Composite decking costs more than timber on the day you buy it, and less than timber over the years you own it. That sentence is the whole decision in miniature, but it hides a few things worth spelling out before you spend a weekend and a good sum of money on a garden you will look at for the next twenty summers.
What composite decking actually is
Composite boards are wood fibre and recycled plastic pressed together, and the good ones are capped, which means the core is wrapped in a tough plastic shell. That shell is where most of the benefit lives. It does not rot, it does not splinter, insects have no interest in it, and it does not need oiling, staining or sealing, ever. You wash it and you use it. Over a season it will not go silver and it will not go green and slimy the way an untreated softwood deck does by its second autumn.
It also arrives looking like a finished product. The boards are embossed with a grain and coloured through the cap, so there is no waiting for stain to dry and no annual ritual to keep the colour.
The honest downsides
It is dearer up front, usually somewhere between one and a half and two times the cost of a softwood deck for the boards alone. A dark board also runs warm underfoot on a genuinely hot day, as any dark surface does, so if the deck is in full afternoon sun and the children go barefoot, lean toward a lighter tone. And a cheap, uncapped composite is a false economy: without the cap it can fade and stain much like the timber it was meant to replace. If you are going to buy composite, buy capped composite.
Where timber still wins
Timber is cheaper to get started, and softwood especially. It has a natural feel and smell that no plastic-wrapped board quite matches, and if you enjoy the yearly job of cleaning and oiling a deck, a timber one rewards it. Hardwoods like ipe are beautiful and genuinely long-lived, though they are neither cheap nor maintenance-free, since they still want oiling to hold their colour rather than weathering to grey.
The honest summary is this: timber is the better buy if you want the lowest price today, or if the look and feel of real wood matters to you more than the upkeep. For most people, neither of those is quite true once they think it through.
The ten-year maths
A softwood deck needs cleaning and re-treating roughly once a year to stay respectable, and boards that split or rot need replacing along the way. Add up the treatments, the odd replacement board and the weekends, and by year eight or nine the cheaper deck has usually cost more in total than the composite one, and it looks tired while the composite still looks like itself. That crossover is the reason we point most people at composite unless budget on the day is the deciding factor.
The quick way to decide
- You want to fit it once and forget it, with no yearly upkeep? Composite, capped, every time.
- Tightest possible budget this weekend, and you do not mind maintaining it? Softwood timber.
- Full-sun deck with barefoot children? Composite, but choose a lighter board so it stays comfortable underfoot.
