Why would a replacement foundation cost $100,000 to $200,000?
Because the First rule in Insurance Work is to add a ZERO on the end.
I honestly see no reason for even a full basement foundation to cost $100,000 let alone $200,000, unless it’s a very large house with a very elaborate foundation on a difficult lot.
Average cost to raise a house after Hurricane Sandy is about 100,000.
If they have to remove an old concrete foundation, add a bunch more.
