A chimney requires both a cover and a cap, but these parts often get confused with one another.

A chimney cap is a piece that sits above the flue to prevent animals, debris, and water from entering the flue.

You might be able to turn a normal door into a fire-rated door, but you’re better off purchasing one that meets all NFPA 80 standards. If you want to DIY a normal door into a fire door, you’ll need a self-adhesive intumescent seal, metal hinges, fire-resistant glazing, and a self-closing device, but you’re always better off buying a certified fire door.

Certified fire door inspectors should inspect fire doors. These professionals receive training to specifically assess the condition, functionality, and compliance of fire doors. They often hold credentials from groups like the Door and Hardware Institute (DHI) or the International Fire Door Inspector Association (IFDIA). While fire marshals won’t usually do hands-on inspections, they’ll check that doors are being maintained properly during routine safety audits. If a building relies on fire doors for code compliance, it needs someone who understands the details—the difference between a cosmetic issue and a safety failure—and standards to sign off with confidence.
