Talk about standing behind your product! Our 20-something-year-old Trex deck was failing, so the Trex company provided us with all new decking material (much improved from their original product).
Marlene and I decided to take on the replacement of the decking ourselves, but found significant structural water damage along the way. So, we basically rebuilt most of the underlying deck as well. Being ten feet off of the ground, this was not an easy task.
Miraculously, we were blessed with nearly a month of perfect, sunny fall weather. And, as an added bonus, I have found deck building to be a great weight loss program.
