Provide context
Share the fireplace manufacturer and previous installation records if available. Ground-level photographs can help explain the enclosure, but do not climb or remove top components to measure them yourself.
Assessment questions
Ask whether the cover, penetrations and adjacent parts will be evaluated together. If replacement is recommended, clarify fitting, material, installation details and compatibility with the listed fireplace or venting system.
Avoid cosmetic assumptions
Visible rust or staining warrants assessment; its appearance alone does not establish the extent of hidden damage. Ask the provider to distinguish confirmed findings from areas that require further access.
Before approval
Confirm whether the proposal includes the chase cover only, the chimney cap, enclosure repairs or more than one component.
