I'm looking at replacing the siding on my house and have a question. I have the siding that is 4x8 sheets of fiber board, where if moisture gets in it, it tends to swell out. Around the corners and covering the horizontal joints is cedar boards. Under the siding is just the 4x8 sheets of 1/2" foam board.
What would be the best way to put up Vinyl or Cement fiber siding? Should I take off the existing siding and put up a house wrap? Or should I replace the bad sheets and put up siding on top of it?
