We recently moved into a 15 year old house which has a zero clearance wood deck on the back. I noticed that the dryer vent exhaust comes out of the house just under where the deck meets the brick on the side of the house. The deck boards were notched out slightly when it was built to make room around the vent. I was wondering if there is a problem or potential problem awaiting me with this setup. I found a Q & A from Tom Silva that says it's not really a problem, an outdoor deck is going to get wet anyway. As long as it's treated lumber, no problem. However, on a recent ATOH, Richard helps a customer fix a dryer vent and states that you don't want to vent out under a deck. So I'm confused whether it's okay or not.
The other issue is, I don't have much of anywhere else to go with it unless I want to drill another hole in the brick exterior. The house is on a crawlspace and the last time I was down there, I found the last owner had let the flexible duct line fall off and it was venting into the crawlspace. I fixed this with a new, flexible aluminum duct to at least get the exhaust outside, but now...curious about the deck issue.
