Just wanted to express my thanks for your excellent website and numerous helpful documents - there seems to be a huge volume of differing (and often conflicting) information / comment about decking online, so I’m delighted to have found a reliable source without a commercial agenda.
I’m about to undertake a DIY decking project on a larger scale than my previous (largely successful) efforts, and your publications will give me valuable guidance - not to mention reassurance. Much appreciated!
DeckMark and CladMark quality assurance schemes
Our DeckMark and CladMark accreditation schemes verify the quality and longevity of products; the suppliers of such products; or the high standards of an installer. We have an ever-growing list of TDCA members who hold this status - search for them HERE.
Both of these schemes require the business to have a full audit and assessment prior to any accreditation being awarded. Those businesses that do not meet the standards are advised on how they might improve, in order to achieve accreditation in the future.
The DeckMark scheme has the full endorsement of the NHBC.
Thanks ever so much for all your help and for getting back with info so quickly. I appreciate that very much, thank you. It's so good to be able to talk to people who give sound advice and can guide you to good suppliers.
