Chimney inspections are grouped into three levels by the National Fire Protection Association, and the level you need depends on your situation — not just how old your chimney is.
Level 1
A Level 1 inspection covers the readily accessible portions of the chimney, both inside and outside the home. It's the standard inspection for a chimney that's had regular use and maintenance with no known problems.
Level 2
A Level 2 inspection is more thorough and includes a camera scan of the flue interior. It's typically required when you're buying or selling a home, after a chimney fire, after an event like an earthquake, or if you're changing the type of fuel you burn.
Level 3
A Level 3 inspection is the most invasive, and may involve removing components of the chimney or nearby structure to access concealed areas. It's reserved for situations where a serious hazard is suspected and can't be evaluated any other way.
