How to deal with insurance company's subornation claim that is way off

My dish washer leaked to my neighbor's floor. She has carpet and some laminate viynl damaged. However, her insurance company is asking us to pay for a full high end simulated wood laminated for it. They also claim changing the whole 500 sqft of the first floor which is a big area consider how much water can come out from a dish washer. The insurance company is trying to make a profit on us. I need an attorney to help me on fighting this greedy company.
