i have a house that is up on blocks. the problem is that the dirt under the house goes right up under the floor. i know there is supposed to be a space for air flow, but there isn't. i know that one option is to get the house raised up, which i have recently found that i can't afford. so, another option is to dig the dirt from underneith the house and put a drainage system in. my question is: who in the world do i call to have dirt removed from under my house? i really need to do this quickly, because it is causing termite problems.... please let me know anything you can!!!
