It's a better idea to tear out deck

Q. Is there a synthetic wood veneer that I could install over the top of my pressure-treated deck, or will I have to tear the deck out? The structure itself is still in good condition -- I just don't want the hassle of tearing off all the wood decking and taking it to the dump.

A. You can install composite deck boards over what you currently have, but there are some things to consider. Make sure the present deck has good drainage with large enough gaps between the existing deck boards to allow for water runoff. You'll have to install spacers between the current layer of decking and the new one to create an airspace that will help to prevent rot from occurring between the two layers.

Also consider how your current deck is attached to your house. The added thickness may end up being higher and may create a trip hazard at the exterior door. The truth is, even though you don't want to do it, you will be better off tearing out the current deck -- it's still cheaper than completely rebuilding. And don't forget, there are many recycling centers that now take lumber and may even pay you for it.
