@GoBucks96 sorry about the delay. Nothing has changed with foundation. Meanwhile, I have reached out several contractors and basement/foundation companies.
Ohio Basement Authority and and Basement Doctor both said about 5 piers should be installed - total cost around $10k (that hurt while typing).
Another contractor came in and said it is going to cost around 3500. He is not going to install piers. Since the house is 15 years old he said the ground should have automatically settled. He thought the drain line probably leaks or is broken. I plan to check that with a hose this weekend. He also pointed out that the corner blocks should not have broken as they did. They are hollow and the code requires them to be poured/filled with concrete.
Dominion is coming to take a look at it on 11/10. My question is, how can I verify if the corner blocks conform to ohio code. I googled but could not find anything specific. I can use this as leverage in my argument with Dominion.
I live in Marysville, OH.
