Pressure Treated?
 

My wife has asked me a question about pressure treated wood. She has read online that old pressure treated wood is no longer available because of the preservatives used previously. She has asked me if my old decking is leaching out these old preservatives, and should replace my old decking...

(I wonder if she just wants a new deck?)

Any suggestions? Have they really changed the preservatives used?

I have heard that if you have an existing deck, with pressure treated wood, it poses no danger. Actually tearing it down could release more chemicals than leaving it in place! I will try and find a reference to this and post it...

I found a good FAQ page on pressure treated wood. It states that pressure-treated wood poses no danger when handled. You can read through the following web page: http://www.beanteam.com/faq2.html

she maybe just wants a new deck ;)

Like the above post states pressure treated wood shouldn't be a problem.

I used pressure treated wood on my deck. Didn't have any problems with it and don't know why they would have changed it. Can't imagine the expense of having to upgrade your deck to any changes though! Here is another site that gives you info on the subject, if you want to read up!

I'll quote a section that you might feel important:

I found a really good article on pressure treated decks. Thought I would share.

This problem has happened to me. I had an old porch (wood) and about a year ago I had gardens placed all around it. Well because of some odd chemical the deck leaked into the soil near it, no plants lived. So I got rid of that deck put in a new one and got some new soil...everything was fine. So going on that experience it may cause a problem for your gardens :D

Cca Lumber
 

The EPA still allows cca to be used to treat lumber, just not in sizes normally used for decking or playscapes. 2x6's & smaller can not be treated with cca, but 2x8's & up can be. Most 6x6's & large timbers are still treated with cca. Although you can get it for 2x8's it is not usually stocked by lumber yards & must be special ordered.

On a side not I used to buy my treated lumber directly from a treatment plant, the old boy that ran the place died of cancer some years ago.
