I have a customer who built a deck on the back of his house. The deck is about 8 feet off the ground. The house sits up on a hill and gets a fair amount of wind. The problem is that when the wind hits the side of the house it is forced up underneath the deck and blows upward. The result is what I call the beer bottle or jug effect. Somehow either the gap between the deck boards is just right or there's some kind of gap somewhere in the joists and a low pitched howling noise results. Any suggestions? The contractor/homeowner that built the house is calling it a design flaw in the deck board and wants the manufacturer to pay for replacement materials and labor.

HELP!

Just a thought. Could you nail lattice under the deck to the floor joist. A lattice lid. It might break the wind enough to stop the jug effect but still allow it to drain and dry out.
