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 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. 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.

Wooden Decking in New Malden

Wooden decking is an increasingly popular option for providing outdoor seating areas in gardens. Because of the natural beauty of wood, they can be very fashionable spaces which you can use year round by installing external 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 can come in virtually any size or shape to complement any area. Curved designs or large areas joined by pathways can create an impressive effect. Wooden decking is relatively easy to install and causes little disruption, particularly in comparison to other possibilities like patio or paving. It could even be installed over the top of a pre-existing patio. It is vital however to make certain that your wooden decking is structurally sound and capable of taking the load of any furniture or plants that you would like to use on the decking. There is a array of types of wood that can be used in wooden decking. Commonly decking is made of hardwood, but there are softwoods available that fulfil the durability specifications. As hardwood decking will need maintenance, which commonly involves annual 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.

Building of residences went off with a slow start, starting to increase nearer the end of the 19th century and the beginning of the 20th century after the establishment of both 2 and three bed room terraced homes.

FAQs

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.

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
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
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.

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.

Yes, although you should make sure that the terrace or decking is able to support the weight of a hot tub. Usually, you will need to have a structural survey carried out on the area. Seek the advise of a hot tub retailer or installer about the logistics of installing one at your property.
