It all starts with ProGuard, a comprehensive residential cleanup and replacement program for owners of aboveground heating oil tanks. Introduced by The Powderhorn Agency in 2001, ProGuard has grown to be the largest program of its kind, relied on by more than 60,000 full service residential customers across the U.S. In addition to proactive tank replacement assistance and other benefits, this program provides customers with up to $50,000 in the event of an aboveground tank release. ProGuard is available for Residential and Manufactured Housing Community customers. Please choose below for more information.
