The last times I have used PT 4x4 posts (fence posts, supports for an
overhang, and a deck) they have warped and twisted when drying to the
point where they look a mess and where structural integrity is
compromised. It normally takes 6-12 months to dry out and twist. My
question is, is cedar any better? I'm doing another deck and am
willing to pay the extra if it will stay straight.

I often wonder whether there is a case to go back to the lumber
retailer and seek compensation for the warpage. I'm sure the answer
is no (or at best they might give you a replacement piece, which is
nothing compared to the labor to fix it) but it isn't right.



*I have been using cedar for several years now for posts for mounting
lights, outdoor services and such. I will be doing a solar panel
installation soon and will use a cedar post for that. I have looked at the
pressure treated wood and I do not find it attractive. The cedar that I
have installed has not warped at all and continues to look good. Just this
week I purchased some 2"x6"x4' cedar pieces to mount some outdoor
receptacles on. The wood was just so nice looking compared to the PT and
since it was going to be at on an big estate I went with the good looking
stuff. I told the owner later how I was sealing the wood and she asked if I
got cedar and not PT. She was very happy.
