had house leveled. Three months later noticed my sheet rock was shifting and cracking at an alarming rate. Found I had a leak under house. Got my leak fixed. And I'm needing to know how long it will take for the mud under house to dry. It's been three weeks house has not settled back yet. Looked under house and noticed that there was plastic laid out all inunder my house. Will that keep it from drying out and if so do I need to remove it. How long does this take to dry out. Spent a lot of money getting house leveled and it's worse now than before. They said when it dries house should settle back to normal. Is this true?
