Wooden Decking in Cardiff

Wooden decking is an increasingly prevalent option for creating outdoor seating areas in gardens. Due to the natural beauty of wood, they can be very fashionable areas which you can use year round by adding outside heating and illumination. Wooden decking is usually installed in locations in front of patio or French doors where they can create a smooth transition between interior and exterior spaces. Wooden decking is available in virtually any size or shape to accommodate any area. Curved designs or large areas connected by pathways can create a stunning effect. Wooden decking is relatively quick to install and causes minimal disruption, particularly in comparison to alternatives like patio or paving. It can even be installed over the top of an existing patio. It is crucial however to make sure that your wooden decking is structurally sound and capable of taking the weight of any furniture or plants that you would like to use on the decking. There is a selection of species of wood that can be used in wooden decking. Typically decking is made of hardwood, but there are softwoods available that fulfil the durability specifications. As hardwood decking will need maintenance, which commonly requires yearly cleaning and staining for weather proofing, composite woods have become more popular for use in wooden decking as they are more robust and require significantly less maintenance.

FAQs

How much maintenance will a wooden deck need?

Properly installed wooden decking will not need a lot of maintenance. Most manufacturers recommend regularly brushing leaves and dirt off the deck, and a yearly cleaning and staining procedure. This will keep the wood in the best condition. Fluids and treatments are readily available from all DIY shops and stores.

How to make steps for a deck?
Unless you built a ground-level deck, you’re going to need steps to go with it. Check Building Regulations to see if you need to install handrails as well. It’s good practice to:
  • Have a step tread width of 900mm – if you don’t want them that wide, they should be no less than 760mm
  • Add a central step riser to stairs wider than 900mm to prevent them buckling
  • Add a step depth (the vertical distance between each step) of between 150 and 180mm if building your own riser, so the steps are at a comfortable depth
Getting started To build your steps for the deck, you’ll need:
  • Step treads (the actual step themselves)
  • Step risers
  • Coach screws
  • Deck screws
  • Saw
  • Drill
Make the steps for your deck
  1. Make sure the ground where you want to put your steps is level and firm. If it’s not, consider laying concrete or paving slabs to provide a secure surface for your steps to sit so they don’t sink.
  2. Grab some joist off-cuts and cut them to the same width as your step treads. Attach them to the step risers at the top and bottom using countersunk coach screws.
  3. Place the steps against the sub-frame of the deck; if you’ve put slabs down for support, make sure the steps sit in the middle of them. The longest edge of the stair riser should be on the slabs, and the short edge against the deck. Drill pilot holes through the step and sub-frame joist, then screw the step to the sub-frame with more coach screws.
  4. After drilling pilot holes, screw the treads into the risers at each end with deck screws.
  5. If you don’t want gaps between each stair, you can add joist off-cuts or deck boards. Measure the height and depth of the gap, then screw the off-cut or board into the step riser with two screws at each end.
What should I do if my deck or terrace is slippery?

Usually, slipperiness is caused by algae or dirt on top of the deck or terrace. A full cleaning treatment should restore the natural grip of the wood or stone. If slipperiness is a persistent problem, consider installing grip mats in high traffic areas of the deck.

How to lay decking on uneven ground?
There are two ways to lay decking on uneven ground. We’ve explained how to build a raised deck in our FAQ ‘How to build a raised deck’ above, and that’s great for uneven ground or sloped gardens. But there’s another way that you can lay decking on uneven ground if you don’t want a raised deck: you can create a level supporting base. We’ll go through the basics here. Materials you’ll need
  • Paving slabs – old or cheap ones are fine
  • Timber for the frame and legs
  • Type 1 MOT hardcore
How to lay decking on uneven ground
  1. Mark out the area as we explain in ‘How to lay decking’. Then, dig to 200mm below where you want to surface of the decking to be.
  2. Add a 50mm layer of hardcore and make sure it’s compact.
  3. Build the decking sub-frame as we describe in ‘How to build a deck frame’.
  4. Lay out paving slabs along the edges and in the centre of the area. This will help to spread the weight of the decking.
  5. Set the decking frame on the slabs, checking for high or low points and adding off-cuts of timber where needed. Don’t forget to sand and seal these off-cuts with decking preservative.
  6. Add your joists and then the deck boards, leaving the recommended gaps of expansion of between 5-8mm.
Building your decking on top of paving slabs is a good way to get it level, but you still may not be able to get as good a finish as if a professional did it. If you’re in any doubt, get in contact with some decking specialists and see what they would recommend.
