The TDCA operates DeckMark and CladMark quality schemes which verify the performance and longevity of materials that have been accredited or the high standards of the installer that has been approved.
These schemes require a full business audit and assessment to achieve accreditation which are maintained through ongoing audit checks.
Choosing a TDCA accredited supplier for your timber decking or cladding ensures that you are using the best quality to deliver a long-lasting result.
