A U.S. senator is enlisting the help of Pennsylvania insurance commissioner to help protect the Keystone State’s homeowners from sinkhole damages. In a letter to Pennsylvania Insurance Commissioner Michael Consedine, U.S. Senator Bob Casey (D-Penn.) asked that all new homeowners in the state be made aware that sinkhole insurance is not part of a standard homeowner’s benefit in Pennsylvania. The lawmaker says homeowners should also be given specific information on how to purchase that insurance.
