Does homeowners insurance cover flooding in crawl space?

You always must determine the cause of the damage. What made the crawl space flood? If the cause is due to torrential rain then a homeowners policy will not cover this type of loss. What you would need here is a flood insurance policy. If for instance, a pipe burst, therefore causing the flooding of the crawl space, then the regular homeowner's policy will pay for the damages, except for the actual pay for the repair cost of the actual piece of the pipe.
