, local climate conditions, colours chosen, and installation quality. On average, you can expect a well-maintained composite deck to last between 25 to 30 years. Many premium brands offer warranties of 25 to 50 years, giving you long-term confidence in your investment.

Composite decking is often considered a better choice for those who want a low-maintenance, durable, and long-lasting deck. On the other hand, timber decking is preferred by those who appreciate the natural look of wood, are willing to invest time in maintenance, or have a lower budget. The choice ultimately depends on your priorities, budget, and how much time and effort you're willing to put into deck maintenance. We're happy to discuss both options honestly and help you decide what's right for your situation.

PVC deck boards are usually cooler than timber deck boards. Trex Lineage, even though its a capped wood plastic composite, has a special coating that also keeps it cooler than timber deck boards.

Material composition: Look for boards made from high-quality, recycled materials and durable additives for longevity. Colour and texture: Select a board that complements your outdoor space with colours and textures that suit your aesthetic preferences. Warranty: Check the manufacturer's warranty. A longer warranty indicates confidence in durability and performance. Some warranties extend from 25 to 50 years or more. Resistance to fading and staining: Ensure the composite board is engineered to resist fading from UV exposure and staining from common outdoor substances. Board stability: Choose a brand with a proven track record for resistance to warping, cupping and splitting. Price and budget: While high-quality composite boards may be more expensive upfront, they often prove cost-effective over time due to low maintenance requirements and extended lifespan. We'll walk you through all these considerations during your consultation to help you make the right choice.

Composite decking can become slippery when wet, although the degree of slipperiness varies depending on the specific brand, surface texture, and whether mould or mildew is present. Many composite products are designed with textured surfaces to enhance traction and reduce the risk of slipping, and they are generally less slippery than timber decking. Proper maintenance and cleaning are crucial for retaining slip resistance. Millboard, in particular, offers excellent non-slip characteristics and is ideal for poolside applications.

Composite decking is known for its impressive resistance to fading. Unlike traditional wood decking that can lose colour and vibrancy over time due to UV exposure and weathering, composite decking is specifically designed to maintain its original appearance for the long term. The secret lies in using durable, colourfast materials, UV inhibitors and advanced manufacturing processes. While some minimal fading may occur over the years, it is far less noticeable than with traditional timber decks, allowing you to enjoy a beautiful, low-maintenance outdoor space that looks fresh and vibrant. All premium brands we install come with extensive fade warranties.
