Detailed Outside Chimney Inspection 20-Item Checklist

Wood framed chimney chase (C) Daniel FriedmanHere is a chimney inspection checklist built from multiple contributors.

Contact Us if you have corrections or additions for this chimney inspection checklist.

Watch out: no checklist can be complete, and you should never rely only on a checklist to perform a building inspection.

A checklist is useful to help avoid forgetting certain key steps, but it is always possible that other defects are present that are not on your checklist.

Readers of this outdoor chimney inspection checklist should be sure to review the illustrated chimney defect and inspection procedures at CHIMNEY INSPECTION from GROUNDCHIMNEY INSPECTION at ROOFTOP.

These articles on chimneys and chimney safety provide detailed suggestions describing how to perform a thorough visual inspection of chimneys for safety and other defects. Chimney inspection methods and chimney repair methods are also discussed.

We list these observations in a order (not the only possible order) that might be followed by a visual inspection beginning outdoors and continuing indoors throughout the building, basement to attic, and including appliances or devices that vent through a chimney.
