Standard homeowners policies exclude damage caused by water that backs up through a sewer line or floor drain. If your basement floods because your sump pump fails or the municipal sewer backs up into your floor drain, you're typically on your own without a specific endorsement.
Why This Claim Is So Common
Water backup claims are among the most frequent and expensive home insurance claims. Finished basements, laundry areas, and lower-level living spaces are the most common loss locations.
What the Endorsement Costs
The endorsement that covers this is usually called 'water backup and sump overflow' coverage. It's added to a standard homeowners policy for a modest premium: - Cost: often $50-150 per year - Coverage: typically $5,000-25,000 depending on the option you select
North Carolina's Specific Risk
In North Carolina, summer storms and heavy rains create real sewer and drain overflow risk, especially in older neighborhoods with aging infrastructure. This isn't theoretical exposure.
