Is there any information anywhere that could tell me how long it takes wood to rot. Specifically, the sub- floor on our addition was built with many code violations. There is no ventilation and only TWO inches space below the joices to the dirt. As a result, our floor has begun sinking and inspection revealed that the wood has rotted severely. I was wondering how long it takes for that process to happen, as be prepare for visits by structural engineers, inspectors and a construction attorney. Thank you! Please email!
