Be careful!! There’s a lot more than meets the eye in good wood heating appliance inspections.
For example, there’s a particular item I see with the masonry hearth-wood framed wall “thimble” or “pass through” to an exterior masonry chimney. Although I cannot see through or in the wall, I’ve called this unseen item probably more than 10-15 times in my career. The true determination of the fault requires breaking into the masonry hearth and wood wall. I tell people that if they break into the wall and find that it meets code requirements, I will pay for all their costs…I have yet to pay a cent!!!
