All you need to know about quality deck design, installation & materials
The Timber Decking and Cladding Association (TDCA) is an independent organisation. We are a technical and advisory body that operates on a not for profit basis. We provide decking advice including guidance on how to correctly specify and install timber decking and timber decking care and maintenance. The organisation also has a cladding sector. This website is all about timber decking. If you are interested in timber cladding please visit Timber Cladding Home.
We advise you to use DeckMark accredited materials and / or professional installers to help ensure that your timber decking is long lasting and durable. DeckMark is the quality scheme operated by the TDCA. Please go to the suppliers section to access a list of DeckMark approved wood decking companies.
Our deck calculator app provides deck builders with a quick and simple means of quantifying the materials needed to produce a pressure treated softwood deck. Aimed at professional and DIY installers, the app can be downloaded free from iTunes.
