Composite Decking Explained: Costs, Benefits and Care

Timber decking is cheaper to buy but needs annual maintenance to stay safe and attractive, and it can splinter, warp and rot over time. Composite boards are made from a blend of recycled wood fibres and plastic, so they resist rot, fading and insects and never need painting.

For families and busy households, the appeal is obvious: a deck you can enjoy rather than maintain.

Composite boards cost more per metre than softwood, but the gap narrows once you factor in years of stain, sealant and replacement boards you would otherwise buy. The total price depends on the deck size, height, sub-frame and any steps, balustrades or built-in features.

Maintenance is genuinely minimal — an occasional sweep and a wash with soapy water keeps composite decking looking its best. There is no annual sanding or re-oiling to schedule.
