Start with the system, not the verdict
A useful report identifies the property, inspection date, appliance, fuel and connected flue. A house may have several flues or a fireplace that has been converted. Check that the report describes the system you asked about rather than treating every opening as one chimney.
Look for the inspection level and the reason for selecting it. A routine service, a home purchase and a suspected chimney fire can call for different scopes. The title 'inspection' alone does not tell you what was examined.
Find the access limitations
The report should tell you which areas were reached and which were not. A concealed joint, inaccessible attic section or blocked camera path is a limitation, not a confirmed defect and not evidence that the hidden area is sound.
Ask whether the limitation affects the decision you need to make. If further access is proposed, request its purpose, cost assumptions, authorization process and who restores any opened materials. More invasive work should have a defined question to answer.
Connect each image to an observation
A close-up is most useful when it identifies a component and location. Ask which appliance the photographed flue serves, where the camera was pointing and what feature the inspector is describing. Dark surfaces or unfamiliar textures alone do not establish a defect.
Good documentation distinguishes an observed crack, corrosion or obstruction from a suspected cause. If the cause is uncertain, the report should say what additional investigation would help rather than presenting an inference as a measurement.
Separate restrictions from sales options
Read any instruction to stop use first and ask what must occur before operation resumes. Then distinguish required correction, recommended maintenance and optional improvement. The company should explain the basis for each category without relying on pressure to approve a large package immediately.
An estimate is not a substitute for the inspection record. Request the findings even if you choose another contractor for repairs. When seeking a second opinion, share the same report and ask the second professional to assess the evidence, not merely beat a price.
Create a closeout checklist
For any accepted repair, retain the scope, materials, completion photos, warranty and applicable permit or inspection records. Ask whether a follow-up assessment is included and how the company documents the condition after work.
Keep the original report alongside the completed-work record. This preserves the difference between what was found, what was authorized and what was actually done. It also helps the next technician avoid repeating an investigation without context.
