40% of small businesses never reopen after a flood. 25% of survivors fail within a year.
The Insurance Gap
NFIP coverage caps at $250,000. For modern or coastal homes, the "out-of-pocket" cost for high-end finishes is often $100k+.

In extreme cases involving intense, sideways driving rain, some water could potentially find a way in between the barrier and your door. If this happens, the amount of water that gets trapped in this space is usually marginal. However, it is a very small volume compared to what a storm surge would bring, and there are several highly effective ways to minimize and manage it so your property remains fully protected. Every home is different, which is why our flood experts are available to walk you through the best techniques for your specific setup and offer custom-tailored solutions to give you that extra layer of protection and prevent water from getting through.
