Is composite decking worth the extra cost?

Composite costs about double pressure-treated wood upfront but needs almost no maintenance and lasts decades, so it often pays off over the life of the deck.

Does wood or composite decking last longer?

Composite lasts longer — 25–30+ years versus 15–20 for maintained wood — and resists rot and insects, while wood needs regular staining or sealing.

Wood vs Composite Decking | theHomework.ca

When building a deck, the big material choice is natural wood versus composite. Wood is cheaper upfront with a classic look; composite costs more but needs almost no maintenance.

Cost

Pressure-treated wood is the cheapest decking; cedar costs more for its looks and rot resistance. Composite (a wood-plastic blend) costs roughly double pressure-treated upfront, but you save on years of staining and sealing.

Maintenance and lifespan

Wood needs cleaning and re-staining or sealing every year or two, and lasts 15–20 years with upkeep. Composite needs only occasional cleaning, resists rot and insects, and lasts 25–30 years or more — its low maintenance is the main appeal.

Looks and feel

Many people prefer the natural look and feel of real wood, especially cedar. Composite has improved a lot and now mimics wood grain convincingly, stays splinter-free, and holds its colour, though it can get hot in direct sun.
