A cover assembly is provided for an enclosure, such as an electrical enclosure. The enclosure includes a panel member and a plurality of sides extending outwardly from the panel member to define an interior. The cover assembly includes an inner cover, at least one fastening mechanism fastening the inner cover to the enclosure, a trim member at least partially overlaying the inner cover, and at least one biasing assembly coupling the trim member to the inner cover. The at least one biasing assembly biases the trim member toward the inner cover, and is structured to bias the trim member toward an exterior surface of a structure, such as a building wall, to which the electrical enclosure is coupled.
