Wooden Decking in Portsmouth

Wooden decking is an increasingly fashionable option for providing outdoor seating areas in gardens. Because of the natural beauty of wood, they can be very elegant areas that can be used year round by adding outside heating and illumination. Wooden decking is generally 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 suit any area. Curved designs or large areas connected by pathways can produce a striking effect. Wooden decking is reasonably quick 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 be sure that your wooden decking is structurally sound and able to take the load of any furniture or plants that you want to use on the decking. There is a range of varieties of wood that can be used in wooden decking. Normally decking is constructed from hardwood, but there are softwoods available that fulfil the durability specifications. As hardwood decking will need maintenance, which typically consists of yearly cleaning and staining for weather proofing, composite woods are becoming more popular for use in wooden decking because they are more robust and require much less maintenance.

Portsmouth is a significant city on the southern coastline of Britain and it is the 14th greatest urban area in the country.

Much of the city has long been rebuilt in the past six decades but we obtain a lot of requests for top tradespeople in Portsmouth all through the year in many household improvement categories.

FAQs

Can I fit a hot tub on my terrace or decking?

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.

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 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.
How to build a deck frame?
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
  1. Measure your deck frame and cut to size if necessary.
  2. 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.
  3. 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.
  4. Fit the coach screws with either a drill driver or socket and ratchet.
  5. 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.
