My Englewood area basement flooded when the sump pump failed. Is that covered?

Only if the policy carries the water backup or sump overflow endorsement, and that is a policy question with a yes or no answer your agent or the claim line can give in one call. Standard homeowners policies commonly exclude ground water and sump overflow without it. If the endorsement exists, the cleanup is documented as an overflow event, photographs of the pit and the water line, the failed pump kept, not discarded, and the drying log attached. If it does not exist, the honest path is owner funded cleanup now and the endorsement added this month, because in the creek side streets that need sumps, the pump will be tested again.
