The most water damage prone places in Charleston are downtown for a twenty mile radius. This is mainly due to the type of soil and the closeness to the Cooper, Ashley, and Wando rivers. Outside of downtown Charleston, areas that are in danger of high amounts of water damage are West Ashley, North Charleston, Hanahan, and northern Daniel Island.
The worst flooding in Charleston history was from Hurricane Hugo in 1989 that tore through downtown and annihilated most beach front property. Although it is rare to have a category 4 hurricane like Hugo, it is still a risk living in the southeast coast.
People living in water damage prone locations need to have the proper flood insurance to cover any costs of damage ranging from destroyed insulation to flooded basements. Sink holes can also be a cause of concern in these areas because of the high water table and unstable weather conditions.
If you have experienced water damage in one of these areas that is beyond a home repair, make sure you call a disaster restoration specialist in Charleston.
