Wooden Decking in Merton

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 fashionable spaces which you can use year round with the addition of external heating and light. Wooden decking is usually installed in locations in front of patio or French doors where they can create a seamless transition between interior and exterior spaces. Wooden decking is available in virtually any size or shape to complement any area. Curved designs or large areas joined by pathways can produce an attractive effect. Wooden decking is fairly simple to install and causes minimal disruption, particularly in comparison to other possibilities like patio or paving. It can even be installed over the top of a pre-existing patio. It is vital however to make sure that your wooden decking is structurally sound and capable of taking the weight of any furniture or plants that you want to use on the decking. There is a collection 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 generally includes annual cleaning and staining for weather proofing, composite woods have become popular for use in wooden decking because they are stronger and require significantly less maintenance.

Merton

The London Borough of Merton is a borough in south-west London, England. The borough was formed under the London Government Act 1963 in 1965 by the merger of the Municipal Borough of Mitcham, the Municipal Borough of Wimbledon along with the Merton and Morden Urban District, all formerly within Surrey. The borough derives its name from the historic parish of Merton, which was centred on the location now referred to as South Wimbledon. The local authority is Merton London Borough Council.

As outlined by population estimates made during 2014, the borough includes a permanent population of about 203515 inhabitants. The borough is also served by a number of London Tramlink stops from Wimbledon, which goes to Croydon, New Addington, Elmers End and Beckenham. It is the only London Borough which has tube, rail and tram services.

The principle commercial centres in Merton are Mitcham, Morden and Wimbledon, of which Wimbledon is the biggest. Other smaller sized centres consist of Raynes Park, Colliers Wood, South Wimbledon, Wimbledon Park and Pollards Hill. Every year, Wimbledon, one of the four tennis Grand Slam tournaments, is held at the All England Lawn Tennis and Croquet Club in Church Road Wimbledon. The event takes place over a fortnight at the end of June and beginning of July and it is the biggest annual sporting event to take place in the UK, attracting over 200000 guests in the course of the Wimbledon fortnight.

FAQs

How much maintenance will a wooden deck need?

Properly installed wooden decking will not need a lot of maintenance. Most manufacturers recommend regularly brushing leaves and dirt off the deck, and a yearly cleaning and staining procedure. This will keep the wood in the best condition. Fluids and treatments are readily available from all DIY shops and stores.

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 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 decking on a slope?
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.
