Chimney inspection levels 1, 2 and 3, explained

The national chimney standard describes three levels. Here is what each one includes and when you need it.

Level 1: the yearly check

For a chimney that is in regular use with no changes. It covers the accessible parts of the chimney, the firebox, the damper and the visible flue, and checks for blockages and buildup. This is what most homes need once a year, ideally with a sweep.

Level 2: when something changes

Everything in Level 1 plus a camera run through the full length of the flue and a look at the accessible attic, crawl space and roof areas. Get a Level 2 when you buy or sell a home, change the fuel or the appliance, after a chimney fire, earthquake or storm damage, or when a Level 1 finds a problem that needs a closer look.

Level 3: when hidden damage is suspected

Level 3 means removing parts of the building or chimney to reach concealed areas. It is only needed when a Level 1 or 2 points to a serious hidden problem, and it is not a routine inspection.

What it costs with us
