What affects the cost
- Size and layout: more area means more boards and frame; angles and borders add time.
- Boards: treated softwood costs least, composite more, hardwood more again. Composite saves years of staining and copes best with salt air.
- Height: raised decks need footings, bigger timbers, bracing, steps and balustrades.
- Groundwork: slopes, soft ground and drainage all add work before the frame goes in.
- Coastal fixings: stainless or coated screws and clips cost a little more but don't rust.
- Access: gardens with no side access take longer, as everything comes through by hand.
- Extras: glass screens and balustrades, lighting, built-in seating and removing an old deck.
Comparing quotes
Look for the board brand and range, the joist spacing and frame material, the type of fixings, how the deck meets the house and what's included for steps and waste. A cheaper quote with ordinary screws may cost more within a few winters by the sea.
