Introduction to Composite Decking

Composite decking is a revolutionary alternative to traditional wood decking, blending wood fibres and recycled plastics. This concoction results in a robust, resilient material that stands the test of time, enduring the elements without succumbing to rot, insects, or fire.

Why Choose Composite Decking?

Composite decking is a sought-after choice due to its longevity, with a life expectancy of over 50 years and minimal maintenance requirements. It offers a seamless blend of aesthetics and functionality, providing the look and feel of wood without the associated upkeep.

Material Composition

Composite decking is a symphony of wood and plastic, combining the best of both worlds to create a durable and stable decking material. The wood fibres provide strength and a natural appearance, while the plastic components offer resistance to moisture and insects.


The use of recycled plastics in composite decking makes it an eco-friendly option, contributing to sustainability and reducing environmental impact. It’s a green choice for those conscious of their ecological footprint.

Expansion and Contraction

Like all materials, composite decking undergoes expansion and contraction due to temperature fluctuations. However, its stability surpasses that of wood, ensuring dimensional integrity over time. Proper installation techniques and maintenance practices are pivotal in managing these movements effectively.

Mitigation Strategies

Employing spacing strategies during installation and opting for quality fasteners can mitigate the effects of expansion and contraction, preserving the deck’s aesthetics and structural integrity.

Factors Affecting Expansion and Contraction

A myriad of factors, including ambient moisture, temperature variations, and ultraviolet light exposure, play a role in the dimensional changes of composite decking. The colour and shade of the boards also influence their thermal behaviour, with darker shades absorbing more heat.

Preventive Measures

Selecting light-coloured boards and incorporating shades can reduce heat absorption, minimising expansion and contraction. Regular cleaning to remove debris and moisture can also curb the effects of environmental factors.

Installation Techniques

Expert installation is crucial to maximising the benefits of composite decking. Professional builders leverage their knowledge of the material’s properties to construct decks that resist warping, bowing, and buckling, ensuring longevity and optimal performance.

Importance of Professional Installation

A well-constructed deck, built with consideration for the material’s behaviour, can withstand the elements and retain its beauty over time. Professional installation eliminates the risks associated with improper construction, providing peace of mind to homeowners.

Handling Repairs

Regular maintenance and prompt repairs are essential to maintaining the structural and aesthetic integrity of a composite deck. Addressing minor issues promptly can prevent them from escalating into major problems, ensuring the deck remains in pristine condition.

Maintenance Practices

Regular inspections to identify potential issues, coupled with routine cleaning to remove dirt and debris, can prolong the life of the deck. Using appropriate cleaning agents and avoiding power washing can preserve the finish of the boards.

Surprising Benefits Of Composite Decking

Benefits of Professional Services

Opting for professional services for the installation and maintenance of composite decking ensures adherence to best practices and optimal results. Professionals bring a wealth of experience and knowledge, ensuring the construction of a safe and durable composite deck.

Value Addition

A professionally installed composite deck not only enhances the aesthetic appeal of a property but also adds value to it. It’s a worthwhile investment for homeowners looking to improve their outdoor living experience.

Custom Design Options

Composite decking offers a plethora of design possibilities, allowing homeowners to bring their vision to life. The availability of various colours and patterns enables the creation of unique, aesthetically pleasing outdoor spaces.


The versatility of composite decking allows for personalisation, enabling homeowners to choose designs that reflect their style and preferences. Incorporating features like lighting and railings can further enhance the appeal of the deck.
