What is the Timber Decking and Cladding Association?

An independent and not for profit organisation, the TDCA acts as a technical and advisory body for the UK timber decking and timber cladding industries.

Assisting large commercial contractors in addition to individuals undertaking a residential project, we can advise on areas such as the correct specification of materials, installation guidance and ongoing care and maintenance of both timber decking and timber cladding. Indeed, the Association is recognised as a reliable and authoritative source of expert opinion in the UK.

DeckMark and CladMark quality assurance schemes

Developing an ever-growing list of TDCA approved suppliers and installers, we operate the DeckMark and CladMark quality schemes that demonstrate the high quality and longevity of the materials that have been approved or the high standards of the installer that has been accredited.
