Additional coverage provided by the homeowners policy. The insurer will pay for any reasonable costs incurred by the named insured to protect his or her insured property from further damage, if the cause of loss is a covered peril. This is additional coverage and does not affect the limit of insurance applicable to the covered property. This concept is referred to as the "sue and labor clause" in most commercial property and marine forms.
