Wooden Decking in Dorset

Wooden decking is an increasingly popular choice for providing outdoor seating areas in gardens. Due to the natural beauty of wood, they can be very elegant spaces which can be used year round by using external heating and light. Wooden decking is often 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 linked by pathways can produce an attractive effect. Wooden decking is reasonably simple to install and causes minimal disruption, especially when compared to alternatives 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 capable of taking the weight of any furniture or plants that you would like to use on the decking. There is a selection of types of wood that can be used in wooden decking. Often decking is made of hardwood, but there are softwoods available that fulfil the durability specifications. As hardwood decking will need maintenance, which usually will involve annual cleaning and staining for weather proofing, composite woods are becoming more popular for use in wooden decking because they are stronger and require far less maintenance.

Dorset

The county of Dorset can be found in the southwest of England having a large portion on the southern coastline. With a population of little more than 700,000 the county positions at 32nd in the UK with regard to region and has a small density of only 690 people per square mile mainly because of its relatively large land area. Dorset has a large number of older people residing in the county and a lower than average number of younger people. In fact, nearly 26% are of retirement living age; considerably larger than most of England and Wales. Irrespective of your age, when it comes to improving your home, make sure to work with vetted experts for a wonderful finish.

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.

Building a simple deck frame, or decking subframe, that you’re laying on level ground is easy if you take time to prepare and get all the things you need. We’ll go through the steps on how to build a deck frame here. Tools and equipment To get building your deck frame, you’ll need:

Decking joists
Coach screws
Coach bolts
Combi drill
Socket set
A saw suitable for your project and the thickness of the timber
Pencil
Decking preservative
Sandpaper or sander

Build your subframe

Measure your deck frame and cut to size if necessary.
Make 2 pencil marks on each end of the frame’s 2 outer joists to mark where the coach screws will go. They need to align with the centre of the adjoining outer joist. Then, use a flat wood drill bit to drill recesses into each mark. Make them the same depth of the screws that your using’s head and wide enough for a ratchet or socket to tighten them.
Using a thinner drill bit, line up the outer joists and drill a pilot hole through the middle of the recess. These pilot holes act as a guide for the screws and stops them from splitting the wood.
Fit the coach screws with either a drill driver or socket and ratchet.
Repeat the process for the inner joists once you’ve assembled the outer frame.

IMPORTANT: While you’re building your deck frame and the decking itself, remember to cover all pilot holes and ends of timber in decking preservative to ensure that your decking remains structurally sound for as long as possible. Though relatively simple, building a deck frame and the decking will take some time. It would be much quicker and easier to get a professional in to do it, who could represent more value for money.

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

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.
Add a 50mm layer of hardcore and make sure it’s compact.
Build the decking sub-frame as we describe in ‘How to build a deck frame’.
Lay out paving slabs along the edges and in the centre of the area. This will help to spread the weight of the decking.
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.
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.

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.
