i need to know how to go about fixing my front sill of my house that has termite damage. my house is very low to the ground and i will have to do it from the inside of my house by tearing up my floor. i was wondering on how do i support the house and with what, or do i need to dig and hope that there is no floor joice damage to raise the house. it is a very old house and i am sure that there is damage in the walls too. if anyone can help. thanks angie
