Re: Tongue Groove Porch Fix or Rebuild?
I would say that T&G deck/flooring is a specialty item that a big box isn't likely to have. Call around to a few lumberyards and specialty trim shops. If you've got a supplier who specializes in vintage home materials or salvage, try them first.
I'm with Jack, I would replace just the few boards that need replacing, it will be far easier and cheaper than redoing the whole deck. If you go this route, we can tell you how to replace the boards with little effort.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
