I have a basement wall that was cracked due to roots from a tree. The tree has since been removed , but structurally a home inspector said the wall inside needs to be taken care of. There are no leaks presnetly but there is a bulge in the wall and the (joists) where it contects to the room above are out of alignement. How can I have this repaired as inexpensively as possible without compromising the future safety of the room above. Thabk so much. Kathie from Chatham
