Composite Decking vs Timber

Timber is cheaper on day one. In a climate as wet as ours, that advantage rarely survives the third winter.

Composite Decking vs Timber

Upfront cost

Softwood is roughly half the material cost of a quality capped composite. Hardwood closes the gap considerably. Labour is broadly similar because the substructure is identical.

Lifespan and maintenance

Softwood needs annual treatment and typically wants replacing within ten years here. A capped composite board carries a 25 year warranty and needs washing, nothing more. Over twenty years, composite is comfortably the cheaper surface.

Lifespan and maintenance

Grip and algae

This is the Cumbrian argument. Untreated timber under trees becomes genuinely slippery. Capped composite resists algae because there is no exposed grain for it to colonise, and modern grain-embossed surfaces grip well when wet.

Appearance

Timber has a warmth and movement that composite cannot fully imitate, and it silvers beautifully if you accept that. Composite holds its tone permanently. Choose timber if you love the material; choose composite if you love the space.
