Service · A1 Chimney & Roofing
A Level 3 chimney inspection is the one that opens concealed areas. It is used only when a Level 1 and a Level 2 inspection cannot reach the suspected problem. It is not the default visit.

The work
Walls, chase panels, or the chimney structure may have to be opened to see a flue, a liner, or framing that no camera and no attic hatch can show. That is demolition of a finish, so the location and the reason are explained before anything is opened. The inspection stops at what is needed to see the problem.
Most houses never need this. A sale or a change of appliance is Level 2. A yearly look is Level 1.
Why it matters
Level 3 exists because some defects sit inside a chase or behind a wall, and guessing from the firebox is how the wrong repair gets sold. Opening the right spot answers it.
It is also how you avoid opening a wall that did not need to be opened. The lower levels come first.
What to expect
You are told why Level 1 and Level 2 were not enough, what would be opened, and the price before any finish is removed.
