Putting a deck in your garden will make it look smarter, neater – and make it easier to care for. It will also give you loads of new space for a dining area, space for seating or for kids to play.
Mark Out The Deck Area Mark out the position of the deck using pegs and string. Clear the site of grass and weeds; and level it with a spade. Lay a weedproof membrane and cover it with gravel. If you are laying your deck over an existing patio area you won’t need to do this.
Cut And Place The Joists Create the frame by cutting joists to the required size. The frame will be filled with floor joists; which should be 400mm apart at the centres. Mark their positions on the frame; and cut the floor joists to size. Place the side and floor joists in position in the garden.
Construct The Frame Make up the deck bearer of frame and floor joists. Use 70mm countersunk screws in pre-drilled holes; with three screws at each joist end. Use a spirit level to ensure all joists are level as you work.
Lay The Deck Boards Lay the deck boards. These run at right angles to the floor joists. Cut each board to the length required. Start with the first board at the front of the deck; ensuring it is flush with the outside edge of the frame. Use two 50mm countersunk screws in pre-drilled holes to secure the deck board to the deck bearer at each joist. Secure the remaining boards in the same way; leaving a 3-5mm gap between each board.
Finishing Use extra deck boards to face the exposed cut ends. Seal any cut ends of joists or boards with wood preservative to avoid rot.
