  • How do I install the decking?

    Please refer to our installation guidelines here.

  • How far apart should the supporting joists be?

    The supporting joist below the composite decking boards should be a maximum of 400mm apart. For further information on installation please see our installation guide.

  • Do you have a Composite Decking Brochure?

    Yes certainly, Please click here to download the PDF version. Or contact us directly to have a printed version posting.

  • Are the decking boards reversible?

    We advise the boards to be laid small groove side up. You may wish to lay them differently hower you may experience increased slippage and colour change when laying the boards differently, and this is done at your discretion. Whilst you can fit them either way up we recommend installing the multi-groove side up, the reverse side will be less slip resistant and will show stains and water marks far more when fitted with the multi groove side facing down.

  • Will I get a colour difference with my decking boards?

    Our composite decking boards are produced in batches and made from 60% recycled hardwood making this a natural product. For this reason slight colour variations may occur (more noticeable when purchasing different lengths of boards or when laying the boards “wide groove up”) We advise purchasing decking boards in the same lengths to avoid initial colour difference. Although we will always endeavor to pick all products from the same batch, when orders are added or amended at a later date the boards will likely be from a different batch therefore colour variation is likely. Please ensure you order the correct amount of boards on the initial order.

  • Can I amend/add to my decking order once I have placed it?

    Yes you can however please note this may slow the delivery process down. Delivery estimates are from the most recent order/amendment date.

  • What size drill bit should I use with the decking T Clip system?

    We advise using a PH2 drill bit with the T Clip screws.

  • How long does Composite Decking last?

    We offer a ten year warranty on all our boards meaning you get peace of mind with your new decking. We anticipate when looked after well composite decking will last well in excess of the ten year warranty.

  • How much is composite decking vs wood?

    Our composite decking boards are competitively priced against similar boards in the UK. Composite decking requires very little maintenance meaning your time can be spent enjoying it rather than on expensive repainting or staining. The cost of timber can vary where as our composite decking boards are priced low to stay low.

  • Can you paint a composite deck?

    Our Composite Decking is available in a range of attractive colours which are designed to last, meaning you don’t need to paint them or stain them. The boards are designed to be the colour they were originally so we would not advise painting them, only occasional cleaning to maintain their high end look. However, If you feel the need to re-paint your composite decking this is possible but you will need to ensure use a high quality Composite Wood Stain.

  • Will there be water marks on my decking?

    Water stain marks can show on any composite decking boards. In our time we have seen two types of water stains; both of which will generally disappear with exposure to a reasonable soaking of rain and general weathering. Water stains from wood tannins will occur in the early life of your deck as the natural tannins come out of the wood fibres at the surface of the composite decking. This will happen in the early weeks of your deck, and will depend on how exposed to the elements your deck is before the weathering process is complete. This type of stain can be more prominent when new decking is exposed to direct sunshine in the first few months of its life. Water stains from water pooling or dripping can happen on composite decking just like it can with many other materials/surfaces such as timber decking, glass, laminated floors etc. This can leave a “shoreline” effect. The visibility of the stain will be governed by factors such as how dirty the deck is and how quickly the water dries from the water pooling, clean as mentioned above. Again this can be exaggerated in hotter weather. Both types of marks/stains will disappear naturally over time unless, of course, you have a recurring problem that allows water to continually land on to the composite decking. I.E. A drip from a gutter will continue to make marks until the water is stopped from landing onto the water stained area. Our advice is to let the composite decking weather naturally over time and sort itself out. However, we understand you want to be proud of your new deck once installed and if you feel the need to try and remove the marks yourself then a wash with clean, hot water will wash away most marks. Do not wash your decking whilst it is hot. 1. Pour clean, hot water on the deck and let it sit for 5-10 minutes 2. Work in with soft bristle brush 3. Pressure wash (at low pressure without and wide fan) / rinse down with hot water (preferred) 4. Squeegee water off the deck with a squeegee brush 5. Mop up any wet areas with a clean sponge mop If water marks have been long standing they may require more hot water or repeated procedure.

  • Why is wooden decking called timber decking?

    Essentially, once a tree is cut down its no longer referred to as wood, its known as timber. This is quite often shouted by the person cutting the tree.

  • What’s the difference between C16 timber and C24 timber?

    C16 and C24 represent two different types of softwood timber, these numbers differentiate how quickly the timber was taken from a growing tree.

    C16 timber is taken from trees which are grown much faster than regular trees, because of this forced processes the timber can have more knots in the wood than slower grown timber. This process of fast growing and increase in knots can also make the timber less dense meaning it is weaker and not as durable as C24. The longer a tree takes to grow the denser and stronger the wood will be.

    C24 timber is approximately 50% stronger than C16 timber, this means it is more appropriate for longer spans or heavier loads. A C24 joist can bear more weight than a C16 joist thanks to the increase strength and durability within.

  • Should I choose tanalised or not tanalised timber?
    Tanalised timber in the UK is wood which has been pressure treated with chemicals to act as a barrier against weathering such as rot or against insect infestation.
    Cladco Timber Joists are high-pressure green treated with Tanalith ‘E’ preservative meaning you have peace of mind when using these externally.

  • If you cut the timber joists are they still graded as C24?

    No, if you cut the timber in the cross section or thickness then the strength of the material is altered, this means both sections of timber would need to be re-graded before use.

  • What does FSC certified mean and should it matter if it doesn't have it?

    Any responsibly sourced timber will be FSC-certified. All Cladco composite products and timber products are FSC certified. When you see the FSC logo a product, you can buy with confidence that you are helping to ensure forests are alive for generations to come. View our accreditations page
