Why the inspection scope matters
The word inspection can describe very different amounts of work. A readily accessible visual review is not equivalent to an internal video scan, and neither is the same as opening concealed areas after a serious event or suspected defect.
Ask the contractor to state what areas and components will be examined, how the flue interior will be viewed, and what documentation you will receive.
When a more detailed evaluation may be discussed
A change in appliance or fuel, a property sale, a chimney fire, storm damage, recurring smoke problems or evidence of concealed deterioration can justify a broader conversation with a qualified professional.
- Change in fuel-burning appliance or venting configuration
- Known or suspected chimney fire
- Major weather event or building alteration
- Unexplained odor, smoke, moisture or debris
- Transfer of property or long service-history gap
Turn findings into decisions
A useful report separates observed conditions from recommended work. Ask which items are immediate safety concerns, which protect against further damage, and which are optional improvements. Keep the report and images in your Chimney Health Passport for future comparisons.
Level 1: the baseline examination
CSIA describes three inspection levels. Level 1 addresses readily accessible parts of the system under the applicable inspection scope. It is commonly discussed for continued use without relevant changes, but the professional must determine whether circumstances call for more.
Ask the inspector to identify what was visible, what access was available and what condition was recorded. A statement that the chimney was inspected is less useful than a report identifying the particular appliance and flue. Cleaning and inspection should be described separately even if both occur during one visit.
Level 2 and Level 3: what changes
Level 2 expands the examination and includes internal imaging within its defined scope. Events such as a property transfer, system change or damage concern are reasons to discuss it. The exact requirements should be checked against the applicable standard and circumstances rather than reduced to “a camera inspection.”
Level 3 is discussed when a suspected hazard requires access beyond the earlier levels, potentially including removal of components. Ask what concern justifies that access, which areas will be opened and who is responsible for restoration. More invasive work should have a defined purpose.
Read the limitations before the conclusion
A report can be detailed and still exclude concealed parts of the building. Look for restrictions caused by access, weather, deposits or system configuration. Ask whether a finding is confirmed, suspected or impossible to evaluate without another step.
Keep original images and report identifiers. At the next inspection, ask whether the same area was examined from a comparable position. This makes a claimed change easier to understand and keeps a sequence of reports useful over time.

Questions homeowners ask
Is a chimney inspection included with sweeping?
Practices vary. Ask what visual checks are included with cleaning and whether an internal camera scan or written report costs extra.
Do all inspections include roof access?
No. Access depends on the agreed scope, roof conditions, weather and safety. The report should note any area that was not examined.
When should a chimney be inspected?
Inspection timing depends on use, appliance, fuel and condition. Have the system assessed when there are safety symptoms, after relevant damage or changes, and as part of an appropriate maintenance plan.
