My 82 year mother lives in a house where the floor is sinking in one
corner of the house. The basement floor is cracked and sinking along
the outer walls. The house walls and ceiling are plastered and I'm
afraid that the ceiling is going to come down.

I know there are many companies that claim they can correct the problem
and I'm a little leery.Any ideas as to the best way to correct the
problem and the cost associated with correcting the problem.

Thanks
