It depends on the specific terms and conditions of your insurance policy. Most standard homeowners insurance policies do not cover damage caused by water or moisture, including groundwater seepage or flooding. However, some policies may offer optional coverage for these types of damages. Additionally, some policies may provide coverage for damage caused by the sudden and accidental discharge of water from a drain field, but not for damage caused by gradual leaks or wear and tear. It's important to carefully review your policy and speak with your insurance provider to understand the specific coverage you have.
