Question 1

How to build decking on a slope?

Accepted Answer

You might think that building decking on a slope is a no-go, but it’s actually a great way to help you make use of your garden when the ground is sloping. It will provide you with a level surface that you can BBQ on as well as dine alfresco without finding that your meal is rolling down the table. But how do you build decking on a slope? Our guide in the FAQ above, ‘How to build a raised deck’, is the perfect solution – but we’ll break it down here if you just want to get an idea of what’s involved. Dig out the area If you’re laying on soil or turf, you’ll need to dig it out. Dig down and remove all the turf from the area and ensure that there are no weeds or stones in the area you’re going to build your decking on. Since you’re building on a slope, it will be hard to get it level, but dig out to a depth of 50mm and lay weed-control fabric with gravel over the top. Add posts and set with concrete Make holes for posts and add them in, ensuring they’re longer than you need. Make sure they’re level, then fill the holes with a concrete mix to set them in place. Build the outer frame Make sure you always work at the top of the slope when you’re building your decking, and measure where the highest point of the decking will be. Secure the 4 sides of the outer frame and factor in a 2mm fall for every metre of decking so rainwater can run off. Add joists Secure joists along your frame at 400mm intervals. If you get to the last joist and there will be more than a 400mm gap left at the end, add in an extra one for support. Lay your deck boards Screw your deck boards to the joists, ensuring that the deck boards are running in the opposite direction to the joists. For timber boards, you need to make sure you leave an expansion gap of 5-8mm. These steps should give you an idea of whether you want to have a go at building decking on a slope, or whether you want to leave it to the pros.

Question 2

Do I need to tell my neighbours if I’m going to replace my fence?

Accepted Answer

It’s a good idea to talk to your neighbours before you start any work to avoid confusion along the way. But if the fence is definitely your responsibility and on your property, there’s no legal obligation to notify them. It’s also a myth that you need to erect a fence with the flush side without posts facing your neighbour’s property.

Question 3

How to build a raised deck?

Accepted Answer

Building a raised deck will take some time and is trickier than laying standard decking at ground level, but if you want to build decking on a slope or uneven ground it’s the best way to do it. If you do your research and follow instructions, you and a friend or family member can build a raised deck over a few days. Here’s a simplified guide of the steps you’ll need to take. Plan carefully It’s best to plan your raised deck by drawing it to scale on paper before you go and get supplies. This will help avoid wastage and making more cuts to timber than necessary. Prepare the area Prepare the area according to the instructions we give in the FAQ ‘How to lay decking’. However, because you’re building a raised deck, you’ll need to add posts: Place a post in the corner of the frame you created with the pegs and string. Measure and mark out 100mm from each side. Dig out this soil to a depth of 700mm (watch out for cables or pipes). You should have a 300 x 300mm hole. Repeat for the other 3 corners. Using a brick bolster, split a concrete block in two. Put a section of the block in each hole. Get a length of post longer than you need and place one in each hole. You can cut it down later. Create props on each post to hold them in place until you’re ready to add a cement mix. Check that they’re level. When you’re happy that they are, secure them in place with a concrete mix, making sure you create a slope in the concrete so that rainwater runs away from each post. When the concrete is set, remove the props. Create a string line around each corner post and find the centre point between each. Place a timber batten at each point, ensuring that they’re not spaced any more than 1500mm apart. Make the outer frame Working from the corner where the deck will be at its highest above ground level, measure and mark on the post where the highest part of the frame will be. Measure from the far side of one post to the opposite and cut sections of joist to size. Line up a piece of joist with the mark you made and temporarily secure it. Factor in a 2mm fall for every metre of decking so rainwater can run off. Secure the frame to the other corner post, ensuring it’s at the right level. Do this for every side of the outer frame. Using 100mm coach screws with washers hanging on the end, secure each end of the four sections of frame. Mark out where the centre of the support posts will be and secure all of these posts to the frame, except the centre post. Add your central support joists. These should run in the same direction as the deck boards will run. You’ll need to measure from the inside of the frame on one side to the inside of the frame on the opposite side. Attach the joist in the same way as you did for the other posts. Repeat so the centre post is in between two sections of frame and secure the posts with concrete. Trim down all the posts to the correct height using a saw. Add your weed-control fabric and weigh down with gravel across the entire area. Add your joists Measure 400mm from the centre of the outer frame and mark a line. This will be where the first joist is positioned. Repeat at 400mm intervals down the length of the frame – if the last one will be more than 400mm, add another joist to create enough support. Attach a joist hanger to each end of the joist. Place the joist in position so the centre lines up with the 400mm spacer mark. Secure using external grade screws once you’re happy that the joist is flush with the frame. Lay your decking boards Refer to our FAQ on how to lay decking to see how you should attach your decking boards. Remember: Always treat cut ends and pilot holes with decking preservative to keep your decking in good condition for as long as possible. Building a raised deck isn’t a straightforward task.

Question 4

How much decking do I need?

Accepted Answer

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.

Question 5

How much is artificial grass?

Accepted Answer

How much artificial grass costs depends on the quality of grass you choose, how big the area to be covered is, and whether you choose to have it installed or do it yourself. On average, you should expect to pay between £25 and £70 per m2 to have artificial grass installed by a professional. That means a 30m2 artificial lawn would cost between £750 and £2,100. So what will affect how much artificial grass costs? The quality of the artificial grass The quality of the artificial turf makes a big difference to the price. The lower end of the price range might not be quite right for a garden, since they often look extremely fake, and won’t last as long. Somewhere in the middle of the range should give you a good, long-lasting look without breaking the bank. Quality of the sub-base If you’re laying artificial grass on an existing lawn, this will need to be dug up to level out the area and add a weed-resistant membrane, creating what's called a sub-base. On average, the materials will cost £247 to make a sub-base. Whether you’ll need waste removal If you’re digging up the existing lawn or removing paving slabs to create a new sub-base, you might need a skip. A typical 4-yard skip will set you back around £220. Whether you’re doing DIY If you fancy having a go at laying your own artificial grass, you’ll of course save on labour costs. You’ll need to weigh up the benefits of DIY against the risks that the finish might not look as good or the grass might not last as long. But if you choose an average-quality artificial grass at £15 per m2, 30m2 of artificial grass will cost £450 not including the underlay as well as joining tape and adhesive.

Question 6

Do I need planning permission for fences?

Accepted Answer

Not if they are under 1 metre high if next to a road or 2 metres high elsewhere. It’s always recommended to check with your neighbours and the local authority if you are unsure. Other restrictions may apply, for example if a fence might impact driver visibility on nearby roads.

Question 7

How much is decking?

Accepted Answer

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.

Question 8

How do I find out who owns a fence?

Accepted Answer

Speaking to the owners of the neighbouring properties is recommended. If you are still unsure, you may need to check the original deeds to the property. Generally the rule is that you are responsible for the fence at the right hand side of your property.
