Click-Deck has a super website, easy to navigate, great video demo, and there is (real) help along the way should you need it. The system is brilliant - I covered some old tatty wooden decking with the black composite and it looks SO smart and neat now. It was easy to work out how much to order, the delivery came quickly and I could start laying it down immediately - only the ability to get on your hands and knees and some basic common sense required. So satisfying - DIY mindfulness! If cutting to size is required, it is easy with an electric jigsaw - unscrew just the section you need to cut, then trim away excess base with a Stanley. Low maintenance solution that has received much admiration. Measuring up for my next project already.
