Composite decking has become a popular choice for homeowners who want a low maintenance and durable option for their outdoor spaces. Two options that offer high quality are DesignBoard and Millboard composite decking, both of which are supplied by London Stone.

So, how long will composite decking last?

The answer depends on several factors, such as the quality of the product, the installation process, and the care and maintenance of the decking. Let's take a closer look at DesignBoard Classic and Millboard composite decking and what they offer in terms of longevity.

DesignBoard

DesignBoard Classic is a unique blend of PVC and rice husk fibres that creates a durable and long-lasting material that can withstand the elements. This composite decking comes with a 10-year warranty against structure and surface finish, which is a testament to its quality and durability. The decking is resistant to warping, splintering, and fading, making it a great option for outdoor areas that experience high foot traffic. It is also resistant to stains and scratches, which is a significant advantage for families with children and pets.

Millboard

Millboard Composite Decking, made from a blend of minerals and polymer resins, offers a range of products that emulate the look and feel of traditional timber decking while providing the durability and low maintenance benefits of wood-free materials. Millboard composite decking comes with a 25-year warranty against structure and surface finish.

Ensuring longevity

Both DesignBoard and Millboard will last much longer than their guarantee, however, with care. They are designed to withstand the elements and provide homeowners with long-lasting, low-maintenance decking solutions but longevity is not just dependent on the product itself. The installation process and ongoing care and maintenance are also critical factors that can have an impact on composite decking lifespan.

Installation

Installation best practices are essential for ensuring the longevity of decking. DesignBoard comes with an exclusive hidden clip system that allows for easy installation. It's important to allow for expansion and contraction of the decking material as it reacts to changes in temperature and humidity. Millboard is secured in place with its exclusive “lost head” Durafix screws.

Ventilation

Proper ventilation is also crucial for the longevity of composite decking, as it prevents moisture build-up and mould growth, which can cause damage to the surface and construction.

Cleaning and maintenance

Regular cleaning and maintenance are also essential for prolonging the look of your composite decking. Both DesignBoard and Millboard recommend cleaning your decking regularly. Avoid using harsh chemicals or abrasive cleaners as these can damage the decking surface. In conclusion, composite decking can last for decades with proper care and maintenance. DesignBoard and Millboard are both excellent options that offer high-quality, durable decking solutions. With a warranty against structural defects and surface finish, both products provide homeowners with peace of mind that their investment will last for years to come.
