Hello, I am looking into purchasing a property by a river. It is an older house and lifted off of the ground. There are Bald Cypress trees on both sides of the house and I can see the knees of the trees spreading to under the house. However, I can’t see the condition of the knees under the property, and the water lines travel under the house. Has anyone seen cases where the knees grow up under an elevated property and cause damage to the plumbing and flooring?
