Should you use green lumber for your next construction or renovation project? Like most options for building materials, the answer is: “it depends.” Green, or “wet” lumber is called that way because it’s freshly-cut wood that hasn’t been kiln-dried or otherwise treated to remove moisture. It has a moisture content greater than 19%. The main reason why builders and contractors might recommend using it is that it can be considerably cheaper than your average lumber.
However, green lumber can also cause some issues down the road. All wood dries itself out to a certain extent. As the wood dries, water moisture and other liquids are released, and the wood starts to shrink. This process could cause mold to grow in the lumber before it’s even used for construction. It can also cause nails to pop and can cause framing to become warped or gapped. In certain climates, green lumber can be worthwhile. But, like most things, it’s important to consult a professional before making final decisions.
