Look for the DeckMark Symbol - the sign of quality for decking materials and installers.


DeckMark is a quality assurance (QA) scheme created for the Timber Decking and Cladding Association by BM TRADA Certification. The scheme is based on existing quality assurance standards - ISO 9000, EN45011/12, ISO Guide 62/65 and is intended to help all those engaged in the specification, design, installation or purchasing of decking to ensure that the products they buy or the TDCA registered contractor they commission will be of the highest quality.

To ensure standards of performance are maintained, the DeckMark accreditation of an individual firm is audited and renewed every 12 months by an independent inspector appointed by the TDCA.

The DeckMark QA scheme has two parts:

DeckMark  Part 1 is for PRODUCTS

For a list of quality assessed products and product retailers go to the Suppliers page

DeckMark  Part 2 covers the workmanship of TDCA registered decking INSTALLERS

For a list of quality assessed installation contractors go to the Timber Decking Members page
