My deck covering has worn away as shown in attachment. The covering was not reccomended anyway because it harboured damp. Under the carpet like cover are boards. The deck is some 9 feet above ground level supportd by posts. How can I renovate the surface? I would like to use standard decking wood but I am new to decks and would I have to remove the boards, or could the decking be fixed to the boards? What products might be suitable? Also the other attachment shows the deck rails which could also do with replacement. Any idea how involved this project might get for a non professional?
