I recently purchased a townhome that came with a deck. While it did pass inspection and is structurally sound, the deck is very weather beaten and could use a face lift. Many of the nails have started to pop up, some of the railings are a bit loose and my black lab has taken a liking to chewing on some of the railings. All of this being said, we have decided to re-do the deck. We were going to upgrade the stairs, railings and decking itself to trex composite decking. My question is, as long as it is structurally sound, so I need to replace the whole frame for the deck, or may I just utilize the same frame and replace floorboards, railings, etc. Thank you for your assistance.
