Leaks are common. Extensive damage doesn’t have to be.

Water damage is one of the most common insurance claims. But well-placed flood sensors can help detect leaks early. This can help minimize water damage and reduce the cost of repairs in places where flooding is common, like near appliances connected to water lines or in basements prone to water seepage.
