- Start in one corner of the sub-frame and position the first board across the inner joists. You want the deck board in the opposite direction to the inner joists, ensuring that it’s flush with the frame. Position any end-to-end joins between the deck boards halfway across an inner joist so you can screw both boards into the joist for stability. Make sure you keep a gap of between 5-8mm to allow for expansion of the wood.
- Begin to screw your deck boards to the joists. You’ll need to secure the deck board to every joist is covers along your deck frame. Use two screws for every joist. Mark where you’re going to add your screws, ensuring that they are at least 15mm from the end of the board and 20mm from the outside edges. Drill pilot holes for the screws, being careful to only drill through the deck board and not the joist. Then screw the decking screws into the holes.
- Continue to screw in the deck boards, ensuring you leave the correct expansion gap. You can stagger the deck board joins across the deck for more strength.
- Sand down any cut ends if you need to before applying decking preserver to protect the timber from rotting.

Wooden Decking in Penysarn
Wooden decking is an increasingly common choice for creating outdoor seating areas in gardens. Because of the natural beauty of wood, they can be very elegant spaces which you can use year round by adding outside heating and lighting. Wooden decking is typically installed in locations in front of patio or French doors where they can create a seamless transition between inside and outside spaces. Wooden decking is available in virtually any size or shape to suit any area. Curved designs or large areas joined by pathways can create a stunning effect. Wooden decking is reasonably easy to install and causes little disruption, especially when compared to other possibilities like patio or paving. It could even be installed over the top of a pre-existing patio. It is crucial however to make sure that your wooden decking is structurally sound and able to take the load of any furniture or plants that you want to use on the decking. There is a collection of species of wood that can be used in wooden decking. Typically decking is constructed from hardwood, but there are softwoods available that fulfil the durability requirements. As hardwood decking will demand maintenance, which commonly will involve yearly cleaning and staining for weather proofing, composite woods are becoming more popular for use in wooden decking as they are stronger and require significantly less maintenance.

FAQs
If your deck isn’t going to be flat to the ground, it’s a good idea to have some kind of balustrade to avoid any tripping. If the gap between the deck and the ground is less than 600mm, use a 900mm balustrade. If it’s higher than 600mm, the balustrade should be 1100mm tall.
- If you’ve not got an overhang or it’s a fixed deck, fit starter clips along the outside edge of the frame and secure with screws provided with the composite decking. If you are working with an overhang, put the first board into position not exceeding 25mm. If you’re adding a fascia, put an off-cut of board under the overhang so you know it’ll be flush with the fascia.
- Pre-drill all fixing points, measuring in 30mm from the edge of the board. Secure the board to the joist below with composite decking screws.
- Slide a hidden fastener clip in so it sits within the groove of the deck board. It needs to be in the centre of the joist to keep the boards secure and ensure an expansion gap of 6mm. Tighten the clips until just tight, and repeat so there’s a clip at every joist.
- Add the next board, ensuring that the fastener clips sit within the groove – make sure you don’t force it. Repeat step 3.
- Continue steps 3 and 4 until you’re at the final board, which you should secure in the same way as you did the first.
