I had a brand new deck installation and a balcony replacement (both cedar) done when I moved into my home. I was impressed by how quickly the project was completed and also by how great it looked. But within 7 years this cedar deck was full of carpenter ants. When a contractor pulled up the boards, he found far too much wood in contact with soil, not properly constructed to allow the wood to dry out and no air space. I have to admit I had not watched the construction and really would not have known what to look for if I had watched. Literally thousands of carpenter ants came from one rotten board that was pulled out. The 7 year old deck ended up in a dumpster and a new deck had to be constructed. That is a short life expectancy for a cedar deck and an expensive lesson learned.
