We have a split level where the finished lower level windows are at ground level. We flooded during a heavy Noreaster storm (the water was coming up through the foundation) and had to rip out our wall-to-wall carpeting. Before we replace the carpeting, we need to assure this flooding won't happen again. Who should I be asking to come inspect the reason for the flood and suggest solutions?

I would hire a good home inspector. This person will be working for you, not trying to sell you something as with a basement water proofing company, etc. Ask for recommendations from a trusted real estate agent. They will have someone they like to work with and will know whether that person is good at their job or not. Hope that helps. Good luck. You weren't the only one to get water in that insane storm.

I agree with the answer above. That would be my first route to go.
