Some commonly asked questions about composite decking

The life expectancy of a composite deck can vary depending on a number of factors, including the quality of the composite material, the level of maintenance, local climate conditions, the colours chosen, and how well it was installed. On average, you can expect a well-maintained composite deck to last between 25 to 30 years.

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 will put into deck maintenance.

Composite decking boards tend to retain heat when exposed to direct sunlight, making it warm to the touch, though not as hot as other materials such as pavers, tiles and concrete. The degree of heat retention can vary based on brand, colour, composition, climate, and sun exposure. Darker-coloured composite decking boards absorb more heat and can become warmer than lighter-coloured ones. To lessen heat buildup and maintain comfort, you can choose PVC deck boards, lighter-coloured boards, create shade with pergolas or outdoor rugs, or take advantage of cooler times of the day. While not all composite decking may not stay exceptionally cool, it offers the benefits of low maintenance and durability, making it a popular choice for many homeowners.

Some key points to consider when choosing a composite deck board:

Material Composition: Examine the composition of the board, as it can affect performance. Look for composite decking boards made from high-quality, recycled materials and durable additives for longevity.

Colour and Texture: Select a deck board that complements your outdoor space. Many options are available in various colours and textures; choose one that suits your aesthetic preferences.

Warranty: Check the manufacturer’s warranty. A longer warranty often indicates confidence in the deck board’s durability and performance. Some warranties can 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 like food, drinks, and mildew.

Board stability: Choose a brand and deck board that has a proven track record for its resistance to warping, cupping and splitting.

Price and Budget: Determine your budget and compare prices across composite decking boards and brands. While high-quality composite decking boards may be more expensive upfront, they often prove cost-effective over time due to their low maintenance requirements and extended lifespan.

Good quality composite decking is generally more expensive than traditional wood decking, but its long-term benefits make it more cost effective in the long run. When you remove the cost of sanding, acid washing and oiling that goes hand in hand with wood decking, composite decking is a much better option traditional timber decking over the long term. Add in its longer timespan compared to timber, and its an obvious better investment option.

Composite decking is known for its impressive resistance to fading. Unlike traditional wood decking that can lose its colour and vibrancy over time due to exposure to UV rays 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 that ensure your deck won’t succumb to the same fading issues that can plague natural wood. 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.

Composite decking can become slippery when wet, although the degree of slipperiness can vary depending on the specific brand, surface texture, and whether or not mould or mildew is present. Many composite decking 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.

When it comes to composite decking, there are many great options to choose from. Some of the top brands like Trex, Millboard, TimberTech, and Fiberon offer a variety of options to satisfy your preferences. Take into account factors like durability and aesthetics to help you make an informed decision. With a little research, you can find the perfect composite decking that aligns with your needs, budget, and local climate.
