What the 3 Levels of Chimney Inspection Actually Mean
If you have scheduled a chimney inspection in Wheaton, you may have heard the term levels. The NFPA 211 standard defines three of them, and knowing the difference helps you understand what you are paying for.
Level 1: The Annual Check
A Level 1 is the routine inspection for a chimney in regular use with no changes. The technician checks the readily accessible parts of the chimney and flue for soundness, blockages and creosote. It is what most homeowners need each year, usually paired with a sweep.
Level 2: Sales, Changes and Events
A Level 2 is required when you buy or sell a home, after a chimney fire or weather event, or when you change fuels or add an appliance. It includes everything in a Level 1 plus a video scan of the flue and a look at accessible areas in attics and crawlspaces.
Level 3: Confirming a Hazard
A Level 3 is the most thorough and least common. It is used when a serious hidden hazard is suspected, and it may involve removing parts of the chimney or wall to confirm the problem.
Which One Do You Need?
For a yearly check, a Level 1. For a home sale or after an event, a Level 2. A good chimney company will tell you which level fits before starting, so there are no surprises.
Quick Questions
Do I really need a Level 2 to sell my house?
A Level 2 is the standard for a real-estate transaction because it documents the chimney condition with a video scan, which protects buyer and seller alike.
