Quote from Jim Bilyeu
If your only getting 10 to 15 years life out of a deck, somthing is wrong. Maby your seeing the effects of using bleach and just not knowing it. Bleach speeds up the degrading process, not blow it up.
I just happened to be looking at this website last night
it is from the this old house website.
Pressure-Treated Wood
Advantages: Economical and plentiful, pressure-treated wood lasts around 15 years when properly treated with a water repellent every two years.
Everyone has their oppinion I guess.
Mine comes from asking the deck building contractors in my area and research on the web.
