The
Three Levels of Inspection
The National Fire Protection Association (NFPA)’s 211 (Standard for Chimneys, Fireplaces, Vents, and Solid Fuel Burning Appliances) is the standard upon which we base our services. This standard classifies chimney and venting system inspections into three levels—Level I, Level II, or Level III. Each level of inspection has a specific scope of work and specific criteria.
Level I Inspection
This inspection is recommended when the chimney and venting system is easily accessible and when the homeowner is planning to maintain its current use. In general, this is the level of inspection performed in most homes. In a Level I inspection, we verify that the chimney structure is sound and that the chimney is free of obstructions and combustible deposits, such as creosote.
Level II Inspection
The addition of a new home heating appliance or a change in the type of fuel a homeowner is burning requires a Level II inspection. This inspection level is also required upon the sale or transfer of a property or after an operating malfunction or external event that is likely to have caused damage to the chimney. The scope of a Level II inspection includes that of the Level I inspection plus the inspection of accessible portions of the attics, crawl spaces, and basements. It may also include a performance test such as a smoke test or a pressure test, and possibly an interior chimney video inspection if recommended.
Level III Inspection
When a Level I or Level II inspection suggests a hidden hazard and the evaluation cannot be performed without access to concealed areas, a Level III inspection is recommended. This type of inspection confirms the proper construction and condition of concealed portions of the chimney structure and the flue. Level III inspections are generally necessary when investigating an incident that has caused damage to a chimney or building, or where a hazard is detected and suspected.
Both the Chimney Safety Institute of America and the National Fire Protection Association recommend yearly chimney inspections to help prevent fires and carbon monoxide poisonings.
