Water in floor vents after heavy rain. I had water in my floor vents after a heavy rain last summer. Have gotten to estimates on running ducts through ceiling.

Was wondering if putting cenemt trough the entire house was necessary and if i need to get additional. What is the best way to fix this situation. The other one said they only fill the actual vents.
