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.

A properly built and maintained deck using treated doug-fir should last twice that long. A deck properly built and maintained using cedar or redwood should last three times as long.

I don't think people would spend 30, 40, 50 thousand dollars to have a deck built if they knew it was only going to last 10 to 15 years. The deck I have on my home is 22 years old and it looks almost as good as it did the day I built it. Sorry, I just can't buy the 10 to 15 year stuff. I have never used bleach and I never will, it's a cheap fix with a long term problem.
