Redwood Verses Pressure Treated Lumber

We are in the process of replacing our old deck and was surprised to see that the redwood decking and rim joists were still in very good shape, but most of the pressure treated lumber was rotted and termite infested. Is pressure treated lumber that inferior to redwood when it comes to rot and termite infestation?

I know that redwood cost about twice as much as pressure treated lumber, but I think I may go with redwood for all the deck components if it is that superior to pressure treated lumber.

Thank you for taking the time to read my post.

Are you sure that the rotted material is pressure treated fir? I doubt it.

Either way, pressure treated douglas fir is far superior to today's redwood as far as decay resistance.

Thumbs up

Thanks, I stopped by the local lumber yard the other day and they were surprised also. I will go with pressure treated Douglas Fir for all the interior joists and beams.
