Wooden Decking in Thornhill

Wooden decking is an increasingly prevalent choice for providing outdoor seating areas in gardens. Because of the natural beauty of wood, they can be very beautiful areas which you can use year round with the addition of outside heating and lighting. Wooden decking is commonly installed in locations in front of patio or French doors where they can create a seamless transition between inside and outside spaces. Wooden decking can come in any size or shape to fit any area. Curved designs or large areas joined by pathways can produce an attractive effect. Wooden decking is reasonably simple to install and causes little disruption, especially in comparison to other possibilities like patio or paving. It can even be installed over the top of an existing patio. It is essential however to make sure that your wooden decking is structurally sound and able to take the weight of any furniture or plants that you would like to use on the decking. There is a variety of types of wood that can be used in wooden decking. Commonly decking is constructed from hardwood, but there are softwoods available that fulfil the durability specifications. As hardwood decking will require maintenance, which typically involves annual cleaning and staining for weather proofing, composite woods are becoming popular for use in wooden decking because they are stronger and require much less maintenance.

FAQs

How much is decking?
How much decking costs depends on the type of material you go for, how big you want your decking to be and where you live in the country. But typically, the cost of decking is between £1,200 - £1,800. The most popular material for decking is pre-treated softwood, which will set you back around £1,000 for 15m2. Hardwood is more expensive but is more durable, and will cost approximately £2,000 for the same amount. Homeowners are also beginning to choose composite decking, which is made from recycled plastic and wood fibres, and is low-maintenance and eco-friendly. This will cost around £1,600 for 15m2, while uPVC which is also a low-maintenance option costs around £600. People tend to choose composite over uPVC because it looks more like natural timber. If you’re a competent DIYer, you might want to have a go at laying decking yourself which will set you back around £1,000 for a standard softwood timber deck. We think it’s worth paying the extra £600 for a professional to lay your decking, since they will be able to do it much more quickly. If you do want to try it yourself, we recommend leaving at least a whole weekend open to do it, but it’s likely to take you longer. Factor in the possibility of having to take time off work to complete it and it might be more cost-effective to leave it to the pros.
How much decking do I need?
How much decking you need will – of course – depend on how big you plan your deck to be. There is an equation to help you work out how many deck boards you need. It’s a little complicated until you’ve been shown how it works, but once you know how to do it it’s easy to work out how much decking you need for any project. The equation takes into account the recommended 10% wastage and includes the expansion gaps that are required, which is between 5-8mm along the length of the deck boards (EGL, or expansion gap length) and 3mm along the ends of the deck boards (EGW, or expansion gap width) for timber. It also assumes you’re laying your decking horizontally, as if you’re looking for a diagonal or chevron design you’ll need more deck boards. Let’s go through an example, assuming you have a 10m x 6m area that you want to cover with decking made from timber boards that are 2.4m long and 144mm wide. We’ll use the EGL of 5mm and EGW of 3mm.
  1. Calculate the surface area for your decking Multiply the length (L) of your decking area by the width (W): L x W = Decking Surface Area (DSA) in m2 10 x 6 = 60m2
  2. Work out the coverage of your deck boards Add your deck board width (DBW) to the expansion gap length (EGL), then add the deck board length (DBL) to the expansion gap width (EGW). Then multiply these numbers. (DBW + EGL) x (DBL + EGW) = Single Board Coverage (SBC) 0.144m + 0.005m = 0.149m 2.4m + 0.003m = 2.403m 0.149 x 2.403 = 0.358m2
  3. Calculate the number of deck boards you need Multiply the SBC by 1.1 to allow for 10% wastage. Then, divide the DSA by the SBC. DSA / SCB x 1.1 = Total number of boards required 60m2 / 0.358m2 x 1.1 = 184.36 boards – so round up to 185 so you’re not left short.
If that all seems a bit complicated for you, let a professional do the maths – they will be able to give you an idea of how much decking you’ll need in no time.
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.
How to lay decking?
Laying simple, ground-level decking may sound intimidating, but it doesn’t have to be. With careful planning and preparation, you can lay decking that you’ll be proud to show off to neighbours, family and friends. Here are a few tips to get you started. Plan carefully Draw out a plan, to scale, on paper. This will help you to know how many boards you’ll need and ensure that you don’t end up having to cut anything to fit. Prepare the area Measure out the site according to your plan and hammer a peg into each corner, then tie string around each peg to help you see what you’re working with. If you’re not laying on existing slabs, dig into the ground, lifting out turf if it’s there, and check that the site is level. Then add concrete slabs for more stability or lay weed-control fabric over the ground and cover with gravel to further prevent weed growth. Build your sub-frame Since a lot of people ask this, we’ve got a more detailed guide in the FAQ below. Lay your deck boards
  1. 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.
  2. 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.
  3. 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.
  4. Sand down any cut ends if you need to before applying decking preserver to protect the timber from rotting.
Although this is a simplified set of instructions, it’s enough for you to see whether you want to attempt to lay decking yourself – and if you don’t, you can get in touch with professionals who will be happy to give you a quote.
