Wooden Decking in Hertfordshire

Wooden decking is an increasingly fashionable option for creating outdoor seating areas in gardens. Because of the natural beauty of wood, they can be very beautiful areas that can be used year round by adding additional heating and lighting. Wooden decking is usually fitted 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 virtually any size or shape to fit any area. Curved designs or large areas joined by pathways can create an impressive effect. Wooden decking is relatively simple 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 critical however to make certain 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 array 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 requirements. As hardwood decking will require maintenance, which commonly entails yearly cleaning and staining for weather proofing, composite woods have become popular for use in wooden decking because they are stronger and require far less maintenance.

FAQs

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.

How to fit composite decking?
Fitting composite decking is similar to installing timber decking, but there are some small differences in terms of the gaps you need to leave between boards and the screws you use. We’ll go through a quick guide to show you the process involved in fitting composite decking so you can decide whether it’s something you want to do yourself. Prepare the area Prepare the area according to our instructions in the previous FAQs – or you can use an existing patio or concrete base if you have one. Measure and mark out the area using chalk (if using an existing base). Assemble the decking frame Build the outer frame as we show in our FAQs above; if the area you have planned is longer than your joists, you’ll need to join them together. When you’ve built the frame and it’s secure, ensure that it’s at the right level for water runoff and add risers, slabs or treated off-cuts of timber at 500mm intervals if you need to. Add joists The spacing of your joists will depend on the type of design you have chosen for your composite decking. If you’re laying arched boards horizontally, you’ll need to space the joists 300mm apart. Lay your composite decking boards
  1. 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.
  2. 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.
  3. 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.
  4. Add the next board, ensuring that the fastener clips sit within the groove – make sure you don’t force it. Repeat step 3.
  5. 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.
Add a fascia board If you’re adding a fascia, measure in 40mm from each end and add two guide marks: one at 40mm from the top and the other at 40mm from the bottom. Connect the marks, then mark at 300mm intervals down the board. Drill pilot holes, then put the fascia board into position. You need to make sure that there’s a 40mm ventilation gap between the bottom of the fascia and the ground. Ask someone to hold the board level until you’ve finished securing it with composite decking screws; you can get colour-matched ones so they don’t look unsightly at the end of your decking. Not so sure you want to carry out such a big project yourself? Get quotes from decking pros who will be able to fit composite decking much more quickly and easily.
