Good Afternoon...

I have an 18'X36', kidney shaped pool with the standard (i.e. UGLY) white coping around the edge. I'm thinking about expanding my pool area and re-doing my deck. I'd like to do a cantilever deck, but would rather not replace the lining, as there is nothing wrong with it. Is that easy to do, or is it something that would require me to replace the liner? Any and all feedback offered is greatly appreciated. Thank you.

John
