are existing joists for a new deck acceptable???
I'm going to replace my deck with something this summer (wood, composite, aluminum, not sure yet). After I pull off the old PT boards and remove the nails, should I in some way treat the existing 20 yr old joists before the new boards are attached? Such as fill in the old nail holes to minimize water infiltration? Of course, any major damage will be repaired but just wondering. I read others talking about filing nail holes, putting down waterproof membranes etc.
