who is responsible for new damages after inspection contingency removal?

I assume that you are using the California Association of Realtors Residential Purchase Agreement to buy a single family residence.  I also assume that you have a real estate agent that is representing you as the buyer in this transaction.  Talk to your agent about this issue.  If he can't resolve it, talk to the real estate broker of record that employs your agent. Read your purchase agreement.  Paragraph 16 provides for a Final Verificaiton of Condition.  If the property is not maintained in the same condition as it was upon contingency removal, then your remedy as the buyer is to: (1) make a request for repairs to the seller; (2) get a credit from the seller for the costs of the repairs; (3) cancel the purchase.
