Local risks
What causes water damage in Wilmington
Older foundations and pipes
In a city where 66% of homes were built before 1960, the usual suspects are corroded supply lines, cracked cast-iron drains and foundations that let water in after heavy rain.
Apartments and shared walls
Renters occupy about 54% of Wilmington's homes. In multi-unit buildings, water from one unit travels through floors and shared walls, so report leaks to the landlord or association in writing right away.
Tropical and coastal storms
Remnants of Atlantic storms bring heavy rain and flooding, especially near the Christina and Brandywine.
