A targeted investigation when concealed areas may need to be reached to confirm a serious suspected hazard. The contractor should identify the appliance, fuel, chimney construction and access limitations before recommending work. Ask for photographs, written findings and a clear distinction between observed facts, likely causes and optional improvements.

Signals that may justify this service
One sign rarely proves one defect. Document what changed and ask a contractor to explain the inspection or service needed to distinguish possible causes.
- A serious concealed defect is suspected
- Less invasive inspection could not resolve the concern
- Opening construction may be necessary
