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 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. 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. 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. Add the next board, ensuring that the fastener clips sit within the groove – make sure you don’t force it. Repeat step 3. 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.

Wooden Decking in Launceston

Wooden decking is an increasingly fashionable choice for providing outdoor seating areas in gardens. Because of the natural beauty of wood, they can be very fashionable areas which can be used year round by using outside heating and light. Wooden decking is often fitted 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 any size or shape to match any area. Curved designs or large areas linked by pathways can create a striking effect. Wooden decking is fairly quick to install and causes minimal disruption, particularly when compared to alternatives like patio or paving. It could even be installed over the top of a pre-existing patio. It is essential however to be sure that your wooden decking is structurally sound and able to take the load of any furniture or plants that you would like to use on the decking. There is a choice of varieties of wood that can be used in wooden decking. Usually decking is made of hardwood, but there are softwoods available that fulfil the durability specifications. As hardwood decking will demand 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 more robust and require far less maintenance.

Launceston

Launceston is a town, ancient borough, and also civil parish in Cornwall, England, United Kingdom. It is 1 mile (1.6 kilometres) west of the middle stage of the River Tamar, which constitutes almost the entire border in between Cornwall and Devon. The landscape of the town is generally steep especially at a sharp south-western knoll topped by Launceston Castle. These gradients fall down to the River Kensey and also smaller sized tributaries. The town centre itself is bypassed as well as is no more physically a primary highway. The A388 still runs through the town near to the centre. The town remains figuratively the "gateway to Cornwall", because of having the A30, one of the two double carriageways into the county, pass straight next to the town. The other twin carriageway and alternate main point of access is the A38 at Saltash over the Tamar Bridge and was completed in 1962. There are smaller points of entry to Cornwall on small roads. Launceston Steam Railway narrow-gauge heritage train runs as a visitor attraction during the summer season. It was restored for visual and commercial heritage objectives as well as runs along a short country path, it is preferred with visitors however does not compete much of the year. Launceston Castle was built by Robert, Count of Mortain (half-brother of William the Conqueror) c. 1070 to control the surrounding area. Launceston was the caput of the feudal barony of Launceston and also of the Earldom of Cornwall until replaced by Lostwithiel in the 13th century. Launceston was later on the county town of Cornwall until 1835 when Bodmin replaced it. Two civil parishes serve the community and also its borders, of which the main more built-up administrative unit housed 8,952 residents at the 2011 census. Three selecting wards include referral to the town, their total population, from 2011 census data, being 11,837 as well as 2 clerical parishes offer the former single church, with three churches as well as a big swathe of land to the north as well as west part of the area. Launceston's motto "Royale et Loyale" (English translation: Royal and Loyal) is a recommendation to its adherence to the Cavalier cause during the English Civil War of the mid-17th century.

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.

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.

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.
