I will be laying a new deck on old hardwood joists, the joists are pretty sound and I recon there is between 6 and 10 years left in them. However, I don't want to contaminate the new deck in any way from any residual wet rot (even though I will be treating the joists) I was thinking about plastic DPM between the boards and joists but am wary of moisture being retained under the boards, does any one have any cheap alternative to this that would allow a small air gap?
