Avoid! I spent a small fortune with Ecodeck. I have a small (1metre) section amongst a large area of decking where the sun beats on the planks for most of the day - the planks have warped and bowed beyond belief. On contacting them on 3 occassions they simply say 'they are not fitted correctly' - if this is the case then why are all the other planks perfectly fine. They simply will not admit I must have had a substandard pack OR the product cannot withstand the heat. I would have been happy with even some replacement planks at a reduced rate as this would have made me see this company in a good light BUT they just will not accept ANY responsibility. They could have easily avoided this bad review but they are clearly a different outfit once you have paid them. Avoid them and their product its sh*te.
