Despite only being a few hundred miles north of you, Redwood is nearly
unheard of around here. I did find a batch about 20 years ago for the deck
on our old mobile home. It held up well for over 13 years with bi-annual
maintenance, then I used the redwood lumber for a variety of woodworking
projects when we dismantled it to move the mobile home out.
For the deck on our house, I use pressure treated wood rated for ground
contact for the underlying structure. Then I used cedar deck boards
attached with stainless steel screws. I made the mistake of using a Behr
oil stain when we first installed it. Horrible product. Thankfully, one of
the advantages of going with cedar is that I could strip it and sand it
smooth again (don't try that with pressure treated). This time around I
used Sikkens "Teak" colored stain, which went on much nicer and should hold
up much better. It did wreak of oil for a few days though. :)
When I built a small deck for my in-laws, I also used ground contact PT for
the structure. However, their deck sits out in direct sunlight all day,
with no gutters to protect from constant roof run off, and I knew they
would not do any maintenance (they were in their 70's). I chose composite
decking for their application and it turned out really well. About two
years later the wood railing needs some maintenance, but the deck itself
looks like the day I installed it. Also, it has some texture which helps
keep it from getting slippery for seniors coming and going.
Composite costs a little more than cedar, but if you factor in the costs of
maintenance and restaining, it's probably comes out about the same. Of
course, while it can look really nice, it's still plastic. :)
